Child Emperor (童帝 Dōtei) is a S-Class, rank 5, superhero for the Hero Association. So far, he is the youngest hero in the Heroes Association.

Appearance
Child Emperor is a young boy with large eyes. He wears a plain T-shirt with two buttons both of which are buttoned, along with a black school bag on his back.

Personality
As a genius, the Child Emperor values education, which can be seen when he mentions about going to cram school even after hearing about the Earth being in danger. He easily becomes infuriated when being labelled as childish by others. He is very analytical, observing the situation and formulating plans in a calm and collected manner.

Alien Conquerors Arc
Child Emperor is first seen during the S-Class heroes meeting. After the Dark Matter Thieves attack A-City, Child Emperor suggests that the Hero Association should confirm who the enemies are and whether they are what the prophecy was referring to. He later goes to the roof of the Hero Association HQ with Genos, Superalloy Darkshine, Tatsumaki, and King. He immediately starts thinking about ways to take care of the spaceship, while Bang, Metal Bat, Atomic Samurai, and Pri-Pri-Prisoner take care of Melzalgald. Afterwards, Child Emperor appears beside Genos and Engine Knight.
