As he knocked Charizard back, Seiya immediately evolved into Vaporeon on the spot and followed up with a Hydro Pump.
Compared to the Normal-type Swift, the Water-type move Hydro Pump was obviously far more effective against the Fire-type Charizard.
As Charizard took Seiya's Hydro Pump, it let out a pained groan and was blasted more than ten meters away.
"Just as the rumors said, you can freely evolve into all sorts of evolutionary forms.
"And against a Fire-type Charizard, you even know how to use type advantage to gain the upper hand. I really can't underestimate you.
"But even so, we won't admit defeat just like that. Show him our true strength, Charizard!"
As if it had heard Alain's call, the Charizard that Seiya had sent flying with Hydro Pump rose to its feet once more and raised its head in a roaring response.
At the same time, the Mega Stone around its neck and the Mega Stone on Alain's wrist both shone with a brilliant light.
"Respond to my heart, Key Stone."
"Surpass evolution—Mega Evolution!"
Dazzling light burst from the Mega Stone on Charizard's neck and the Key Stone on Alain's wrist, quickly forming a chain that linked them together.
When the bond between Trainer and Pokémon reached its limit, Alain's Charizard began to change as well.
Charizard had two Mega Evolution forms: Mega Charizard X and Mega Charizard Y.
After Mega Evolving, Alain's Mega Charizard had grayish-black skin all over its body, while the flames by its cheeks and at the tip of its tail turned blue. It was Mega Charizard X.
Compared to Mega Charizard Y, which looked more like the original Charizard, Mega Charizard X had enhanced Special Attack, and its attributes gained Dragon Attribute in addition to its original Fire Attribute and Flying Attribute.
"Roar—!"
