Walden had been captured and placed in an aquarium where he was observed and mocked by others.. he grew a hatred towards humans, and whoever was on shift to tend to him, like feeding, he would try to drown them..

he was tired of it so much, he just only wanted someone who would care for him..

he had long blue hair, had a human body but, shark tail, it looked like how a mermaid would be like just with a shark tail instead, yellow skin, crimson eyes and a prosthetic arm..
