10 Most Powerful Characters Killed By Iron Man

10. Yellowjacket - Avengers: The Crossing

The Yellowjacket mantle originally belonged to Hank Pym for a while, but as with most superhero identities, it has been held by multiple individuals. A former (albeit, reluctant) criminal and member of the Masters of Evil, Rita eventually switched over to the side of the angels and joined the (futuristic) Guardians of the Galaxy following an alien invasion.

She spent a considerable amount of time with the extraterrestrial group before returning to Earth to warn the Avengers of a future disaster. Upon returning to the present, she found the heroes going toe-to-toe with a brainwashed Iron Man. Kang the Conqueror (under the guise of Immortus) tricked Tony into fighting his friends, and in the process the inventor killed an unsuspecting DeMara.

Fortunately, she was resurrected in the Chaos War but has not been seen since. This version of Yellowjacket was not as powerful as Hank Pym but she still used the Pym Particles to decent effect during her time as a villain and hero.

While DeMara is yet to appear in any Marvel media outside of the comics, at least a version of Yellowjacket (Pym) got the jump on Iron Man in the MCU's multiverse spanning "What If...?" animated series.
