The Elihas Starr incarnation has made several animated appearances and was portrayed in live-action by Michael Cerveris in the Marvel Cinematic Universe film Ant-Man and the Wasp.

The original version (Elihas Starr) first appeared in Tales to Astonish #38 (Dec. 1962), and was created by Stan Lee, Jack Kirby and Larry Lieber.

[1] The second version first appeared in Dark Reign: Young Avengers #1 (July 2009), and was created by Paul Cornell and Mark Brooks.

A gifted government research atomic scientist with an egg-shaped head, Starr was dismissed for espionage and resolved to use his intellect as a criminal mastermind.

[5] Egghead divided his remaining years between attempted world conquest and seeking revenge on his nemesis, often hiding out in the Bowery section of Manhattan in between.

[6] Egghead teamed up with the Mad Thinker and the Puppet Master in a plot to use a laser satellite to blackmail the United States government.

[9] Egghead later kidnapped his niece, Patricia "Trish" Starr, to test a device which allowed him to steal other people's intelligence, and wound up battling Pym as Ant-Man again.

Egghead approached Pym (who was operating as Yellowjacket at the time) with a prosthetic arm that he wished to give to Trish to make amends for his previous deeds.

[22] Although his original programming was "to respect all human life", the female neo-Nazi Big Zero (who seems to have a relationship with him) reprogrammed him to hate minorities.

[30] The Elihas Starr incarnation of Egghead appears in The Amazing Spider-Man, by Stan Lee, Larry Lieber, and Alex Saviuk.
