Gravity Manipulation allows the user to manipulate the local gravity to any extent that they wish. This technique is particularly useful for pinning down or slowing down the user's opponent.
With enough power, an opponent can break free of this technique. However, the opponent has to have a significant amount of power to do so.
They can create, shape and manipulate gravitation, a natural phenomenon by which all physical bodies attract each other, and gravitons, hypothetical elementary particles that mediate the force of gravitation.
