Gyoffrey (ギョフリー, Gyofurī) was a Mysterious Being and a member of the Monster Association. He was killed by Tanktop Master.[1]


Gyoffrey looked like a giant, fat fish with arms and legs and a grass skirt.


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


Human Monster SagaEdit

Super Fight ArcEdit

Gyoffrey 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.[2]

Abilities & Powers Edit

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


  • The Gyo in his name means fish.
