Gyoffrey

Gyoffrey (ギョフリー, Gyofurī) was a Mysterious Being and a member of the Monster Association.

Appearance
Gyoffrey looks like a giant, fat fish with arms and legs an a grass skirt.

Personality
Gyoffrey is a sadistic and selfish monster trying to take credit from the other monster and crushing an already wounded Mumen Rider.

Super Fight Arc
He is seen overwhelming Mumen Rider and prepares to kill him, but is stopped by Tanktop Master and is launched out of the hospital, killing him in the process.

Power
Given his status as a mysterious being and the fact he was able to ruffle up Mumen Rider, it could be assumed he has very basic power. However, he is still very weak compared to several other mysterious beings, and was knocked out in a single tackle by an already critically wounded Tanktop Master.
