During "The Ultimates 3" miniseries, Janet becomes co-leader of the team, along with Captain America, and now sports a crimson-and-gold outfit and a mask. She begins to reconcile with her estranged husband, and later works with the Ultimates and Wolverine to stop the plans of Ultron. She and Hawkeye frequently clash thanks to her teammate's almost suicidal nature. Having gone missing during the flood in Ultimatum Wave, Hank Pym and Hawkeye search for her, only for Hawkeye to discover her body being eaten by the Blob. Hank tells Hawkeye and Iron Man (Tony Stark) to take Wasp's body to activate "the Jocasta project".
