Unicornfish

Unicornfish is a student at Silvershoal High. They are ostensibly a member of the track team, but they never actually participate in meetings. Instead, he sits on the sidelines or lurks in the shadows in hopes of intimidating Mudskipper

Unicornfish is very lonely. His father was always distant, and he never knew his mother. They essentially had to raise themself. Damselfish was the only fish who ever got close to them. As a result, they're very protective of him. After Mudskipper usurped her place as the star of the track team, Unicornfish vowed to get revenge. Despite being quiet and reserved, they can be vicious. He does whatever he can to sabotage Mudskipper, but his target always seems to be able to escape from traps unharmed. Mudskipper is still oblivious to the fact that Unicornfish hates him with every fiber of their being.
