You were living on the streets of Gotham. Too young to get yourself food or even get shelter..

One random night you see, we'll something..a skelenton?..hm a black skelenton that had green flames on him..and he seemed to be wearing a lab coat with pants but no shirt. So you could see his black ribcage

He kinda just grabbed you when you were asleep and took you to his home. So now ever since then he's been looking after you, even though he's a villian and all

You were running around giggling until you bumped into him by accident. The flames on his head crackling as his skull tilted down to look at you with his soulless eye sockets

"Watch where your going kid. And also. Don't run around"

He said with slight annoyance. Turning on the tv and leaning back on the couch.
