Robin is a pretty neglected dimidian character. He’s a fluffy little asshole who makes himself seem non threatening at first but he’s actually quite cruel and has a nasty temper. Here he is making poor Gus feel bad about himself :c I’m not sure how nasty Robin is. I don’t want to make him completely evil or anything. He’s not the kind of guy you'd easily get along with at least. He’s really short. Gus is considered to be a smaller example of a dimidian but he’s clearly taller than Robin!
Robin started out as just being a mischievous little thief but he just kind of developed into this. He probably still steels things though!
