The King of the Elements mobilized the water element, and the Power Stone's power awakened Gyarados's potential.
The black aura emanating from Gyarados suddenly flowed back into its body, washing over its heart again and again. Gradually, extensive black markings appeared across its heart.
At that moment, Gyarados suddenly roared on the battlefield, and its body began to change.
Gyarados's body grew stronger, its yellow belly turned black, and the three horns on its head grew longer and turned black as well.
Its typing also changed from Water and Flying to Water and Dark.
Lin Guang saw that all the changes in Gyarados stemmed from the mutation in its heart, which had allowed it to complete its Mega Evolution.
"The battle has only just begun!"

"Horn Attack!"
At Giovanni's command, Rhyhorn instantly charged forward. This time, Giovanni intended to finish off Lin Guang's Gyarados with this single blow.

"Rhyhorn is unable to battle!"
