Hehe! I'd agree with you if it was this Joker, but he's a rather less well known Joker, whom I happen to be rather fond of. There aren't that many strong, snarky, disabled characters in my video games, y'know? And when I say 'many' I mean 'at all'. Video game fandom for great (social) justice!

...because seriously, as a media it needs all the help it can get.
