The final fight between the Villains and Heroes. 
  
A villain revealed! Allies aligned! A plan set in motion to deliver ultimate chaos! Wouldn't'cha know it, a group of teenagers are the world's only hope! Not just any teens, but SpyBoy and the heroes of Young Justice. REMbrandt has revealed his true nature, and surprise, surprise; it's a villain the YJ gang has met before! If they're going to defeat him and his diminutive partner in crime, Annie Mae, they're going to need SpyBoy, Bombshell, and SpyGirl to give them an edge. Worlds collide! Mettle is tested! The final battle rages! And, even Butch and Impulse might take a break from their wise cracks to lend a hand. Nah.
