Siebold used his Blastoise in his battle against Alain and his Charizard. Alain Mega Evolved his Charizard into Mega Charizard X and it used Dragon Claw. Blastoise used Hydro Pump to counter Mega Charizard X but Mega Charizard X was able to dodge the attack. Blastoise then used Skull Bash, clashing with Dragon Claw. Siebold then Mega Evolved his Blastoise into Mega Blastoise. Mega Charizard used Steel Wing and Mega Blastoise used Dragon Pulse, badly damaging Mega Charizard X. Mega Blastoise then used Hydro Pump but Mega Charizard X was able to withstand the power of Hydro Pump. Mega Blastoise used Power-Up Punch and Mega Charizard X used Flamethrower. Both attacks clashed with each other. Mega Charizard X used Dragon Claw, hitting Mega Blastoise. Mega Blastoise then used Dragon Pulse once more, hitting Mega Charizard X. Dragon Pulse was enough to defeat Mega Charizard X due to its Mega Launcher ability.
Lysandre explained to Alain all the battles he had with trainers that wielded Mega Evolution was to collect the energy required to control Zygarde.
