"Guilty! Guilty! My evil self is at that door, and I have no power to stop it!"
When someone's inner darkness
doesn't quite take over someone
, but it does "escape" their body and rampage. Fighting someone else's Enemy Without is tricky, as often it will either kill the person projecting it if it dies
, or it will just resurrect itself
until the actual darkness in the hero's heart is dealt with by the hero themselves.
Often symbolically represents repression, and the hero's refusal to acknowledge the darkness within or some other aspect of themselves. Victory is achieved half the time via "reintegrating
" with it. The other half of of the time it can be seen as representing some inner demon, and thus, it must be abandoned, purged, or confronted and conquered.
Sometimes this battle will occur inside someone's own head
in a dreamscape
, making it both the Enemy Within and the Enemy Without at the same time. It may require saying "I'm Not Afraid of You
!" to weaken it enough to beat.
This trope is very similar to The Heartless
, Made of Evil
, and Literal Split Personality
. It is distinguished from The Heartless by having some personal connection to the person/people it was created from, from Made Of Evil because the Enemy may be flesh and bone, and from Starfish Character
by leaving behind a clearly-defined original character.

The "evil" is usually part of a character's Soul Anatomy

Anime and Manga
- In Gunnm/Battle Angel Alita, Kaos's backstory is that Den was originally Kaos's evil impulses that occasionally surfaced to do evil things, and Kaos's father, Desty Nova, found a way to pull Den out and give him a body of his own, leaving Kaos free of Den's influence.
- In Magic Knight Rayearth, Nova was the suppression of Hikaru's hatred for herself, given physical form by the magic of Cephiro.
- Madlax was a benign version of this; in this case, she was the sublimated desire of a young girl to kill her Brainwashed and Crazy father in self-defense. Uniquely, she grew up on her own without too many defects, as a relatively friendly mercenary in a war-torn land.
- In Animerica, Kiyone's Enemy Within becomes this in Season 3, having "escaped" his body when he felt remorse over Yumi's death but finds his way back when his good side was just broken out of his Driven to Suicide state and accepted Ron's words, angrily refusing to let him perform a Heel-Face Turn. He attempts to give him another Breaking Speech, but is promptly told to shut up by his good side, telling him that he no longer has a purpose to be evil and wants to change for the better. This, followed by the power that the "true" Golem unlocks within him, triggers one of the best Crowning Momentof Awesome in the series.
- In Bleach:
- Ichigo has to battle his mirror self inside a dreamscape first as part of training from Zangetsu and later because the mirror has taken over Zangetsu and is trying to take over Ichigo too. In this case, it is resolved via reintergation by conquering.
- The mirror self is Ichigo's "inner-hollow" who takes over Ichigo's body (gradually turning more and more hollow like) during their showdown and the Visored have to fight him to keep him from transofrming completely and killing everyone in Karakura town
- It's mentioned later on that forcing a Shingami's zanpaktou to manifest, then submit to you, is a required technique for accessing the second release.
- All of this leads up to The Reveal that the "inner-hollow" is the true Zangetsu, and that it was never really his enemy.
- Dragon Ball:
- Piccolo begins his existence as Kami's cast-off evil side. The original "King Piccolo" in Dragon Ball is evil, but his son / reincarnation, "Piccolo Jr", gets a lot of Character Development. Firstly, he's less interested in harming innocent people For the Evulz than he is in killing The Hero for revenge. Then he finds himself reluctantly fighting alongside the good guys when a greater evil shows up. Then he kidnaps his rival's son and puts him through Training from Hell, but gradually comes to care for him to the point of Taking the Bullet. As the Sorting Algorithm of Evil keeps churning out worse and worse villains, Piccolo Jr comes across as more and more heroic, and eventually he and Kami agree to a Split Personality Merge for a powerup.
- Piccolo further attacks this trope with one of his methods of training: he creates a second instance of himself (which, unlike Tenshinhan's technique, emerges out of the original). The two Piccolo bodies are not a full split, as the personality remains one and whole, controlling them both; their brutal sparring is nonetheless a cool parallel on the inner struggle he must be going through during his gradual Heel-Face Turn.
- Played straight with Majin Buu. His evil side comes out, fights him, then turns him into chocolate and eats him. Later reversed, when Buu's good side gets loose, and fights the evil side (who is now even worse than before). By the end of Dragon Ball Z Buu has two good sides; himself and the human Uub (a purified reincarnation of the evil one).
- This is part of the plot of Seven of Seven. The main character, Nana, is an ordinary schoolgirl who finds herself with six alter egos representing different aspects of her personality (hot-headed Nanappe, cheerful Nanacchi, sensitive crybaby Nanarin, lazy and laid-back Nanakko, intellectual Nanasama, and eccentric Nanapon) after messing with one of her inventor uncle's experiments.
- An episode of Sgt. Frog is a direct spoof of Seven of Seven: Giroro acquires a sextet of alter-egos representing parts of his personality after an encounter with one of Kululu's inventions. The gag is, only one is obviously part of him (his "inner soldier"), and the others much less so, like his inner coward, his romantic side, and his feminine and poetic sides, the last two female!
- This happens twice and in two variations in the anime version of Ranma ½. The first time Ranma was split into his female (and evil) self and his male (and normal) self. The second time he found a way to physically fight his shadow, and inevitably, the shadow turned out to be slightly evil because it lacked a superego.
- In the manga this trope is not used (More precisely, in an episode there is a double of a female Ranma; but she is not a double but a ghost that, being sealed in a mirror, manifests herself looking as a female Ranma).
- Magical Girl Lyrical Nanoha A's has the corrupted self-defense program that separated from the Book of Darkness once Hayate became its master. It was even explicitly called the "darkness of the Book of Darkness" by Hayate.
- Subverted in the Touhou doujin Remily the Strange. When Remilia looks into a cursed mirror, it creates a doppelganger that's supposed to represent the victim's repressed evil. However, Remilia is already completely evil, so the doppleganger ends being extremely timid and "spaced out".
- In the animated adaptation of Samurai Deeper Kyo, this was Onime no Kyo's revised origin; he was essentially the fighting instinct within the soul of Mibu Kyoshiro, distilled into a separate and powerful body the Mibu created. Onime no Kyo then became an actual person, as opposed to merely the nickname of the Blood Knight Mibu Kyoshiro.
- This situation, almost word for word was briefly dealt with in Naruto very recently wherein...at a waterfall...he had to get over his Dark Self, which for some, surprisingly was more of a reintegration instead of a total beatdown into submission , however - this was only a lead into tackling something far worse... battling the full rage of the Kyuubi.
- In Tekkon Kinkreet, this is one interpretation of the Minotaur. Specifically, the Minotaur symbolizes Black's inner darkness.
- Inverted in The Nineties anime version of Sailor Moon with Sailor Galaxia. Chibi-Chibi is the physical manifestation of Galaxia's Star Seed known by others as "The Light of Hope".
- Oto x Maho plays this one straight with Kanata, only to subvert a Mirror Match
- Subverted in A Certain Scientific Railgun. Kiyama created the Level Upper program that links espers together into a psychic network, making them capable of increasing their powers by drawing upon the collective's computational capability but at the cost of eventually falling into a coma. Kiyama, being the center on the network, can draw upon it to simulate their abilities herself... but when she goes overboard with her determinator tendencies, all the anger, disappointment and self-hate of the students who used Level Upper to realize their dreams peaks and erupts from her body into the AIM Burst, a fetus-like amorphous creature that wrests control of the Level Upper network away from her then goes on a mindless rampage. Oh, and not only attacking the AIM Burst just makes it grow bigger, it's also Mind Raping everyone connected into the Level Upper network while active.
- From A Certain Magical Index we have Misaka WORST, a second generation clone of Mikoto who is able to tap into the negative emotions that occur within the Sister clones via the Misaka Network. This can influence her behavior though, such as when Last Order has a fit of jealousy so does Misaka WORST.
- In King of Thorn we have Alice, who (as a result of abuse from her family) developed an alternate personality called Laloo to take the abuse for her. When Alice became infected with Medusa, it manifested from her back in the form of Laloo. How did Alice respond? By locking him in a room and burning the house down.
- Final episode of Black★Rock Shooter has Mato taking the mantle of Black★Rock Shooter and fighting Insane Black★Rock Shooter in a Battle in the Center of the Mind.
- A variation occurs in One Piece. Gekko Moriah's Shadow Shadow fruit allows him to steal the shadows of living humans and place them into corpses. This creates zombies with the personality and fighting style of the shadow and the physical strength of the corpse. This results in zombie versions of Luffy, Zoro, Sanji, and Brook. However, the actual bodies are very different from the originals, especially with Sanji (a penguin with a dog's face) and Luffy (Oars, a demonic-looking giant). Also, the zombies are really only evil because they are under Moriah's control. Only Brook and Luffy actually encounter their own zombies.
- Hilariously subverted in a Slayers OVA where Lina and Naga face a Magic Mirror which was built to create these for use against powerful demons. The problem is that it works too well, since the opposites of a truly violent being is a completely harmless one. Given that our heroes are Lina Inverse and Naga the Serpent, their respective doubles don't come out as planned.
- Professor X has attacked the X-Men via this method on a few occasions; once in the 90s cartoon, and several times in the comics, most notably as a fusion of his and Magneto's darkness, Onslaught.
- Marvel Universe character The Sentry's arch-nemesis, The Void, is his own personal Enemy Without. It's implied that the incident which caused The Sentry to be erased from the minds of the Marvel Universe's populace for about 30 years was a failed attempt at re-integration.
- In the UK's Sonic the Comic comic series (not the same as the Archie one), Sonic lost control when he turned into Super Sonic, becoming interested only in causing as much destruction as he could. Eventually, Super was split from Sonic, becoming a recurring antagonist in his own right, and later a pacifistic protagonist who knew nothing of his past or name and fearing having to use his powers to help people because of his Superpowered Evil Side.
- Shade, the Changing Man's Enemy Within, Hades, thanks to the power of madness, became an Enemy Without and an Ensemble Dark Horse in the same story arc. He also seemed to become less threatening and more helpful, so perhaps it's for the best that he vanished the scene before Spikeification set in.
- In an issue of the 2001 revamp of Doom Patrol, every member of the team is subjected to their own personal Hell. Deadpan Snarker Flash Forward, or Negative Man, is faced with eternity alone with nobody but another one of himself for company.
- In the Mirage Teenage Mutant Ninja Turtles comics, Casey's darker instincts, which had been personified in his mind into a darker, spikier version of himself, came to live when they took over the body of a shape-shifting comedian. Fighting ensued.
- Inverted in Calvin and Hobbes where bratty Calvin creates a clone of his good side. Interestingly played with; the good duplicate vanishes in a Puff of Logic when he has an evil thought, following prolonged exposure to the original Calvin.
- Adam Warlock originally had to deal with the Magus, his evil future self. Later on, as part of The Infinity Gauntlet storyline, he expelled both evil and good from himself to become a being of pure logic. The evil took the form of the Magus, and it was even implied that somehow this was the original Magus, using the evil expulsion as a way to resurrect himself. Once he was dealt with again, Warlock then had to deal with his good side, the Goddess, who had gone crazy and turned Knight Templar.
- Played straight with Nega-scott in Scott Pilgrim. This is odd when you consider how many tropes are played for laughs in it.
- The Spider-Man: India mini-series, in which the characters get their powers from magic rather than lab accidents, ends with the Goblin attempting to mystically provoke a Face-Heel Turn in Spidey. The process draws on his memories of being bullied, encouraging him to use his powers to take revenge. The 'darkness' eating away at Spidey during his temptation appears as an analogue of the Venom symbiote...which survives even after Goblin is defeated.
- Happened to The Creeper once, where he kept spawning increasingly chaotic and animalistic copies of himself. It was all pretty squicky, actually.
- Lex Luthor once exposed Supergirl to black kryptonite. It's not clear whether he knew what exactly it would do to her, but he hoped it would be bad. Well, turns out the stuff does this, and Kara had an evil doppelganger for a while. "Dark Supergirl" later resurfaced as an Enemy Within.
- Black Lantern Firestorm becomes one in Brightest Day. During the initial Blackest Night, the Ronnie Raymond Firestorm's body rises, and a Faux Affably Evil Totally Radical personality is born, possessing all Ronnie's memories. After Ronnie is brought back from the dead by the White Lantern, Black Lantern Firestorm remains as an Enemy Within. Soon afterwards, it gets out of the Firestorm Matrix, becomes its own entity and renames itself Deathstorm.
- Jamie Madrox's duplicates have minds of their own, and usually embody a specific aspect of his personality. If that aspect happens to be, say, his anger or self-loathing, it might just try to kill him on the spot.
- Les Légendaires has Elysio, a mysterious young amnesiac trying to find out who he used to be. To his horror, he eventually finds out he used to be Darkhell, the protagonists' Arch-Enemy and a cruel Evil Sorcerer who was The Dreaded in all his world. Hoping to prove everyone there is a mistake, he agrees to consummate a cure to his amnesia. When his memory starts coming back, he attempted to reject it, causing his Darkhell and Elysio personas to split into separate beings.
- Inner Demons: Throughout the story, Twilight has been controlled by her inner Darkness, which transformed her into the Queen of Darkness, the story's Big Bad. However, when the Elements of Harmony on used on her during the Final Battle, the Darkness is forced out of her body, only to take on a life of its own.
- Inverted in the Pony POV Series. During the final battle with Nightmare Whisper, Fluttershy's Superpowered Evil Side, Fluttercruel breaks out of her to help the heroes. Unlike most examples, this time it's a good entity previously contained in a now evil one that breaks free to help save the world instead of the other way around.
- In the Pony POV Series Chaos Verse (a recursive spin off of the above), the Big Bad is revealed to be one of these, specifically Nightmare Moon's essence, separated from Luna by the Elements of Harmony and given a life of its own as the Eldritch Abomination Nightmare Phobia.
- Subverted to hell and back in this Kingdom Hearts fic. Xehanort kidnap The Hero to infect Sora's heart with anger and vengeance, Sora turned himself into full heartless, allowing Roxas to take over his body without either of them losing too much strength, and thus bring their anger down on the Big Bad and try to avenge his victim. (as opposed of the half-state half-power they experience like in CoM and Days). Only because The Power of Love and Friendship helped.
- In Dragon Ball Z Abridged, Guru shares this relationship with Lord Slug, similar to that of Kami and Piccolo. That is, Guru is the evil half.
- Shadows Awakening: Near the end of the story, The Queen succeeds in corrupting Jade, causing the Tiger Talisman containing her to react by forcibly separating them, giving the Queen her own body, with all of the powers Jade had as a Shadowkhan.
- In the Danny Phantom fanfic series, Facing The Future Series, the separated ghost half that Tucker wished for makes a return.
- This is the premise for most of A Wizard of Earthsea.
- The Yamiko in Sailor Nothing (also The Heartless).
- Hunger in Matthew Swift is this for Robert Bakker. Unusual in that it targets Matthew rather than its originator.
- In Thursday Next, Thursday's adventures eventually inspire a book series, with the books' interpretations of Thursday appearing in the fictional Bookworld. The Thursday of the first four books is a leather-wearing pastiche of Badass Anti-Hero cliches, who eventually just decides to turn evil. Interestingly, after these four books the writers decided to go in the opposite direction so there's also a Thursday who's a touchy-feely Granola Girl. This gives the impression that she's become a Literal Split Personality, except that the real Thursday is still around and is demonstrably the only one from the Real World.
- A portion of Brave Story involves this trope. It becomes crucial in the climax.
- Spock gets an "evil version" in Spock Must Die. It's caused by — yes, you guessed it, a transporter accident.
- The Dark Half, by Stephen King: The protagonist, an author, is persecuted by his pen name, which has come to life as an independent individual after being given a mock "funeral." Apparently the pen-name persona has created its physical form from a rudimentary conjoined twin that was removed from the protagonist's body in childhood. King was inspired to write this novel by his experience with his own pen name, Richard Bachman.
- In the Russian adaptation of "The Shadow" story, written by E. Schwartz, the protagonists's shadow becomes this. It is repeatedly shown that the hero and his shadow share abilities, but use them differently.
- Averted (somewhat), but this was at least part of the motivation for Dr. Jekyll. He hoped that he could divide a person's good and bad sides, and let each one go free to its own devices, letting both of them do what they do best and each to be happy. It didn't work out that well, leading only to Hyde's malevolent persona and a physical transformation. Ironically, this, including the fact that Jekyll and Hyde were one person, was supposed to be all revealed as a twist in the end.
- In The Separation of Animorphs, Rachel has a Starfish Character episode, where she's split into two halves, dubbed "Nice Rachel" and "Mean Rachel." Mean Rachel is widely regarded as the "enemy" of the "Enemy Without." Subverted when, eventually, Rachel (along with everyone else) realizes that both halves are needed. Played straight because, for the rest of the series, Rachel recognizes that darker part of herself, and does not like it.
- An odd example is in Ex-Heroes. The hero known as Cairax is really a demon, and when he returns in the third book, the human who had merged with him splits apart, and acts to destroy him.
- "William Wilson" by Edgar Allan Poe has an interesting twist on this idea. The narrator is a complete Jerk Ass, and the story describes his torment as his schemes are frequently thwarted by another person identical to him, even down to having the same name. It turns out that this second character is the personification of his conscience, whom he murders at the end of the story.
- A short story by Bruce Coville called "The Japanese Mirror" has this. The protagonist finds a strange mirror which absorbs his anger. At first, he sees nothing wrong with this as it seems to fix his anger issues. But as he becomes thinner and thinner, he finds out that a darker copy of him is lurking in the mirror, feeding off his anger and waiting to take over his body.
- In Exalted, the Ebon Dragon Charm called Black Mirror Shintai allows the user to become the victim's Enemy Without. Their victim's shadow disappears, and the user becomes an exact copy of them in all ways except one: their Motivation is a perfect inversion of their victim's, being devoted to undermining their goals and tearing down whatever they hold most dear.
- And in Fading Suns, this is what happens if a psychic behaves very badly.
- New World of Darkness
- In Mage: The Awakening, it is possible (although not wise) for a mage to bring some aspect of his personality (usually his personal Vice) into reality in a physical body. Doing so frees the mage of that personality aspect, but having a mage's Pride or Wrath walking around doing stuff isn't usually a good thing.
- Similarly, Vampire: The Requiem introduced the idea of "Hollow" Embraces — vampires who were Embraced post-mortem. They have the traditional vampiric trait of not having any reflection and not appearing on film, whereas other vampires just show up blurry. Thing is, that reflection is now a separate being. And it hates them.
- Before it was retconned as a part of the Ravenloft setting, the 1st edition AD&D module I10: The House on Gryphon Hill was a stand-alone adventure in which the vampire Strahd von Zarovich was the Enemy Without of a benign alchemist with the same name.
- There is a D&D item called the mirror of opposition. It's basically a magical trap: if you look in the mirror, it will create an Enemy Without of your own level and carrying similar equipment, but with an alignment opposing yours. Since characters of directly opposed alignment have very different morals and worldviews, they will likely initiate combat right away.
- Vezon is this for Vezok in BIONICLE. They're both evil, (mostly), it's just that one has very good tactical thinking abilities, and the other one has sanity. An unusual variation of this trope is that Vezon, the duplicate, is now acknowledged as a character in his own right, and has actually surpassed the original in terms of popularity.
- The original story plans (that were ignored by Cathy Hapka when she wrote Tale of the Toa, though later Retconned into canon by the BIONICLE Encyclopedia) for the defeat of the Shadow Toa was essentially this trope in reverse. The only way the Toa Mata could defeat the Shadow Toa was by accepting the Shadow Toa as manifestations of their own inner darkness, and thereby absorbing the Shadow Toa into their bodies.
- Nanaya Shiki in Tsukihime: Melty Blood. Though, in a sense, he can be considered a form of alternate "what if" version of Tohno Shiki.
- Or what Shiki thinks is an alternate "what if" version of him. Also from the same game series: Red Arcueid (Arcueid falling to her bloodlust), and White Len (a jerk mirrored version of Len). Akiha Vermillion and Sion TATARI look like this, but actually aren't, Vermillion being Akiha's Super-Powered Evil Side (but not really that evil) and Sion TATARI as an alternate fate of Sion. However, this trope does sort of apply to Dust of Osiris, who is an alternate Sion from a potential future. And finally, the Night of Wallachia/TATARI can become/create this.
- Umineko no Naku Koro ni:
- In the third arc, Eva's younger-self "Imaginary Friend" becomes the new Endless Witch, and sets about murdering her entire family in the most cruel and unusual ways she can think of, apparently over Eva's protests. She's actually an Anthropomorphic Personification of theories that place Eva as the culprit.
- More broadly speaking, Bernkastel is this for Rika, from its predecessor, Higurashi no Naku Koro ni. It turns out that the events of Saikoroshi-hen purged her from Rika's consciousness. She is, in essence, the embodiment of all of the dead Rikas who never made it past June of 1983. She doesn't actually rampage around in her source's world, however, instead making trouble in other worlds simply for her own amusement.
- The Fighting Game Ougon Musou Kyoku Cross introduces Black Battler, who is the Anthropomorphic Personification of the idea that Battler is the culprit.
- An interesting variation is found in 8-Bit Theater, where during the main characters' trip into the Castle Of Ordeals, the only thing evil enough on the Castle's record to represent Black Mage's sins is... himself, who becomes more powerful as Black Mage reminds the doppelgänger of a few serious sins the Castle forgot to add. In typical fashion, Black Mage gets the manifestation to let its guard down, then stabs its face... from behind. Then absorbs its evil energy to avoid the catharsis of killing his own evil. Then commits one last atrocity offscreen, implied to be sex with the corpse.
- In The Wotch, Anne once tries to create helper duplicates, and is Genre Savvy enough to make sure none of them believe they're the original or decide they'd rather stay separate. Something goes wrong with it anyway, and each copy is a different aspect of her personality (often simply wearing a different color, though a few take on forms from previous arcs, such as her courage being a Batgirl-based hero, and her curiosity being a Cat Girl.) The villains talked her anger, frustrated with having been kept from acting by the rest of Anne's personality, into refusing to return and trying to get rid of the others.
- After a crossover with Melonpool, It's Walky! introduced Anti-Joyce, a slutty duplicate of Joyce supposedly created from her repressed libido via the Dupe-O-Matic. She was killed by the original shortly afterward.
- Misfile: The Wraith in the Aiden and Bronwyn arc was a projection of the negative parts of her love. Maybe.
- The exact nature of Xero in Suicide for Hire isn't quite clear, though he's definitely spawned from Arcturus' dark side. Arcturus describes arm-wrestling with Xero as a "metaphorical battle", implying it's taking place only in his imagination, and nobody else can see Xero, but Arcturus holds conversations with him out loud (much to the confusion of the waitress who sees him talking to himself and can't hear the replies). The strongest evidence that Xero has some kind of tangible form is that items of clothing Xero was seen wearing, which Arcturus doesn't own, keep turning up in places he's recently been.
- Subverted to hilarious effect in Rusty and Co. when Madeline the Paladin gets zapped by an artifact that draws out her evil side, Anti-Madeline — who turns out to be about two inches tall.
- White Dark Life has shadows, the dark half of a neutral soul. The most notable is Dark Matt, the Shadow of one of the main protagonists, while antagonistic he is in secret, very self loathing and envious of the protagonists.
- This was attempted in Survival of the Fittest version two, but didn't work out. The character Walter Smith was originally made in the pregame with the concept of him being the manifestation of Jack Bexley's dark side, as Jack was also a politician's child but, while he did not let himself be corrupted as Walter was, still had part of him that was like that. The plan was that they'd be bitter rivals, and Jack would eventually kill Walter in a fight late in the game as a symbol of finally getting rid of that side of his personality. Unfortunately, Jack's handler left the site and never put Jack into the game, leaving the storyline in the air and Walter as a pure evil villain without any of the symbolism.
- In The Spoony Experiment, Doctor Insano (pictured above) is an ambiguous example of this. It hasn't been made clear if he's a clone, Spoony's future self, or from an alternate dimension. Kickassia made it canon that Insano is part of a split personality Spoony has, which makes no sense in context of every other appearance Insano made.
- Atop the Fourth Wall has a peculiar variation. Linkara goes on a quest of sorts, and leaves behind a Star Trek-esque hologram with his personality. At the end of his journey, Linkara discovers that he had been slowly becoming evil; that is to say, he'd become aggressive, arrogant, uncaring, and using force to achieve self centred goals. On the way back home, he resolves to better himself and be a good person. The hologram, however, has no such character development, and while fairly affable in most conversation, he threatens the lives of Linkara's friends, and devises a plan to blackmail Marvel into writing better comics. Naturally, when Linkara gets home, he deals with the thuggish version of himself face to face.
- Happy Tree Friends: Flippy vs. Fliqpy in "Double Whammy". It ends up being a subversion, however...it actually is a case of Enemy Within and simply appeared to be Enemy Without to both Flippy and the viewer.
- In Jackie Chan Adventures, this happens a few times with the Tiger Talisman (namely to Jackie), which can split a person's yin and yang sides into separate beings that act independently until they are fused together again. Notable, however, in that Jackie's dark side, while rude and prone to violence, is NOT evil, just incomplete without his light half, and is more interested in what he thinks is "cool".
- In Ben 10, Ben's Ghostfreak form is revealed near the end of the second season to be bad news... After Ben loses control, Ghostfreak winds up separated from Ben's body and on his own, chasing Ben and possessing others for the remainder of the episode, trying to get back to Ben's body and take over. One of the examples where "re-integrating" the Enemy Without would be a very bad idea.
- Then again, near the end of the third season, a copy of the "true" (sunlight-vulnerable) Ghostfreak ends up on the Omnitrix. Whether this copy contained Ghostfreak's personality was never shown.
- Well, Ghostfreak himself said that his race, the Ectonurites, retain memory within the tiniest strand of DNA, so, yeah, it's probable that this is true, and that the writers just forgot.
- In Samurai Jack, Aku realizes that none of his forces are as strong as Jack is... so he creates an Evil Twin of Jack, made of Jack's anger and fury, to take him out. Naturally, Jack wins when he accepts it and doesn't fight back.
- In Darkwing Duck, the first episode ever written with a character called "Negaduck" was not truly starring the recurring Evil Twin Alternate Universe Negaduck that came to spearhead the Fearsome Five in later days. This Negaduck was the accidental byproduct of an invention Megavolt called "the tron-splitter", which was designed to separate an object into its component "positrons and negatrons", and then later re-merge them. A locked door, thus separated, would leave an empty doorway Megavolt could simply stroll through, and once re-merged without ever being unlocked, there would be no sign of tampering for the CSI squad to analyze. Things start going wrong when Darkwing catches him red-handed, and in the ensuing fight, Megavolt turns the tron-splitter on DW. DW's good side turns out, much like Captain Kirk, to lack the necessary sock-pow forthrightness that makes for a quack-fu action hero, while his evil side is unhesitatingly violent, and goes on a fearsome rampage. Later, it is discovered that the tron-splitter can "galvanize" a tron-pure subject, imparting functionally limitless super powers. As always, the solution is to re-merge the two before the Enemy Without destroys everything. Also includes an instance of Spot the Imposter, early on after the split.
- As implied, this is all a comedic rehash of an episode of the original Star Trek in which a transporter accident splits Captain Kirk in two.
- In Justice League Unlimited's third season, Shadow Thief was revealed to be Hawkman's Enemy Without.
- In the South Park episode "Fourth Grade," Mr. Garrison has a face-off with his "Gay Side" in a direct parody of the cave in The Empire Strikes Back. He loses.
- In an alternate Bad Future of Danny Phantom, after losing his entire family and friends to a deadly explosion, the main character willingly agrees to separate his humanity. Thus resulting in his sympathetic arch enemy Vlad Masters—who had just recently adopted Danny—to honor his wishes by using the Ghost Gauntlets to separate his ghost half from his human self. This doesn't turn out so well; his ghost half instantly turns malevolent, uses the same procedure to tear off Vlad's ghost half, and joins with his half. The result? A Carnage-like mixture of Vlad Plasmius and Danny Phantom: Dark Danny. Not only does he kill his human half, but he blows up the entire mansion, and spends the next ten years turning the planet into a living nightmare. And this is a kid's cartoon.
- Teen Titans: This happens in multiple ways to all the Titans: Starfire, Cyborg and Beast Boy fight against the physical manifestations of their own evil, Raven confronts a case of Enemy Within in her dreamscape, and Robin fights a hallucination of his Shadow Archetype Slade that his own mind made up under the influence of a very, very bad trip.
- The Legend of Korra has Dark Avatar Korra, a manifestation of Korra in the Avatar State during her battle with Zaheer.
