  • Gravitikinesis: He can negate the force of gravity on himself and on other living beings and objects. He can project a gravity distortion field that can increase or decrease gravity on an object that he is in close proximity to, but not necessarily in physical contact with. He has also learned to increase gravity in a specific direction on an object or person allowing himself and others to simulate controlled, directional flight. He created a planet by pulling the gravity around Terra-Man trapping him in the centre.


  • Legion Flight Ring: Like all Legionaries Star Boy wears a flight ring. It allows him self propelled flight and protection in the vacuum of space.
