She was recruited by Sasquatch for a strike force to save Alpha Flight. After their rescue from the Plodex, the team agreed to stay together.
An old enemy of Alpha Flight, Flashback, showed up swearing he’d reformed but, claimed he was out of time, and wanted their help in fixing the timeline. With her time-traveling capabilities in the sword, one by one she “killed” Flashback and the members of Alpha Flight to send them back in time, each death messing up the timeline even more.
