He generally holds back his powers, greatly restraining his full might. On occasion, has unleashed them, showing the true magnitude of his abilities and strength. On some of these occasions, he overloaded the abilities of the Absorbing Man; and fought an enraged Hulk for a prolonged period of time until both fighters reverted to their human forms, whereupon Reynolds was knocked unconscious by Banner. He possesses superhuman speed, making him easily able to evade or catch bullets; and through flight he can travel to the sun and back in a matter of minutes. The Sentry is also apparently invulnerable: Spider-Woman's venom blasts, capable of killing even superhumans at full power, have no effect upon him. Nick Fury has stated that S.H.I.E.L.D. has not yet found a way to kill the Sentry. Iron Man's scanners have found no physical weaknesses in his body.
