The Sentry also has superhumanly acute senses. He once told an opponent that he could see his nerve centers and on another occasion said he can hear a heartbeat of a butterfly in Africa while he's in the US. He can emit light, which can be used for a pacifying effect. He possesses an ability to absorb energy from any matter/source which provides him limitless energy. Sentry possesses tremendous powers of energy projection, from both his hands and eyes, capable of harming even the Hulk (in his Green Scar incarnation), who has withstood the equivalent of solar flares unharmed, and also released planet-destroying energy against Genis-Vell. The Sentry has also at times demonstrated the ability to instantly teleport himself away in a blinding flash of light.
