|Real Name||Samuel Sterns|
|Powers and Abilities||Greatly Enhanced Intellect|
Sterns was part of the clean-up crew that arrived after the Gamma Reactor test that created the Hulk. An accident on the scaffolding caused him to fall into a pool of gamma radiation waste. His intelligence was greatly enhanced and he devoted himself to taking the power of the Hulk for himself.
When Bruce Banner was separated from Hulk, he took the body and transferred his mind into it. However, Hulk's brutish mind was too much for him and he lost control.
Leader is arrogant and condescending due to his intelligence. He believes himself to be superior to everyone else and has no concern for the desires of others. His obsession with obtaining Hulk's power borders on foolishness.
Leader was voiced by Matt Frewer in all appearances.
In the Comics
He once freed Rhino to fight Hulk.
