Much like his inspiration, he's a mentally stunted man with Acromegaly. Also, his name is still Jedidiah, like how Slasher's name is still Jason.

For the original content though, his father was a Guest that fought in the war and died, leaving him with his older brother (his parents got divorced when he was like 3). His brother was basically Drayton in the original movie, an abusive guy who made his little brother do all the killing.
