Brave Giant

Brave Giant is a very powerful robot designed by Child Emperor. It is his ultimate weapon and his trump card, although according to Child Emperor, it is still a prototype.

Appearance
Originally, Brave Giant was a large white robot with a smooth and towering appearance. He had three fins coming out of his forehead, and there were several lights placed around his body. However, Murata decided to change the design as well as redo Chapter 99.

In the final updated version of Chapter 99, Brave Giant has many more parts added to him and has more jagged ends on his limbs. Brave Giant now has two pairs of eyes and four fins protruding out of his head in a backwards fashion. There are also several blades and such popping out of his shoulders, as well as on his ankles, knees, and waist. On his back there is a large backpack, mimicking Child Emperor's own backpack, and inside it are large jet propulsors, wings, and rockets that allow Brave Giant to fly at high velocities and shoot multiple different weapons.

Monster Association Arc
After Phoenix Man is resurrected and Child Emperor realizes his new and dangerous strength, the hero clicks his watch and summons the parts of the Brave Giant which are situated around the Monster Association Headquarters. Once Brave Giant is summoned, it swats Phoenix Man across the room, and the two begin their second battle. As the two of them do battle, Phoenix Man realizes that Child Emperor is rushing to finish the battle and realizes that there must be some limitations to the Brave Giant and that he can only operate it for a limited time. His hypothesis is correct, as Child Emperor laments that Brave Giant can only operate for 2 minutes and 38 seconds before its energy becomes uncontrollable and it self-destructs.

As the two continue their battle and unleash their respective special moves and combos, Child Emperor manages to trap Phoenix Man in a very strong electromagnetic web and punches him with his Giant Knuckle Sandwich. A struggle ensues, with Phoenix Man appearing to overpower Brave Giant, but Child Emperor then activates overboosters and releases output limiters. The energy from the punch finally overpowers Phoenix Man and destroys the floor, sending both warriors falling into water. Upon touching the base of the ground, Brave Giant's lights turn on and Child Emperor is shocked to see the corpses of several monsters littering the floor. Suddenly, a bright burst of energy is unleashed, knocking the Brave Giant back.

Abilities and Powers
Being the trump card of the S-class genius Child Emperor, the Brave Giant is an extremely powerful and useful weapon, dwarfing all of Child Emperor's other machines in might. With Brave Giant, Child Emperor is able to go toe-to-toe against a Dragon-level mysterious being and when unleashing its full power, is able to temporarily knock out said mysterious being. Unfortunately, Brave Giant can only be operated for 2 minutes and 38 seconds before the energy core will no longer be controllable and will self-destruct, significantly limiting its capabilities.

Physical Abilities
Immense Strength: Being a large mecha and Child Emperor's trump card, Brave Giant is immensely strong. It is able to effortlessly smash through multiple stone pillars and destroy an entire floor of the Monster Association headquarters. It was able to combat resurrected Phoenix Man's immense strength and once it unleashed its full power, it actually managed to defeat the Dragon-level monster and temporarily knock him out of commission before he resurrected again.

Immense Speed and Reflexes: Despite its large size, it has surprisingly advanced speed, being able to keep up with the dragon-level monster Phoenix Man and launch multiple speedy-quick attacks.

Immense Durability: Brave Giant's advanced body and sturdy exterior allows him to defend against searing attacks from Phoenix Man, and his Divider Shield was able to withstand the multiple '''Phoenix Homing Wing Attacks. '''Additionally, it was still operational after releasing all of its output limiters and unleashing its full power.
