An all-new set of adventures, featuring full-colour art! The worst super-villains in Batman's Rogue Gallery have broken out of Arkham Asylum, and he's got his hands full trying to round them up. They're usually easy enough to defeat alone, but this time they've got a surprise in store for Batman: they've decided to team up! From Mr. Freeze and Captain Cold, to the Joker and Harley Quinn-these are the worst Super-Villain combos Gotham has ever seen. It'll take a lot of help from his Justice League friends-and some Bat-family friends, too-for the Dark Knight to put these bad guys away for good!
