Gravitron

Weight of the Heretic: Gravitron, is a knuckleduster type Century Arm which can manipulate gravity. It is currently used by Izzy Pilkington.

Abilities
Gravitron has the ability to rapidly increase and decrease gravity of whatever it strikes, be it object or environment. It can increase gravity to the point where objects are crushed under their own weigh, or decrease it causing them to instead float. This effect can be applied to a wider area by striking the ground, however the intensity of the change will be weaker.

Skilled users can manipulate their personal gravitational field, decreasing their own gravity to increase agility, and increasing it to strengthen attacks.
