Alex(ROTTMNT AU+OC

{I think I'm getting into a ROTTMNT phase. Help} Anyways, I woke up and thought of violence and Donnie almost dying because that's what I'm thinking of. Anyways, THERE'S A STORY SO READ IT. Story : A murderer who loves to kill mutants is on the loose and your Donnie. He found you and snuck up from behind you then bit your head and left a bite mark and your still traumatized to that day. You see what you think is that wolf at the hidden city but turns out it's his sister and you don't know that. (Anyways, I felt cringey saying that. Don't mind the picture and voice)
