Professor Pyg and Mr. Toad are back...and they've set their sights on Gotham's elite couture culture. Leaving clues that only Batman can decipher, they attack both a model and a clothing designer -- encasing them in deadly traps. Although Batman and Katana are able to save the day, they miss Pyg and Toad's master plan: to destroy the yacht where the after-party for Gotham's Fashion Week is being staged. Every fashion icon in the world will be there... as well as Bruce Wayne!

Batman and Katana encounter a strange Man-Bat creature, who is the experimental result of Pyg and Toad's animal army of mutant humans.
