Doc Samson is a character in the Marvel universe. His real name is Leonard Skivorski Jr, appearing primarily in The Incredible Hulk comics. He worked alongside Bruce Banner as a psychiatrist, and exposed himself to some of the gamma radiation that created the Hulk. As a result, he received superhuman strength and a muscular physique, as well as long green hair. Like his namesake, his power depended on the length of his hair.
