This is Robert "Bob" Reynolds, also know as the Sentry. Many years ago, Bob found and drank the same super-serum Captain America used to get his power x1000 because he was trying to get high. He ended up with Many different powers such as:

-Super strength
-Extreme durability
-Super speed
-Molecular manipulation which he can't really control at all
-Flight
-Telepathic abilities
-Resurrection (Which he also can't control)
-Photokinesis

Unfortunately for Bob, he is mentally ill and has a dual-personality disorder. Because of this and his limited reality-warping, Bob created an evil version of himself called the Void. For every good deed the Sentry does, the Void screws something up, making it hard for Bob to do any superhero-ing at all.

This is also a new shading technique for my skins.
