Child Emperor vs. G5

Child Emperor vs. G5 is the battle between the S-class hero Child Emperor and the demon-level mysterious being G5 from The Organization.

Prologue
After Child Emperor finishes vaporizing Sludge Jellyfish, Child Emperor and Waganma leave the room and begin walking through the corridors of the Monster Association headquarters. As they're walking through the hallway, Child Emperor tells Waganma that he could remove the Kero Kero mask. He takes the mask off, inhaling deeply as he does, and remarks that he is starving. Child Emperor takes out a nutritious jelly and gives it to Waganma, but reminds him they have to keep moving. Waganma realizes that the child is in fact the famous S-class hero Child Emperor and complains that it took them way too long to arrive. Child Emperor gives him a deathly stare, immediately shutting Waganma up and making him apologize.

Battle
The S-class hero looks up and notices the shadow of a figure coming from a nearby corridor. He takes out a radio-controlled sentry to go deal with the threat, knowing that he would have to be extra careful with Waganma around. Once the sentry reaches the threat, it fires a large burst of energy, but it does no damage, and it is swiftly destroyed. The figure is revealed to be G5. Upon realizing the intruder is a hero, he tells Child Emperor that introductions aren't needed, as he would swiftly destroy him. Child Emperor takes out a flute to activate one of his devices specifically designed for machine-type mysterious beings called Enemy Machine Disabling Device Bug Basket Kun. Upon playing the flute, four rockets come flying out of his backpack and lodge themselves into the ground, forming a square around G5. Wires shoot out of each of the rockets, creating a square barrier to trap G5. The device surges out electricity at G5, and Child Emperor explains to Waganma that the device is a cage of high voltage cables, while at the same time sending out signals forcing it to shutdown. Waganma is impressed and states that he wanted to bring the robot home with him. But to the utter shock of Child Emperor, G5 manages to effortlessly destroy the device with a swing of his sword. Now seeing the dangerous strength of this mysterious being, Child Emperor tells Waganma to stand back as he does battle with the demon-level machine.
