In the comics, Billy Butcher doesn't possess powers. He relies on his combat skills, experience, and a never-back-down attitude to fight against those with supernatural abilities.
In the comics, Butcher definitely had powers. His powers included superhuman physical attributes and sometimes special abilities granted by certain circumstances or substances. These powers made him a formidable force.
She-Hulk received her powers when she was exposed to gamma radiation during a blood transfusion from Bruce Banner. This caused her to transform into She-Hulk with superhuman strength and durability.
Photon acquired her powers in a rather complex way in the comics. It involved a combination of a rare celestial alignment and her exposure to a mysterious substance during a top-secret research project. This combination triggered a transformation within her, bestowing her with the powers associated with photons.
