Sleepwalker possesses superhuman strength, exceptional durability and resistance to injury, and flotation-like flight. He is also capable of the projection of crude images of what he's seen from his eyes. His only offensive power was his "warp gaze". With this vision-based power, Sleepwalker could alter the shape of physical objects and twist them to his purposes. He could also modify the physical characteristics of the objects he affected-making them harder or softer, for example. Sleepwalker initially demonstrated this power by using it to distort a sidewalk to capture a criminal. He also used this ability once on air molecules to create a wind tunnel for faster aerial travel. Owing to an oath sworn by all members of his race due to the great physical and mental pain it could cause, Sleepwalker tried not to use his warp beams on living entities.
