Mackenzie’s older brother who served as a bully to Joseph before he was frozen within Intermine Laboratories. In the present day, he cannot talk, but he makes a significant presence in a flashback to Joseph’s youth. Cocky, arrogant, and condescending, Leon is one of those characters who makes a very short, but emotionally moving character arc. Leon is a minor character, appearing in only one episode. Snobby, Slightly thuggish bully. Provocative, seemingly mad at everything and everyone, and HOW DARE YOU KICK ME, I’M BETTER THAN YOU.
