The Mighty Orbots (1984)

In the future, Earth is threatened by various enemies, but none worse than the organization called Shadow, lead by the cybernetic menace known as Umbra. Against this, the Galactic Patrol strives to protect Earth, but the mild mannered young scientist, Robert Simmons, does more. In times of peril, he secretly fights as the leader of the Orbots, a team of unique artificially intelligent robots each equipped with their own unique capabilities that are invaluable in this war. Together, whether individually or united as parts of a giant combined robot, they represent Earth's most powerful defense.
