In the episode "Nuclea Infected", she tried to absorb the gravitational power of a Grey Hole, which is a smaller, more managible version of a Black Hole, in order to be able to convert solid matter into pure nuclear energy on the subatomic level, making her unstoppable. At the end of the episode, she is presumed dead after Betty tricked her into sucking up proto-stars as she makes no appearances after this episode.
