Getting sucked into a wormhole created by someone with this ability is almost certain to be fatal.
Gyrokinesis (sometimes called Gravity Manipulation or Gravikinesis) is the ability to mentally manipulate the physical force that is responsible for interactions between objects with mass. Basically this permits one to increase or decrease the effects of gravity around any desired area making objects extremely lighter or heavier. Someone could crush things by compressing them with intense gravity or, with greatly advanced concentration and ability, create a small vortex. One this ability can shift his center of gravity and defy it, by jumping up to extreme heights and for greater distances than normally possible (as if on the moon), and even pushing or pulling objects around him by manipulating the gravitational force.
This ability manifests as a miniature gravity field around the possessor. Adrenaline rushes increase the gravitational fields, and allows conscious manipulation of this gravity field. Gyrokinesis is also the gateway for Cross-Dimensional Awareness and Instantaneous Transmission.
