Shellshock was a flunky of Psycho-Man along with Ivan Karlovich and Live Wire; Psycho-Man kept them under control using his Control-Box. Psycho-Man intended them to guard his secret base in the Caribbean Sea, but the trio was defeated by the invading Inhuman Royal Family and Black Panther. Shellshock shot a hunter missile to track the Panther, but the Panther covered behind Shellshock himself, so that Shellshock was hit by his own slug.^[1]

When Shellshock left Psycho-Man's employ, he kept the weapon designed for him and teamed up with fellow former flunky of Psycho-Man, Live Wire. They attempted to steal Alicia Masters' statues, but were defeated by the Thing.^[2] He tried to get revenge on him when the Thing was hospitalized, but another superhero friend of the Thing stopped him before he could reach his bed.^[3]

Shellshock was later present at the Bar with No Name, and met his end there, thanks to the Scourge of the Underworld.^[4]

• Shellshock used a special handgun that fired assorted projectiles, including explosive projectiles, heat-seeking and guided projectiles, and an expanding yeast-putty which entangled opponents.^[1][3]
