Petra Kristensen

Petra Kristensen, also known as Petra, was a Class 4 mutant from the United States and a member of the X-Men.

Biography
Petra was the first of her family to be born in the United states. Her parents and older brother immigrated from Denmark while her mother was pregnant. Soon after her thirteenth birthday, a mysterious rock slide occurred while the family was on a hike, killing all except for Petra, who survived without a scratch. Just before the accident, she had experienced a strange feeling while staring at the jagged rock that ended up killing her brother.

She was then placed in a crowded foster home in New Jersey. She was afraid of her foster father, who seemed to stare at her. One day, while they were vacationing in Central Park, he attempted to molest her, only to find that the ground was swallowing him up. Petra was terrified as the man called her a "freak", so she ran away. She began manipulating nearby caves to provide her with a safe and secure hiding place. To survive, she panhandled and occasionally stole, but stayed away from drugs and prostitution. She avoided others whenever possible, unsure of what they would do if they found out that she was a mutant.

Around the age of 16, Petra learned that she could turn coals into diamond and began pawning them to make money. Although she kept the diamonds small so as not to draw suspicion, the pawnbroker she went to eventually called the police and arrested her. She awoke in a holding cell with Moira MacTaggert, who explained to her that she had managed to get the charges against her dropped and convinced the authorities to release Petra into her care.

After some time with Moira, Petra was taken to Professor Charles Xavier, who took Petra and several other children within Moira's custody, including Sway, Darwin, and Vulcan. Xavier sent them to rescue the original team of X-Men who were trapped on the mutant island Krakoa. After Petra instinctively used her powers to bury Vulcan and Darwin, she and Sway were incinerated by the volcano creature, but Petra's actions helped save her two friends.
