Dark Demon

The Dark Demon is an alter-dimensional ego from the 3rd dimension who wishes to advise children to stay inside during the school year as to not disappoint them.

He presumably does not have good ties with the demons living in his backyard, as when he throws his homework into a black hole on his porch, there is a hissing noise and he says "I hope I didn't provoke them"

He wears black sunglasses, a raccoon fur hat, and a black bandana.
