Real Name: Alison Crestmere
While sitting at a café in uptown New York, Alison's powers got the better of her. In an attempt to harness her powers, the Brotherhood attempted to abduct Alison, but failed, thanks to the X-Men. Now, Alison must learn to control her gift and help discover the true motivation of her would-be abductors.
Alison Crestmere discovered that she was a mutant and was being abducted by a military agency. As the soldiers were taking her away, Mystique arrived with Blob and took Allison from the soldiers. She was then rescued from Mystique by the X-Men Wolverine and Cyclops. She was taken back to the Xavier Institute to explore her powers.
Once Alison's training was complete, she was given the codename 'Magma' and accompanied the X-Men to Russia to help Colossus, who was trying to prevent the Brotherhood from obtaining weapons-grade plutonium. After accomplishing this mission, they discovered that Colossus's sister, Illyana, was sick, so she was taken back to the Xavier Institute. Back at the Institute, Professor Xavier, Emma Frost, and Jean Grey entered the Astral Plane to save Illyana. They succeeded, but Xavier was captured by the Shadow King.
After Xavier's capture, The X-Men learned from the Morlocks that General William Kincaid, a leader in the anti-mutant movement, was rebuilding Sentinels. Magneto traveled to his base on Asteroid M and called the mutants of the world to join him on "The Mount".
The X-Men managed to free Xavier from the Shadow King, and Xavier sent them to Asteroid M. There, they discovered that the asteroid was heading for Earth, and they were attacked by Magneto, Mystique, and Sabretooth. After defeating them, they defended the other mutants on the asteroid from attacking Sentinels, until General Kincaid arrived in Master Mold. After defeating General Kincaid, Magma steered the asteroid back into space.
Magma possesses the ability to generate and project intense heat from her body. She can also manipulate solid and molten rock with her mind.
