What's your hottest character idea that you didn't get to play (long enough)?
Mine was a Wild Magic Sorcerer that vehemently believed he was a regular city guardsman and explained every bit of magic he produced away as pure happenstance.
Mine was a minotaur gladiator turned monster hunter (ua fighter subclass). His name was Daniel Notmonster and he'd been called monster so much during his days in the arena that he internalized a hatred of monstrosities. He was driven to prove he wasn't a monster by killing any he came across. He would also collect a bone from each monstrosity killed to scrimshaw a scene of the battle to kill it.
