First Appearance: Hulkbuster
Real Name : Samuel Sterns
Voice: Matt Frewer
|The former lab assistant of Bruce Banner, an accidental chemical spill of
gamma liquids increased Sterns intelligence a thousand-fold, and warped his mind in the process.
Wanting the Hulkís brute strength for himself, The Leader stole one of The Mandarinís rings, and attempted to
travel back in time to the place where the gamma reactor first exploded, and take Bannerís place and claim
The Hulkís strength.
After sending both Iron Man and The Hulk back in time, Leader was caught by Rhodie, and continued to carry
out his plans, as long as he agreed to help Julia. He failed in his attempts to gain the strength, and was
sucked into the portal created by The Mandarinís rings.
