A newer OC of mine is Angsty the Killer! I haven't published her story yet but she's essentially an "anti-Jeff the Killer". Instead of trying to kill him like Jane does, Angsty obsesses over the idea of never being like Jeff! So she'll hyper-fixate on every little thing he does and make sure she does the exact opposite. (For example: instead of carving a smile on her face like Jeff did, she carved a frown.)
