"Now, I don't want to give anything away here, but one of these guys is going to be the villain. Can you guess who?"A Face–Heel Turn or someone Evil All Along that was obviously coming. This character is supposedly one of the good guys, but they have a certain air about them. You just know that they'll eventually betray the group in some way or another, even though the writer has shown no evidence that they plan to actually do evil (rather than just look evil). So why suspect them? They express traits that seem Obviously Evil; perhaps they speak in a Creepy Monotone and wear an Ominous Opera Cape, or thier name is "Mordred McTraitor", or they just look like a Dastardly Whiplash. When they finally turn evil, you say, "I Knew It!!" This trope is an Audience Reaction, because the other protagonists suspect nothing. This trope can also happen in universe if a character predicts a betrayal, but doesn't warn the good guys. This trope can become The Untwist, if the audience thinks (by mistake) that the character can't turn evil, because it would be too obvious. It can overlap with Narrowed It Down to the Guy I Recognize, if one protagonist's actor usually plays evil characters. Do not add an example until the work reveals that the character turns evil. The audience might see an Obvious Judas where the author did not intend one. It would be stupid to list someone as an Obvious Judas, only to reach the end of the story and find that the character never became a Judas. Examples for characters, who aren't evil yet, belong in Wild Mass Guessing. Also beware of hindsight: anyone can predict a Face–Heel Turn after it already happened. This trope only counts if the character seemed evil back when he or she was outwardly good. Judas Iscariot doesn't fit this trope in The Bible (though he did betray Jesus), but Judas might fit this trope in newer works that retell biblical events, and other characters might fit this trope if the audience sees an allusion to Judas. Often can come across as rather insulting. However, Tropes Are Not Bad: occasionally this trope can intentionally be used as a Red Herring, such as when the obvious traitor turns out to be The Dragon to a not-so-obvious one. Subtrope of Captain Obvious Reveal. Related to Devil in Plain Sight, though this requires that a character is deliberately portrayed as obviously untrustworthy and that another character picks up on this. THERE ARE SPOILERS AHEAD... but considering what the trope is about, they're pretty obvious ones.

Anime & Manga
- Bleach: Many readers were suspicious of Aizen long before he was revealed as the Big Bad due to the fact he was playing the stereotypical role of the too-nice character that's deeply concerned about a potential conspiracy, who confronts the apparent villain and gets killed off shortly afterwards. Aizen's reveal was therefore fully expected rather than surprising.
- Vegeta in the Majin Buu arc of Dragon Ball Z. Double Subversion. Due to everyone knowing he's a giant Jerkass, and still pretty evil, and making more than his normal "evil" behavior during this specific time, he was expected to do this. The subversion is that it appears he was FORCED into his Face–Heel Turn, then the other comes from that he used a rather elaborate Batman Gambit to get Babadi to target him, thus making him a Judas in the sense of the trope.
- Defied: Hiei from YuYu Hakusho. Everyone except Yusuke believed that he would betray the group during the Saint Beasts arc, however this proved not to be the case once the demon tells the Saint Beasts to go to hell.
- Yusuke's trust had a weird effect on Hiei. Later, in the Chapter Black arc everyone is startled when Hiei goes 'stop the tunnel to Demon World? Screw that, I want to go home,' and ditches the rest of the team. He comes back and saves Yusuke's life less than a week later, though. And then he and Hiei beat the snot out of each other for a while, and then they're friends again. Even after the team splits up.
- Kai from Beyblade. He barely tolerated his teammates, and gave off the impression that they were beneath him and his talent. The only thing that makes his teammates' shock at his betrayal remotely believable is that such a low, petty thing as stabbing them in the back in exchange for being given power seems strange coming from someone as openly confrontational, arrogant and self-reliant as Kai.
- Dennis Macfield of Yugioh Arc V. He pretty much pops out of nowhere and latches on to Yuya, seemingly fits into Yuya's group perfectly despite just meeting them, gives off a creepy vibe to Yuzu, and hides his ability to use Fusion for seemingly no reason. (Fusion used by the main antagonist group, Academia, though anybody on either side can use it if they learn how.) Surprise surprise, he actually works for Academia and was sent to capture Yuzu and/or infiltrate the good guys' team.
- This is also parodied when he and Gongenzaka have a duel in front of an audience. Dennis plays the Face and forces Gongenzaka to be the Heel. The audience believes Dennis despite his attitude, until Gongenzaka pointing out that Dennis's behavior is clearly indicative of the villain; afterwards, Dennis plays the Heel of the duel.
- Ren Gyokuen from Magi – Labyrinth of Magic. Back in Alma Torran, how could King Solomon have ever possibly foreseen his betrayal at her hands, given how she's portrayed in flashbacks as a shady figure with a winged staff, creepy Empty Eyes, and couldn't be any more Obviously Evil if she tried? That's because the person we're seeing is not the traitor Gyokuen, but Solomon's future wife Sheba, who looked like that from a lifetime of Break the Cutie but eventually recovered. Gyokuen is actually Arba, the Magi who always portrayed herself as Solomon's faithful follower and mother figure and didn't show her true colors until Solomon decided to become the new god of Alma Torran. Gyokuen has the same staff as Sheba because Arba stole it after killing Sheba.
- Sigurd from Sword Art Online. He pushes Leafa around, even outside the terms of their original agreement, and when Kirito intercedes on her behalf, Sigurd threatens to kill him while Kirito is unable to fight back due to being in an enemy city (in ALO, death doesn't kill the player, but since it has an apparently steep EXP penalty, this is quite a Kick the Dog moment), only stopping when his underlings point out that there are people watching. It's thus fairly obvious that he's the traitor to the Sylphs, although the twist is more about the existence of one, rather than the traitor's identity.
- Paintings of the Last Supper depict Christ and all the Apostles with big shiny halos... except for one guy at the table.
- In his very first appearance X-Men villain Fabian Cortez betrays all his allies, including Magneto and his own sister, making him this in every appearance thereafter.
- No matter if a good guy or a bad guy, any comic that tries to treat Loki's inevitable betrayal as a twist (for example A-Force) will inevitably fall into this category.
- In White Sand, Drile's Establishing Character Moment comes when he's trying to sell his skills for money and is subsequently demoted from top rank to the middle. When it turns out he's survived the massacre of the Sand Masters, it doesn't take a genius to figure out who was Kerztians' inside man.
- Played for Laughs in Ghostopolis when the protagonists run into the ghost of Benedict Arnold; there's maybe a fraction of a second where it looks like he'll help them, than he immediately sells them out to the villains while standing right next to them. Towards the end of the book they run into him again and Frank makes sure to call him a jerk, to which Benedict says "sorry, but it's in my nature!".
- Trixie, in Rainbooms and Royalty. She's a huge jerk to just about everyone except Dash, so it's little surprise when she starts actively trying to mess with the Ponyville ponies.
- The version of Judas Iscariot in the Empath: The Luckiest Smurf story "Smurfed Behind: The Passion Of The Smurfs" is a little too obvious if he happens to be related somehow to the Smurfs' main enemy Gargamel.
Films — Animation
- In the 1954 adaptation of Animal Farm, the design of Napoleon makes it far too evident that he is or will become the bad guy, especially if you compare him with the other pigs.
- Titan A.E. has Preed, the resident Jerkass and Deadpan Snarker who the rest of the crew can barely stand, and at one point was more interested in shooting grasshoppers than keeping a look out for The Drej. The fact that he turned out to be The Mole surprises no one.
Films — Live-Action
- Harry Osborne from the Spider-Man Trilogy. He was pretty much set up solely for the purpose of being Peter's Judas (starting with hitting on Mary Jane and starting to date her, the implication being that he wanted Peter to be jealous of him like he was jealous of his dad's affection for Peter).
- Magneto in X-Men: First Class. Conflicting views with Charles and his traumatic experiences at the hands of the Nazis makes it obvious even to those who don't know the entire X-Men story that he has a major chip on his shoulder towards humanity and will eventually betray Xavier. Although a good reason for this is that the movie is a prequel, making the split between himself and Charles a Foregone Conclusion.
- One review of The Fellowship of the Ring mentioned "If I were Frodo, and Boromir had been this obvious about his intentions, I'd have been off on my own before the Fellowship reached Moria."
- Cypher in The Matrix has a shifty vibe from the beginning, solidified when he tells Neo, "Why oh why didn't I take the blue pill?"
- A forgone conclusion in the Star Wars prequels, but as early as Episode II, Anakin Skywalker was wearing dark robes as a contrast to the light brown ones of his mentor Obi-Wan Kenobi, as well as almost every other Jedi that appears. He's also more angry and impulsive than the other Jedi (something which is repeatedly pointed out), and by the end of Episode II, has broken almost every part of the Jedi code by slaughtering a village full of innocents and getting married. If you were surprised that he became Darth Vader at the end of Episode III, aside from the Popcultural Osmosis Failure, you had missed some pretty obvious foreshadowing.
- In The Last Hero the character of "Evil" Harry Dread proudly wears this as his hat, and even reminds the party that he is evil and therefore contractually obliged to betray them at some point. The heroes accept this as part of the Heroic Code and even congratulate him on a job well done when he does betray them.
- The Harry Potter novels subvert this trope. Severus Snape is Harry's least favorite teacher. Harry Potter and the Goblet of Fire reveals that Snape is a former Death Eater. Other Death Eaters are returning to the evil Voldemort. The Face–Heel Turn happens in Harry Potter and the Half-Blood Prince, when Snape murders Dumbledore. At this point, Snape is an Obvious Judas. The final reveal in Harry Potter and the Deathly Hallows shows that Snape was only a Reverse Mole spying on Voldemort, and had given a Mercy Kill to Dumbledore who was Secretly Dying due to an unbreakable death curse on one of Voldemort's Horcruxes.
- A Song of Ice and Fire:
- For the North Roose Bolton. He's on the "good" side of the Starks, but comes from a long-time rival of House Stark that still brags about how they would flay their enemies alive, and even has the flayed man as their sigil, along with living in the Dreadfort. He's also constantly described as creepy, being very pale and having a quiet, whispered voice due to his frequent leechings (even holding a meeting while naked and being leeched), and has a number of weird habits.
- The Freys have the reputation of being up-jumped, self-important and loyal only when it suits them. This reputation was galvanized when they obeyed their oath of loyalty to the Tullys during Robert's Rebellion only after it became clear that the Tullys were going to win anyway. Also, most of the Freys are described as very unattractive, many reassembling their weasel-like common ancestor, Lord Walder Frey. Also many of them are very unpleasant, from the abrupt and rude "Bastard" Walder Rivers, the thuggish and fierce Hosteen Frey, the scheming "Lame" Lothar Frey, and the brutal "Black" Walder Frey. The trope is confirmed when Walder switches sides against the Tullys and Starks, and then has them slaughtered. Ironically, some of the nicer Freys, such as Roslin, are described as being relatively attractive.
- Littlefinger plays with this by being so obviously up to no good that people write him off as either a Sarcastic Devotee or a Smug Snake with a blatantly obvious (and thus easily foreseeable) case of Chronic Backstabbing Disorder, rather than a full-fledged Magnificent Bastard who excels at inducing wrong genre savviness in those around him until precisely the right moment.
- A strange sort of subversion in Merlin. That Mordred will one day kill Arthur is a Foregone Conclusion, one that Merlin learns about as early as the first series. By the time an adult Mordred reappears in the fifth series, Merlin is nearly beside himself with paranoia, certain that the young knight is playing some sort of long con to get in good with King Arthur before betraying him. As it turns out Mordred is completely genuine in his loyalty and affection for Arthur and all his creepy behaviour and ominous looks are just incidental. His betrayal comes when Arthur has his Childhood Sweetheart executed for treason, thus leading Mordred on an arguably justified (to some degree) Roaring Rampage of Revenge.
- Played for Laughs in the series finale of Angel.
Angel: I know this is going to sound pretentious, but one of you is going to betray me tonight.
Spike: [raises hand] Ooh! That's me!
Spike: Aw. Can I at least deny you 3 times?
- NTSF:SD:SUV::: Parodied and Double Subverted in an episode where Robert Picardo shows up playing a creepy, sinister tech expert who just so happens to have shown up after "the mysterious untimely death of the previous tech expert". Nobody except Sam seems to notice his suspicious behavior (like making headless dolls of the entire team), who later confronts him about it and is immediately proven wrong when the guy acts shocked at the suggestion and it turns out he is Not Evil, Just Misunderstood. Then the final scene shows that he and Agent Trent were both behind the episode's plot.
Myths & Religion
- Judas Iscariot himself, as the Gospel of John mentioned that he was a thief and a hypocrite even before his betrayal (in one case, Mary the sister of Martha anointed Jesus's feet with expensive perfume, and Judas complained that they could've instead sold it and used the money to feed the poor, though since he regularly stole from the apostles' funds philanthropy probably wasn't his actual motive).
- Jesus Christ Superstar: Judas, duh. The 2000 has him as the only follower that wears dark clothes or leather, and one of his first interactions with Jesus has him insult Magdalene for her...profession.
- In The Bible: The Complete Word of God (abridged), Judas himself is acted with an evil Peter Lorre accent in the Last Supper sketch.
- Kreia from Knights of the Old Republic II: The Sith Lords. She comes across like a Sith Lord, admits to having been one, constantly manipulates and mentally tortures your companions, and acts as arrogant and pompous as any of the Sith. Not to mention, her (and the writers') attempts at deconstructing the Black and White Morality of the Star Wars universe almost always result in acting like a heartless bastard (and Dark Side points).
- Cait Sith from Final Fantasy VII. He's a talking cat with a superiority complex and an Irish accent. What part of that doesn't say "trouble"? Then again, the person controlling him is Shinra's Token Good Teammate, who eventually turns on them and joins AVALANCHE for real.
- This was another example of FF 7 Playing the audience. Cait Sith was a pretty obvious attempt at a Mascot Character that are often found in Japanese Media. Typically, these characters are not meant to be taken seriously. They are there to look cute and provide Comic Relief; Sometimes they have a mischievous streak, but it never causes any real harm. That Cait was such a blatant attempt, and not a very likable one at that, no one paid much attention to him even when the clues started stacking up. Thus when he was revealed to be The Mole, a competent one at that, and had surprisingly deep characterization was a real shock. This was, however, lost on most Western audiences since (at the time) they weren't familiar with the cultural trend; not helped by the fact most Westerners tend to find mascot charters annoying.
- Bishop and Qara from Neverwinter Nights 2. One's a Social Darwinist who practically screams "don't trust me!", and the other's a sociopath who hates being one-upped, which The Hero frequently will. Do the math yourself. Surprisingly, though, this can be somewhat subverted; while Bishop will always sell you out, he can be persuaded not to fight you if you're female, and while Qara will almost always betray you, there's a slim chance she won't.
- You can easily plan for maintaining Qara's loyalty if given the simple piece of info that whoever is more loyal of Sand and Qara will stay with you and the other will betray you. If that's your thing. Pissing off Sand was not something most players did, as he's both plot-relevant and one of the more likeable characters.
- Orson in Fire Emblem: The Sacred Stones is introduced to us after a scene where Tirado, right-hand man of Smug Snake Valter, mentions having a traitor in Prince Ephraim's force. He also spends large amounts of time away from the party and has a goatee. The numbers add up quickly against him.
- Similarly, shortly after Nasir joins the group in Fire Emblem Path of Radiance, we see Big Bad Ashnard mention that there's a traitor in Ike's ranks. Nasir has a unique design, but isn't playable, which should instantly tip players off that something is wrong. Soren, the group's tactician, even confronts Nasir about it early on. Unlike the above example though, Nasir turns out to have sympathetic motives, and if the right conditions are met he makes a Heel–Face Turn near the end of the game and does become playable.
- Zola in the Birthright route of Fire Emblem Fates looks as Obviously Evil as they come and is another example of "joins the group but isn't playable". Everyone remains suspicious of him from the moment he joins, and sure enough, he's a Heel–Face Mole. It's played with, however, in that Zola genuinely came to sympathize with the party while he was with them and pleads with Garon to spare them, which gets him killed.
- On the Revelation route, it becomes clear that there's a traitor in the party in the last act. The fact that Gunter can't support with anyone on this route makes him very suspicious, and sure enough, it's him.
- Fire Emblem also frequently inverts this trope, as Awkward Zombie pointed out, featuring enemies who are better-looking than their comrades, have their own name, design, and class, and are shown doubting the cause and acting friendly in the pre-level cutscene. Nine times out of ten, they're recruitable, and will join your side with nary a backward glance if the right person talks to them. This in itself has led to the Camus archetype - a character who meets all the above criteria, and then turns you down.
- Dragon Age: Origins subverts this by how quickly the villains turn; so soon that their reveals doesn't get a chance to become a spoiler. If playing the Human Noble background first, Arl Howe might surprise you in the introduction, otherwise he's already obviously evil the first time he's seen. Loghain commits his betrayal and heads for coup at the end of the first Act, and the first time we see him his pale, cadaverous look screams Obviously Evil (although the "evil" part turns out to be a case of Well-Intentioned Extremist who's overestimated his own capabilities).
- If you fail to gain enough loyalty Zevran will turn on you as soon as he's given a chance to return to his previous life with the slate wiped clean of his initial failure. This is after he's spent the game playing up how shallow, self-interested and jovially merciless he is.
- Jeanne d'Arc has Gilles, a very pale, dark-eyed, and overall somewhat sinister-looking nobleman who joins Jeanne's cause. He's so polite and supportive of Jeanne that it feels like he must be up to something. And for anyone who knows their history, he's obviously Gilles de Rais, a compatriot of the real Joan of Arc who, some time after her death, was tried and convicted as a molester and serial killer of young children who had also attempted to summon a demon. By the way, the game involves a secret war against demons behind the real war between France and England... Defied in the game as Gilles turns out to be perfectly heroic and loyal throughout. However, he does in the end become the can in which the evil is sealed in hopes of smothering it to death under his heroic spirit, which could mean the demon got the better of him in the end.
- Breath of Fire: Dragon Quarter: Bosch. He may be your best friend, but it's obvious, due to his smug, aristocratic manner and the the way his ego is tied to his D-Ratio, that he's going to betray Ryu the moment Ryu bonds with the most powerful dragon in the land, (thus proving that the all-important D-Ratio has nothing to do with the greatness of one's destiny.)
- Tales Series
- Tales of the Abyss: The first half of the game does a good job at hiding the potential mole in your party. It's during the second half, when suddenly all curtains are raised and an arrow points at Anise, including her utterly exaggerated reactions to things or mysterious disappearances, along with the fact that her parents are in debt to the Order of Lorelei, so Mohs has leverage against her. According to some players, Anise being the mole felt like an Ass Pull.
- Tales of Xillia: In the series in general, everyone expects one traitor per game, but Alvin vin Svent takes this Up to 11. Not only is he a very suspicious mercenary who very conveniently bails Jude and Milla out of getting arrested, he betrays the party constantly (not kidding, it was at least eight times). The party justifies keeping him around by saying he'd follow them anyways and at least this way they can keep an eye on him, but it's a surprise no one just kills him with all the trouble and grief he causes.
- Tales of Symphonia: After Kratos, who was a mercenary with suspiciously varied knowledge in all sorts of aspects of the world of Sylvarant (See where Alvin got it from?), betrays you, the player can easily tell the next one coming. It's no surprise when it turns out that Zelos is the next traitor in the group. He disappears at times, has convenient excuses or explanations for things. His Obfuscating Stupidity didn't fool any player for every long, either.
- One of the factors to how obviously the Traitor character in any given Tales game will be portrayed comes down to Idealistic vs. Pragmatic spread among the party members; and Tales of Vesperia is no exception. Raven betrays the party once or twice before he even formally introduces himself to them. When he does join, he shamelessly does so by exploiting their need for information he has after they make it clear they don't trust him. While the revelation of his true identity as Captain Schwann seems to catch everyone by surprise, only Karel and Rita seem genuinely surprised by his betrayal, whereas the more experienced Yuri and Judith seem to have anticipated his inevitable betrayal.
- Nuzleaf of Pokémon Super Mystery Dungeon has gotten this reaction from quite an amount of players. He acts pleasant enough with the heroes, but the series has a tradition of making the overtly nice ones Evil All Along. He also seems a little too interested in the player character's amnesia and Serenity Villages's high security area...
- Lysandre from Pokémon X and Y has so many tip offs and Obviously Evil tropes stapled onto him. Between his intimidating character design, red (specifically Team Flare red) and black color scheme, ominous Leitmotif, tendency to go on Motive Rants over the fate of the world (along with calling people "filth"), and the fact that Team Flare members openly congregate at his cafe, the only people surprised that he was the Big Bad were characters in-game... this includes the region's professor and Champion, both of whom he's openly given villainous monologues to.
- The Aether Foundation, specifically Lusamine from Pokémon Sun and Moon suffers from this to an even greater extent thanks to having much of its plot revealed in marketing. In their debut trailer, the Aether Foundation appeared to be a group of Motherly Scientists dressed in gold and white who run a conservation group for Pokemon that were hurt by Team Skull. Of course, people quickly got Light Is Not Good and Pure Is Not Good vibes from them when they saw that their "branch chiefs" and "employees" were basically grunts and admins in disguise. Within the game itself, the opening sequence features Lillie running away from Aether Employees, and their formal introduction includes a number of Obviously Evil tropes, raising the question of why the marketing even tried to pass them off as good guys. A twist still exists in that Lusamine's research with Ultra Beasts has made her Brainwashed and Crazy, and that Admin Faba is the only actual sinister member of the organization (with the post-game of Pokémon Ultra Sun and Moon emphasizing both these points even more), though.
- Not helped by the fact that Team Skull, a group of Large Ham goofballs mostly involved in petty crime who nobody took seriously in-game, were the ones advertised as the supposed actual villain team of the story. Due to the series' Plot Leveling of having the villainous teams becoming more and more dangerous which each new installment, to the point that the entire world was usually at stake by the end of the game, everyone correctly pegged them as decoy antagonists meant to hide the real villains.
- In World of Warcraft, during one Alliance quest in Spires of Arak, the traitor who was selling plans to the Horde turns out to be a drunk with a history of disciplinary problems, meaning he clearly wasn't even pretending to be a model soldier.
- In Persona 5, it's learned at the beginning that someone betrayed the party, but not said who. For a variety of reasons, it's fairly obvious that it's Goro Akechi, and in a unique twist on this, it's eventually revealed that the party was entirely aware of their being a mole from the beginning while the game is deliberately misdirecting the player, leading to dueling Gambit Roulettes from both the traitor and the party.
- In Ultima V, who would have suspected that Saduj was secretly plotting against you?
- This Chuckle-A-Duck comic features Judas Iscariot himself as a Dastardly Whiplash.
- Eridan Ampora from Homestuck who was near-immediately established as a genocidal orphaner with a love of gunplay. Almost all of his darker traits were quickly overshadowed by his pathetic love life, though anyone who remembered his original introduction probably expected his turn to evil the instant his various romances were sunk.
- Subverted in Darths & Droids. Jim, who is playing Qui-Gon Jinn, is convinced Sio Bibble is this since he has a goatee and is an advisor to the queen which means he must be an Evil Chancellor. He wasn't.
- Mega Man Dissonance: Readers have suspected that Dr. Hook might actually know more than she lets on and be behind everything. Come chapter 11, and lo and behold, she's involved with Requiem's plan.
- When the term "pre-made psycho" or similar is used among Survival of the Fittest handlers, it's generally a reference to this. It's used when a character is clearly going to play the game the second they get on the island just from a read-through of their profile. It often includes any mixture of sociopathy, Dark and Troubled Past, prior firearm or martial arts knowledge, mental instability, or excellent manipulation skills. While more common in earlier versions, the staff nowadays tries to avert this by requesting profiles that have clear pre-made traits to be rewritten if not outright denied.
- South Park:
- Cartman is the Token Evil Teammate. Even in a reference to the last supper, Kyle believes someone will betray him. Cartman (who has already betrayed him) makes an outbursts that anyone that would betray Kyle is a loser. Through the rest of Kyle's speech, he is giving Cartman a Death Glare.
- Also parodied in the Wal-Mart episode, where the boys are reluctant to bring Cartman with them on their trip to Wal-Mart because they know he's going to betray them. Cartman is even offended when they say they saw his betrayal coming, and claims that they're just lying. Kyle even says he saw him impeding their progress but Stan and Kenny don't care since Cartman is inept at betrayal so they don't have time to make sure he won't join them.
- Sinedd from Galactik Football, he was arrogant and very distant from the Snow Kids.
- Subverted in The Legend of Korra. Asami is incredibly obviously secretly evil; her beauty, having paler, sharper features than the heroine and being more traditionally feminine, wealth, red and black clothing, striking up a relationship with the guy Korra's interested in, and being the daughter of their enemy's Evil Genius accomplice all mark her as the person who turns out to be evil to the shock of the characters but not the audience. In fact she's nothing of the sort, and remains one of the most noble characters in the show. Apparently in the early stages the writers planned for her to be an Equalist spy, and when they changed their minds saw no reason to change her character design. Even more subverted in the last season, where she becomes Korra's Love Interest.
- Bismuth of Steven Universe is introduced as an old war comrade and friend of Garnet and Pearl, but savvy fans suspected something amiss given that Bismuth had been bubbled and left in Lion's mane, inaccessible to the rest of the team, so assumed that she was shattered in the war. She also fits in a little too perfectly with the main team in a show [[that generally doesn't give such characters much screen time. Ultimately downplayed in that she's revealed to be a Well-Intentioned Extremist instead, whose disagreements with Rose Quartz (and eventually Steven) over Bismuth creating a weapon capable of easily murdering their enemies ended up becoming physical. Her episode ended with Steven leaving a better impression on Bismuth than Rose Quartz had, and her being bubbled once more. Word of God says that the character will eventually return.
- Ben 10: Omniverse:
- In Frogs of War, La Résistance against the Inkursean invaders is made of Gwen Tennyson, Kevin Levin, Rook, Blucik, and... Argit. One guess on who ends up being The Mole.
- A special mention goes to Dr. Viktor for being a rare Heel–Face Turn example of the trope. In summary, Viktor makes it no secret that he will eventually be the Judas in the midst of Zs'Skayr's henchmen. In The Vampire Strikes Back, Zs'Skayr resurrects Lord Transyl, a member of a long-extinct species that once enslaved Viktor's people with the intention of ruling the universe together. Viktor voices obvious disapproval for the scheme, even going so far as to call it "madness," and yet at the very end where Zs'Skayr orders Viktor to hold onto Ben so that Transyl can take control over him, Zs'Skayr is still legitimately shocked when Viktor drops Ben at the last second, proclaiming that the Vladats must never rule again.
- Played with in Beast Wars with Dinobot. The character is introduced as a rogue Predacon who defects to the Maximals for the sole purpose of getting payback against his former boss, and actually initially tried to take over the Maximals as their leader. He is portrayed as by far the most aggressive main character, and is actually treated as an Obvious Judas by other main character Rattrap. However, he also happens to be a Noble Demon with a very strong sense of honor, and actually declines multiple opportunities to betray the Maximals over the course of the show. He does end up returning to the Predacons later on, but by this time he had gone through Character Development, which leads him to re-join the Maximals and eventually redeem himself through a Heroic Sacrifice.
- Coverton from Monsters vs. Aliens (2013), being snobbish, scheming and working for Coverlord. Hell, his own name shows that he is a villain!
- The Count Duckula episode "Dear Diary" has Duckula wanting to sell his diary to the Transylvanian newspaper for serialization, but it turns out that the newspaper's readership are a bunch of Philistines who aren't interested in the life of a vampire duck. That evening, Igor comes in with the evening edition with the life of Duckula...through the eyes of Igor!
Duckula: Igor, is this true?!
Igor: Well, I began to think your were right about keeping a diary...
Duckula: Right?! Of course I'm right! I'm always right! But you—you turncoat, you Judas! How—-how could you do this me?
- It does not help a bit that Nanny's diary got syndicated on radio!
