Frog Man is an artificial mutant of the House of Evolution, engineered by Dr. Genus and shaped like a humanoid amphibian. He joins a squad tasked with capturing Saitama, gets brushed aside, and is later torn apart by Beast King.
Frog Man takes the form of a humanoid amphibian with bulging eyes and a scar cutting across his face. His throat and belly are white, while black spots dot his back and arms. He dresses in black trousers and sandals, wears a pendant around his neck, and carries the character for rearguard inked on his left shoulder. A broad belt holds a tanto at his side.
He nursed a grand ambition to wipe out the whole of humanity, and he took special pride in the short blade he intended to carry out the deed with.

Naruto vs Luffy with the twist nobody asked for: Luffy tickled Hinata on date night, and she kind of liked it. We break down the whole fight and commit to a winner....

There are no women on Namek. That isn't an oversight, it's the biology. Why we handed Piccolo the one thing his own species rules out, and why it had to be trap soul....
Assembled by Dr. Genus, Frog Man rides with the House of Evolution team dispatched to seize Saitama. After Kamakyuri falls, Saitama and Genos step out of the apartment, and Saitama drives Frog Man and Slugerous headfirst into the ground up to their waists. He resurfaces during Saitama's clash with Beast King, only to be shredded by one of the beast's attacks. Because he was beaten so quickly, little of his fighting prowess ever came to light, though his choice of a tanto hints at some skill with a blade. He also turns up as a playable fighter across several One-Punch Man video games.
