Weird evil guy

cartoongod.fandom.com
The weird evil guy is a guy from cartoongod's (my) youtube channel featuring videos like Steven Universe gets Grounded and Steven Universe Future in a Nutshell episodes. 
He rubs his hands and says "hahahahahahaha" almost every time he says something.
He appears in videos like "Triggered Steven Returns" and "Steven Universe Future Misadventures". 
This image I found is from Steven uses the girl's restroom/grounded.
History
The weird evil guy was featured in my episode called Weird Evil Guy. Most of his history is revealed in this episode. He was a young boy who got into a car crash and was diagnosed with amnesia. The doctor told him that it’ll be fine as long as he doesn’t hit his head again. Because of his amnesia, he was now rubbing his hands and saying “Hahahahahahahahahaha” whenever he was talking.
