Ultimate Avengers

The Ultimate Avengers is an animated movie, featuring The Avengers.

Plot
In the last days of World War II in Europe, Captain America, due to enhancement by a "Super-Soldier Serum", prevents the Nazis from launching an intercontinental missile. They are also soon revealed to be shape-shifting extraterrestrials led by one acting as SS officer Herr Kleiser.

The exploding missile knocks the Captain out and he falls into the icy waters of the North Atlantic, presumed dead. 60 years later, Captain America is found and revived by a S.H.I.E.L.D. team led by General Nick Fury.

Bruce Banner and Betty Ross lead a team of scientists working to recreate the Super-Soldier Serum in order to try and stop the real power that backed the Nazis - the alien Chitauri. Banner thinks the Super-Soldier Serum is the key to him controlling the Hulk, and he secretly uses his blood to try to create a cure, instead of using candidates that had been selected for the rebirth procedure.

The Chitauri destroy a S.H.I.E.L.D. satellite designed to track the alien ships. So Fury is forced by superiors to order the implementation of "Project Avenger", to gather together a team of Superhumans.

Fury tries to recruit - with mixed success - Giant Man (a scientist recently redacted from S.H.I.E.L.D), Wasp (Giant Man's wife), Iron Man/Tony Stark (an industrialist playboy), Thor (the Norse God of Thunder) and Black Widow, a S.H.I.E.L.D. assassin. After several setbacks, including a botched mission that led to almost the entire team quitting, the heroes unite to fight the Chitauri.

Although successful, the team must then fight an out of control Hulk. Banner wanted to try his new serum against the attacking aliens, releasing his alter ego for the battle. The team managed to eventually distract the Hulk long enough for Betty to calm him, and Banner is then incarcerated.
