Bobby from Twin Peaks. He starts out as the asshole boyfriend character that's the bad boy of the town, but over time you see he's actually a good kid deep down and was manipulated. You see bits of the real Bobby over the show and how he ends up in Twin Peaks: The Return is even better.

Lust from FMA2003, especially since I saw Brotherhood first where she is just a disposable henchman. Speaking of which, he was always kinda cool but Scar.Yeah, I liked as well what was done with her in the first anime. Her being made out of Scar's brother's lover was a cool concept and her "heel-face turn", if you can call it that, was nicely done.
imo zuko fits this topic even better, he seemed like a pretty generic villain/rival early on but his character development is peakI would definitely agree with you, and I think the vast majority of fans would. One of the best redemption stories in allnof television.
