When a strange alien symbiote turns Spider-Man
's suit black, his darkest demons come to light - changing Spider-Man inside as well as out.
This is for when a character who is normally neutral, good, or at least on the overall side of good, temporarily switches sides and/or has a noticeable temporary drop in morality. May be caused by a character being Not Himself
. The character will go back to being his or her old self by either the end of the episode or the next episode.
Compare Face-Heel Turn
& Heel-Face Turn
, when a character either turns evil or good permanently or for a few episodes or seasons.
Contrast with Jumping Off the Slippery Slope
and/or Moral Event Horizon
, which are more permanent. See also Compressed Vice
for problems other than villainy (though they may be cause for it) that last an episode.

Anime and Manga
- In the Black Rose duelist arc of Revolutionary Girl Utena, some of the people Utena has to fight are her brainwashed friends.
- During the late nineties, Iron Man went insane and became a villain, only to be replaced briefly by a younger version of himself from a different time. He also Took a Level in Jerkass and acted like a villain in the Marvel Universe for about a year after Civil War.
- The Civil War thing was solved by a Heroic Sacrifice, that knocked his mind back to a 'him' made before the Civil War.
- While he doesn't quite become a full-blown villain so to speak, Spider-Man shows a semi-evil side in Spider-Man 3 when the symbiote he has on his suit results in a major increase in vengefulness and aggressiveness. He doesn't switch sides; he's fighting against the same enemies as he was immediately before; but his "influenced" side has him doing things he severely regrets and that the series portrays as very clearly wrong.
- Indiana Jones temporarily becomes a Thuggee cult member in Indiana Jones and the Temple of Doom and nearly sacrifices Short Round and Willie in the process, but he manages to snap out of Mola Ram's mind-warping in time.

- The EMH on Star Trek: Voyager was reprogrammed to perform unethical-at-best medicine by the Equinox crew.

- Done again in the Angel episode "Sanctuary" where Buffy is the villain because she wants to kill Faith out of revenge.
- Willow at the end of season 6 when she becomes Dark Willow and eventually tries to destroy the world. She gets better.

- Shawn Michaels was basically always a face after his comeback in 2002, but he turned evil for about a month to beat up Hulk Hogan. Literally the night after the match he was back to being a good guy.
- "Stone Cold" Steve Austin was always an Anti-Hero Villain Protagonist, since he was a face who did heel stuff, but in the InVasion angle he temporarily joined the invading WCW side, which was by definition the "bad" side of the angle. As soon as the angle was over he was back to his old self again.
- Actually, he was a villain even before the inVasion, forming an alliance with Vince McMahon and Triple H. He just went along with the rest of WWE against WCW/ECW as part of an Enemy Mine scenario, and (because he was WWE Champion), everyone in WWE assumed he'd stand with them.

- Spike the dragon is normally good, but his envy in Owl's Well That Ends Well, at the attention Owlowicious is getting, drives him to do some very morally objectionable things, such as planting a fake mouse corpse to try to make it look like Owlowicious killed the mouse. note
- A more threatening temporary villainy occurs during Secret Of My Excess, when his greedy dragon nature gets out of control. When Rarity, not knowing he is the same Spike, talks about how generous Spike was, he feels ashamed of what he has become and immediately reverts back to his old self.
- Twilight Sparkle has this in "Lesson Zero", when Twilight is driven insane in her rush to find a friendship problem, to the point where she deviously creates one herself. Her Apple of Discord plan, however, goes horribly right.
- Trixie goes from a Jerk Ass and arrogant but hardly evil stage performer to a rather sadistic villain who takes over Ponyville in Magic Duel thanks to the influence of the Alicorn Amulet.
