Super Sentai and its adaptation Power Rangers are no strangers to the Evil Knockoff trope; Almost every series has an episode in which the Big Bad creates bad Rangers.
- The very first evil ranger that wasn't a duplicated or brainwashed preexisting ranger showed up in Choudenshi Bioman when the villains tricked a man who wanted to become the sixth Bioman into letting them turn him into an evil ranger called Magne Senshi. He was freed a from the villain's control in the same episode and didn't keep his powers.
- Mighty Morphin' Power Rangers did this a few times:
- The most memorable instance of this trope is Rita Repulsa turning Tommy Oliver into her own evil Green Ranger, who nearly defeated the Power Rangers, but had a Heel–Face Turn and became the Trope Codifier and Trope Namer to the Sixth Ranger trope. His counterpart in Kyōryū Sentai Zyuranger, Burai/DragonRanger, averts this trope since his powers weren't created by Rita's counterpart, Bandora.
- Two of Rita's plans featured her turning a few of her Mooks into an evil team of Rangers who were defeated within the same episode.
- Lord Zedd created his own team of Dark Rangers from a gang of nasty bullies. Their suits looked so bad, they actually resembled knockoffs.
- In "Return of the Green Ranger" White Ranger Tommy was cloned and the clone became the Green Ranger.
- In Blue Ranger Gone Bad, the villains turn a statue of Billy into an evil clone, including the ability to morph.
- Subverted in Denji Sentai Megaranger. Near the end of the series, the villains create a team of evil rangers, the Jaden Sentai Nejiranger. But the suits these rangers wear are actually the prototypes to the Megarangers' suits. Power Rangers in Space plays this trope straight, by featuring the Trope Namer to The Psycho Rangers trope.
- The Cyborg Rangers from Power Rangers Lightspeed Rescue subvert this trope. They are mechanical copies of the rangers with all of their powers and weapons, but aren't created by the villains to destroy them. Rather, they are created by the government to replace the rangers as they think robots are more efficient than humans. But the Cyborg Rangers short circuit and start attacking , forcing the actual rangers to destroy them.
- Power Rangers: Dino Thunder had an evil knockoff of the White Ranger after the original evil one did a Heel–Face Turn. Interesting to note is that the white ranger of Dino Thunder's source material, Bakuryuu Sentai Abaranger, was an evil ranger for the majority of the series. The evil knockoff in Power Rangers was actually a way to utilize the footage of the White Ranger fighting against the others, despite already having his Heel–Face Turn.
- Exclusive to Jungle Fury are the Spirit Rangers, senior members of the Rangers' order, with original suits and attacks based on the masters' own animal spirits. Naturally, the masters are freed from Brainwashing and the baddies now have eight rangers to deal with.
- The villains in Dobutsu Sentai Zyuohger create their own evil ranger named The World. The main team of rangers consist of four beastmen who draw power from their own animal halves and one human who got his powers by having a beastman voluntarily transfer his powers to him. The evil ranger is created by forcibly transferring the souls of three beastmen into one human, but is later freed from their brainwashing and becomes the Zyuohgers' Sixth Ranger, Zyuoh The World.
- Mashin Sentai Kiramager has the Yodon Changer, a recolored version of Kiramai Silver's Shiny Kiramai Changer that he used to transform while he was briefly brainwashed by Galza. The Yodon Changer would later be used by Yodonna, albeit mostly for communicating with Emperor Yodon instead.
- Kikai Sentai Zenkaiger: One of the main villains is an evil ranger called Staceasar that looks like a purple version of Zenkaizer, except with with scarf and a helmet similar to Battle Japan instead of Akarenger. He's able to summon evil copies of previous Sentai Rangers under his command, and at one episode pilots a knockoff of the Zenkaigers' Humongous Mecha ZenkaiOh
- Avataro Sentai Donbrothers has Don Murasame, who like Stacaesar looks like a purple-colored version of the main Ranger.
- The Mechas are no strangers to this trope either. Starting from Zenkaiger, it became common for each show to feature an evil recolor of the Rangers' main robo that is created by the villains:
- The Summer Movie of Kaizoku Sentai Gokaiger predates this with a Fake GokaiOh Piloted by Los Dark, the Big Bad of the movie.
- Zenkaiger has ZenkaiOh Black JuraGaon, piloted by the aforementioned Stacaesar, but said Mecha only lasted two episodes, with Stacaesar usually piloting the Battle Caesar Robos instead.
- Avataro Sentai Donbrothers has Black Onitaijin Murasame (Don Murasame's transformed form).
- Ohsama Sentai King-Ohger has King-Ohger ZERO, an artificial version of King-Ohger (Piloted by OhKuwagata Ohger).
- Bakuage Sentai Boonboomger has the Boonboom Killer Robo, a rust colored retool of Boonboomger Robo (Piloted by the Sanseaters). It later gets mass produced by a Corrupt Corporate Executive who wants to sell these to facilitate War for Fun and Profit.
- No.1 Sentai Gozyuger has Queen TegaJune, but unlike most of the previous examples she's actually a living being and the Big Bad of the series, being a robotic copy of the Gozyugers' TegaSword (also a living being and the Gozyugers' mentor figure) created by humans in his image.
