Captain Barracuda was a modern-day pirate who tried to board a city cruise ship, which happened to hold Iceman, the Human Torch, and Dorrie Evans as its passengers. He was defeated by the two heroes and arrested after he crashed his ship into an iceberg created by Iceman.^[1]

Barracuda reappeared later, capturing Namor the Submariner and Karthon the Quester who were fighting for the Serpent Crown. Barracuda took the crown for himself, but was again defeated when he stole a sonic device that attracted a torpedo into his own ship.

He survived and has since clashed with both the Fantastic Four (when he stole the horn which the Sub-Mariner used to control sea monsters and used it to attack New York)^[2] and the Hulk. During one of his later appearances, he was defeated this time by Hawkeye and Deadpool.^[3]

Captain Barracuda eventually replaced his crew with Robo-Buccaneers of his own creation. During a confrontation with Stingray, who had uncovered Barracuda's caviar smuggling ring, Barracuda's ship was approached by a submarine piloted by Machinesmith, a member of the rising A.I. Army. Using an Un-Inhibitor, Machinesmith freed the Robo-Buccaneers from Barracuda's control. They all defected, leaving an astonished Barracuda to fight Stingray on his own.^[4]

He is a skilled leader, a proficient thief and talented in both conventional and advanced firearms. He is also an expert seaman and commandeered two submarines armed with many high-tech weapons.

Since he can only see with one eye, his depth perception is greatly hindered.

The first submarine he commandeered had an electrified metallic net to ensnare prey, a cannon which fired an inertia-ray strong enough to down an American bomber by instantly ceasing its forward motion, and had one torpedo fitted with an atomic warhead as well as explosive shells. The second submarine, stolen from Captain Omen, could fire explosive shells too. Besides, Barracuda usurped control of Omen's former base complete with its own power plant, laboratory and mini-sub. He had possession of an omni-directional beam also known as the Sonic Magno-Directoid which was a military device that could control the course of underwater weapons, and a machine which was intended to stimulate cell growth using a gamma-ray power source to generate neurogenic rays, making wounds heal faster, but when its power source fused several circuits together, the machine instead rearranged cells, devolving human beings into ape-like beasts. He also possessed legendary relics like the Horn of Proteus which could summon and command sea creatures, and the Glove of Asteria which was able to direct a destructive column of air moving at nearly light speed.
