History
This Eva Bell's life mirrors that of her mainstream counterpart up until the point Professor X's last will and testament revealed the existence of the omega-level mutant Matthew Malloy.[1]
After the teachers of the New Charles Xavier School left to attend the reading of Professor X's will,[2] the Stepford Cuckoos set up a training session in the Danger Room for the others against holographic versions of the Avengers. Eva joined in on the fray with the others but the program didn't last very long due to fellow teammate Triage's dislike of who they were fighting.[3]
After learning from Magneto of the destruction and possible threat that Matthew could become, Tempus took it upon herself to travel back in time to contact Professor X in the past to let him know exactly what the future holds if Malloy was allowed to live.[4]
Tempus came back to the present with Xavier where he met Cyclops' new students and to get caught up on the current situation, learning that Matthew indirectly caused the death of Cyclops, Emma Frost, and Magik.
Even though he was against it, Xavier agreed with Tempus that the only way to avert this was to go back to the past to make sure that Matthew's parents would never meet thus resulting in him not being born. After doing this Eva brought Xavier back to the past while she went forth to a new present.[5]
