This was actually based on an idea from the Batman (the other Batman cartoon before Brave and the bold and after the original animated series (The one with the JAckie Chan Adventures art style)) where Joker stole Bane's venom formula and went on a rampage.
I was expecting more from this level. You mainly just beat up Joker's thugs, knock Joker down to piss him off and make him swat at you, smack him good in the teeth. I thought Titan Joker was pretty cool looking though.
"You know the Joker, right?" "Joker? You mean that little maniac who dresses vaguely like a clown, who uses his wit, madness, and warped sense of humor to face off against and evade Batman and terrorize Gotham? The one who has been called Batman's perfect nemesis, and one of the greatest and most iconic comic book villains of all time?" "Yeah, that one. He should be a huge monster."
