From what I've seen, he's most likely a kid (I know, funny coming from a 15 year old). He's fine with people who've done absolutely nothing wrong, but if a person is even slightly affiliated with something negative that Luc knows about, he gets all pissy about the person. He's also generally annoying and somewhat pushes some kind of furry agenda thing. I don't have the chats but he pretty much described how hot he thought Lucario was.
