Synopsis for Aquaman: "The Poseidon Adventure!"
Aquaman, tormented by Mera's disappearance, abruptly encounters an Atlantean called Poseidon, bearing a trident and convinced that he is really the legendary god of the sea. The hero gives battle, but is overwhelmed by the newcomer's great telepathic powers, which force Aquaman and all sea creatures he commands to do Poseidon's bidding. Poseidon begins a war in New Venice against the surface men who pollute his "domain", but Aquaman deduces that his power emanates from a telepathic amplifier in his trident. He then sends a telepathic command to a dolphin to snatch away and destroy the trident, which it does, but the stress caused by the conflict between Aquaman's and Poseidon's commands kill the dolphin immediately thereafter. Aquaman defeats Poseidon in battle, but later mourns the dolphin and is joined by the other sea creatures in his grief.
