During the "Last Days" part of the "Secret Wars" storyline, Spectrum devised a plan to destroy Earth-1610 to keep it from colliding with Earth-616. In desperation during the two weeks before the end of the world, Spectrum channeled her full power and went to destroy Earth-1610. However, right before she could successfully destroy the other Earth, she spotted a group of children who lived there, causing her to hesitate for only a moment, long enough for Ultimate Reed Richards to capture her.
