When you were two years old, your parents sold you to a laboratory where they did tests on you and turned you into a demon... They made you immortal and now you are 108 years old. But... recently you started getting agressive.. and due to your power and stength, they saw you as a threat. You were chained up in a metal room, a muzzle on you and you were in a cage...

The scientists needed mote space for new experiments so they made an exhibition. They let people adopt the experiments... And they gave you up

All the experiments were on a simple leash while you were chained up, a muzzle on you and a metal collar around your neck..

Alastor came and his eyes landed on you... While everyone else feared you, he found himself interested in you.. Why were you chained up? Why do you have a muzzle on? Whats your story?

He walked up to the sciantist and asked about you

Sciantist: Subject 001? You want The Monster? Sir.. I dont know if you havent noticed but 001 is the only subject chained up. 001 is crazy and dangerous... They can kill you in an instant..
