Main

 * Kaz (portrayed by Bradley Steven Perry) is Oliver's best friend. He is lazy in school and, while devoted to Oliver, he will often try to get away with a shortcut that ends up getting both him and Oliver into trouble. While he seems stupid sometimes, he can unexpectedly come up with a smart solution to a problem. It was revealed by Jordan in "Alan's Reign of Terror" that he has 11 siblings. In "Mighty Mole", it's revealed that Kaz's full name is Kazimeras. At the end of "The Mother of All Villains", exposure to the Arcturion gave Kaz and Oliver superpowers.
 * Oliver (portrayed by Jake Short) is Kaz's best friend and puts up with his flaws because he sees good in him. He is intelligent, sweet, and sarcastic, the perfect yin to Kaz's yang. He is also in love with Skylar. He apparently has a fear of elbows, as shown in "Mighty Mole". In "Living the Dream", Oliver operated by Quimby Fletcher to have Ambrose write a story about his dream of the Arcturion. In "The Mother of All Villains", Oliver discovers that his mother Bridget is actually Mr. Terror. At the end of the episode, exposure to the Arcturion gave Oliver and Kaz superpowers.
 * Skylar Storm (portrayed by Paris Berelc) is a superhero from the volcano planet Caldera and Oliver's love interest. Besides having peak human condition, Skylar has 24 superpowers include X-ray vision, explosive induction, laser vision/heat vision, telekinesis, portal creation, gyrokinesis, manipulation of celestial bodies, size alteration, paralysis inducement, flight, super strength, intangibility, camouflage, invisibility, petrification, space survivability, and super speed. She recently lost her superpowers and her invisible fling motorcycle in a battle against her nemesis, Annihilator, and is now a normo patient at Mighty Med, where she is working to find a way to regain her superpowers. However, she still has amazing hand-to-hand combat skills, along with enhanced physical attributes, which can even become useful against super-powered beings. As a normo, she goes by the alias of Connecticut "Connie" Valentine when attending Logan High School. In the first-season finale, she regains her powers. However, she falls under Annihilator's control due to her tampering with them, giving her several more powers like the Kiss of Death. While the Annihilator is at Mighty Max, Skylar is being used by the Annihilator to use a secret formula that turns superheroes into super villains. In "Storm's End", Skylar becomes evil enough to execute a powerful attack on the Annihilator and begin her own plans of conquering the galaxy. Using coal, Oliver tricks Skylar into thinking that he has given up as Hapax removes the corrupted powers from her. A weakened Annihilator shows up and uses Black Widower's poison power as Hapax transports Kaz, Oliver, and Skylar back to Mighty Med to get an antidote. Horace and the doctors work to keep Skylar from dying. After Skylar flatlines, Horace uses his abilities to revive her. In "Saving the people who save People" She uses the catchphrase "There's a storm coming... Skylar Storm" when fighting Megahertz in Mighty Med.
 * Alan Diaz (portrayed by Devan Leos) is the nephew of Horace. He slightly dislikes Kaz and Oliver because of their status as normos, so he does everything in his power to get rid of them. Although there are some occasions where he helps Kaz and Oliver. He seems to like Kaz a little more than Oliver, as shown in "How the Mighty Med Have Fallen" when they were trapped at Mighty Max. He is always seen wearing a sweater vest, and it's suggested in "Lair, Lair" that he wears several sweater vests on top of each other. His power is telekinesis. In "Growing Pains", it is revealed that when Alan gets scared, he either turns into an animal or sprouts an animal body part. He also has the ability to turn other people into animals, as seen in "Mighty Mole". He apparently doesn't know the difference between a circle and a triangle and is bad with grammar due to his lack of education. In "The Mother of All Villains", Alan tries to find a good wedding gift for Bridget and Horace, which leads to him unknowingly obtaining the Arcturion. During the wedding, he ends up learning that Optimo is his father. At the end of the episode, it is discovered that Alan's grandfather is Hapax the Elder.
 * Gus (portrayed by Augie Isaac) (recurring season 1, starring season 2) is Kaz and Oliver's friend, but is unaware of their secret job. He is very quirky, sometimes unlikable, and lacks normal social skills. Over time, a crush on Jordan appears to have revealed itself. Gus' character started out as recurring, but became a series regular in the second season. Throughout the whole series, it has been mentioned that his family is rich, even capable of buying The Domain, as seen in "Are You Afraid of the Shark?" He always keeps strange things in his backpack or wallet. In "Stop Bugging Me", it is revealed that Gus owns a cheetah. In "The Dirt on Kaz & Skylar", it is revealed that Gus owns a bobcat.

 * Ambrose (Oliver Muirhead) is a member of Mighty Med's comic book department. He has the power to see visions of other heroes' lives, allowing him to write and illustrate incredibly fast. Ambrose agrees with Kaz and Oliver's idea to fudge some details to boost sales. He also does not seem to be paid well since he has to use a saw to sharpen his pencils. He was mentioned in "Storm's End", where Kaz had to change the expressions of his face from scared to not scared just in case Ambrose got a vision of the fight between Annihilator and Hapax. In "Living the Dream", Ambrose gets a new drawing table in the form of Lizard Man. When Oliver tells Ambrose about Kaz's dream of the Arcturion, Ambrose takes Oliver's suggestion to give Oliver the alias of Quimby Fletcher. He later helps Oliver into locating Kaz after he was abducted by Mr. Terror's minions.

Superheroes

 * Tecton (portrayed by Jilon VanOver) is Kaz's favorite superhero who is a parody of Superman and Hyperion. He has superhuman strength and speed as well as flight, immunity to pain, and the ability to cause tectonic activity with a stomp of his foot. He is also capable of healing at a rapid rate, but if exposed to a gas that only exists when delta radiation mixes with gold, he will not be able to heal. In "So You Think You Can Be a Sidekick", Oliver was his sidekick until Alan took his place. In "Lair, Lair", Tecton and Skylar Storm are converted into supervillains by a formula made by the Annihilator that was used by Skylar.
 * Solar Flare (portrayed by Carly Hollas) is a female superhero with pyrokinesis and pyrogenesis. Although the most recurring of the superheroes, Solar Flare has yet to have a speaking role. She is actually the second Solar Flare since there was a Solar Flare that was around back in the 1950s.
 * Incognito is an invisible superhero. Nobody knew what he looked like until the episode "Copy Kaz". His appearance is a white-faced human with silver clothing, ginger hair, and an eye-patch.
 * Blue Tornado (portrayed by Brett Johnson) is a superhero with atmosphere manipulation, which allows him to spin at the speed of sound and shoot lightning from his hands. Kaz saw him in disguise and recognized him, which is what led him and Oliver to Mighty Med. In "Mighty Mole", Blue Tornado and Neocortex are converted into supervillains by a formula made by the Annihilator that was used by Skylar. He is a parody of the DC Comics superhero Red Tornado.
 * The Crusher (portrayed by Jeffrey James Lippold) is the strongest man in the universe, capable of hurling someone across a room just by giving them a high-five. He was the first superhero to have his life saved by Kaz and Oliver, in which they shocked his feet to give him cardiac aid. According to Tecton, his real name is Glenn Crushman. Near the end of the first season, the Crusher gets married; however, his wife doesn't like him doing anything dangerous.
 * Brain Matter (portrayed by Napoleon Ryan as a human and Troy Brenna as a monster) was once a hero with superhuman intelligence, which he used to create weapons, but he grew envious of superheroes with other powers. He created a serum that would give him more powers, but the experiment backfired and went horribly wrong—the serum turned him into a large, blue-skinned monster with super-strength, and his only thought was to eat brains. He was shrunken and locked in Mighty Med's freezer, but years later Kaz and Skylar released him, causing his monster form to go on a rampage, until it fell into a coffin with dry ice in it. He reappears in "Growing Pains" where he has been cured of the serum and given all the powers he intended to give himself, along with the ability to alter the age of any living thing. When doing so, that living thing's memories will remain intact and their clothes will alter their size to fit them. Occasionally, the object will continue aging/de-aging for a certain amount of time.
 * Titanio (portrayed by Chris Elwood) was a test pilot turned aero space engineer who is also a billionaire. He became Titanio to battle the forces of evil. He has no powers, but he has a robotic suit with a stun ray, a jet pack, and strength boosters like Iron Man. He appeared in "I, Normo" where he had amnesia courtesy of the Black Falcon. With Alan's help, he regained his memory, but mistook Alan for the real Black Falcon and gave him amnesia. With his full suit on, he resembles Optimus Prime from Transformers. In "Guitar Superhero", Skylar enlists Titanio to pose as Soul Slayer to fight Remix while his robotic suit was being repaired. In "Free Wi-Fi", Titanio's robotic suit is possessed by Wi-Fi.
 * Mesmera (portrayed by Tiphani Abney) is a female superhero who has an eye on the palm of her right hand that can hypnotize anyone. In "I, Normo", Alan used Mesmera in an attempt to restore Titanio's memory.
 * Citadel is a superhero with indestructible skin that can deflect magnetic fields. Citadel first appeared in "Sm'oliver's Travels", where he had stomach pains. Due to his indestructible skin, surgery could not be performed on him, so Oliver was shrunken and sent inside his body to remove the source of the pain. He reappears in "The Friend of My Friend Is My Enemy" where Oliver used an advanced stethoscope to hear his heartbeat.
 * The Great Defender (portrayed by Dwight Howard) is from another planet, like Skylar. His suit is indestructible and his powers consist of ice ball projection, superhuman strength, and spinning things at high speed on his fingertips like a basketball. Despite being six feet and 11 inches, he is the shortest person on his planet. He appeared in "Pranks for Nothing", where Kaz played a prank on him by super-gluing a coin to the floor. He later tricked Kaz and Oliver into thinking he spun the Earth on his finger and pretended that his powers weren't working. He then had Solar Flare heat up the hospital to make them think the Earth was hurling towards the sun and had Horace make them think they had to sacrifice themselves to save the Earth. He was mentioned by Alan in "Alan's Reign of Terror" where Alan had him slow down the rotation of a planet so that his uncle's appointment there would be longer.
 * Captain Atomic (portrayed by Bradley Dodds) was hit by a radioactive bullet in the 1950s, but survived thanks to the lucky yo-yo given to him by his girlfriend. Captain Atomic has the power of flight and can infuse atomic power into his yo-yo, allowing him to use it to snare his enemies, use it as a shield, and use it as a whip. He attempted to stop an intergalactic war in 1953, but a mishap trapped him in a wormhole for 61 years. In the present, the wormhole was opened by Oliver. After he was given a new battery to help him survive and defeating the Black Falcon, Captain Atomic decided to stick around in the present and experience its wonders. In "Fantasy League of Superheroes", it is revealed that Captain Atomic has super-strength and near invulnerability to the point where it can rival with Tecton's abilities.

He appeared in "It's Not the End of the World", where he came to Mighty Med because his powers were acting up. He helped Kaz ace his pop quiz, but because Kaz became smart, it was one of the requirements to open a portal where Crimson Demon's brothers Blue Demon, White Demon, and Matt Demon, were which almost ended the world. He speaks with an Italian accent. Due to him being played by the same actor as his cousin, they cannot appear on screen at the same time.
 * Gray Granite (portrayed by Mike O'Hearn) is a rock-based superhero who was first seen in "Evil Gus".

 * Neocortex (portrayed by Mike Bradecich) is a telepathic superhero that can communicate mentally, alter one's personality, link minds, and put people into dreams and nightmares. Neocortex also has neuron-manipulation, which means he can send out psychic bursts that can immobilize a villain or control their behavior. He first appeared in "All That Kaz", where he broke his shoulder surfing the Internet. Oliver, wanting to be more popular, had Neocortex alter his personality to be more like Kaz's, but the real Kaz wanted to change it back. Unfortunately, Oliver redirected the blast back at Neocortex, causing him to become a nuclear reactor that almost blew him and the hospital up. Oliver cured Neocortex and Neocortex gave Oliver his original personality back. He reappears in "Night of the Living Nightmare", where he holds a grudge against Oliver for the events of his previous appearance. During that time, there was a lunar eclipse that caused him to only give people nightmares and if the victim dies in their nightmare, they'll die in reality. Luckily, the lunar eclipse ended before anyone died. In "Mighty Mole", Skylar uses the Annihilator's formula to turn him evil alongside Blue Tornado.

Later she was attacked by her nemesis and left in critical condition. She was taken to Mighty Med, but without her powers to save her, she would die. As such in "Lair, Lair", Kaz and Oliver went to get them back from the Annihilator's lair. At the end, her powers were restored and she happily created snow balls to celebrate. However, Skylar had secretly injected the Annihilator's secret formula into them meaning that she turned evil and became another of the Annihilator's servants.
 * Jade (portrayed by Debby Ryan) was once an average, self-centered rock star who first appeared in "Guitar Superhero". During one of her concerts, Jade was covered with yak's milk lotion irradiated by sunlight. When she strummed her guitar with her tongue, the electric shock caused the lotion to give her flight, energy projection, and force field projection.

After Alan leaves, Horace is also shown to be covering up Optimo's secret. In "Do You Want to Build a Lava Man?" Optimo visits Horace for a medical procedure, causing Horace to keep Optimo from officially meeting Alan. Optimo's reason for having Horace watch Alan is to keep his archenemy, Razorclaw, from targeting Alan. The condition that Optimo has is a virus that would turn him into goo, and the only way to cure Optimo is to obtain a sample of Alan's DNA. When Horace manages to get a sample of Alan's DNA, he uses it to save Optimo before the final stage of the virus can turn him into goo. After being cured, Optimo is asked by Horace to obtain him a new paddle ball since the one he has is broken. In "The Mother of All Villains", Optimo in the form of Nelson attended the wedding of Horace and Bridget.

Because of this, Spark knew that Kaz wasn't the right type of person to go out with.

Supervillains

 * The Annihilator (portrayed by Morgan Benoit and voiced by David Sobolov) is a fully armored supervillain who is the main archenemy of Skylar, Kaz and Oliver. He was once an original human named Neil Gundenhauser who developed superpowers and was tormented and teased for being a freak.

In a twist ending, the Annihilator had tampered with Skylar's powers in order to control her and Mighty Med. In "How the Mighty Med Have Fallen", the Annihilator plans to obtain the quantum chip that contains the secret files of every superhero. It turned out that the quantum chip is in the form of a sour cream and onion potato chip that Kaz and Oliver ate, which the Annihilator and Skylar plan to get it out of their stomachs.

Upon forcing the location of Mighty Med out of Alan and leaving him bound and gagged, Wallace and Clyde rejoin Horace's piece of the dyad with theirs at Mighty Med's entrance and joined together as Catastrophe to seek revenge on Horace. When he finds Horace, Catastrophe gets out of Horace's freeze trap and destroys the weapon that Horace would use in the event of Catastrophe's attack. Due to the reactor going nova, Catastrophe's powers were disabled as Alan breaks the dyad in half, regressing Catastrophe back to Wallace and Clyde. When Wallace and Clyde try to persuade Alan use the dyad's powers to become more powerful than he ever wanted to be and to give Wallace and Clyde a continent to rule over, as long as it's not Australia, Alan throws the Dyad of Nebulon pieces into the reactor, stating that it's too much work.
