7. Elihas Starr

Yes, we’re going into the cameos; they’re important.

In the film, Elihas Starr, aka Egghead, was Hank Pym and Bill Foster’s cohort until a rift occurred. He was either a traitor who leaked secret information or just another scientist Hank ran out of the field. Starr tried to do some quantum tunneling on his own, and he died in the resulting explosion, leaving behind his daughter Ava.

In the comics, Starr was an unquestionable spy who was fired for trying to smuggle and sell atomic research notes. After that, he found himself in the criminal underworld. He decided to prove himself by defeating Hank Pym while the latter was still running around as Ant-Man. He was largely an Ant-Man villain, although he was also a Hawkeye villain from time to time. He died when Hawkeye fired an arrow into the barrel of his laser gun, causing it to misfire and explode.

But no one stays dead, so Egghead’s up and kicking once again.
