Zarina can manipulate cells within her own body and within the bodies of others. She doesn't need physical contact to use her ability, but needs to be close to the person. She can use it to cause injuries to heal rapidly, forcing cells to divide and repair the damage even if they were cells which wouldn't do so naturally, like neural cells. She can also mutate and damage cells. Additionally, she can use her ability to alter appearance in small ways, but currently finds that her effects wear off after a few hours.
