Vance Astro is a mutant who possesses the psionic ability of psychokinesis, the ability to affect matter with his mind. Vance's psionic powers can only be manifested as "psyche-blasts", focused psychokinetic blasts of explosive concussive force, which can disrupt the synapses in the minds of any living being they strike. He can focus the energy at will, creating anything from a narrow beam to a 360 degree expanding sphere of force. Over time, Vance has shown some marginal improvement of the control of his psychokinesis, such as generating small psionic pulses to slow the descent of falling people, or gentle psychic bursts to move objects forwards or backwards (all without inflicting any damage on the people or objects). Vance can only employ his psionic powers at maximum exertion for about a half-hour before suffering mental fatigue, after which he must replenish his store of psionic energy. During the time when he carried Captain America's shield in combat, he would use his power to propel the shield and manipulate its flight path, simulating the Captain's use of the shield as a throwing weapon. Going by the code name Hollywood, a 1,000-year-old Simon Williams's helped to augment all of Astro's abilities by a transfusion of Williams's ionically-enhanced blood.
