Marceline - Adventure Time
As far as bullies go Marceline is about as awesome as it gets. She’s got style, can play a wicked guitar solo, she’s freaking undead, and as far as hipster vampires go, she’s kind of cute! Maybe all those awesome qualities are why she didn’t stay a bully for too-too long and eventually became one of Finn and Jake’s closest friends. Those mind games she played in the first several episodes were NOT COOL though, man!
