Marvel Team-Up #14
Mayhem Is... the Men-Fish!
While web-slinging across the city, Spider-Man is suddenly drawn to a trench-coated man who is attacked by muggers, but easily fights them off. When it's revealed to be the Sub-Mariner, the two engage in a brief battle, which is interrupted by the escape of a ship out into the ocean. Namor explains that he was tracking down Tiger Shark, the man responsible for killing his father. Spider-Man agrees to help Namor track down Tiger Shark and bring him to justice.
Meanwhile, Tiger Shark has once more allied with Dr. Dorcas, who has been developing men-fish called Aquanoids to be his army of aquatic mutates. When Namor and Spider-Man arrive on Dorcas' ship, the two fight off both Tiger Shark and Dorcas' Aquanoids. Winning at first, the two heroes are soon drugged and restrained.
However, before Dorcas and Tiger Shark can dispose of them, Spider-Man causes water to flood into the ship, renewing Namor's strength. Breaking himself and Spider-Man free, they quickly defeat the Aquanoids and Tiger Shark. However, they are forced to abandon ship when devices within the ship become unstable. Getting to safety, the two watch as Dorcas' vessel explodes, seemingly killing Tiger Shark and Dorcas in the process. With the battle over, Namor feels that his father's death has been avenged.
