Electric Catfish Man was an enlarged catfish with muscular human arms and legs. He had an electric field emitted from his body. He had a tattoo of a battery emoji on his belly.
Unlike most other monsters in the association, he appeared to have an understanding of the limits of his strength. Additionally, he gave most of the credit of his victory to Gyoro Gyoro and the latter's 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.
He and Maiko Plasma go to attack the recently rebuilt D-City. At the city, they encounter Lightning Genji. Unfortunately for Lightning Genji, their attributes nullify his stun attacks. The monster pair eventually defeat Lightning Genji.
Monster Association Arc Edit
Back in the Monster Association, she and Electric Catfish Man are discussing their victory over Lightning Genji and remarking that it was thanks to Gyoro Gyoro and its carefully-planned choice of who they would fight that the pair won against the A-class hero.
Later, Electric Catfish Man alongside other Tiger level monsters, including Maiko Plasma, are attacking Puri-Puri Prisoner. When their attacks have no effect, they attempt to flee only to run into Vacuuma. Vacuuma tells them not to retreat, to which the monsters angrily ask him to fight the S-class hero in their place. Vacuuma agrees and subsequently consumes them all to gain their powers, signifying the death of Electric Catfish Man.
Abilities & PowersEdit
As a Tiger level threat, Electric Catfish Man was a threat for the lives of a great number of people. He was also strong enough to defeat an A-Class hero despite being only a Tiger-level threat thanks to the great type-advantage he had against Lightning Genji. Though, even after combined attacks with multiple other monsters against Puri-Puri Prisoner, Electric Catfish Man was unable to even damage the S-Class hero.
