Age of Apocalypse

Ace was a little girl put to work at the Seattle Core, where Illyana Rasputin was being held. She was the one who taught Illyana how to behave to avoid punishment. One day, one of the supervisors was upset with how fast she was working and pushed her off a cliff. Fortunately, that was the same day that Generation X had come to liberate Illyana and Mondo was there to catch her. He promised to return for her when he could and left to search for Illyana. Eventually he came back for her with Gen-Nexters Decibel and Skin, though they were all stopped by interference from Sugar Man, who killed Mondo. It is assumed that Ace was killed in the ensuing riots along with Generation Next.

Ace did not have any mutant powers.
