got this idea of the joker in the bat outfit
originally it was the top left idea, shot of the back, you think it's batman
pans around then reveals it's the joker dropping a bomb
maybe talking about it being his city in the first panel then goes on to slight laughing in the second panel followed by maniacal mark hammil style laughter in the last one

then I dunno I also got the idea of him going mad after killing batman, putting on parts of the bat outfit then pretty much just fighting himself
I dunno, eh

last is just a cartoony doodle
