Merge:Petra

Petra Kristensen is a mutant in the Marvel Comics Universe. She first appeared in X-Men: Deadly Genesis #1. She was created by writer Ed Brubaker and artist Pete Woods in the limited series X-Men: Deadly Genesis. Was one of the "Missing X-Men".

History
Petra was the first of her family to be born in the United States. Her mother, father, and brother all immigrated from Denmark while her mother was pregnant with Petra. They lived the typical American life in the suburbs of New York City for most of Petra's childhood.

Shortly after her thirteenth birthday, Petra's family was killed by a rockslide while on a camping trip. Unknowingly, Petra used her mutant powers of earth manipulation to avoid getting hurt.

After spending weeks in Child Protective Services, Petra was sent to live in New Jersey in a foster home. She was placed in a home that had five other children that were forced to share the same bedroom. Her foster mother was old and uncaring and her foster father was too caring, trying to hold and touch Petra all the time.

One day on an outing to Central Park, Petra's foster father tried to touch her but sank knee deep into the ground. It was then that Petra realized that she was a mutant, and she ran away. She found a cave and hide there for days crying, knowing that with her abilities she could have either killed or saved her family.

She camped in Central Park for a couple years, using her power to manipulate rock caves into shelters to avoid being arrested and sent to juvenile detention centers. When she was sixteen, she discovered another useful aspect of her ability. By concentrating hard enough, she could turn coal into diamonds. For a year she used this aspect of her power to make diamonds of varying size to sell to pawn shops so she could buy food and survive.

One day though, a pawn shop employee said he was going to call the owner of the store, but he really called the police. Running to her rock shelter, the police found Petra before she could hide, and took her into custody after a brief battle. When she awoke, a female guard informed her that she was being released into the custody of a woman who was there to help Petra, who was later revealed to be Dr. Moira MacTaggert. This at first frightened Petra because she had never known anyone to try and help her because of her abilities, only hurt her.

After some time with Dr. MacTaggert, her friend Professor Charles Xavier took Petra and the other kids within the doctor's custody, Sway, Darwin, and Vulcan, and sent them to rescue the original team of X-Men trapped on the mutant island Krakoa. After she instinctively used her mental powers to bury Vulcan and Darwin, she became incinerated by the volcano creature.

Powers
Petra is a terrakinetic or geokinetic, having the ability to control the classic element of earth; sand, stone, rock, lava, and/or dirt and can even transform the consistency of earth and rock, such as turning a coal into a diamond. She also can use this power to cause minor earthquakes and create shapes out of solid rock.
