The Deep Dweller was an, as the title implies, deep-sea-dwelling that was forced to the surface, where it became disoriented by the light and began to attack passing ships. It soon attracts the attention of H.E.A.T., who eventually tried to lure the Dweller out of the Hudson Canyon and off of the continental shelf. After a battle with Godzilla, they are able to use light beams to send it home, but they become caught on it and are dragged into pressures that their submarine cannot handle. Godzilla then burrows out of the shelf and breaks them free before again confronting the Deep-Dweller. He then allows the Fish to swim away into the open ocean.
