Elihas Starr, better known as Egghead, is a Marvel Comics supervillain characterized by his unusually large, bald head and genius-level intellect. He began his career as a government scientist, but was fired for unethical experiments.

Driven by resentment, Starr turned to a life of crime, using his vast scientific knowledge to develop advanced weapons and schemes. He became a recurring antagonist of Ant-Man and the Avengers, often employing mind control and technological innovations to achieve his goals.

Egghead has led various criminal organizations and orchestrated intricate plots, consistently seeking power and recognition. His arrogance and disdain for others, combined with his brilliant mind, made him a formidable adversary.
