He is an enlarged catfish with muscular human arms and legs. He has an electric field emitted from his body.
Unlike most other monsters in the association, he appears to have an understanding of the limits of his strength. Additionally, he gave most of the credit of his victory to Gyoro Gyoro and its decision on who he would fight, instead of boastfully taking all of the credit of his victory like most monsters typically would, demonstrating a less arrogant side.
