The Avengers, old and new, must find a way to free the Inhumans and the world from Ultron's control. When Ultron takes control of Iron Man, Doctor Strange comes up with a plan that might result in Iron Man's sacrifice.
"Marvel's Avengers Assemble" reunites the most popular super hero team - Iron Man, Hulk, Captain America, Thor, Hawkeye and Black Widow, along with newcomer Falcon, marking the first time in animation history this distinct team of heroes will join forces.
Led by Iron Man, the heroes train and live together in their new headquarters in Avengers Tower. The planet's most dangerous villains don't stand a chance when the Avengers assemble - whether they are stopping Dr. Doom from conquering Asgard, Attuma driving the Atlantean Army into New York City or Dracula unleashing vampire hordes, the Avengers must work together to succeed.
