Once a renowned scientist, Dr. Kalamarus was transformed into a cephalopod after an experiment had gone wrong. In place of his legs were several tentacles, and he grew to hate all of the creatures living in the sea. He spent his time traveling the ocean depths searching for revenge, while also searching for buried treasure to add to his collection. When Max teleported nearby, Kalamarus relished the thought of taking his anger out on one with a backbone. He sent his minions, the Attack Squids to battle Max, but the boy was too agile for them, and they wrapped their tentacles around each other. Kalamarus then decided to attack Max himself, and used his Aqua-Blaster to shoot lasers rapidly. When this failed, he used his Electro Manta, but Max had already gotten to Kalamarus' shark submarine and discovered that Kalamarus stole treasure from wrecked ships. Kalamarus, refusing to let him escape with his secret, threw his trident at the Mighty One, but missed and hit the Aqua-Blaster, causing the entire ship to explode. Kalamarus, trapped in the jaws of his shark-shaped ship, screamed in agony as he sank into the ocean.
