The user can manipulate mitosis, the division and replication of cells in themselves or others, allowing them to speed up, slow down, concentrate, make efficient, halt, and reverse mitosis. This allows them to rapidly regenerate as well as harm others by undoing their mitosis or stop people who shapeshift by mitosis. User can make mitosis more efficient to heal wounds in seconds or slow the aging process down. By reversing mitosis on cancerous cells, they can effectively prevent its spread, and even remove it.
