Janet van Dyne is among the Mighty Avengers who are fighting heroes from the Skrull ship. She is later seen with the rest of the Avengers heading to New York to confront the Skrulls. While fighting the Skrulls, the true purpose of the serum that the Skrull Hank Pym has given her is revealed. After Queen Veranke is thought to be dead, the Skrull imposter presses a button that makes Janet increase in size rapidly, as well as causes her to emit lethal amounts of black-purple energy. Janet realizes that the "new" particles Pym has given her are turning her into a bio-bomb, and she tries to flee the battlefield and take as many Skrulls with her as possible when she explodes. To save both the city and heroes, Thor uses the enchanted hammer Mjolnir to create a spatial warp to seemingly disperse Janet into nothingness. Thor is devastated by the act and vows to avenge her. Upon accepting Janet's death, Hank Pym takes up his ex-wife's role as the Wasp.
