In the climactic showdown within One-Punch Man Volume 10, Child Emperor's strategic brilliance takes center stage as he unleashes his trump card, the formidable robotic suit known as Brave Giant, to confront the reincarnated Phoenix Man. However, what initially seems like a decisive move turns into a shocking twist as Phoenix Man effortlessly counters the mechanical juggernaut. The once-vaunted Brave Giant is brushed aside like a mere toy, leaving Child Emperor in a state of disbelief and vulnerability.

The psychological impact on Child Emperor is palpable as his unwavering confidence falters. Phoenix Man, seizing the opportunity, capitalizes on the situation and undergoes a transformative evolution, emerging as an even more potent and terrifying monster.

 Child Emperor, faced with an adversary who not only nullifies his most potent weapon but also evolves into a more formidable threat, must now confront the limitations of his intellect and technology. The narrative tension intensifies as the clever child hero grapples with the possibility of defeat, and the once certain outcome of the battle becomes uncertain.
