The fishman is a creature that escaped from a laboratory, one of two successful escapes. It has a deformed snake-like tail, smooth face with black eyes, no nose, and a mouth stretching to its ears. It can transform its upper body to resemble human females, including mimicking Lance's appearance. It uses sound waves and illusions to court or attack. It has blue blood and was defeated by Lance in combat. The fishman felt jealousy towards Lance and understood the difference between beauty and ugliness after seeing him.
