Batman has stopped the reign of terror that The Mutants had cast upon his city. Now an old foe wants a reunion and the government wants The Man of Steel to put a stop to Batman.
Batman has not been seen for ten years. A new breed of criminal ravages Gotham City, forcing 55-year-old Bruce Wayne back into the cape and cowl. But, does he still have what it takes to fight crime in a new era?
Phineas and Ferb get trapped in an alternate dimension where the evil Doofenshmirtz rules the tri-state area. They must find a way back home with the help of their pet platypus named Perry, who they discover is a secret agent.
