The trope namer are the Psycho Rangers from Power Rangers in Space, a group of evil Rangers that fought against the Space Rangers during the course of the series, and returned in Power Rangers Lost Galaxy (most notably Psycho Pink, whose actions led to the Pink Galaxy Ranger being killed off and replaced). Their counterparts in Denji Sentai Megaranger were the Jaden Sentai Nejiranger.
Super Sentai and Power Rangers are both fond of this very trope. More often than not the evil counterparts are usually one-off clones created by the villains that are quickly disposed by the end of the episode, but a few shows have actually featured their own recurring evil Ranger team to antagonize the heroes.
The "Ginga Sentai Gingaman" (not to be confused with the later heroic Seijuu Sentai Gingaman) from Chikyuu Sentai Fiveman were the first truly recurring Evil Sentai within the franchise. They were evil space aliens who, at first, attempted to gain the trust of Earthlings by pretending to be heroes, but eventually they turned out to be villains.
The Dark Rangers from the second season of Mighty Morphin' Power Rangers only appeared in the two-part episode "Green No More" and were exclusive to Power Rangers. They were classmates of the Power Rangers who were brainwashed to serve Lord Zedd, but they never actually fought their heroic counterparts since the costumes worn by the stuntmen, which were recolored Putty suits, were too delicate to withstand battle.
In the comic adaptation, we got a proper battle, with the real Rangers in the Ninja Ranger suits from season three and the bad guys in the old MMPR suits.
The Hana Kunoichi Gumi (the "Flower Kunoichi Gang", aka the Hanarangers) from Ninja Sentai Kakuranger were an all-female gang of ninjas who were actually stray cats that were transformed into women by Gasha Skull (Rito Revolto's Japanese counterpart). Unlike other evil Sentai teams, their colors were different from the good team and they were all female. You also almost never got a five-on-five battle.
Turbo exclusive Shadow Rangers were copies made from the true Rangers' powers, and as such the real Rangers couldn't morph. They had to be tricked into falling to their Kryptonite Factor by the only powered Ranger left. They may have been based on sentai's somewhat similar Shadow Jetmen.
Power Rangers Lightspeed Rescue had robotic replacements for the Rangers. They were referred to as cyborgs though there was no sign of them not being all machine. A monster turned 'em evil and they had to be dealt with. Not in sentai; closest counterpart is a new mecha that was driven evil by a different monster and had to be taken out.
Power Rangers Time Force had a monster suck the Rangers into a pocket dimension with bad Time Force Rangers. For the first time since the originals (which had to be indentical to smear the real Rangers) we don't have any tells that let you know which is which.note The Mutant Rangers still had Putty hands and feet and their weapons looked like non-Rangerized versions of the Rangers' weapons, the Shadow Rangers had de-colorized helmets, the Psycho Rangers were all-new designs, and the Cyborg Rangers had visible remote control receivers. They also lived up to being every bit as strong as the originals for once. They had to break the Monster of the Week's pocket dimension to get away from them. For all we know, evil Time Force Rangers still wander some forgotten zone of reality.
Power Rangers Wild Force has the Shadow Rangers, no relation to the Turbo ones. Onikage made them from the Rangers' shadows; any damage done to them was felt by the real ones. Gaoranger'' had these and also the Copy Rangers created by a Monster of the Week made from a copy machine.
The "Goraijer" in Ninpuu Sentai Hurricaneger (aka the Thunder Rangers in Power Rangers Ninja Storm) are played up as these to the male Hurricangers (Wind Rangers). In both cases, they're more Anti Heroes and soon ally with their more heroic counterparts (the Thunder Rangers fit in fairly seamlessly, but the Goraijers remained somewhat antagonistic)
The Ninja Storm episode "Wild Wipeout" deals with Tori being transported to a mirror universe a la Dorothy only via rogue wave instead of tornado. Said universe has the other five Rangers and Sensei being evil troublemakers and she's unable to take them all on alone. Fortunately, she's able to convince Lothor and his minions (who are good in this universe) to stand up to them before retuning to her own dimension.
Also in Dino Thunder, there was Trent's White Ranger clone that was created by one of the MOTW's just in time to take the real White Ranger's place when he turned good. He lasted for pretty much the rest of the season until Trent finally destroyed him.
The A-Squad from Power Rangers S.P.D. was the first truly recurring evil Ranger team exclusive to Power Rangers. In contrast to previous evil rangers, they were actually the predecessors of the main heroes before they turned evil. Ironically enough their helmets were recycled from Power Rangers in Space, with the Black Ranger's helmet being repainted into a green one.
Power Rangers Mystic Force had another pocket-dimension-with-bad-Rangers thing. They could be told from the real deal by the neck of the suits being black instead of white.
Gogo Sentai Boukenger parodied the concept of evil Sentai teams in one of their Super Sentai history lessons. The main villain Gaja decides to form the "Gaja Dengekitai", recolored Mooks with himself as "Big One". There was also a more standard group created by a particularly elite villain-of-the-week; like the Mystic Force / Magiranger version, the necks were black. As a silver-colored villain an enemy of the Sixth Ranger with a similar weapon, the creator of the bogus Rangers also doubled as Silver's counterpart.
Power Rangers Jungle Fury had the Spirit Rangers - the Rangers' masters brainwashed to fight the good guys. Turns out they were doing it by remote, with the Ranger forms being astral projections.
Kaizoku Sentai Gokaiger has Basco, able to create clones of any past Ranger via Ranger Keys; he has all the Sixth Ranger keys before Gokai Silver shows up. The final round with Basco has him steal the Gokai Galleon and use the Gokaigers' own keys.The Movie (one of 'em) also has all the Ranger Keys stolen by Himitsu Sentai GorangerBig Bad the Black Cross Fuhrer (now the Black Cross King.) The Gokaigers and Goseigers have to fight dupes of every other Ranger ever.
The Rude Noise are an evil Ninja Crow counterpart to the Pizza Cat's own Rescue Team. However they only actually took on their counterparts in one episode. In all their other appearances they directly took on the three main pizza cats.
There was also an early Monster of the Week in the episode 'Double Trouble for Princess Vi' who could morph into any of the three Pizza Cats and copy their weapons too. He was destroyed by Speedy before he could do anything clever or funny with that ability.
Blackbeard's Pirates in One Piece. Based on what we've seen here's how it goes:
Blackbeard: In many ways, he's a fully grown version of Luffy, but with completely opposite opinions. This can range from simple disagreements on food or drink to the best way to achieve a goal. Both stole their Devil Fruits: Blackbeard sought out a particular fruit while Luffy thought it was dessert.
Everything bounces off of Luffy. Everything sticks to Blackbeard.
Lafitte: Navigator of the Blackbeard Pirates, he used to be a law enforcement official of some sort, manically/maniacally cheerful, and is very stealthy given his ability to sneak into a high security government meeting unnoticed. Nami, navigator of the Straw Hat Pirates, is the adopted daughter of a Marine woman, has a more Tsunderish personality, and has spent the last eight years of her life as a sneak thief before joining Luffy.
Doc Q: A doctor like Chopper, but, of course, not so kind; he takes an active delight in foisting off apples on people that might well kill them in a gruesome fashion. Probably an excellent doctor when he needs to be, but doesn't seem to care about anybody besides his crewmates. His old age and guile also contrast with Chopper's youthful naivete.
Shiryu of the Rain, who makes a good counterpart for Zoro. He is also a swordsman and, much like Zoro in his role as Number Two, is the one who calls out Blackbeard after his recklessness nearly gets the rest of the crew killed. Blackbeard and Shiryu even met in a similar fashion, as the latter was on death row until Blackbeard came along.
In this case, it's still a little early to tell who's a counterpart of who. Especially now that the Blackbeard Pirates have doubled in size. One could easily argue that San Juan Wolf, the "Colossal Battleship", is the counterpart to the Thousand Sunny.
Wild child Kiba and his tiny ninja Angry Guard Dog Akamaru go up against sadistic The Dragon Sakonwhose secret weapon, his twin brother Ukon, lives in his body, making him bonus Creepy Twins as well, resulting in some rather literal Kick the Dog moments.
Then the series proceeds to set Sasuke himself up as Naruto's very own Psycho Ranger. Right up to the point where Naruto and his charming spiritual freeloader start to psycho back...
Sailor Moon had a set of these guys in most arcs/seasons (in order of appearance: The Shittenou, Ayakashi Sisters, Witches 5, Amazoness Quartet and Amazon Trio). Each of these groups was made up of colour-coded and power-coded evil counterparts of the Four Guardians (Ami, Rei, Makoto and Minako). In the manga, the Witches 5 were even resurrected just to kill the senshi they copied!
The Dark Kingdom Arc/Sailor Moon Classic: The Shittenou. Jaedite - Mars, Nephrite - Jupiter, Zoicite - Mercury, Kunzite - Venus.
Black Moon Arc/Sailor Moon R: The Ayakashi Sisters. Kooan - Mars, Berthier - Mercury, Petz - Jupiter, Calaveras - Venus.
Dream Arc/Sailor Moon SuperS: The Amazones Quartet. Ves Ves - Mars, Palla Palla - Mercury, Jun Jun - Jupiter, Cere Cere - Venus. In the manga, we find that they actually become Chibiusa's equivalent of the Four Guardians in Crystal Tokyo.
In the manga, the minor Quirky Miniboss Squad, the Amazon Trio, had counterparts; Fish's Eye - Mercury, Tiger's Eye - Mars and Hawk's Eye - Jupiter; whereas Venus was targeted by the Monster Clown duo Zeolite and Xenotime.
Weiss of Weiß Kreuz run into no less than three teams of Psycho Rangers, with increasingly closer resemblances to the series' four protagonists: Schreient, who qualified as Psycho Rangers mostly just by being a team of four assassins opposing the protagonists; Schwartz, who draw a more direct comparison ("Weiss" and "Schwartz" are German for "white" and "black"); and La Mort, the four villains of Dramatic Precious, all-out Psycho Rangers who started out as a previous incarnation of Weiss themselves only to be driven Ax-Crazy by the job.
Mewtwo's Pokemon clones from the first movie. The Venusaur, Charizard, Blastoise and Pikachu clones sport markings to distinguish them from the originals but the rest all look the same. It's subverted when Ash gets killed in the crossfire and their tears revive him. In fact the movie might count as a deconstruction of this trope.
In Katekyo Hitman Reborn!, this is explicitly the setup of the Varia arc. The seven Vongola Rings themselves are introduced as a device to set the hero's core "party" in stone (complete with specific character/elemental characteristics identified with each one)... and no sooner have they been introduced than the Varia shows up—a rival team aiming to usurp the heroes' position, with a matching party set up (one for each one of the Rings). The corresponding party members each then have to duel one another in a high-stakes Tournament Arc, predictably leading up to a final showdown between the two leaders. Specifically:
Boxer Ryouhei goes up against fellow martial-artist Lussuria with kicking battle style.
Lambo, whose immunity to lightning is revealed in this fight, faces fellow lightning-user Leviathan.
Bomber Gokudera is matched with fellow mid-to-long-range fighter Belphegor, who uses knives and wires.
They both also heavily abuse Hyperspace Arsenal, pulling out ridiculous amounts of knives/bombs from out of nowhere.
Swordsman Yamamoto has to face fellow swordsman Squalo.
Chrome Dokuro faces fellow illusion-user Mammon (as a bonus, both characters had been shrouded in mystery up until their fight).
Hibari faces Gola Mosca... but since Hibari's defining characteristic is being a complete Wild Card, the match is over in seconds, and he moves on to challenge the opposing team's leader without batting an eyelid; the leader chooses this moment to reveal that this was all part of his plan, and the entire tournament threatens to devolve into utter chaos.
Finally, Tsuna himself is, naturally, paired up against the opposing team's leader, both flame users and rightful heirs to the Vongola Family, in a match designed to showcase their leadership philosophies. Except that Xanxus is not a rightful heir, which is revealed when he won.
Xanaus didn't win, he utterly lost. He just had a backup plan in the event he did lose. Of course all his efforts were rendered moot when the rings rejected him.
Then they do it all again with the Real Six Funeral Wreaths, whose personalities and actions are complete opposites of the element they are supposed to represent.
Its happening for a third time with The Simon Family and their Rings/Flames of the Earth as opposed to the Vongola's Sky Rings/Flames.
Saiyuki has Affably Evil gang Kougaiji-ikkou to oppose Sanzou-ikkou, with the ring leader Kougaiji, the polite-but-deadly Yaone to Hakkai, the Badass Adorable Lirin to Goku, and the Big Guy Dokugakuji to Gojyo. They are all provided with solid backstory and personalities distinctive enough from the main characters to hold their own in the storyline. Both teams even work together on one occasion.
The Kougaiji-ikkou are almost a play on the trope, as they fit every criteria except being evil. For that matter, although Kougaiji is technically Sanzo's counterpart and Lirin is Goku's, it's Kougaiji and Goku who have the "Worthy Opponent" brawl whenever they meet, while Sanzo shoves food into Lirin's mouth until she shuts up.
The Shinigami captains vs the Espada in the Hueco Mundo arc of Bleach
Kenpachi vs. Nnoitra. The former just wants a good fight, and even gives himself handicaps so fights will last longer. The latter simply enjoys killing things and thinks nothing of using dirty tricks or attacking weakened opponents. Also, Kenpachi is considerably nicer to little girls.
Byakuya vs. Zommari. Both very skilled in shunpo/sonido, Byakuya's pride and devotion to the laws of Soul Society is mirrored by Zommari's zealous worship of Aizen. Zommari even tries to call Byakuya out on his flaws, saying he's only fighting because he believes Shinigami are inherently superior to Hollows. Byakuya then shows off his Character Development by saying he doesn't give a damn about the Shinigami/Hollow thing; Zommari tried to hurt his little sister, and that's more than enough reason to kill him.
Unohana vs. Rudbones. As captain of the 4th squad, Unohana's job is to find the wounded and heal them. As captain of the Exequitas, Rudbone's job is to find the wounded and kill them. Not to mention that Rudbones isn't actually strong enough to be an Espada, while Unohana is implied to be one of the strongest captains. The power gap makes it pretty obvious why they didn't actually fight.
The clones in the filler Invasion arc. They are stronger and more violent than the originals. And the filler Big Bad has cloned most of the captains. Fun times.
The tail end of the last episode of the first season of Galaxy Angel showed a team of evil counterparts to the Angels, one of whom was a spy that the real Angels just helped release. Unfortunately, this is all we ever see of them.
In Berserk, the "reborn" (for lack of a better term) Griffith creates a new Band of the Hawk (comprised mostly of Apostles like himself) that has counterparts to the group of friends formed by Anti-Hero Guts
Grunbeld is a massive warrior who wears similar armor and has an Arm Cannon like Guts
Irvine and Locus are BishounenNoble Demon characters who are obvious counterparts to two nobles (literally and figuratively) on Guts' side, Serpico and Roderick
New Band Of The Hawk seems to be made of evil counterparts to the members of original Band of The Hawk most of who are already dead.
In Blood+, The Corpse Corps are this for the Schiff. Despite undergoing similar treatment and brutal training, those of the Corpse Corps are emotionless, thoughtless, cold-blooded killers who will stop at nothing to achieve their goals as given by their masters. It is no wonder why Moses freaked out when he found out who were really behind their masks.
The Yes! Pretty Cure 5 movie features a Dark Cure team. In what is perhaps a bit of Genre Savviness, the first thing they do when they face the Pretty Cure team is to warp their counterparts off to different locations so they can't use the "switching opponents" trick.
The Garuru Platoon from Sgt. Frog. Giroro's counterpart is Garuru, Dororo's counterpart is Zoruru, Kururu's counterpart is Tororo, Tamama's counterpart is Taruru, and Keroro's counterpart is a child-aged clone of himself from before he met Fuyuki and Natsumi.
Eyeshield 21 had traces of this in both Shinryuuji amd Ojou. Hiruma, Unsui, amd Takami are all physically average quarterbacks who compensate with their dedication and intelligence, Kurita, Yamabushi, and Ootawara are all incredibly large noseguards who cry at the end of their games, Monta, Ikkyu, and Sakuraba are all recievers determined to be the best who have one area of specialty, and Sena, Agon, and Shin are the "aces" of their team.
Later on there was Clock King's Terror Titans, made up of original characters who used power suits and modeled themselves after older villains. As it turned out, none of them had any connections to the Teen Titans, except for Dreadbolt, who was the son of Bolt, a Blue Devil villain, making him a sort of rival to Kid Devil.
The truly bizarre thing is that this was a team of Psycho Rangers that never actually encountered their heroic counterparts, as they debuted after the death of the New Gods during Countdown and Final Crisis.
Most incarnations of the Masters of Evil in Marvel Comics are constructed in this manner.
The New Avengers arc of JMS' Spider-Man featured a team of evil Avenger doppelgangers working for HYDRA. Their costumes were basically green and yellow palette-swaps of the originals with the HYDRA octopus logo added on. "Militant" for Captain America, "Tactical Force" (though he prefers Karl) for Iron Man, "the Hammer" for Thor and "the Bowman" for Hawkeye. Spidey, of course, pointed out how done-to-death the evil twin thing was. None of them were captured, but they haven't shown up since then (except for the Facebook game, Marvel Avengers Alliance).
Legion of Super-Heroes has the Legion of Super Villains, which features some original villains, but in all incarnations features Lightning Lord, the older brother of Legionnaire Lightning Lad. The comic versions usually also feature Cosmic King and Saturn Queen, counterparts of Cosmic Boy and Saturn Girl, and, rarely, Chameleon Chief and Sun Emperor, counterparts of Chameleon Boy and Sun Boy. Micro Lad's shrinking complements both Shrinking Violet and Colossal Boy, and in the current series, Micro Lad is Colossal Boy, a giant who can shrink to six feet.
And taken even further with the reveal of new Lantern Corps. Mildly subverted in that while a few are obviously evil, a handful (Blue Lanterns, Indigo Tribe, even Star Sapphires) are friendly, or at least neutral to the Green Lanterns.
The DCUloves these. Lex Luthor's Injustice Society was made up entirely on one-for-one matches with the Justice League of the time.
Other examples include the Hyperclan, a band of so called heroes who are copies of the Justice Leagues core members, but they are in fact White Martians posing as heroes for their invasion.
The Black Marvel Family, Black Adam's equivalent to Captain Marvel's group of friends (even though Isis had a very different relationship with Adam than the one Mary Marvel has with Marvel) — although, while they existed, Black Adam was on a Heel-Face Turn, so they weren't Evil Counterparts so much as Dark Counterparts.
In Marvel Comics, the U-Foes are explicitly described as Psycho Rangers to the Fantastic Four, with identical origins (though not identical powers; the only one that comes close enough is Ironclad to the Thing), although they usually fight the Incredible Hulk.
The Frightful Four, despite its ever-changing roster, was created by the Wizard (a Mad Scientist Evil Counterpart to Reed Richards) to be Psycho Rangers to the Fantastic Four. For instance, one incarnation featured the Wizard (Mr. Fantastic), his friend the Trapster (the Thing), his ex-wife Salamandra (Invisible Woman), and someone unrelated to him who just happened to be Hydro-Man (the Human Torch). Eventually he forces his daughter Cole to join the group and throws out the Trapster to make room. Cole, who is a love interest to Johnny Storm, then takes up the Human Torch role while Hydro-Man fills the Thing space.
Carried to its ultimate extreme in Ultimate Fantastic Four, where the Frightful Four are the counterparts of the regular (read Ultimate, in this case) FF from another universe, just with about fifteen more years of experience. Oh yeah, and they're flesh-eating zombies.
In the Silver Age, DCU (again) introduced the alternate Earth of Earth-3, where the counterparts of the JLA were known as the Crime Syndicate. After massive retcons, there are two versions of this - the Crime Syndicate from the Antimatter Universe, and a new Earth-3 with the Crime Society, which are more like the JSA than the JLA.
Bizarrely, to this day there are neither Earth-3 nor Antimatter versions of the Martian Manhunter or Aquaman, or at least none that have ever been seen in comics. There have been brief mentions of 'a White Martian' and 'Barracuda', but that's as far as it goes.
The New 52's version of the Crime Syndicate introduced an evil Aquaman called Sea King. Also new to the group are Deathstorm (evil Firestorm), Atomica (evil Atom), and Grid (evil Cyborg).
The Shadowpact (DCU again) had the Pentacle, set up by a witch called Strega, which "just happened" to feature counterparts to the magical heroes. (Strega herself was the counterpart to the Enchantress; Jack of Fire to Blue Devil [and turned out to be his brother]; Sister Shadow to Nightshade; Bagman to Ragman; Karnevil to Detective Chimp (kinda); and White Rabbit to Nightmaster.)
However, in-universe the similarities were commented upon by Bagman, who noted that it felt as if this version of the Shadowpact was composed specifically to handle the Pentacle. In a sense, the Shadowpact could be viewed as good Psycho Rangers, making this an Inverted Trope.
In Batman and the Outsiders, Maxie Zeus formed a team called the New Olympians with each member being a counterpart to one of the Outsiders. Specifically:
The Dark Avengers are an interesting example; a supposed hero team who are actually posing as their counterparts. In addition to Ares and Sentry as themselves (going along with it because one's morally ambiguous and the other's just plain nuts - though Ares replaces Thor and/or Hercules to some extent), the line up includes Venom (Mac Gargan, previously known as Scorpion) as Spider-Man, Moonstone as Ms. Marvel, Noh-Varr as Captain Mar-Vell, Bullseye as Hawkeye and Daken as Wolverine. Norman leads the team as the Iron Man-Captain America mashup Iron Patriot.
Osborn later revived the Dark Avengers concept with a new team featuring Skaar, Son of Hulk (The Hulk/Red Hulk); Hawkeye's brother Trickshot (Hawkeye, duh); The Gorgon, Wolverine's deadliest enemy (Wolverine); Ragnarok, the infamous robotic clone of Thor (The Mighty Thor); Ai Apaec, a sinister sort of arachnid god (Spider-Man); June Covington, a deranged geneticist Osborn met in prison (Scarlet Witch); and Superia, a Straw FeministMad Scientist with super strength (Ms. Marvel). Norman himself becomes the new Super-Adoptoid, making him the only Dark Avenger without any real analogue. Skaar turns out to subvert his role, being Captain America's Mole in the team.
Though the Dark Avengers didn't match up well with the actual Avengers they faced. For instance, there was no counterpart for Luke Cage in either incarnation, and neither team of Dark Avengers actually fought a team with Hawkeye or Scarlet Witch as members. Likewise there was no Hulk on the team when Skaar was part of the Dark Avengers, and so on.
The funny Sixth Ranger Speed faces Coat Of Arms, a crazy fangirl.
For unknown reasons, Hulkling doesn't have a counterpart in the other team. The Dark Young Avengers are somewhat unusual, because the Dark Young Avengers were not gathered together to fight the original Young Avengers, but just want to be heroes. However, they will probably end up under Osborn's control. What's more, some relationships between the members of the Dark Young Avengers mirror those in the Young Avengers. just like Stature and Vision love each other, Big Zero has a crush on Egghead.
The Dark X-Men feature: Dark Beast (Beast), Mimic (Angel, Cyclops; he has the powers of the original five), Daken (Wolverine), Mystique (Jean Grey). When Emma Frost was a member, she was the counterpart of Professor X, as both a psychic and a teacher.
And for all of Osborn's "Dark" teams, it should be noted that those were just the titles of the books. Osborn was a Villain with Good Publicity and the public (and most any individual member you're surprised to see on these lists) thought they were truly there to do good. All this is in the aftermath of Civil War, and Osborn was promoting his teams as the only real Avengers, etc. unlike those outlaws who were operating without the legal right to do so.
In one of the X-Men First Class issues, the random kids in the coffee shop who correctly guess the team's orders before they're made (and just-so-happen to resemble the team greatly) turn out to be Skrull imposters that have been masquerading as the X-Men and causing havoc.
The original Soviet Super Heroes team primarily featured clear counterparts to The Avengers team they often opposed. Perun, the Slavic god of thunder, was the Thor counterpart; Sputnik/Vostok, a calculating android, was the Vision's counterpart; the Red Guardian, uber-patriotic Soviet supersoldier, was the Captain America analogue; Surge, a man in a suit of Powered Armor, was Iron Man; the feral Sabercat was the Beast, weapons expert Vanguard was Hawkeye, the mystical Darkstar was the Scarlet Witch, etc.
Another case of the Psycho Rangers not actually facing their counterparts (because they're dead) is the team of knock-off New Gods that have bedeviled the Justice League of America: Dr Impossible, the evil Mr. Miracle from an early storyline, is now joined by Hunter (evil Orion); Neon Black (evil Lightray); Chair (evil [and dumb] Metron); and Tender Mercy (evil Big Barda).
The Liberators from volume 2 of Marvel's The Ultimates are an Axis of Evil counterpart to the title team. The Colonel being the Iranian counterpart to Captain America, Abomination the Chinese Hulk, Crimson Dynamo the Chinese Iron Man, Perun the Russian Thor, Hurricane the North Korean Quicksilver, and Swarm the Syrian Wasp.
There were later the Dark Ultimates, the Ultimate counterpart of the above-mentioned Dark Avengers. Reed Richards acts as the team's leader and Iron Man parallel, while the Hulk acts their counterpart to Thor. The rest of the team however (Kang, the Human Torch, and Quicksilver) don't match up as exact analogues to the Ultimates.
In Rawhide Kid: The Sensational Seven, when the Big Bad learns that the Rawhide Kid and the Seven are coming for him, he recruits a team composed of villainous counterparts of the Seven.
The White Lions were the Nazi counterpart to the heroic Blackhawk Squadron.
Inverted in The Flash with the Renegades, a group of 25th century policemen who model themselves after the Rogues, since the 25th century's most dangerous criminal is the Flash's Evil Counterpart.
In Archie Comics' Sonic the Hedgehog, there's at least three groups. The first is the Suppression Squad, Mirror Universe counterparts of the Freedom Fighters. The second is the Destructix, a group of mercenaries led by Scourge the Hedgehog, Sonic's Mirror Universe counterpart, and his girlfriend Fiona Fox (which may be a jab at Sonic and Sally being unable to stay together). Eggman later unleashed a series of Metal-series bots comprised of Metal Sonic, Metal Tails, Metal Knuckles and Mecha Sally.
In Les Légendaires, Anathos, after defeating and brutally scarringthe Legendaries, use the blood they left behind them to create magically engineered clones of them in order to prepare for their return. Referred as the Hellions ("Infernaux" in french), those clones were identical to their heroic counterpart physically, except for their skin/hair/eyes colours, and used the same names with the prefixe "Dark" (Dark-Shimy, Dark-Jadina, etc). Much like the original Psycho Rangers, they possessed upgraded version of the Legendaries' abilities and psychotic personnalities. Ironically, they still ended up biting the dust, since the Legendaries Took a Level in Badass by the time they had to face them.
Infinity War, the sequel to The Infinity Gauntlet took this trope for all it was worth by creating an entire army comprised of evil counterparts of nearly all the Marvel Comics heroes at the time.
The Pride were this for Runaways. Bonus points for being their parents, so each pair served as this for their respective kid, either playing on similarities or contrast between them:
During the "Transfer of Power" arc, The Authority were replaced by the G7 Authority, made up of corporate- and government-backed versions of each member. Jenny Sparks was replaced by the Colonel (of Britain); Swift was replaced by Rush (of Canada); Hawksmoor was replaced by The Street (of America); The Engineer was replaced by The Machine (of Japan); Midnighter was replaced by Last Call (of Italy); Apollo was replaced by Teuton (of Germany); and The Doctor was replaced by The Surgeon (of France).
In My Little Avengers, Loki eventually assembles a team of Dark Avengers to combat Thor's Avenger team, selecting ponies whose powers make them Evil Counterparts to the heroes, with Loki himself serving as Thor's counterpart. The only standout is Loki's apprentice Trixie, who has no counterpart among the main characters — though this admittedly becomes a moot point by the Final Battle, as by then, Trixie's failed an attempt to double-cross Loki and has fled for her life, and in any case, all the Avengers (except for Thor, who still takes on Loki) swap opponents in order to get an advantage.
A rather interesting case in Pretty Cure Perfume Preppy. The Akutare brothers, managers of the Sunday Scent Shop, oppose the girls in episodes 16 and 17... But the girls are five, so neither Ayameko nor Hanae have counterparts.
In the Haruhi Suzumiya novels, the whole SOS Brigade is diametrically opposed by the Anti-SOS brigade, a team consisting of a time traveler, an alien humanoid-interface, an esper, and a depowered version of whatever Haruhi is. Ironically, Mikuru's opposite more closely resembles an Evil Counterpart to Itsuki (something Kyon even comments on), while Itsuki's opposite would be more suited as an Evil Counterpart to Mikuru. Pointedly, the only thing missing is a Kyon-counterpart. The Anti-SOS make several attempts to recruit Kyon, instead, believing him critical to their plans and fueling a great deal of Wild Mass Guessing. However, this trope is ultimately subverted, in that the Anti-SOS Brigade are not in any sense a coherent group, and its members do not actually care about each other at all, as shown by the fact that there are four of them but are split into at least three factions. In fact, Sasaki disagrees completely with what the other three want, so much so that she tries to help Kyon oppose the others.
The City of HeroesExpanded Universe novel The Freedom Phalanx has the Tyranny Legion, Psycho Rangers for the not-yet-formed Phalanx. The armored hero Positron has his old boss, Doctor Null, who's stuck inside his armor; Synapse, who got his powers from one of Null's experiments, has Revenant, his ex-friend who was turned into a zombie through a similar experiment; Sister Psyche, the mutant psychic, has the Shadow Queen, whose psychic powers come from a possessed mask; Manticore, a Batman-esque vigilante, has Protean, the shapeshifter who killed his parents; and, of course, Statesman has Lord Recluse, whose rivalry the entire game revolves around.
The ghostwritten "Tom Clancy" Op-Center series has the titular crisis command headquarters and its Russian counterpart, Mirror Image. Sometimes they cooperate, sometimes not.
In Animorphs, David's ultimate plan for the blue box was to use it to create a gang of morphing criminals to counter the Animorphs. The Animorphs were able to defeat him before he could put this plan into action.
Live Action TV
During the Angel Season 4 finale, each member of Angel Investigations is given a tour of the rebuilt Wolfram & Hart by a somewhat dark mirror of each member:
Lorne's guide is Preston, a slick, fast-talking talent agent.
Gunn gets Lacey Shepherd, a mysterious afroamerican woman who just-as-mysteriously vanishes.
Fred's tourguide is Knox, a morally ambiguous geeky scientist and the only one to become a recurring character. He worships an Eldritch Abomination and will eventually cause her death.
Wesley's guide is Rutherford Sirk, a former Watcher.
Angel gets undead Lilah.
An episode of The A-Team had a group of bad guys put together their own squad to beat the heroes.
Beetleborgs features the Mantrons, which are not Psycho Rangers to the Beetleborgs but rather to the Beetleborgs' allies, the Astralborgs.
The season six finale of Charmed featured an alternate universe where the role of good and evil were switched with the humans/witches as evil and the demons good. The sisters met their evil counterparts as well as counterparts for Chris and Leo. They tried fighting them but of course came to a draw. A subversion then happened where they decided to work together for their respective greater good/evil.
They had to fight two more sets of Psycho Rangers before that. First in a season one episode it was a trio of Warlock brothers, though one was saved by becoming a priest. Then also in the sixth season, it was a trio of three evil witch sisters - the Stillmans. They stole the sisters' powers and rewrote reality to steal their identities too. Oh and they were blonde.
The murderer and the murdered in the "Butterflied" episode are Grissom and Sara's evil counterparts. The Miniature Killer and Ernie Dell are also clearly intended to be evil mirror-images of Grissom and Sara.
There was an episode where Grissom was interviewing a suspect, and the actor had been carefully styled and lit so that from certain angles he looked like a mirror-image of Grissom. The suspect was a shrink who turned out to have been administering some BDSM therapy to one of his patients, who then turned up as the corpse-of-the-week.
Kamen Rider has the Shocker Riders of the original series, a group of evil copies of Kamen Rider 2. Subsequent Showa era series use evil copies of main Riders fairly often - if the Scarf of Asskicking is yellow instead of its usual color, that's not your beloved hero and you should probably start running. Later series forgo this in favor of newly designed evil riders.
Kamen Rider Spirits redesigned the Combatroids from Kamen Rider ZX into ZX-styled Shocker Riders; additionally, the Big Bad Judo could also qualify, since he has the ability to transform into any of the Kamen Riders preceding ZX and use their powers.
Kamen Rider Decade has the same powers as Judo above, except that the Riders he can transform to span Kamen Rider Kuuga to Kamen Rider Kiva. Also, one of the worlds his crew visited was the Negative World, where evil Riders and monsters rule supreme and normal humans are killed on sight, all but extinct. There was no evil doppelganger of Decade himself, but instead he fought against evil Riders from past series - Ryuga, Alternative, Orga, Dark Kabuto, and Dark Kiva. Dark Kiva himself is an Evil Twin of a heroic character from Kiva, and acts as the group's leader.
The video game Climax Heroes introduced the non-canon Dark Decade, a black, gray, and gold Evil Twin of Decade who fulfills the aforementioned Dark Riders' role in the game's reimagined version of the TV series plot.
Kamen Rider Gaim plays this trope the straightest (ironic given that its written by Urobuchi) with the original Armored Riders being opposed by Yggdrasill's New Generation Riders.
Gaim to Zangetsu-Shin, both are based on samurai's are the most moral Riders and while Gaim is an All-Loving Hero who wants to save everyone Zangetsu-Shin is a Dark Messiah who is willing to sacrifice anything to save humanity.
Baron to Duke, both are based on knights but are anything but chivalrous and while at first they appear different, Baron is an up front Anti-Hero while Duke is a quirky Mad Scientist they are both revealed to be Social Darwinists willing to sacrifice anything to attain unlimited power.
Ryugen to Marika, both are based on foreign warriors (Chinese and Arabian) both have Undying Loyalty to another Rider at first, but as time goes on they both develop separate agendas.
Gridon to Sigurd, both are based off of Vikings and both are the most manipulative of their respective Rider group while being the most amoral members. But as of now, the similarities stop, as Gridon devolved into a Joke Character with barely any screentime, while Sigurd turned into The Starscream to the other Energy Riders.
The Big Bad in The Legend Of Dick And Dom creates Evil Twin versions of all the heroes, to do evil deeds that the heroes will be arrested for. They are fairly easy to spot, however, as they all have a highly unconvincing black goatee, including the woman in the group.
In the Leverage episode, "The Two Live Crew Job", the team squares off against a group of thieves who are just as skilled as they are in their specialties. Bonus points for the crew being played by people who have the same skills as their characters.
By the end of the second season of The Sarah Connor Chronicles, Weaver, John Henry, Ellison and Savannah were the morally ambiguous, if not dark, mirrors of Sarah, John, Derek and Cameron.
Stella featured an episode where Michael Showalter and Michael Ian Black leave the group, leaving David Wain to find his own new comedy-triad. He changes his name and ditches the Stella-trademark business suit and moves in with two completely normal roommates, who are so mundane as to be eerie in comparison to the creepy and latently-homoerotic Stella group. At the end of the show, the new roommates flee to Italy in a sequence similar to the Sicily sequences in The Godfather.
In Robin of Sherwood, the Sheriff of Nottingham once hired a group of lookalikes to pose as the Robin Hood gang and commit violence against the peasantry. In addition to evil Robin, there was an evil Tuck, an evil Will, an evil Little John, and an evil Nasir.
CHIKARA had a stable called GEKIDO consisting of 17, The Shard, and The Swarm (combatANT, assailANT and deviANT). They were evil counterparts of Chikara's mainstay faces Mike Quackenbush, Jigsaw, and The Colony (Fire Ant, Soldier Ant and Green Ant).
The Japanese promotion HUSTLE had a stable named Monster Kamen Rangers, which were evil clones of the face team HUSTLE Kamen Rangers. They were able to defeat them repeatedly, as they knew their fighting style, and even kidnapped Yellow Ranger, The Big Guy of HUSTLE Kamen Rangers, in order to turn him evil and destroy them. Finally the HUSTLE Rangers won when Yellow turned good again thanks to The Power of Friendship.
BIONICLE had the Shadow Toa, illusory copies of the Toa that could only be defeated when the heroes acknowledged that the darkness was a part of themselves.
Similarly, the Bohrok-Kal and Piraka Gang are separate groups with elemental powers. The Piraka Gang almost managed to pass themselves off as the real deal (It helps that the townsfolk being fooled had never seen a Toa before).
The Makuta of the Karda Nui saga were the closest in toy form. They even came with their own "evil" matoran, who could latch on and connect to them in the same way as the Toa from the set and were the first villains to feature Kanohi Masks. Originally there was to be a genuine Shadow Toa set, but it was cancelled in the prototype stage.
Sailor Moon: Another Story introduced a plot "between" seasons of the anime, and had the Opposito Senshi, evil counterparts to the Sailor Team named after Babylonian and Mesopotamian gods (which, in turn, were the names of the corresponding planets in those cultures). Despite appearing almost to be twins of the Senshi, the game passes off their similar appearances and corresponding names as a coincidence.
Sin is Sailor Moon's counterpart (named for the Babylonian god of the moon, Sin, not the English word "sin").
Nabu, named for the Mesopotamian god of Wisdom, is the brainy Sailor Mercury's counterpart.
Nergal, named for the Mesopotamian god of war, is the counterpart of Sailor Mars.
Marduk, Sailor Jupiter's counterpart, is named for the leader of the Babylonian gods.
Ishtar, in addition to being a bad movie, was the Babylonian goddess of love, and a fitting name for Sailor Venus' counterpart.
Star Wolf in Star Fox, though mostly in Star Fox 2 and Star Fox 64 (Wolf is the leader, and the team is named after him, like Fox - also, both the wolf and the fox are canines - ; Leon is implied to have had run-ins with Falco in the past, probably when the latter was still a gang member; Pigma was a member of the original Star Fox team, like Peppy; and both Andrew and Slippy seem to have some technological background. In later games, the team was splintered; currently, only half of the original group remains, and the new members don't have a clear counterpart in Star Fox (what with Krystal briefly joining them in Command after leaving Star Fox).
In Sonic Adventure 2, Team Dark consisted of Shadow, Eggman and Rouge: three villains with the same powers and move sets as Sonic, Tails, and Knuckles respectively. They'd return with some adjustments as an Anti Hero Team in Sonic Heroes: Rouge moved from Knuckles' counterpart to Tails', and Eggman was replaced by new character Omega, who filled the "Anti-Knuckles" slot.
The Hell Hounds in Galaxy Angel, a group of mercenaries that just happened to have a grudge or other fixation with each of the specific Moon Angels. In the second game, they were replaced by actual robot duplicates of the Angels, foreshadowed by the brief presence of a robotic Tact in the first game. The fake Angels were the only villains to carry over to the Galaxy Angel anime, although they only appeared for one episode.
The God-Generals of the Order of Lorelei in Tales of the Abyss. All but one of the God-Generals are a clear Evil Counterpart of one of the party members, be it by abilities or role, personal relationships, or both: Asch to Luke, Legretta to Tear, Arietta to Anise, Dist to Jade, and Largo to Natalia. However, despite some initial Red Herring comparisons, the last God-General, Sync, is actually the counterpart to Fon Master Ion, not the last party member, Guy. His counterpart turns out to be the God-Generals' leader, Van.
To drive the point further, the counterparts actually share certain artes with the party members. Some of them are justified, as Legretta personally trained Tear, Luke and Asch had the same mentor, and Anise and Arietta were both trained to be the Fon Master Guardian. But when you have Largo shooting a giant electric beam from his scythe/axe...
Sync manages to share his Akashic Torment Mystic Arte with his counterpart despite Ion not even being playable. It's not named as such, but the animation is recognizable in Ion's extension to Luke's Radiant Howl Mystic Arte.
Don't forget the villains of Wild ARMs 5. Everyone has a rival character that acts as an opposite to them. Light-hearted and idealistic leader Dean has the defeated dog of the villains Nightburn, The Chick Rebecca ends up rivals with Dark Chick Persephone, family man Greg fights his family's killer and Ax-Crazy Kartikeya, Avril has story reasons for rivaling dark leader Volsung, small but heavily armed Carol fights against her former caregiver and muscular Elvis and Chuck rivals the surprisingly noble Fereydoon.
Advance Wars has the Black Hole army, with Hawke for Andy or Eagle (The first because both heal their own men and have no weaknesses, the second because of their names and appearance), Flak for Max (both are very formidable in a straight fight), Lash for Sonja (both have abilities related to terrain and are intelligent young girls), Adder for Grit (again mainly going by appearance, but both aren't particularly trustworthy and have similar tastes in clothing) and, arguably, Sturm for Olaf (skilled in slowing terrain, with "hurt everybody" CO powers).
Alter Echo pits the heroic shaper Nevin and his teammates, the gruff gun-toting Stome and the blade-wielding Action Girl Arana against the evil shaper Paavo and his bodyguards, the idiotic gun-toting Gherran and the blade-wielding Psycho for Hire Kess.
Jon Irenicus in Baldur's Gate II is powerful enough to create a group of identical copies of your party with one spell, although they are relatively easily defeated because they lack many of the originals' more special powers.
Team Fortress 2's savage Builder's League United (BLU) forces are a carbon copy of noble Reliable Excavation Demolition (RED) armies created to snatch corporate and industrial dominance away.
Or is it the other way around? I can never remember.
And now there's the Robot Army, an army of robotic knockoffs of the mercs.
In Ultraman Fighting Evolution Rebirth, a trio of evil Ultras are introduced. Chaosroid U, a clone of Ultraman, Chaosroid S, a copy of Ultraseven, and Chaosroid T, Taro's counterpart. While they're fought one by one by their counterparts, they attack Nebula M78 as a team and capture two important artifacts of the Ultras, Chaosroid S stealing the Ultra Key and Chaosroid T steals the Ultra Bell while Chaosroid U comes close to stealing the Plasma Spark. In addition to the powerful weapons they steal, S has the ability to split his Eye Slugger into a huge number of weapons and Chaosroid U is more powerful than Ultraman, until the Plasma Spark reenergizes him and let's him blow U away with the Giga Specium Beam.
In Battle Realms the Serpent clan is the yin counterpart of the yang Dragon clan.
Hexen has Zedek, Traductus, and Menelkir, a trio of Dragons who are clones of the three player character classes. Each uses the most powerful weapon of his class.
The X-Wing games tend to do this. Especially X-Wing vs. TIE Fighter, since some training exercises come both in Rebel and Imperial versions: Z-95 Headhunters correspond to TIE fighters, X-wings to TIE interceptors, Y-wings to TIE bombers, and B-wings to TIE defenders.
The Dark Aeons from Final Fantasy X are evil versions of all the Aeons that can be obtained in the game and boast higher HP, super powerful attacks and evil colour schemes. Though they are fought separately, the Dark Magus Sisters are fought together thus invoking the trope. Your normal Aeons will take on the appearances of the Dark Aeons at the end when Yu Yevon possesses them. They reappear in the sequel as possessed once again.
In Ultima IV, the final fight is against the "evil yous", a team of evil copies of your party.
The commanders of Ruin match up against the Savior class in this manner in Duel Savior Destiny. Shezar against Berio, Mudou against Kaede, Imnity against Rico and Lobelia against Nanashi or to be more accurate against Rubinas, Nanashi's alternate self. Lily and Mia are largely left out of this equation since they actually seem to match up against Muriel and Taiga instead. The Big Bad goes against Taiga, of course.
The Axem Rangers in Super Mario RPG serves as being counterparts to your party with each ranger specializing in different abilities that are similar to your own and also inheriting similar weaknesses.
Super Robot Wars Z: Special Disk gives us "Death Squad 13", Edel Bernal's attempt at forming a ZEUTH-style Ragtag Bunch of Misfits. It begins as a unit composed of Phantom Pain and Titans members under the orders of Neo Roanoke, then gains more members from mercenaries like Timp or Jason Beck, and others like the Frost Brothers and Gym tagging along for fun. It doesn't work nearly as well (most members are nuts, after all) and the squad ends up disbanded without ever meeting ZEUTH in combat once.
Inverted in in 8-Bit Theater with the Real Light Warriors who are the strong, brave, wise and merciful warriors destined to save the world, contrasting with the team of jerks we follow. Except they don't. A team of four white mages saves the world.
There are two other examples that follow the trope a bit more closely, as well. First there's the Dark Warriors, with the technically-a-villain-but-actually-really-nice Garland (as opposed to the technically-a-hero-but-actually-evil Black Mage), the haughty dark elf Drizz'l (as opposed to haughty regular elf Thief), incalculably stupid pirate Bikke (as opposed to incalculably stupid Fighter), and LARP fan Vilbert (as opposed to pen and paper roleplaying enthusiast Red Mage).
Finally, there are the Other Warriors, made up of the shady and unethical Rogue (Thief), the rule-bending Ranger (Red Mage), the normally friendly but incredibly vicious Berserker (Fighter), and Cleric (Black Mage). Cleric doesn't fit quite as well as the others until you notice that he deliberately plays the Gods themselves against each other to increase his own power.
The Linear Guild in The Order of the Stick, were deliberately chosen by their leader to be this. This gets to the point that he's unwilling to face the Order of the Stick without a full team of evil counterparts, because he's invested so much time and effort into cultivating that identity of them as a team. At one point, he even gets a Token Good Teammate to counter Belkar.
In Shortpacked!, a minor character who was fired instead of a major character forms a team of other minor characters into a league of minor evil.
The T-Girls of Jet Dream face off against another all-girl flying team, Raven Red and her Dynamic Dare-Dolls. Each of the Dare-Dolls fits a national stereotype that isn't "covered" by one of the T-Girls.
While outnumbered and outclassed, Trey and Troy, the "bad" Dimensional Guardians from the web fiction serial Dimension Heroes, go out of their way to pick fights with the protagonists.
Almost every subgroup has a counterpart team on the opposite side in Transformers. The Triggerbots and Triggercons, the Protectobots and the Combaticons, the Aerialbots and the Stunticons, etc.
The G1 origins of the Aerialbots and Stunticons are an inversion, with the former created by the heroes to counteract the latter.
"Megatron wants to battle us on the roads. We'll fight him in the skies!"
What's ironic about this is that the Stunticons themselves are a type of Psycho Rangers for the Autobots as a whole. They were created by Megatron because he wanted a unit of car-based warriors to counteract the Autobots, the vast majority of whom had car-based alternate forms.
Due to a shortage of Autobot combiners, however, the Constructicons and Predacons never had exact opposites. The Dinobots and/or Omega Supreme were the arch-enemies of the former, and Sky Lynx was the enemy of the latter. (Despite being small compared to Predaking, Sky Lynx has defeated them more often than not. Because he's that good. And knows it.)
Trigon created evil versions of Starfire, Beast Boy, and Cyborg. The clones proved to be too much for their original counterparts to defeat, until the Titans switched opponents, which allowed them to come out on top.
Two counts in Recess, though neither was exactly evil: once when Lawson decided to put together his own crew to rival TJ's, and once when the main characters went to a school that was full of kids who paralleled the students at Third Street School and had to play kickball against their own doppelgangers.
Also, in one episode Oleander created her own team of living food fighters to counteract the Sushi Pack. Unfortunately, she made them too much like the Pack, and the two teams were able to see past their differences. That, and she tipped her hand too early (she was planning on eating both teams), so they all teamed up to defeat her instead of each other.
The Anti J-Team in Jackie Chan Adventures, comprised of criminal counterparts of Jackie, Jade, Viper, El Toro, and Tohru.
The Delightful Children From Down The Lane in Codename: Kids Next Door look eerily similar to Sector V. The movie reveals that they were once the lost team from Sector Z.
Another episode, Operation: P.O.O.L., introduces their Mirror Universe counterparts, the Destructively Nefarious Kids. Their personalities were the opposite of the "positive" group.
CHYKN in W.I.T.C.H.. Formerly the team that did the job WITCH does now, Season 2 Big Bad and Fallen Heroine Nerissa used them to go up against the current team. Of course, for her to pull that off, she ended up having to capture and brainwash three of her former allies (Kadma, Halinor and Yan Lin), create an Altermare of one of the three so she could be evil (Yan Lin, which led to her granddaughter Hay Lin's Heroic BSOD) and resurrect a fourth whom she killed many years ago (Cassidy). Of course, this didn't mean much: they were defeated a few episodes after their reunion and put back inside the Seal of Nerissa for the rest of the season, until she was defeated by WITCH.
CHYKN was technically stronger than WITCH because they had two Amplifier Artifacts to their one, but because they were mind-controlled their reliance on Nerissa meant they were screwed if she was distracted. Nerissa, being Dangerously Genre Savvy changed tactics and later used them to attack WITCH when they were split up and not transformed.
One of the Big Bads of Teenage Mutant Ninja Turtles: Fast Forward created mutated clones of the turtles, one for each, and they were even called the "Psycho Turtles". In a reversal of the above Titans mention, the Turtles used knowledge about themselves to defeat their evil counterparts without switching opponents, although typically they do switch opponents. Also, like the original "Psycho Rangers", these clones lasted past the end of the season.
In the original Teenage Mutant Ninja Turtles series, the Punk Frogs are a notable subversion. While Shredder did (indirectly) mutate them from ordinary frogs, going as far as to teach them how to fight as well as even naming them based off his heroes such as Napoleon Bonaparte and Genghis Khan, he had to trick the Frogs into believing that the Turtles were the bad guys in order for the Frogs to fight them. When they find out the truth, the Frogs instantly turn against him.
Played straight and subverted on Justice League. In the original, there were three versions of the Injustice Gang. However, only the third was made of any form of counterparting to the seven members of the League (and even then, the relations were stretched at best), and the fights for each tended to trade off who fought who every time. In Unlimited, the various Injustice League members merged into the Legion of Doom, which had grown in response to the Justice League's growth. It should be noted that the villain The Shade has the distinction of being on all four Injustice Leagues. (He points this out at the third Injustice League formation, to which the villain recruiting him replies "Third time's the charm".)
In the Grand Finale, when the Legion of Doom and the Justice League were about to come to blows, there was an excellent shot of everybody facing off with their Evil Counterpart: Green Lantern vs. Sinestro, Superman vs. Bizarro, Atomic Skull vs. Captain Atom, Giganta vs. Iron Giant, Volcana vs. Fire...and Batman standing alone, since nobody is cool enough to beat Batman. Or because of the Bat embargo, none of his rogue's gallery could appear.
ReBoot featured a game where the heroes had to fight game sprite copies of themselves in the final level.
Clones of the protagonists from Gargoyles. Subverted in that only Goliath's clone Thailog was actually evil. But they did have the same fighting their doubles problem.
In the comic book continuation, Lexington's clone Brentwood chose to stick with Thailog. He's portrayed, like the rest, as more gullible and naive than actually evil.
One episode of Class of 3000 features the Westley kids going up against their counterparts from Eastley, all of whom wear red and black Reich-style uniforms. Coincidentally their teacher looks nothing like Sonny.
In season one of Alpha Teens on Machines, Payne and his two henchmen goes through Terrible Interviewees Montage to find somebody they can hire to fight titular team. After few failures they finds out five maniacs who happens to have similiar skills and opposite personalities to the members of A.T.O.M.. Seson two has Mu-Team, A.T.O.M.'s evil clones mixed with animals whose natural abbilities could improve their skills. Shark's clone was mixed with an actual shark to make him even better swimmer, Hawk's with hornet and bee so he can use his piloting talent to control himself while flying, King's with rhino to make him stronger, and Axel's and Lioness' with snake and cat respective, to increase their agility.
In the episode "Citizen Ghost", Peter Venkman recounts how Slimer first came to stay with the Ghostbusters after the Gozer incident. They received new uniforms to replace their original uniforms, which were heavily contaminated with ectoplasm. The ectoplasm later animated the old uniforms, creating four ghostly doppelgangers of the Ghostbusters, out to take down the originals, until Slimer ended up saving them.
The Peoplebusters in "Flip Side" are a similar set of ghost versions of the Ghostbusters (minus Winston) from an alternate universe version of New York. Even their power sets are flipped, as humans fly and pass through walls in this reality, while the Peoplebusters have their own version of the proton packs (which shoot slime to entangle the Ghostbusters).
The Avengers: Earth's Mightiest Heroes has the main heroes fight evil versions of themselves twice. The first time happens when they have to save Wakanda from getting invaded by shape-shifting Skrulls. The second happens when Ultron decides to replace all the humans in the world with emotionless robots, and replaces some of the Avengers first.
