Groudon appeared in its Primal form, walking through the sea and looking for the megalith. It later encountered Kyogre and started to battle it. Both of them gave a though battle. Alain then interrupted the battle with his Mega Charizard X and Groudon used Solar Beam at Charizard, which Charizard dodged. Steven Stone also used his Mega Metagross to help Alain and Charizard out. Groudon continued the battle and was able to damage Charizard badly with Precipice Blade. Rayquaza later appeared in its Mega form and both Groudon and Kyogre attacked Rayquaza with several attacks. Rayquaza was able to finish both Groudon and Kyogre off with Dragon Ascent and Groudon and Kyogre both returned back into their normal form.
Sawyer remembered how Steven's Metagross battled against Kyogre and Groudon, who wanted to obtain the megalith, which may not have been destroyed after the recent battle.
