Egghead is a Marvel Super Heroes minifigure that appears in LEGO Marvel's Avengers and LEGO Marvel Super Heroes 2. This article is about the Marvel super-villain and not the DC Comics super-villain of the same name.
Dr. Elihas Starr was an atomic-scientist with a bald malformed head which resembled an egg. After Elihas sold top-secret plans to sell on the black-market, he was disgraced and discredited, forcing him to become employed by crime-lords. To prove his talent, the scientist was forced to use his tech to fight Ant-Man only to fail and be forced into hiding.
Following his defeat, Egghead was forced into poverty but he would resurface time and time again to fight Ant-Man who became his arch-nemesis. Often Egghead's plots involved the use of technology which controlled insects in-order to fight those of Ant-Man's.
Marvel Cinematic Universe
In the MCU, Dr. Elihas Starr was a scientist that worked for SHIELD alongside Hank Pam only for Pym to discredit his work. Elihas continued his work however but it resulted in an explosion that killed him and left his daughter Ava with superpowers.
