*** Aketchi's name is also a tip off, though this is a bit lost to western viewers; He shares his name with UsefulNotes/AkechiMitsuhide, one of the more notorious figures from the UsefulNotes/SengokuPeriod. Mitsuhide was a trusted vassal of UsefulNotes/OdaNobunaga who, for reasons that are still debated today, turned on his master and killed him right as Nobunaga was on the verge of unifying Japan. This is like naming a character after "UsefulNotes/MarcusJuniusBrutus" or "UsefulNotes/BenedictArnold" in western media.

** Dusknoir from ''VideoGame/PokemonMysteryDungeonExplorers'' is initially portrayed as a heroic explorer trying to stop the evil Grovyle from stealing the Time Gears and destroying the Pokemon world, but is a rather sinister-looking Ghost-type Pokemon. It then turns out that ''Grovyle'' was the real hero trying to ''save'' the world by returning the Time Gears to their rightful place, and that Dusknoir was the real villain due to him being [[DiscOneFinalBoss Primal Dialga's]] henchman.
** Nuzleaf of ''VideoGame/PokemonSuperMysteryDungeon'' has received this reaction from quite an number of players. He acts pleasant enough with the heroes, but [[VideoGame/PokemonMysteryDungeon the series]] has a tradition of making [[BitchInSheepsClothing the overtly nice ones]] be EvilAllAlong. He also seems a little too interested in the player character's amnesia and Serenity Villages's high security area. So of course, he eventually betrays you and reveals he is TheMole for [[BigBad Dark Matter]] (albeit a BrainwashedAndCrazy one).

*** Akechi doesn't get as much attention shown to him in promotional material, hinting that he' not a real member of the team.

*** In the PS2 remake, it's made obvious that Hugo is a smarmy JerkAss ready to betray the King of Seinegald, complete with his redesign for the game sporting FourEyesZeroSoul, a BeardOfEvil, and a SlasherSmile, yet it's a shocking twist in-universe when he has Leon steal the Eye of Atamoni.

** One of the factors to how obviously the Traitor character in any given ''Tales'' game will be portrayed comes down to [[SlidingScaleOfIdealismVersusCynicism Idealistic vs. Pragmatic spread among the party members]]; ''VideoGame/TalesOfVesperia'' 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.
** ''VideoGame/TalesOfSymphonia'': 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 [[ChivalrousPervert Zelos]] is the next traitor in the group. He disappears at times, has convenient excuses or explanations for things. His ObfuscatingStupidity didn't fool any player for very long, either. Ultimately, however, it's subverted in that Kratos is really on your side the whole time, and in most story routes Zelos is too.

* ''VideoGame/KirbyAndTheForgottenLand'' is a sort of {{double subversion}}. Since the series previously had twist villains like [[VideoGame/KirbySuperStar Marx]] and [[VideoGame/KirbysReturnToDreamland Magolor]], one might expect Elfilin to end up the same way. But it turns out that he really is benevolent... because he's the good side of a LiteralSplitPersonality, with the evil side being [[BigBad Fecto Forgo]]. When the two merge into Fecto Elfilis, it doesn't hesitate to attack Kirby, and he has to rip Elfilin right back out of it to defeat it.

* ''VideoGame/TheSakabashiraGame'': Evan [[DarkIsEvil wears black]], has [[EyesOutOfSight his eyes ominously covered up by his hair]], is quick to [[InsufferableGenius brag about his intellect]], [[StealingTheCredit takes credit for the group's progress despite Alex having done most, if not all of the heavy lifting]], and [[NoSympathy insults another of his fellow contestants upon discovering his corpse]]. It comes as no surprise when he stabs two of his companions (one of them to death), is revealed to have [[CainAndAbel murdered his sister]], and becomes a demonic monstrosity attempting to kill Alex.

* ''VideoGame/{{Cuphead}}'': From the DLC ''The Delicious Last Course'', Chef Saltbaker initially appears as a genuinely nice fellow who shows no signs of a single vice, in contrast to the other characters' more rounded personalities. Adding to the fact that no one else in the cast was set up as a potential suspect, the moment Saltbaker is revealed to be the DLC's BigBad and subsequently its FinalBoss came to no surprise for plenty of players.

** In ''VideoGame/Persona5'', the InMediasRes part of the story begins with the Thieves getting arrested because a traitor sold them out. For various reasons, you can pick out that it's Goro Akechi, the detective investigating the Phantom Thieves turned EleventhHourRanger due to a combination of {{Blackmail}} and EnemyMine, about as soon as he's introduced.
** Akechi doesn't get as much attention shown to him in promotional material, hinting that he' not a real member of the team.
** He claims he got his Persona totally off-screen, unlike all of the other Phantom Thieves. There's no real reason for the game to pass up a perfectly good dramatic Persona awakening scene... unless said scene would be a spoiler, like if it had shown his black outfit and Loki persona.
** His unlockable outfits tend to belong to other games' villains.
** And of course, the smoking gun: when he first meets the gang in May, he asks if someone mentioned pancakes. Someone ''did'', but it was Morgana (he mentioned that a certain building looked like a stack of pancakes), and only people who have entered the metaverse can understand Morgana's speech as anything but cat noises, while Akechi later claims he only got his persona in November, thus giving away that he's lying...
** In a unique twist on this, after you get back to the starting point it's revealed that he's just as obvious in-universe as out; Joker almost immediately twigged to the 'pancakes' comment and had formulated a plan to outmaneuver Akechi in the casino heist. Even his supposed boss, Shido, was well-aware that Akechi planned to betray him eventually and had a contingency to kill him when he tried. Even in ''VideoGame/PersonaQ2NewCinemaLabyrinth'', several members of the [[VideoGame/Persona4 Investigation Team]] and [[VideoGame/Persona3 S.E.E.S.]] realize that this trope is in play after being around Akechi for long enough.

** In ''VideoGame/Persona5'', the InMediasRes part of the story begins with the Thieves getting arrested because a traitor sold them out. For a variety of reasons, it's fairly obvious that it's Goro Akechi, the detective investigating the Phantom Thieves, who'd recently forced them to let him join them with a mix of {{Blackmail}} and EnemyMine so that he could lure them into a trap. In a unique twist on this, after you get back to the starting point it's revealed that he's just as obvious in-universe as out; Joker had him figured out ever since May (the failed heist is in November), because he unknowingly revealed he'd been to the Metaverse by then in an offhand comment. Even his supposed boss, Shido, was well-aware that Akechi planned to betray him eventually and had a contingency to kill him when he tried. Even in ''VideoGame/PersonaQ2NewCinemaLabyrinth'', several members of the [[VideoGame/Persona4 Investigation Team]] and [[VideoGame/Persona3 S.E.E.S.]] realize that this trope is in play after being around Akechi for long enough.
