The Avengers reunite to face an unexpected return of Ultron and encounter new threats like Baron Zemo, the Masters of Evil, the Inhumans, and the futuristic Kang the Conqueror. It's only with the help of heroes like Black Panther, Captain Marvel, Ant-Man, Doctor Strange and Ms. Marvel that they have a chance of surviving an all-out Marvel super hero Civil War, and prove once again, they're a family and their combined strength is the key to remaining Earth's Mightiest Heroes. In the premiere episode, "Adapting to Change", the Avengers learn what it's like to work as a team again and battle A.I.M'.s latest weapon, a new and improved Super Adaptoid developed by the Scientist Supreme.
"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.
