Eva was convinced by her friend to go out clubbing and finally talk to the boy she has a crush on. However, her overprotective brother arrived and ended up causing a fight with the boy and his group of friends. In this moment of stress, Eva's mutation awakened and she froze the entire block in time. What seemed like only moments to her was actually a day gone by. The X-Men Cyclops, Emma Frost, and Magneto arrived to help her.
They explained how her mutant power had emerged, and that they would aid her in her new life. As the time sphere dispersed and the police moved in to apprehend Eva, the X-Men combated them to defend her. Eva quickly became friends with other new mutant, Christopher Muse, as the two talked to each other introducing themselves and discussed their powers.
Eva was created by writer Brian Michael Bendis and artist Stuart Immonen, making her debut in All-New X-Men #1. Eva's brown hair was changed to black after her mutation emerged (an artistic change later reflected on the cover of All-New X-Men #2), likely as a means of helping fans to avoid confusing her with Rachel Grey.

Tempus fights with the team against the mindless ones and they manage to hold off long enough for Magik to get free of Dormammu's control and teleport them out of Limbo.

Tempus helps battle the sentinel before it ends up being called away.
Temporal Bubble- Eva's primary mutant ability is to control time and space. She does this by creating a temporal bubble that freezes whatever is inside. Her powers have shown they can reach the span of a city block and last up to twenty hours. She has shown the ability to create multiple bubbles at once, trapping separate foes in them. When using her powers at first, she was shown getting dizzy due to her lack of control. But as her training continues the side effect of her abilities has seemed to subside.
Time Displacement- While being trained in fighting by Magik, she learned that she has the ability to send the people she traps through time.
