Fang
Fang is the name of different characters appearing in American comic books published by Marvel Comics.

Fang I
Fang is a Lupak who is a member of the Royal Elite of the Shi'ar Imperial Guard. Created by Chris Claremont and Dave Cockrum, the character first appeared in X-Men #107 (October 1977). Fang appears to be a hybrid of an alien and a wolf; he has superhuman senses, strength, speed, stamina, durability, agility, and reflexes, as well as claws and fangs. In recent years, the character has developed new abilities, including teleportation, flight, and energy projection/matter manipulation. (Like many original members of the Imperial Guard, Fang is the analog of a character from DC Comics' Legion of Super-Heroes: in his case Timber Wolf).

He joins the other Imperial Guardsmen in battle against the X-Men on behalf of Emperor D'Ken on a nameless Shi'ar Empire planet. He is attacked by Wolverine, who defeats him and strips him of his costume, using it to sneak up on the other Imperial Guardsmen.

Fang later becomes a "Borderer": a Guardsman stationed on one of the Shi'ar's conquered worlds to help its governor enforce Shi'ar law there. Fang and a small number of other Guardsmen become renegades and turn traitor, betraying the Shi'ar Empire by serving Deathbird in her attempt to overthrow her sister Princess-Majestrix Lilandra. This incident involves Lord Samedar attempting to use some of the outlaw Guard in order to attack the Earth. His faction is opposed by other Shi'ar and the X-Men, the renegade Guardsmen battling the loyal Guardsmen, and Fang fighting Nightcrawler during the conflict. The Brood interfere with a concussion-style bomb secretly hidden in the midst of the battle.

Soon after this incident, Fang is apparently slain when the Brood uses him as a host body for the egg of one of their young on the "Broodworld", former home-world of the Brood. His body is consumed and transformed by the Brood embryo implanted inside him, and the resulting Brood alien later fights Wolverine, who kills it.

When the original Fang is killed, another Lupak, named Nev-Darr, is enlisted to take the place of the original Fang on the Imperial Guard. When that one is killed a third one takes his place.

In Untold Legend of Captain Marvel — which takes place before his first encounter with the X-Men — Fang, the Guard, Captain Marvel, and the Kree face an attack by the Brood. A small division of the Guard — Starbolt, Smasher, Fang, and Oracle — are selected to guard the personage of Deathbird, the current regent of the Shi'ar empire. They ally, then fight with the Kree, after the latter come to their assistance against a murderous attack from the Skrulls.

Fang is seen as loyal Shi'ar warrior when they go to war with the Inhuman-led Kree. One of many battles in this war leads Fang and many others to the base of the Guardians of the Galaxy, a giant floating head called Knowhere.

Fang is one of the many Shi'ar soldiers assigned to team up with the Starjammers to investigate "The Fault," a space-time anomaly that not only threatens Shi'ar space, but all of reality.

Fang reappears years later on Earth. He comes to visit Wolverine, only to discover that his "old buddy" had died. Fang eventually reveals all of his history with Logan to X-23, revealing how he came back to life after being killed by the Brood. According to Fang, the Lupak reproduce through cloning and keep mental templates of their citizens on file. When one of them dies, a new one is made. He reveals to X-23 that while he is not the Fang Wolverine met back in X-Men #107, as a clone, he is still technically the one Wolverine knew.

Fang assists the Guardians of the Galaxy and X-23 in stopping a Brood infestation of a scientific facility.

Tamara Pearson

Fantasia
Fantasia is a fictional character in the Marvel Universe. She first appeared in Captain America #352–353 (April–May 1989), and was created by Mark Gruenwald and Kieron Dwyer. The character subsequently appears as Fantasma beginning in The Avengers #319–324 (July–October 1990).

Fantasia was a member of the Supreme Soviets. The team had been sent by the Soviet government to capture the Soviet Super-Soldiers, who were attempting to defect to the United States. Fantasia disguised the team members with an illusion to appear as members of the Avengers: Red Guardian as Captain America, Perun as Thor, Crimson Dynamo as Iron Man, and Sputnik as the Vision. Eventually, the real Captain America defeated the Supreme Soviets and freed the badly wounded Soviet Super-Soldiers.

Fantasia later changed her name to Fantasma when the team became known as the People's Protectorate. Eventually the team broke up and merged with the Soviet Super-Soldiers to form the Winter Guard.

Fantasma is rescued from a time anomaly by the Winter Guard, with her former teammates of the Protectorate on her trail. It is revealed that Fantasma is a Dire Wraith queen, and she aligns herself with the Presence and fights the Winter Guard. She is defeated by banishing her into Limbo again.

Fantasia is a Russian soldier with super-powers. She is skilled in magic, especially in the use of illusions. She has also shown the ability to fly and certain mental abilities.

Mooster Fantastic
Mooster Fantastic is an anthropomorphic moose and animal version of Mister Fantastic.

Kat Farrell
Kat Farrell first appeared in Deadline #1 and was created by Bill Rosemann. A reporter for the Daily Bugle, Farrell is the co-head of The Pulse, a section of the Bugle which focuses on superheroes.

Initially, Farrell is interested in reporting on 'real' heroes, such as police officers and firefighters, and did not like being forced to cover superheroes.

Following six supervillain homicides, Farrell is led to murdered judge Michael Hart, who presided solely over superhero crimes. Hart's wife had also been murdered. The police suspect that it was a double homicide or Hart had killed his wife first. Farrell discovers that Hart had been murdered by the Tinkerer. He had returned, though, with supernatural powers. Paul Swanson, fellow reporter, breaks into her apartment and kills her fish in an attempt to scare her off the case. Undeterred, she nevertheless decides to drop the story anyway, to protect Hart.

Farrell also participates in the investigation of fellow journalist Teri Kidder's death, and was the first to interview Luke Cage when he brought the villain Green Goblin to justice.

Other versions of Kat Farrell
In the "House Of M" alternate reality, Farrell is still a reporter. She wants to write the truth but meets resistance because the ruling mutant class controls the newspapers. At one point she meets Hawkeye, who is aware that reality has been altered.

Fatale
Fatale is a supervillain appearing in American comic books published by Marvel Comics. The fictional character appears in the comics featuring the X-Men family of characters. She is an assassin who usually works for Dark Beast.

Little is known about Fatale's youth. She is one of Europe's finest assassins and the Dark Beast's most trusted servant. When Dark Beast becomes interested in the X-Man Bishop, he places Fatale undercover as a waitress named Amy Johnson in Harry's Hideaway, a bar the X-Men often visit to gather information for him. There she is able to scan Bishop's mind to find information about his ideal woman and changes her appearance to match this image. She takes the name Pamela Greenwood, but fails to get any closer to Bishop. He notices something familiar about Pamela, but never pursues his interest in her.

After his visit to the Age of Apocalypse, Bishop begins having nightmares. He suspects that the character Pamela Greenwood is somehow connected and goes to her apartment to question her. Pamela reveals herself as Fatale and fights Bishop. However, Dark Beast, monitoring the fight, calls her off when Beast enters the fight. Seeing a new opportunity to infiltrate the X-Men, Dark Beast kidnaps Beast and takes his place.

Several months later in the story, Havok is losing control of his powers. Both Dark Beast and Sugarman order their respective agents Fatale and Scarlett McKenzie to kidnap Havok so that they can brainwash him. Scarlett is able to trick a dazed and confused Havok into coming with her as far as Tokyo, Japan, en route to Genosha, but they are intercepted by Fatale, who has hired the Tatsu clan's ninjas for their help in her mission. Havok is rescued by long-time X-ally Yukio and is reclaimed by X-Factor, who had followed the parties involved to Japan, driving off Fatale and Scarlett after a massive battle. Fatale later helps Dark Beast mask Havok's abduction by Random, by penning a letter to Polaris. They disguise it as a letter from Havok, who has supposedly taken an extended leave of absence from the time and their relationship to try to cope with his problems on his own. When Onslaught attacks the X-Men, Dark Beast reveals himself and offers his services to Onslaught. Dark Beast, Random, Fatale, and a brainwashed Havok form the Dark Descendants and fight X-Factor, but are defeated. Havok and Random escape, but Dark Beast and Fatale are sent to prison. Havok decides that Dark Beast's experiments might still be going on, and he allies himself with the telepath/teleporter Ever and forms a new incarnation of the Brotherhood of Evil Mutants, simply called The Brotherhood. Havok frees Fatale and Dark Beast from prison, telling them that he chose Fatale over Ever and that he wants both of them to join his Brotherhood. Both agreed but Havok disbands the group several weeks later when he discovers Dark Beast's hidden lab. Fatale sides with Dark Beast, but is defeated by Havok.

Fatale is de-powered during the "Decimation" storyline. She later resurfaces in the 2007 "X-Cell" storyline in X-Factor vol. 3, alongside fellow former mutant Blob as part of the terrorist group X-Cell. After Blob attempts to steal food from Multiple Man and Rictor, resulting in a fight between Rictor and Blob, she is forced to step in and attack Multiple Man, recognizing him only after the blow creates a duplicate, one with no moral or physical difficulty with breaking her arm. She stabs the dupe with a concealed poisoned blade, before fleeing. She is later repowered by Quicksilver and the Terrigen Mist, but when she begins to heat up from the effects of the Mist, Abyss flings her and Reaper into the Brimstone Dimension and then follows them. The explosion that would have resulted from the Mist is forestalled by the frozen nature of time in the Brimstone Dimension.

In the 2014 opening storyline of the fourth volume of X-Factor, which stars a new, corporate-sponsored incarnation of that team, it is revealed that A.I.M. scientist Terrance Hoffman managed to extract them from the Brimstone Dimension and capture them, draining them of the Terrigen Mist energies and leaving them powerless once again. He uses the mutants as guinea pigs, performing illegal experiments on them that they regard as torture. Serval Industries sends the new superhero team, X-Factor, consisting of Polaris, Gambit and Quicksilver to Hoffman's base to stop him and rescue the mutants, though they do not know that Fatale, Abyss, and Reaper are among them. Polaris frees Fatale, but Hoffman uses the energy drained from Abyss and Reaper to transform himself into a giant mutate of immense power. Quicksilver and Gambit manage to knock Hoffman unconscious and return him to normal, and when they prevent Reaper and Fatale from killing the unconscious Hoffman, Fatale cannot believe Polaris actually works with Pietro and lets him know about what he has done to her, Abyss, and Reaper in the past, they will never be even.

She soon enough turns her vow into reality, confronting the new X-Factor team during a conference press about the terrible things Quicksilver did under the assumption that it was a Skrull in disguise. Polaris has security take Fatale out, but Pietro holds them back, admitting his crimes in front of the media.

Ferocia
Ferocia is a fictional character appearing in American comic books published by Marvel Comics.

Connie Ferrari
Connie Ferrari is a fictional defense lawyer in Marvel Comics. The character, created by Mark Waid and Andy Kubert, first appeared in Captain America (vol. 3) #20 (August 1999).

Connie Ferrari was a well noted New York attorney. She met and started dating Steve Rogers who, unbeknownst to her, was actually Captain America. Their relationship would soon hit a snag due to Ferrari's continual defense towards criminals, most notably her brother David who was the Answer. When Ferrari found out that Rogers and Cap were one and the same, she felt betrayed and broke up with him. Rogers later worked up the courage to apologize to her and the two parted as friends.

Later, Ferrari became the Avengers' attorney and gained an assistant named Amy. She seems to somewhat regret breaking up with Rogers as she has started dating men who look like him. She discovers that Flatman unintentionally bought the rights to the name Avengers and comes asking to buy them from him. He agrees under the condition that the Great Lakes Avengers be made official members of the team and she begrudgingly accepts. She later bails the team out of jail, after getting arrested over a bar fight, and inducts Goodness Silva as a member, so that she doesn't get prosecuted by the authorities. During a visit to the GLA's headquarters, Connie discovers that the team had kidnapped Councilman Dick Snerd, who was the super-villain Nain Rouge. They later find out that Good Boy had attacked him, leaving him seriously injured, and drop him at a hospital. Connie then tells the team to lie low for a couple of days and stay out of trouble.

Ferret
The Ferret is a Timely Comics character who first appeared in Marvel Mystery Comics #4 (February 1940). He was a generic detective whose only notable feature was his pet ferret, Nosie. He wears a bulletproof vest and carries a gun.

The Ferret appeared in six stories during the Golden Age of Comic Books, in Marvel Mystery Comics #4-9. In 2009, he appeared in the Marvel Mystery Comics 70th Anniversary Special and several issues of The Marvels Project, a limited series.

The Ferret aka Leslie Lenrow was a New York City based private investigator. He often consulted with the police on cases. In one case, he worked with Namor and his companion Betty Dean, the Human Torch and his sidekick Toro, the Angel, and Electro and his creator Philo Zog to defeat Nazi Dr. Manyac, his green flame robots, and Project: Blockbuster, a giant version of the green flame robots.

In 1940, during a seemingly routine missing persons case, the Ferret and Nosie tailed a Professor Hamilton to a nondescript brownstone. In reality, Hamilton was a Nazi spy named Albrecht Kerfoot and the brownstone was a meeting place for spies. The Ferret was caught and stabbed in the heart with a dagger. His body was found by the Angel, who adopted his pet ferret and trailed the spies, eventually working with Captain America and Bucky to defeat them.

Fever Pitch
One of the Morlocks

Fiery Mask
Fiery Mask (real name Jack Castle) is a fictional character appearing in American comic books published by Marvel Comics. He was a Golden Age superhero created by Joe Simon and first appeared in Daring Mystery Comics #1 from Timely Comics.

He first appeared in Daring Mystery Comics #1, then in issues #5–6 and then in Human Torch Comics #2. He returned in 2008 in The Twelve. Chris Weston has referred to him as "Marvel's Green Lantern."

Fire-Eater
Fire-Eater is a fictional character appearing in American comic books published by Marvel Comics.

He uses incendiary "inferno discs" designed by himself and the Clown. He works for the criminal organization, the Circus of Crime.

Flashback
Flashback (Gardner Monroe) is a fictional mutant character appearing in American comic books published by Marvel Comics. His first appearance was in Alpha Flight #1.

Gardner Monroe was born in Manitoba Province, Canada. Possessing the mutant ability to summon duplicates of himself from future timelines, Monroe was recruited by Department H, a fictional branch of Canada's Department of National Defence concerned with training superhumans as government agents. Given the code-name Flashback, Monroe progressed through the initial Gamma Flight training program and had advanced to the second-tier Beta Flight team before Department H as a whole was shut down by the Canadian government. While the primary team, Alpha Flight, continued to operate without government support, the members of Gamma and Beta Flights, including Flashback, were dismissed.

Some time later, Flashback was recruited, along with other disenfranchised members of Gamma and Beta, by Jerry Jaxon and his robot assistant Delphine Courtney into Omega Flight, a team put together to gain revenge on Department H's founder and leader of Alpha Flight, James MacDonald Hudson. Though Omega Flight was defeated, the encounter ended with Guardian's apparent death. During Alpha Flight's second encounter with Omega Flight, one of Flashback's duplicates was killed by a construct created by Madison Jeffries after Courtney used it as a shield against the construct's attack, causing all other duplicates present to vanish. Upon the realization that his duplicate's death would mean his death in the future, Flashback fell to his knees in shock while Jeffries dealt with the remaining Omegans and destroyed Courtney. Flashback and his teammates were left under guard by Jeffries' construct until the police arrived to apprehend them.

Some years later Alpha Flight was informed that Flashback had disappeared from prison, and was presumed dead. Years later, Flashback resurfaced, and tried to redeem himself by destroying his costume, reasoning that if he didn't have his costume he couldn't be sent back to his death. Then one morning Flashback woke up to discover his costume hanging in the bathroom. This version however had the same design as the ones worn by his duplicates. Flashback soon discovered that no matter what he did, he kept on finding himself in the duplicate suit. In desperation, Flashback contacted Sasquatch and his Alpha Flight team and convinced them to help him. The Alpha Flight member Nemesis came to the conclusion that she would have to kill him with her enchanted blade in order to stop him from dying in the future. After much trial and error Alpha Flight managed to keep Flashback from being sent to the past.

Flashfire
Flashfire, originally code-named Tempest, is a member of the Shi'ar Imperial Guard. The character, created by writer Chris Claremont and artist Dave Cockrum, first appeared in Uncanny X-Men #107 (October 1977). Flashfire can generate and fire bursts of light and electricity. Like many original members of the Imperial Guard, Tempest/Flashfire is the analog of a character from DC Comics' Legion of Super-Heroes: in his case Lightning Lad. Flashfire's alter-ego is Grannz; Lightning Lad's is Garth Ranzz. At one point, Grannz was engaged to marry fellow Guardsman Oracle (an analog of Saturn Girl, to whom Lightning Lad was also romantically linked).

Part of the division of the Imperial Guard known as the Superguardians, Tempest is amongst the first of the Imperial Guard encountered by the team of superhuman mutant adventurers known as the X-Men who sought to rescue the Princess-Majestrix Lilandra Neramani from her insane brother, then-Majestor D'Ken. After the battle, Lilandra takes over as Majestrix, and the Guard swears allegiance to her.

Deathbird's second attempt at a coup is successful, and she becomes Shi'ar Empress. Tempest is with the Guard when they come into conflict with a rogue Space Knight named Pulsar and an alien named Tyreseus. After a large battle which also involves Rom and other Space Knights — which leads to the deaths of four new Guardsman — Pulsar and Tyreseus are defeated.

Empress Deathbird commands the entire Imperial Guard, including Tempest, to fight the combined forces of the Starjammers and Excalibur on Earth so that she can claim the power of the Phoenix Force for herself. The Guard are forced to retreat when Deathbird is put in danger. (Some time later War Skrulls impersonating Charles Xavier and the Starjammers depose Deathbird and restore Lilandra Neramani to the throne. Deathbird cedes the empire back to Lilandra as she has grown bored of the bureaucracy.)

Tempest is again part of the mission during Operation: Galactic Storm, an intergalactic war between the Shi'ar and the Kree. The Imperial Guard are integral to the Sh'iar creating a massive super weapon — the "Nega-Bomb" — using Kree artifacts, including the original Captain Marvel's Nega-Bands, which the Guard steals from the dead hero's tomb. This bomb is capable of devastating an area equivalent to that of the Kree Empire (which is supposedly located throughout the Large Magellanic Cloud). Ultimately, the Nega Bomb device is successfully detonated, devastating the Kree Empire, with billions dying instantaneously (98% of the Kree population). The Shi'ar annex the remnants of the Kree Empire, with Deathbird becoming viceroy of the Kree territories.

Tempest is renamed Flashfire in the first issue of the Imperial Guard limited series, because of the pre-existing DC character named Joshua Clay (Tempest).

Flashfire has many further adventures with the Imperial Guard, in storylines involving Ronan the Accuser and the Inhumans, and such storylines as "Emperor Vulcan," "Secret Invasion," "X-Men: Kingbreaker," "War of Kings," "Realm of Kings," the "Infinity" crossover, the "Trial of Jean Grey," "Time Runs Out," and the return of Thanos.

Flex
Flex (Adrian Corbo) is a superhero appearing in American comic books published by Marvel Comics. He is a former member of the superhero team Alpha Flight, but later got downgraded to Beta Flight.

Adrian and his older half-brother Jared (later codenamed Radius) were raised in the Hull House orphanage, which was actually a facility operated by the Government of Canada's secretive Department H. While Adrian became shy, reserved and bookish, Jared became athletically inclined, aggressive, and arrogant. Both brothers manifested mutant powers after puberty: Adrian gained the ability to transform parts of his body into blades, while Jared manifested a personal force field that could not be shut down. The brothers were recruited into a new incarnation of the Canadian superhero team Alpha Flight.

This incarnation was being heavily mentally controlled by Department H, led by Jeremy Clarke. As part of this, the team was led to believe that Wolverine had murdered the ex-Alpha Flight member Box. Flex was one of the team sent to stop him, which they did on a heavily forested back road in New York. Wolverine initially faces down the team, discussing things and using his senses to check them out. Flex becomes very nervous, despite his brother's bravado. Despite the efforts of both sides, a fight breaks out and it is soon joined by several more X-Men. Flex is personally confronted by Cannonball and loudly declares his desires to talk, not fight. Cannonball, always willing to do the same, does so and the two manage to get the fight to end. The fact that Wolverine had no adamantium at the time they were tracking him made the entire Alpha Flight team recognize something was wrong with the entire scenario. Radius and Flex assist the new Alpha Flight in battling several foes, including the Zodiac and the Brass Bishop.

During the Brass Bishop incident, the team encounters a church full of zombified townspeople. Flex's teammate Man-Bot reports no life signs, other than the church-goers but a scared little girl emerges from the crowd. The team follows her directions, flying off to where the girl said all the people had gone. While mid-flight, Flex is the one to realize that Man-Bot did not register the girl's vital signs. His warning saves the team from flying nose-first into a mysterious, shielded structure. The team eventually fought the malicious, mind-controlling leader of Alpha Flight, Jeremy Clarke. He later died of radiation poisoning during a Zodiac raid on the Department H headquarters, to be replaced by a new, kinder administrator. A reorganized Alpha Flight team confronts several members of the original Flight and later team up with them to defeat a new Weapon X, who had been created by a rogue Department H scientist. Both groups of Alphas merge into a unified Alpha Flight following this adventure. The Corbo brothers and several other members of the new team were later reassigned to Alpha Flight's trainee team, Beta Flight.

After the events of M-Day, Corbo lost his mutant abilities. His current whereabouts are unknown.

Flexo the Rubber Man
Flexo the Rubber Man is a robot created from a form of "live" rubber that was later retcon to have been a Symbiote and appeared in Mystic Comics #1–4.

Flint
Flint (Jaycen) is an Inhuman in Marvel Comics. The character, created by Charles Soule and Joe Madureira, first appeared in Inhuman #3 (October 2014).

Flint was Jason, a young African-born American boy who was adopted by Martin (a white man and his wife). Though Jason loved his parents, he felt out of place, mostly because in the community he grew up in he was the only black person. One day, the Terrigen mists arrived and Martin, who was actually an Inhuman, told Jason to embrace their destiny. Jason emerged from his cocoon and was immediately recruited by Lash. He is renamed Korvostax and forced by Lash and the rest of his team to fight the Royal Family, feeling that they were unworthy of being Inhumans. Lash was defeated by Medusa and Jason opted to join the Inhumans in New Attilan. During the fight, he discovered that he had geokinesis, the ability to control the earth and rocks, and could also encase himself in a rock-like body.

While in New Attilan, he learns that his biological family is still in Africa. Soon after he takes the Flint name, Jason finally visits his birthplace Utolan, and discovers his biological mother Irellis and sister Ikelli. Out of respect, Jason changes the spelling of his name to Jaycen. He also starts a relationship with fellow Inhuman Iso.

Flint accompanies Crystal's team in investigating the strange skyscrapers in China. When the skyscraper causes Collective Man to lose his powers and split into the five brothers, one is nearly killed by Flint.

Flux
Flux is the name of two different characters appearing in American comic books published by Marvel Comics.

Benjamin Tibbits
Private Benjamin "Benny" Tibbets was a Private First Class in the United States Army and a soldier with unresolved mother issues. He, along with a platoon of soldiers, were exposed to a gamma bomb by General Ryker, who wished to test its effects on humans. Tibbets was the sole survivor. He was transformed into a Hulk-like creature with superhuman strength. The only differences were that Tibbets, nicknamed Flux, looked more misshapen, his forehead and joints significantly more pronounced, and his transformation was more erratic, parts of him sometimes transforming while the rest of him remained human. Convinced by Ryker that Bruce Banner was responsible for his condition, and had sold gamma technology to the Iraqis, Flux was sent after the Hulk, but the fight proved one-sided and Banner was able to talk him down. Tibbets underwent psychiatric evaluation thanks to Doc Samson, but he was subsequently recaptured and broken by Ryker. Regressed to a childlike mentality and vocabulary, apparently perceiving Ryker as his 'mommy', Flux was once again pitted against the Hulk, but the fight ended when General Ross forced Ryker to stand down. Without Ryker's commands, Flux stopped fighting and broke down, reverting to Benny as he wept for his mother.

Recently, Flux was revealed to be in A.I.M.'s custody, who experimented on him. However, he was killed by Grey of the Gamma Corps during a raid on the A.I.M. base.

During the "Damnation" storyline, Flux was cast down into Hell after his death and is one of the damned souls who Johnny Blaze and Zarathos encounter there alongside Elephantine, a Jack O'Lantern, and Richard Fisk.

Dennis Sykes
Dennis Sykes is a banker who appeared in the story 1 Month 2 Live. He gains superpowers and an untreatable cancer following an accident with toxic waste. With a life expectancy of barely a month, Sykes launches himself on a brief career as a superhero, in an attempt to make a difference in the world while he still can, assisting the Fantastic Four in saving Ego the Living Planet from a cancerous infection and averting Hammerhead's attempt to take control of his neighborhood. Although use of his powers made his condition worse, Sykes makes a positive impression on many heroes with his dedication to doing the right thing, accepting training from Spider-Man and receiving honorary membership with the Fantastic Four and the Avengers before he finally dies of stress from his final battle. His wife was by his side when he died. To honor him, a statue of Flux was erected at the children's hospital he helped after getting his powers.

Flux in other media
The Benjamin Tibbets version of Flux appears in Hulk, voiced by Lee Tockar.

Foxbat
Foxbat is a fictional character appearing in American comic books published by Marvel Comics.

Like some of the members of the Riders of the Storm, he is an Inhuman who originally came from Attilan and joined the team unwillingly when Apocalypse captured half of the city. After the city was liberated by the X-Men and Black Bolt, he retained membership in the team as he, like the others, was a deep believer in Apocalypse's Social Darwinism and wanted to rid the world of those unworthy.

The Riders of the Storm, now going by the name Dark Riders, came under the leadership of Genesis. Genesis judged Foxbat unworthy of living. Chastised by his own teammates, Foxbat fled but was recaptured, and Genesis drained his lifeforce. Any hope of resurrecting him was lost when his remains were destroyed during the conflict between Genesis and his father, Cable.

Foxfire
Foxfire is a fictional character appearing in American comic books published by Marvel Comics.

Olivia Underwood was born in Nexusville, New Brunswick, in the United States of Earth-712. She later became a criminal and supervillain using the alias Foxfire. She was a member of the Institute of Evil, a criminal organization opposed by the superhero team called the Squadron Supreme. This was complicated somewhat by the fact that Foxfire was in love with Squadron member Doctor Spectrum, although he did not seem to return her feelings.

She was among the Institute of Evil members who battled the Squadron Supreme in their final attempt to destroy the heroes. When the Institute of Evil was captured by the Squadron and its members mind controlled by the Behavior Modification device, Foxfire and the other former super-criminals became members of the Squadron, to assist them in their efforts to forcibly turn the world into a Utopia. Her criminal record was pardoned, and she became a public crusader and government superhero. She accompanied Hyperion to supervise the behavior modification process at a prison. She finally later began a relationship with Doctor Spectrum.

The hero named Nighthawk opposed the Squadron and formed a rebel group, the Redeemers. He undid the Behavior Modification of Foxfire and several others, and recruited them into his group.

During the final battle between the Redeemers and the Squadron at Squadron City, Foxfire, who was still in love with Doctor Spectrum, tried to gain his approval by betraying Nighthawk, thus allowing the Squadron to win the fight. She used her powers to kill Nighthawk by blasting his heart. Foxfire was then killed by fellow Redeemer Mink, who had been in love with Nighthawk, when she was stabbed through the heart by Mink's artificial claws. The death of Nighthawk caused the Squadron members to realize that they had become the very thing that they had intended to oppose, and thus ended the fight, though not in the way that Foxfire had intended.

Spider-Man villain
A drug addict nicknamed Freak is chased down by Spider-Man after attempting to steal from the poor at the soup kitchen where Spider-Man's Aunt May works. Freak stumbles into a laboratory owned by Curt Connors and injects himself with animal gene fluids, thinking that they are crystal meth. A chrysalis forms around Freak's body, and he later emerges as a skinless monster. After being shot at by police, he falls into the sewer and forms another chrysalis. Emerging as an animal hybrid and completely bulletproof, Freak tracks Spider-Man by his scent. After a violent confrontation, Freak gives in to his addictions and finds a meth lab. Spider-Man follows him. During the ensuing fight, the building is set ablaze. Freak is caught under the flaming debris, but survives and creates a new chrysalis, which has made him fireproof and even stronger. Freak emerges as an armadillo-like creature and again tries to kill Spider-Man. When Connors arrives with the quicklime necessary to incapacitate Freak, Spider-Man tricks him into thinking Connors has drugs. Freak tears open the bags and is covered in the quicklime. He again forms a chrysalis, with Spider-Man pouring quicklime over it, to permanently incapacitate him. The chrysalis is taken by a hazmat crew — which is later revealed to be an Oscorp research group.

Freak is next seen cut open and hooked up to machines in an Oscorp lab where scientists are using his unique abilities to cure various diseases. Norman Osborn injects him with a sample of the anti-venom antibodies to create "super-venom", a virus capable of killing millions with a single drop. He then uses the super-venom to re-power Mac Gargan who was "cured" of his symbiote by Anti-Venom. Osborn also mentions that Freak is incapable of becoming intoxicated because his body has adapted to his drug addiction by removing the pleasure center of his brain. In the confrontation between Spider-Man and Osborn, Osborn activates the building's self-destruction with Freak still inside. A search afterwards by Oscorp reveals "no signs of life", which made the team reason that Freak was killed, with Osborn immediately retorting, "Idiot. Think about it for a second".

During the "Origin of the Species" storyline, Freak is invited by supervillain Doctor Octopus to join his team in exchange for securing some specific items for him. Freak goes after Spider-Man for Menace's infant. He collides with Vulture (Jimmy Natale) before Rhino arrives. Spider-Man goes on a rampage against the villains after the infant is kidnapped from him by the Chameleon, and Spider-Man defeats Freak.

During the "Absolute Carnage" storyline, Freak was freed from Ravencroft upon its destruction. Alongside Will O' The Wisp and Conundrum, Freak was bonded to a copy of the Grendel Symbiote. He was apparently killed during his fight with Deadpool when his body overtaxed itself to adapt to Deadpool's attacks. In the pages of the "Ruins of Ravencroft", Freak turns up alive and appears as an inmate at Ravencroft following its rebuilding.

Kevin
In X-Force #101, a young mutant known as Kevin, nicknamed Freakshow, nearly fell to his death when attempting to impress others his age by proving that he could fly. This occurs when the High Evolutionary temporarily eliminates all mutant abilities.

Genoshan
Freakshow is one of the few survivors of the island of Genosha after the Sentinel attacks on the capital of Hammer Bay. Freakshow is the traveling companion of Wicked and becomes an unofficial pupil of Professor X. He soon proved his usefulness in dispatching a skirmish between the Professor and the local bully Unus the Untouchable. Knowing that he couldn't do anything to harm Unus, Xavier had Freakshow swallow the man whole. Because of Unus' natural force field he was unharmed, albeit shaken when Freakshow vomited him up later. He helps Wicked survive an attack by Magistrates, military forces who were once the murderous law-enforcement arm of the Genoshan government. During their efforts to rebuild Genosha, Freakshow takes on a worm-like form and digests the debris of many shattered buildings to turn it into arable land.

After the events of the House of M, Freakshow is revealed to be one of the many mutants to lose his abilities as a result of the Scarlet Witch's decimation. He has been seen with a number of Genoshan mutants, including Unus the Untouchable and Wicked. In Son of M #5, (June 2006) the traveling mutant Quicksilver convinces him to try the mutagenic compound called the Terrigen Mists, which had been stolen from the Inhumans. Freakshow regains his powers, but for some time, he is unable to change out of his large, monstrous form. While trapped like this, he and the other Genosha mutants are drawn into battle with the Inhumans, who are tracking down Quicksilver. Some time after, the effects of the mist wear off.

Freebooter
Freebooter (Brandon Cross) is a fictional character who appeared in the Marvel Comics' series A-Next. He was created by Tom DeFalco and Brent Anderson, and first appeared in A-Next #4 (1999).

Brandon Cross was a protégé of Hawkeye and Swordsman. He was invited to join the "Dream Team" of new Avengers who were going to become members of A-Next. Donning a Hawkeye-like costume, he assumed the guise of the roguish "Freebooter".

Freebooter quickly displayed a tendency to promiscuous and charismatic, and poured on the charm for teammate Stinger and found her totally unreceptive to him. Stinger was outraged that new Avengers were being added to the team without her knowledge or permission, and felt no desire to fraternize with the new recruits (especially Freebooter), but in due time Freebooter's fighting skills earned her respect, and his heroic, chivalrous nature her affections. He became a valuable member of the team, but tragedy struck when his close friend and fellow "Dream Teamer" Crimson Curse was killed in the line of duty. Freebooter lost his carefree attitude and became more withdrawn, but he still fought the forces of evil in her honor.

During the events of Last Planet Standing, Freebooter was badly injured, but received help from the former villain Sabreclaw, whom he later convinced to join A-Next while he was recuperating. Freebooter later returns to active Avengers duty.

Freebooter has no powers, but has outstanding swordsmanship skills and is an expert archer. His weapon of choice is a retractable bo staff.

Freya
Freya is an Asgardian and goddess of fertility based on the Norse deity of the same name. She appears as a supporting character of Thor. Freya first appeared in Thor #321 (Oct. 1993) and was created by Bill Mantlo and Don Heck. Freya used to work as a former Valkyrie. The people of Asgard have started a cult that worships her on the Isle of Love. On one occasion, Rimthursar lied to Freya stating that Odin has died in order to trick her into crying so that Rimthursar can collect her tears. Freya had an artifact named after her called the Cloak of Freya which Loki once used to turn Storm into a falcon.

Freya's history was later retconned where she was the daughter of the Giant Thyrm and her position was given to the similarly-names fellow goddess Freyja. Thyrm once tried to get Thor and Loki to give him Mjolnir in exchange for Thor's hand in marriage to Freya. Thor and Loki were able to outwit Thyrm. Freya has the various superhuman attributes that the other Asgardians have. She can also speak in the languages of the Nine Realms.

LeBlanc, a man with Olympic-level leaping skills and a former military frogman, is among those recruited by the Organizer, secretly a candidate for the New York mayorship, to form the Ani-Men. Because of his abilities and background, LeBlanc was given a frog-resembling costume. The team goes on missions to undermine the current administration. Daredevil defeats them and they all go to prison. The Ani-Men later work for Count Nefaria, whose scientists submit the unwitting Ani-Men to processes that temporarily give them superhuman powers and animal-like forms. LeBlanc gains superhuman strength and stamina, along with frog-like legs. They invade the Cheyenne Mountain missile base and fight the X-Men. After they lose their powers the team is sent to kill Tony Stark, themselves dying by a bomb that Spymaster had planted to kill Stark.

Unnamed Frog-Man
During the Secret Wars storyline, a second Ani-Men version of Frog-Man, alongside a third Ape-Man and a third Cat-Man, went on a crime spree when the heroes were on Battleworld. They somehow got the equipment of the original Ani-Men and used it to rob a vault wagon only to be opposed by the NYPD.

Carmilla Frost
Carmilla Frost is a freedom fighter and member of Killraven's Freemen in a post-apocalyptic alternate future of the Marvel Universe.

The character, created by Don McGregor and Herb Trimpe, first appeared in Amazing Adventures (vol. 2) #21 (November 1973) and continued to appear in most issues of the title through #39.

Carmilla is from an alternate-reality Earth run by Martians. In 2001, she and her father Andre are taken to the Martians' Yankee Stadium Genetic and Clonal Complex. Andre is blackmailed with threats to his daughter into helping the Martians in performing cloning research. In 2004 she begins assisting her father in his experiments, and eventually becomes an expert molecular biologist. By 2010 she becomes the youngest human designated as a Keeper by the Martians. In 2014 she refuses to conduct cloning experiments on other humans, but two years later, after a Martian Overlord kills Andre, she agrees to clone his corpse in an attempt to restore him to life. Her efforts fail, instead producing the mutated creature Grok. In 2018 she helps Killraven escape from captivity from the Yankee Stadium Genetic and Clonal Complex and joins his Freemen. In 2020 she learns that she is pregnant with the Freeman M'Shulla's child.

She and her newborn son Skar are rescued by the cross-reality traveling Machine Man and Howard the Duck.

Christian Frost
Christian Frost is the brother of Cordelia, Adrienne and Emma Frost. He was created by Grant Morrison and Phil Jimenez and made his first appearance in New X-Men #139 (June 2003).

Not wanting anything to do with the family business, Christian often clashed with his father Winston. When Winston learned that his son was gay, he threatened to disown him and forced Christian to dump his then-boyfriend and move into the family home with him. Christian refused and cut ties with his entire family, only remaining in contact with Emma, his closest confidante. In retaliation, Winston used his power to have Christian's boyfriend deported, leading Christian to develop a substance abuse problem as a way to cope with the resulting depression. As his addiction worsened, a concerned Emma asked their father to help him get clean and Winston gladly welcomed his son back before turning on him and locking him in a mental institution in order to "cure" him of being gay once Emma had left. Following the conversion therapy, Christian was released and reinstated as the heir to the Frost business. Christian subsequently murdered Winston as revenge for the years of abuse his father had subjected him to and took over his business empire.

After becoming suspicious that her father had appointed Christian as heir to the business, Emma visited his mansion and was greeted by her father. Demanding to see Christian, Winston refused and exhibited never-before-seen psychic powers to force her to retreat. Worried for her brother's safety, Emma approached Iceman and he agreed to help rescue Christian from her father. When they returned to the mansion, they fought through several psychic apparitions before discovering Winston's body in his study. While Iceman bought her time, Emma reached out and discovered that Christian was the one causing the apparitions, including that of their father. Emma's attempts to reach Christian's mind were in vain as, in the midst of a mental breakdown causing him to lose control of his powers, Christian was unable to hear her. As the Frost siblings were unable to directly infiltrate each other's minds, Emma created a telepathic link between Iceman and Christian, allowing them to communicate. Iceman, having recently been outed, empathised with Christian's homophobic experiences and managed to calm him down enough for him to regain control. Emma thanked Iceman and decided to stay with her brother to help him come to terms with what had happened and get him back on his feet.

After the mutant nation of Krakoa is formed, Emma re-establishes the Hellfire Club as the Hellfire Trading Company which aims to help distribute supplies in service of mutants, with Emma once again as its White Queen. Emma brings Christian into the fold, appointing him as her White Bishop. Christian begins to become closer with Iceman through his work for the Company and the two begin a casual relationship.

Powers and abilities
Unlike his siblings, Christian's psychic powers did not emerge when he was younger and appear to have developed much more recently. He has the ability to draw upon and materialize energy from the astral plane and create Avatars of energy constructs or project it as a destructive psionic energy blast which causes both physical and mental damage. His newly manifested abilities are extremely powerful, as his projection of Winston was robust enough to convince Emma, herself a particularly advanced telepath, that it was her actual father.

Frost Pharaoh
Frost Pharaoh is a fictional supervillain appearing in American comic books published by Marvel Comics. He was created by Saladin Ahmed and Javier Garrón, and first appeared in Miles Morales: Spider-Man #4 (March 2019).

Frostbite
Frostbite is a fictional character appearing in American comic books published by Marvel Comics.

Dr. Sloan Alden ran a cryogenics institute where the wealthy and dying would be frozen. As a result of the Zodiac draining of New York's energy, Alden's own cryo-chamber drained power from the others, as well as a back-up generator, to keep him alive. The side-effect granted him the ability to generate and control ice as well as creating things like ice walls and ice storms.

Frostbite in other media

Markley
When he was a child, Markley discovered he had the mutant ability to persuade people into doing whatever he wanted, simultaneously manipulating their senses. Using his power, he made millions, using his money to develop systems to enhance his abilities even further, to the point where he became- in his own words- a "more-than-perfect killing machine".

Futurist
Futurist (Randolph James) is a fictional character appearing in American comic books published by Marvel Comics.

Dr. Randolph James was a scientist who evolved himself into a large-skulled, highly intelligent humanoid with great psionic abilities. Randolph James was a classmate and friend of Reed Richards, who later became Mister Fantastic. He later became a professor and research scientist though he became somewhat unstable when his wife died.

Years later Reed and his team, the Fantastic Four came to visit Dr. James. Right after the Fantastic Four departed, a group of young thugs broke into Dr. James' home and robbed and assaulted him. Dr. James tried to call the Fantastic Four, but they were busy fighting Blastaar. Fearing his own demise, Dr. James in his desperation used his evolution-accelerator to heal the severe trauma he received. When Mister Fantastic returned, he found his friend transformed into the Futurist. The Futurist discovered the gang that had attacked him still lurking in his neighborhood, and turned them into rats. The Futurist floated towards the Fantastic Four's headquarters, the Baxter Building, displaying his raw power along the way. Once there, Blastaar tricked the Futurist into making an alliance with him, convincing the Futurist that the Fantastic Four were dangerous and needed to be destroyed. Blaastar and the Futurist broke into the Baxter Building, placing the Invisible Woman into a deep slumber. The Futurist sensed Blastaar's evil intent, and allowed Franklin Richards to send Blastaar back to the Negative Zone with his psychic powers. The Futurist left the Earth, seeking out new vistas of exploration in outer space.

Quasar briefly glimpsed the Futurist, first on the Stranger's Labworld, and then during his journeys in the cosmos. From what Quasar saw, the Futurist seems to be paired with another highly evolved humanoid, named Alpha the Ultimate Mutant.
