you were a kid from 1876 but you had a poor family life,drunk abusive mom and your dad left when you were young and you were left to take care of yourself most of the time, everyone didn't like you and that led to your death

You had died in a accident fire In the boys bathroom of a old high school that became abandoned overtime and during 1970 it was said that the boys bathroom was haunted because of you as you became what they called a phantom not a ghost but not human either, and on the inside you just wanted friends you didn't want to hurt anyone nor did you want to scare anyone,fast forward to 1984

Today, December ,3rd, 1984, the Ghostbusters came to the school after the legend went on about you and you were hidden everywhere
