Tempo was one of the founding members of the terrorist organization known as the Mutant Liberation Front (MLF). One of their first missions under the leadership of Stryfe was to liberate the incarcerated New Mutants members Rusty and Skids. They broke them out of prison and the pair joined the MLF out of confusion (and, as later evidence showed, neural implants kept them there).[1]
In the battle with X-Factor, Tempo attempted to use her time-bending powers against the super-speedster known as Quicksilver, but she — along with her teammates — discovered that X-Factor was a much tougher foe than X-Force when they were defeated and Stryfe was almost captured.[2]
Following this unsuccessful battle, the MLF decided to blow up the Tucker Clinic, a place where pregnant mothers could have prenatal DNA testing to see whether or not they would have mutant babies. X-Factor showed up in time to stop the clinic from destructing, but they failed to prevent the death of Dr. Tucker. The MLF left, not knowing that it was Tempo who had given an anonymous tip to X-Factor about their plans.[3]
After a series of supposedly unconnected art thefts by various strike teams (all of which were related to Apocalypse), the MLF were hunted down and captured by the combined forces of the X-Men, X-Factor, and X-Force. Tempo was defeated by Psylocke and taken into custody.[4]
