Miss not-so sidekick, Doctor Elise and The Justice of Villanous Woman... Uhh well there're webtoons with mc's who used to be side characters like The Reason Why Raeliana Ended Up in the Duke's Mansion, The Abandoned Empress, Suddenly Became a Princess One Day and I can't really remember, hehehe
Death Note, Paperweight Dye (sort of), Code Geass (many see him that way), Kare no Satsujin Keikaku, Kobe no Katachi (not a villain, but a horrible human being), Higurashi no Nako Koro ni series (sort of; constantly changing)
*Paperweight Eye
