Marvel: Time Travel

Blaquesmith
Blaquesmith possesses the psionic power to displace himself and others at almost any specific point in the timestream and then re-emerge in the physical world, from as much as a few minutes to years by generating chronal energies.

Dafydd ap Andras (Damian Tryp)
Tryp possesses the psionic power to displace himself and others backwards and forwards at any specific point in the timestream by generating chronal energies. He has been seen to travel back as far as the 1st Century, and more than 80 years into various futures

Eva Bell (Tempus)
Tempus is able to displace time with in her "time bubbles" for about a minute and even travel in time for much longer periods. She is also able to change the past without creating alternate realities. One major difficulty with Eva's power is that if she is stressed or panics, she can lose control of it and generate time spheres or time travel unintentionally; this is what caused her to become "unstuck" on two separate occasions. After her years of training in 2099 with Illyana, this tendency is much less pronounced, and the only thing that triggered it was an immediate danger to her loved ones.

Nathan Summers (Cable)
Cable has been hinted to have the psionic power to displace himself and others at almost any specific point in the time-stream and then re-emerging in the physical world from as much as a few minutes to years by generating chronal energies. He could apparently travel in astral form, as well. Cable used the ability once with assistance and may no longer be capable of doing so.

Rachel Summers
Rachel possesses the psionic power to displace herself and others at almost any specific point in the timestream and then re-emerging in the physical world from as much as a few minutes to years by generating chronal energies. She could apparently travel in astral form as well. She could also travel to points in the future.
