The three Pokémon on the battlefield were fighting more fiercely by the moment.
The entire sky had become their battlefield. Alongside unleashing all kinds of moves, head-on clashes at close range were gradually becoming their main means of attack.
In fact, it was clear that Rayquaza was slightly stronger as an individual.
Especially with Dialga and Palkia already injured and attacking each other in their hotheaded state, Rayquaza had been able to demonstrate its strength, darting back and forth to gain a slight upper hand.
But that slender advantage could not bring the battle to an immediate end.
Under normal circumstances, or somewhere else, Xia You could have leisurely let Rayquaza keep fighting like this to hone its combat skills. But the situation had changed, and he could not afford to delay any longer.
Two short whistles and one long one rang out from the Gengar Mask, echoing through the sky. Even in the midst of fierce battle, they immediately caught Rayquaza's attention.
Knowing this was its signal for communicating with its Trainer, it abandoned Dialga and Palkia without hesitation and returned to the vicinity of the Space-Time Tower's summit.
Rayquaza's departure naturally drew the other two Pokémon's attention, and almost instinctively, they gave chase!
But just as Rayquaza returned to the tower's summit, before the other two Pokémon arrived, Xia You spoke.
"Use that move!" he shouted. "Use Dragon Ascent!!"
As soon as Xia You finished speaking, Rayquaza roared, and in the next instant, its body underwent a sudden change!
A dazzling emerald light abruptly enveloped Rayquaza's entire body, which began changing shape and growing in an instant!
In no time at all, wrapped in green light, an entirely new Rayquaza-longer, larger, and fiercer than before-appeared high in the sky!
Mega Black Rayquaza made its dazzling entrance!
