History VillainDecay / LiveActionTV

** Meg in seasons 1 and 2: Remorseless demon who commits multiple murders for little reason, says she has done much worse for much less, tortures, threatens, and taunts the Winchesters, kills many of their friends, [[DemonicPossession possesses]], [[FrameUp frames]], [[AttemptedRape and nearly rapes]] Sam, kidnaps Jo and [[BreakThemByTalking traumatizes]] [[NearRapeExperience her]], and nearly tricks Dean into killing Sam. Meg in seasons 6-8: [[DeadpanSnarker Snarky]] IneffectualSympatheticVillain and sort-of LoveInterest for Castiel who dies a sort-of hero via a combination of RedemptionEqualsDeath and YouShallNotPass to Crowley.

* ''Series/BigWolfOnCampus'': Tim and Travis are just ordinary bullies who want to eliminate the "Pleasantville Werewolf"/Tommy Dawkins, but are threatening in the right circumstances whenever they take advantage of the heroic werewolf's [[HeroWithBadPublicity fragile reputation]]. However, the show's MonsterMash gallery of villains quickly eclipsed them in relevance, occasionally acting as flunkies for them or otherwise being a nuisance, and in their final appearance, only one of them shows up and isn't acting as a threat.

** Q turned from a frivolous yet dangerous omniscient being who nevertheless delivered some important [[AnAesop Aesops]] to Captain Picard, to a lovesick puppy who goes to Captain Janeway for advice on parental relationships and conflict resolution in the Q Continuum. Q really was one of those characters who were a case of DependingOnTheWriter, especially in TNG. He's creepy and borderline sadistic in "Encounter at Farpoint", then campy and unwittingly annoying in "[=QPid=]", then he's back to being sinister in "True Q". It's debatable whether or not he was even actually a villain, considering how many times he (sometimes indirectly) helped Picard and the crew.

** Joffrey starts off by becoming King and killing Ned and setting the War of Five Kings in motion, and for most of the first two seasons he leads a tyrannical reign of terror that starts to cause problems for even the people on his own side. By the time Season 3 hits however, he rapidly starts losing his credibility as a villain and is reduced to nothing more than a little braggart whose own mother barely takes him seriously anymore, because Lord Tywin, who wears no crown, has taken control of King's Landing and becomes the king in all but name. Doubly highlighted by the introduction of far more serious and threatening antagonists such as Roose Bolton and Ramsay Snow in Season 3.
** In Season 4, Ramsay Bolton is shown to be a BloodKnight MasterSwordsman who is able to defeat the "most vicious killers on the Iron Islands" while shirtless, with contemptuous ease. Come Season 6, he's a DirtyCoward who goes down after a few punches to the face.
** Littlefinger is initially established as one of the show's most prominent BigBad contenders, setting the whole plot into motion and expertly weaving his way in and out of Westeros' political web. Come Season 7, he's been reduced from a MagnificentBastard to a small-time schemer and TokenEvilTeammate for House Stark whose screen-time mostly consists of standing around in dark corners and staring creepily at people. [[spoiler:In the end, he dies pathetically, begging for his life.]]

** Partly due to SeinfeldIsUnfunny, Jerri Manthey. She was seen as the original survivor villain mostly because she was the first to be called that. (Richard Hatch is probably more of the "original" survivor villain) She was actually booed off the stage in ''All Stars'', yet years later after the likes of Boston Rob controlling the game, Russell Hantz sociopathically pushing his way to the finals and ''admittedly'' griefing his fellow players, Jonny Fairplay lying to get a sympathetic advantage, Ami Cusack, and players like Naonka, Corrine, and Randy just being a JerkAss...When Jerri showed up on stage in ''Heroes vs. Villains'' and wasn't like ''any'' of those, people actually ''applauded'' for her.
