Introducing the prototype of his newest product to the entire world – the Ion Cortex, a powerful device capable of solving the world’s energy crisis – Bruce Wayne hires brilliant scientist Dr. Jason Burr to work on the project. The announcement also draws the attention of one of the most dangerous groups in the world – the League of Assassins. When one of the League’s deadly assassins, Silver Monkey, attacks Wayne Manor to kidnap Dr. Burr while Batman’s in Gotham, it’s up to Alfred and Katana to keep the assassin at bay until Batman’s return.

Katana saves Batman from Cypher , a part robot villain with the powers of mind control who is seeking the Ion Cortex.

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!

Jason Burr steals the Ion Cortex in order to make a deal with the League of Assassins.
