Captain Tristram Maurer founded Amnesty Bay in 1799 and was the local lighthouse keeper. His mysterious disappearance, along with the horror stories found written in his journals, lead to local legends about his life.
When Tristram was a child, his imaginary friends were strange creatures that only he could see. His friends had powers, though minor at first, their powers grew more violent as he grew to adulthood. He escaped into alcohol and to the sea but a shipwreck where he was the captain and sole survivor lead him to build the lighthouse on Amnesty island as a act of penance. Maurer intended to spend the rest of his life on the island. One day, he mysteriously vanished with no sign. His journals were filled with stories of storms no one remembered, crazy sea monsters, and weeping from fear that something was hunting him. The superstitious folk of Amnesty abandoned the lighthouse and legends spread about Maurer.
More than 200 years later, Maurer returned to Amnesty Bay. When a giant sea creature attacked and killed a local, Aquaman encountered the beast but the creature vanished. The next day, Maurer introduced himself, claiming that he and his monsters had become one and he was summoned back to Amnesty by a growing evil. The evil turned out to be Black Manta who had returned to Amnesty with his Mecha Manta robot, a gift from Lex Luthor and Perpetua. Aquaman enlisted Maurer, and together with Mera and Aqualad, defeated Manta.
- Transformation: Maurer can transform into a massive and deadly sea creature.
- Decelerated Aging: Maurer has been alive for almost 200 years, showing little to no signs of aging since he was corrupted by his monster form.
- Maurer is seemingly inspired by the real-life horror author H.P. Lovecraft. Like Maurer, Lovecraft is famous for his stories about tentacled monsters from the ocean, and both lived in New England.
