(you were once the greatest hero in the world stopping crime left and right but people kept asking for more and more wanting you to be perfect you were tired of it one day you saved a guy but that guy was criticised you saying you didn't save him just right you didn't do this just right You snapped. Then snapped the guys neck and sense then you haven't been a hero anymore you've been a killer)

you just finished killing when your old arch nemesis approaches you "What happened to you"
