Egghead

Egghead is a Marvel Comics character that appeared in Avengers Assemble, voiced by Yuri Lowenthal. He is a briliant scientist who was fired from his job as a prop maker for a movie studio, and thus decided to become a supervillain, using his scientific mind and high-tech gadgets and weaponry to sabotage a movie based on the exploits of the Avengers. Thankfully, the actual Avengers, with the help of Ant-Man, managed to stop him. Most of his gadgets and weapons have an egg theme, hence his supervillain codename.

Egghead was created by Stan Lee, Jack Kirby and Larry Lieber.
