Mighty Morphin Power Rangers

Mighty Morphin Power Rangers (MMPR) is an American superhero television series that premiered on August 28, 1993, on the Fox Kids programming block. It is the first entry of the Power Rangers franchise, and became a 1990s pop culture phenomenon along with a large line of toys, action figures, and other merchandise. The show adapted stock footage from the Japanese TV series Kyōryū Sentai Zyuranger (1992–1993), which was the 16th installment of Toei's Super Sentai franchise. The second and third seasons of the show drew elements and stock footage from Gosei Sentai Dairanger and Ninja Sentai Kakuranger, respectively, though the Zyuranger costumes were still used for the lead cast in these two seasons. Only the mecha and the Kiba Ranger (White Ranger) costume from Dairanger were featured in the second season while only the Kakuranger mecha was featured in the third season, though the Kakuranger costumes were later used for the mini-series Mighty Morphin Alien Rangers. The series was produced by MMPR Productions and distributed by Saban Entertainment, while the show's merchandise was produced and distributed by Bandai Entertainment.

While a global storyline would continue in Power Rangers Zeo, Power Rangers Turbo, Power Rangers in Space, and Power Rangers Lost Galaxy (which could be considered respectively and unofficially as the fourth, fifth, sixth, and seventh seasons of the original series), the subsequent series would not be sequels or spin-offs in the traditional sense, having self-contained plots with no strong connection with the original series (except taking place in the same universe, not being reboots). The exceptions would be Power Rangers Dino Thunder, which could be considered as a continuation of the original classic series by having the presence of the character Tommy Oliver (the Green Ranger and later White Ranger, portrayed by Jason David Frank) as part of the regular team of Rangers of the generation of that series (in some of the other series the character only made special participations). Another series connected to the original classic series would be Power Rangers Operation Overdrive, as one of the main villains of this series, Thrax, is the son of Rita Repulsa and Lord Zedd, main villains of the classic series.

In 2010, a remake of Mighty Morphin Power Rangers, with a revised new look of the original 1993 logo, comic book-referenced graphics, and extra alternative visual effects, was broadcast on ABC Kids, and Bandai produced brand new toys to coincide with the series. Only the first 32 of season one's 60 episodes were remade. It was the final Power Rangers season to air on ABC Kids as Haim Saban re-acquired the franchise from Disney, who took over the rights in 2002. With the beginning of Power Rangers Samurai in 2011, the franchise had moved to Nickelodeon.

The original series also spawned the feature film Mighty Morphin Power Rangers: The Movie, released by 20th Century Fox on June 30, 1995. Despite mixed reviews, it was a success at the box office, and earned a cult following. In 1997, a second film titled Turbo: A Power Rangers Movie was released as a bridge between the series Power Rangers Zeo and Power Rangers Turbo. In 2017, a reboot film based on the original series was distributed by Lionsgate, simply titled Power Rangers. Due to both the film's financial failure and Hasbro's acquisition of the franchise in 2018, another reboot is in development.

A television special titled Mighty Morphin Power Rangers: Once & Always commemorated the 30th anniversary of Mighty Morphin Power Rangers and premiered on Netflix on April 19, 2023, with returning cast members David Yost, Walter Emanuel Jones, Steve Cardenas, Johnny Yong Bosch, Karan Ashley, Catherine Sutherland, Barbara Goodson, and Richard Steven Horvitz who reprised their roles. Charlie Kersh portrayed Minh, the daughter of Trini Kwan and the third Yellow Ranger.

Season 1 (1993–1994)
The series takes place in the fictional town of Angel Grove, California. On an exploratory mission on the moon, two astronauts discover an extraterrestrial container (referred to as a dumpster) and breach the unit, inadvertently releasing the evil alien sorceress Rita Repulsa and her minions from 10,000 years of confinement. Upon her release, she and her army of evil space aliens set their sights on conquering the nearest planet—Earth. The wise sage Zordon, who was responsible for capturing Rita, later becomes aware of her release and orders his robotic assistant Alpha 5 to select five "teenagers with attitude" to defend the Earth from Rita's attacks. The five teens chosen are Jason Lee Scott, Kimberly Hart, Zack Taylor, Trini Kwan, and Billy Cranston. Zordon gives them the ability to transform into a superhuman fighting force known as the Power Rangers. This provides them with formidable abilities and an arsenal of weapons, as well as colossal assault vehicles called Zords which can combine into a giant humanoid robot known as the Megazord.

The series begins with the five teenagers combating Rita and her seemingly endless array of monsters, while also dealing with typical teenage problems and clashing with local bullies Bulk and Skull. However, consecutive failures lead Rita to adopt a new method for conquering Earth and destroying the Power Rangers—by attacking them with one of their own. Using her magic, Rita kidnaps and brainwashes a local teen whose fighting skills prove to equal that of Jason's in a martial-arts tournament held in Angel Grove. The new teen, Tommy Oliver, passes Rita's tests, becoming the Green Ranger. Entrusted with Rita's Sword of Darkness, the source for the continuance of the evil spell he has fallen victim to, Tommy comes dangerously close to defeating the Power Rangers. After sabotaging the Command Center and cutting off Zordon's connection to their dimension, Tommy helps Rita strike another blow to the Rangers when the Megazord is drained of its power in battle by a solar eclipse and then blasted into a molten lava crevice. However, Alpha eventually succeeds in reestablishing connection with Zordon, who then revives the Megazord. With it, the Rangers stop Tommy's rampage on Angel Grove with his Dragonzord, and Jason ultimately defeats Tommy in a one-on-one duel by destroying the Sword of Darkness. Now free from Rita's spell, Tommy chooses to use his Green Ranger powers to assist the Rangers in defeating the evil that gave them to him in the first place, and the Dragonzord is reconfigured to enable it to help form more powerful Zord combinations alongside the other Dinozords.

As time goes on, Rita focuses on eliminating Tommy to regain the powers that she believes belong to her. Using a special wax that was touched by Tommy when he was evil, Rita uses a magic Green Candle to slowly remove his powers, returning them to her. In the end, Tommy loses his powers, but he prevents Rita from reclaiming them by transferring them to Jason who, feeling guilt for failing to protect Tommy's powers, accepts them. However, Tommy later returns to the team when the other Rangers' Power Coins are handed over to Rita in exchange for their kidnapped parents. With Zordon's help, Tommy regains his powers and successfully retrieves the other Rangers' Power Coins. However, Tommy's regained powers are only temporary and must be frequently re-charged by Zordon, who warns him that the Green Ranger's powers will ultimately fail. Despite this, Tommy remains determined to continue assisting the other Rangers as long as possible.

Season 2 (1994–1995)
Lord Zedd, an intergalactic warlord and Rita's superior, arrives at Rita's Moon Palace, where he takes her place and throws her into a space dumpster again. He then begins his own campaign to conquer Earth. In order for the Power Rangers to compete with Zedd's monsters, which are superior to the ones Finster made by Rita, Zordon and Alpha upgrade the Dinozords into the more powerful Thunderzords (which combine into the Thunder Megazord). However, Tommy is forced to retain use of the Dragonzord, due to his Green Ranger powers being too weak to support a new Zord.

After several defeats, Zedd's attacks on the Rangers progressively become more violent. He focuses his attention on eliminating Tommy, whom he sees as Rita's biggest mistake in giving him the Dragon Power Coin. The Green Ranger's powers were rapidly deteriorating, but Zedd's efforts had enhanced the process. He eventually does so with a special Green Crystal, using it to take away the Green Ranger's powers. The crystal also powers up Zedd's Dark Rangers, but when Tommy smashes it, the Dark Rangers are sent away. Nevertheless, Zedd finally succeeds in taking the Green Ranger's powers (which Rita later uses to power Tommy's clone to battle against the Rangers before reclaiming it once more). Following the loss of the Green Ranger's powers, Zordon and Alpha create, in secret, a new White Ranger to aid the other Rangers in battle. The White Ranger is revealed to be Tommy, who in addition receives a new Zord, the Tigerzord, and also becomes the new leader of the Power Rangers (replacing Jason), with a power that cannot be controlled or taken by the forces of evil.

During the Team Ninja Trials in Angel Grove, the Rangers become friends with three teenagers from Stone Canyon: Rocky DeSantos, Adam Park and Aisha Campbell. During an ensuing battle with Zedd and a magical serpent, Rocky, Adam and Aisha discover the Rangers' identities and, having been entrusted with their secret by Zordon, the three newcomers become allies of the Rangers.

Later on, Jason, Zack and Trini are selected to represent Angel Grove at the World Peace Conference in Geneva, Switzerland, and the Rangers are faced with the task of finding replacements. To transfer the powers of the Red, Black and Yellow Rangers, they must find the Sword of Light, which is located on a Deserted Planet. Zedd pursues them across the galaxy in Serpentera, his massive personal Zord, and destroys most of the Deserted Planet. Serpentera runs out of power before being able to finish the Rangers, and they return to Earth safely with the Sword of Light. Zordon then chooses Rocky, Adam and Aisha to replace Jason, Zack and Trini as the Red, Black and Yellow Rangers, respectively.

Sometime before the power transfer, during the time when Tommy was being turned into the white ranger, Rita had returned to Earth and fell into the hands of Bulk and Skull, but the Rangers sent her back into space. She later returns to the Moon while the Rangers are in Australia, and with the help of Finster, she gets a special "makeover" to gain a younger and "prettier" face. She then uses a love potion on Zedd, who is in a deep sleep during his centennial re-evilizer, and he falls in love with her when he wakes up. They get married and join forces to make an even more terrible threat for the Rangers, but not even this can prepare them for what is to come.

Season 3 (1995)
Rito Revolto, Rita's skeletal brother, comes to Earth and with the help of a group of monsters, destroys the Rangers' Thunderzords and the Tigerzord. As a result, the Dinozords are also destroyed and the Power Coins are damaged beyond repair. Undaunted, the Power Rangers seek the aid of Ninjor, alleged creator of the Power Coins, who gives them new Ninja Coins, providing them with the even more powerful Ninjazords (which combine into the Ninja Megazord) and the Falconzord.

An Australian girl named Katherine Hillard moves to Angel Grove. She befriends the rangers and displays an intense affection for Tommy. Later it is found out that Rita had captured Katherine and put her under a powerful spell, giving her the ability to transform into a cat as well as a cat-like monster. Under this spell, she steals Kimberly's Ninja power Coin, vastly weakening and nearly killing the Pink Ranger, whose life force, like that of the other Rangers, is connected to her Ninja Coin. It is during this time that the Rangers acquire their most powerful Zords: the Shogunzords (which combine into the Shogun Megazord). Eventually, Katherine overcomes Rita's evil spell and returns the Pink Ninja power Coin to Kimberly. A short time after, Kimberly gets a chance to pursue her personal athletic dreams. With Zordon's blessing, she leaves to train for the Pan Global Games, choosing Katherine to replace her as the Pink Ranger. Though her initial fear and hesitation keeps her from contributing fully to the fight against evil, Katherine eventually becomes both comfortable and capable of fulfilling her duty as the second Pink Ranger.

After several more battles, Zedd and Rita are joined by Rita's father, Master Vile. Following his failed attempts to defeat the Rangers, he reverses time, turning the Rangers into powerless children. These events culminate in the mini-series Mighty Morphin Alien Rangers and lead to the next incarnation of the franchise, entitled Power Rangers Zeo.

The golem warriors made of clay who act as Rita Repulsa's foot soldiers, the Putties are often sent to wear the Rangers down before a monster battle, as well as for sabotage and other special missions. The original Puttys were based on Golem Soldiers, which were the Sentai Counterpart on Zyuranger. In Season 2, Lord Zedd upgrades the Putty design, completely replacing Rita's original design. Zedd's Putties (or Z-Putties for short) are superior to the original Putties and are more expendable. However, the Z-Putties also have a big weakness—striking the Z-logo on their chests causes the Z-Putties to explode into pieces. The Z-Putties were the first group of Power Ranger exclusive foot soldiers. The crow-like soldiers that are able to speak. They are introduced in Season 3 when Rito takes them with him to the Moon as a wedding gift, and replace Zedd's Putties. The Rangers normally use their Ninja Ranger powers to fight them. Unlike the Putties, the Tenga Warriors are not expendable and they return to the Moon when defeated. The Tengas originated in Mighty Morphin Power Rangers: The Movie (going by the name "Tengu Warriors") under the command of Ivan Ooze. The name changed between the movie and show was because of copyright complications with the movie's producer 20th Century Fox.. Like the Z-Putties, the Tenga's were the second group of foot soldiers exclusive to Power Rangers.

Conception
While on a business trip to Japan, Haim Saban came across a broadcast of Choudenshi Bioman on TV Asahi, later learning of a popular French-language dub aired on Canal+. Based on the franchise's popularity both in and outside of its native country, Saban realized there was potential for an American adaptation. He and his business partner Shuki Levy quickly produced a pilot entitled Bio-Man in August 1986, which featured an early appearance by actor and martial artist Mark Dacascos in a leading role. According to Levy, they "shopped it around for at least five years, but nobody wanted it." Saban only found success in 1992, when he found a network executive familiar with Super Sentai, Fox Kids' Margaret Loesch, that during her time with Marvel Productions saw partner Stan Lee trying to sell the Sun Vulcan series to various television stations such as ABC, CBS, NBC, and HBO. Loesch's boss at Fox did not have much faith in the project, only financing a pilot that if unsuccessful, could even lead to Loesch's dismissal. Levy and Saban then began working on the pilot using footage from the latest Sentai season, Kyōryū Sentai Zyuranger, entitling the pitch Galaxy Rangers. A test screening with an audience of children was successful, and eventually, the pilot was picked up by Fox Kids for a 40-episode order, after which point it would be determined by the network whether or not to renew the series for additional episodes.

Casting
Due to the action-oriented nature of the show, many of the lead actors cast had background in martial arts, dance, or other physically intensive activities. Amy Jo Johnson (Kimberly) and David Yost (Billy) were former competitive gymnasts,  Austin St. John (Jason) held a second-degree black belt in Taekwondo, and a first-degree black belt in Judo. Walter Emanuel Jones (Zack) was a dancer and trained in Taekwondo, and Thuy Trang (Trini) was a kung fu practitioner. Actor Jason Narvy (Skull) originally auditioned for the role of Billy.

Filming
The series was shot on location in Santa Clarita and Los Angeles, California. Recurring locations included Grant High School, Placerita Canyon State Park, Puddingstone Reservoir, and Frank G. Bonelli Regional Park. The House of the Book at Brandeis-Bardin Institute was used as the exterior location for the Command Center. Due to its unusual, futuristic architecture; the building had previously been used in the films Star Trek VI: The Undiscovered Country and The Lawnmower Man.

As part of the initial licensing agreement between Saban and Toei Company, the producers of the Super Sentai, additional footage was filmed in the Greater Tokyo Area in Japan, and insert shots of the villain characters (particularly those played by Machiko Soga, Ami Kawai, and Hideaki Kusaka) were filmed in order to allow more in-depth, extensive scenes of the villains who would be unable to interact with the main cast due to the nature of the show. The additional footage included close-ups of the actor speaking English-language lines phonetically in order to make the necessary dialogue looping more seamless.

Episodes 39 & 40 (The two part episode Doomsday) were originally intended as the season (and potentially series) finale. According to Paul Schrier, the producers brought Machiko Soga in to film new footage, but she could not mouth the dialogue. Due to the unprecedented success of the show and its merchandising, Fox Kids ordered an additional 20 episodes. Since most of the available stock footage from Zyuranger had been depleted for use in the first 40 episodes of Season 1, Saban commissioned Toei to produce 25 new monster costumes and new battle footage using the existing Zyuranger suits. This new footage has been referred to as "Zyu2" by Power Rangers fans. Saban used 15 of the new monster costumes and their footage for the rest of Season 1 (episodes 41–60), then the remaining ten for the first 13 episodes of Season 2. This became problematic, however, when the Thunderzords were introduced, as they were from Gosei Sentai Dairanger, which resulted in Saban splicing together footage from both "Zyu2" and Dairanger for the Megazord battles in these early Season 2 episodes.

Following production of Season 2's first 20 episodes, Austin St. John, Thuy Trang and Walter Emanuel Jones left the show over contract disputes. To disguise this incident, a combination of body doubles, voice doubles and stock footage were used to continue featuring the characters Jason, Trini and Zack for eight episodes. The voice doubles were also used for the Ranger costume scenes in the last several episodes that the three actors filmed. The subplot of Jason, Trini and Zack leaving Angel Grove for the World Peace Conference was made to bridge the transition to their replacements.

During the later portion of Season 2 (following Rocky, Adam and Aisha's introduction to the series), the production moved to Sydney, Australia for roughly four months to shoot Mighty Morphin Power Rangers: The Movie, which was released the following summer before the start of Season 3.

Depictions of violence
Despite the success of the series, it was also subject to much controversy from parents who felt the show was too violent for young children. The show had aired before television stations issued content warnings such as parental guidance or fit for viewing persons twelve years or over, the V-chip, and television ratings. In the US, numerous complaints were sent to the Federal Communications Commission (FCC). In 1993, the Canadian broadcast rights to Mighty Morphin Power Rangers were jointly purchased by the YTV cable channel, and the series played to a receptive audience every weekday afternoon on YTV, the latter trailing the American broadcast by several months. However, due to complaints sent to the recently formed Canadian Broadcast Standards Council and a negative assessment from that body over the show's violent content, YTV removed the series from their line-up in November. Despite not actually being a member of the CBSC, YTV complied and pulled the series before the end of its first season; Global (which was a CBSC member) ultimately did the same. While a phone-in poll was conducted to see if viewers wanted MMPR back on YTV, no further installments of the Power Rangers franchise aired on the network until 2011's Power Rangers Samurai, although commercials for toys and videos were still advertised on it. Later Disney-era versions of the series were broadcast on ABC Family.

In 1994, the New Zealand Broadcasting Standards Authority (BSA) upheld several complaints from members of the public about the level of violence in the show. The main concern of those complainants was that the show portrayed violence as the primary means of resolving conflict, and that this was influencing children to behave more violently more frequently. Immediately following the BSA decision, the second season of the show was all but cancelled by Television New Zealand. New Zealand is the only country in the world where this show has been prematurely withdrawn from public broadcast to date. DVD and video releases of the more-recent Power Rangers series that were filmed in New Zealand can be found at The Warehouse, although general sales through video stores and other retailers are scarce. Later series in the Power Rangers franchise, such as Power Rangers: Mystic Force and Power Rangers: Jungle Fury, were filmed in New Zealand, but the programs were still not shown in the country, until 2011, when Samurai premiered.

In mid-October 1994, the murder of Silje Redergård by two of her young friends prompted Swedish-owned TV3 to pull MMPR from its broadcast schedule in all of its market countries. However, MMPR was not related to the event.

Poor work conditions
As a non-union production, members of the original cast were reportedly subject to low pay, long hours, unfair contracts, and a hostile work environment and, as many of the cast were young, aspiring actors, they had no agents or lawyers to protect their interests and they themselves had limited experience in the entertainment industry. Additionally, despite the show's financial success, members of the original cast did not receive royalty payments for re-runs of episodes in which they starred.

Austin St. John, Thuy Trang and Walter Emmanuel Jones were the first to leave the series, citing low pay, in the middle of the second season, and St. John was homeless for a time after leaving. While the reasons for their departure was debated for many years, St. John would confirm in 2014 that the departure was due to the low salaries the stars were being paid; he stated "I could have worked the window at McDonald's and probably made the same money the first season. It was disappointing, it was frustrating, it made a lot of us angry." The actors were receiving non-union pay, in the amount of about $60,000 per year without any compensation for merchandising for the show, which was estimated to be worth about $1 billion. Trang, St. John, and Jones were all represented by agent Ingrid Wang, and they requested more compensation and union recognition. Amy Jo Johnson, who left the series in the middle of the third season, later expressed regret that she and the other cast members did not join the three departing cast members in calling for union wages and recognition, wondering if all of them standing together may have led to a different result. According to Johnson, St. John, Jones and Trang had wanted the show to become unionized, leading to them being replaced by Steve Cardenas, Johnny Yong Bosch, and Karan Ashley, respectively.

Within the show, the actors' departure was explained by their characters being chosen as representatives in an international "Peace Conference" in Switzerland. Trang, St. John, and Jones released a joint statement about their departure:

After two seasons as the Power Rangers, we would now like to move forward to the many new opportunities that have been presented to us. Our Power Rangers experience will always remain an exciting and important part of our lives and careers, and it is gratifying that through our participation in the show, we were able to touch the lives of so many young people.

Allegations of homophobia
David Yost was the last of the original Ranger actors to leave the series (during Power Rangers Zeo), citing homophobic attitudes from production staff, prompting him to unsuccessfully undergo conversion therapy in an effort to change his sexuality. In a 2010 interview with fan blog "No Pink Spandex", Yost stated that he walked off set one day because "[he] was called 'faggot' one too many times." He also stated that the producers would often ask other cast members what they thought about his homosexuality, and this made him uncomfortable as well. Shortly after this interview, producer Scott Page-Pagter stated that Yost left over a pay dispute and that he didn't know why Yost made the allegations of homophobia; he further stated that Yost did not get along with any of the crew.

Other
In Malaysia, the phrase "Mighty Morphin" was censored and edited out from the logo due to the word "morphin" being too similar to the name of the drug morphine.

Broadcast and home media
Reruns of Mighty Morphin Power Rangers were aired on all networks such as Fox/ABC Family, Toon Disney (part of the Jetix block) and ABC Kids for a short time, but returned on TeenNick's The '90s Are All That block in honor of the series' 20th anniversary in 2013 and later in 2023, Video on Demand network Kabillion currently airs the show.
