Chuck was up next and sent out Ariel, his Primarina, whom he had swapped her signature Z-Crystal, for the Fairium Z he recently received.  As soon as the battle started, it was over.  Chuck activated the Z-Ring and unleashed a Moonblast-powered Twinkle Tackle, knocking out the Kommo-o in a single massive hit.  Chuck gave the Totem a Full Restore and received his Dragonium Z and stepped down to let Jen take the Totem on.
