The Avengers: United They Stand (1999)

Avengers (or called Avengers: United They Stand) was an animated series based on the popular Marvel comic book. The Avengers aired on FOX (Fox Kids), in 1999 on the Saturday Morning Cartoon Block.

The Avengers are the world's foremost super heroes, protecting the world from incredible globe-threatening villains. Whether they're robotic like Ultron, extra-terrestrials like The Zodiac, or just super-powered like any other villian, the Avengers are more than a match for any foe.

Avengers only lasted one season with thirteen episodes. A second season was planned, but never occurred. The show did not have many viewers to it. Some say it was because the three characters, Captain America, Iron Man, and Thor were not made as main characters.
