Underdog Man

Underdog Man (カマセイヌマン, Kamaseinuman) is a series of remotely-controlled robots created by Child Emperor. They assist Child Emperor during his battles against various monsters.

Appearance
They appear as dog-like humanoid robots and an individual can be easily mistaken as a real hero.

When 3 Underdog Men combine they take on the appearance of a three headed muscular humanoid beast. Each head has a spiky collar which is tied together with chains and a belt.

Monster Raid Arc
Child Emperor uses it to fight the monster Eyesight and to save the poisoned heroes. After being bitten by Eyesight's poisonous snakes, Child Emperor collects the data and sends it to the Hero Association to create an antidote. Underdog Man No. 22 then grabs Eyesight and self destructs.

Underdog Man No. 23, No. 24 and No. 25 are deployed to battle G5. They combine into their more powerful form and fight G5. With Child Emperor's pencil missiles, the hero buys enough time for him and Waganma to escape. No. 23, No. 24 and No. 25 are his last remaining Underdog Man robots.
