Outcast since then he met up with Eelutan who offer him a position on his crew. Boss Seagulton accepted and has remained loyal ever since. He is the second in command of Eelutan ever had a rampage and Sumriel is not around to calm him down.

Seamaffe. She was always bullied since she had to get a cybernetic neck at such a young age, this also resulted in her getting into a number of brawls with fellow seahorses. Her group kicked her out after sometime, she couldn't even bid farewell to her parents. After some travel, she met Boss Seagulton who thought she was a good addition to the crew, with Lord Eelutan permission she became an official member. She is the crew strongest her reckless fighter, though she isn't very smart so she is easily defeat before the fights ever begin.

Ratobster. A small fry who was never really taken seriously in the big sea, he is smart though he behaves like a child. Lord Eelutan found him in bad shape in an undersea cave while searching for food. Instead of eating him, Eelutan took pity on him and offer him a place in his crew. Ratobster agreed immediately as he became good friends with Boss Seagulton and Seamaffe. Sumriel and him often fight for Lord Eelutan attention however they do pranks together, so they are on good terms.

Sumriel. A small mermaid who has a calming singing voice thanks to the unique pearls she wears around her neck. The origins of these pearls is quite unknown, they allow a mute mermaid such as herself to sing beautifully. If they are ever removed them Sumriel will slowly lose her strength and die, though it can only happen if a powerful light style weapon cut the un-tearable black ribbon. She was a guppy when Eelutan found her and raised her as his own ever since. Only her songs can relax him, so he keeps her close at all times. Many have tried to steal her since she is quite rare, though they are always reduce to shreds by her friends before that happens. She is now as the "Monster's Pearl"
