Gamma Radiation Enhancements: Doc Samson possesses great superhuman strength, endurance, and resistance to injury. The gamma radiation that transformed Doc Samson fortified his cellular structure, added roughly two hundred pounds of enhanced muscle, bone, and connecting tissue to his body, and turned his hair green. (The source of Samson's added mass is unknown, but probably extra-dimensional.)

Superhuman Strength: While not exposed to as great a dosage of gamma radiation as the Hulk, the Abomination, or even the She-Hulk, Samson was granted great superhuman strength. As a result of his gamma ray exposure, he possessed sufficient superhuman strength to lift about 70 tons. Samson's strength doesn't fluctuate with surges of adrenaline during periods of heightened emotional states, such as the Hulk does while angry,and as a result he is far less powerful. His strength was dependent upon the length of his hair. The longer it was, the stronger he was. His great strength also extends into the powerful muscles of his legs, allowing him to leap great heights and distances, though far less so than the Hulk or Abomination. Samson has been known to leap approximately 580 feet straight up into the air, and to a maximum reported distance of 910 feet. His strength no longer depends on the length of his hair, but it may still be affected by it.
