Submariner — Sea Life

The Reaper Aquatic is a mechanical deep-sea predator said to appear when something beneath the ocean is supposed to die—but refuses to. Its pale skull-like head sits beneath a black armored hood, while a corroded copper-and-steel body conceals pumps, gears, pressure chambers, and an artificial circulatory system filled with glowing blue coolant. Most unsettling is the enormous scythe-shaped dorsal appendage sweeping over its body. Sailors originally assumed it was decorative until damaged submersibles began returning with long, perfectly curved cuts through their hulls. According to Submariner lore, the Reaper Aquatic doesn't hunt living creatures for food. It hunts machines, wrecks, and unnatural things that have remained underwater too long.
