Batman is determined to show The Joker who's the boss of Gotham City. And The Joker is just as determined to have the last laugh! Batman has Robin, Nightwing and law and order on his side. The Joker has Harley Quinn, Mr. Freeze, Poison Ivy, and a whole host of sneaky villains to back him up. Both sides have cool vehicles and equipment: Batman has his Batmobile, The Joker has his grinning Jokermobile; Batman has Batarangs, Batsub and Batwing; The Joker has his mallet, ice cream cart, and laughing gas. Who'll come out on top?
