Is there a name for this trope?

In sci-fi and/or fantasy story lines a new character is introduced who is a bad guy and who has very formidable powers.

Somewhere along the line he/she turns good and fights along the good guys. Now all of a sudden his/her powers seems weaker and/or there are limitations on his/her powers that didn’t seem to exist when (s)he was evil.

Is there a name for this?

Sounds like a combination of Heel Face Turn and Villian Decay.

Reminds me of Magus in Chrono Trigger for the SNES.

TVTropes has is as “Redemption Demotion” http://tvtropes.org/pmwiki/pmwiki.php/Main/RedemptionDemotion

Wow, the very second I went to TV tropes to search, you posted this and it seems to describe the exact thing I was thinking of. Thank you.

No problem - I read about the concept on TVtropes a while back so even though I didn’t remember the exact term, I remembered some keywords to search on.

Nooooooo.

How could they not have Sylar from “Heroes” as an example of that trope???

Is there a name for this trope?

Any period movie (or story with time travel, I guess) – gender roles in history – where men didn’t treat women the way we hope they would today: You have to show the male lead treating his woman in a historically unrealistic or inaccurate way (or at the very least, he is uncommonly tender/ gentle/ sensitive), because if you portrayed the male lead (or other male characters we’re supposed to like) realistically, we the audience wouldn’t like them very much, if at all. (My apologies for the way this is clumsily framed.)

Okay, how about this trope (maybe it’s not a trope)?

Any historical movie where you know how the story turns out, and you can’t get into the story because you know Tom Cruise isn’t going to succeed in killing Hitler / Johnny Depp is going to survive this gunfight (etc.), so you sit there through what should otherwise be a thrilling story, waiting for the plot to Get On With It Already.

May be related to any story that takes place during the Jazz Age 1920s, where you wish you could tell the characters to stop drinking and partying so much and to get a job in a solid profession and to start saving every penny and I mean NOW.

Sounds like the extremely obviously named Politically Correct History to me. (note issues with that trope as discussed on the linked page)

Ooo, good job, thanks! I had been looking under the gender/sexuality tropes and wasn’t finding anything relevant (except A Man Is Not a Virgin, which is another of my movie trope pet peeves – yes, reassure me that Sam Gamgee has a girlfriend back home so I won’t think he’s gay :rolleyes: ).

Seeing how he and Frodo would loving gaze into each others eyes, he was obviously bi. :smiley:
