"Groudon is one of the Chaos beasts. They are creatures of mass destruction with limitless amounts of them. So, to combat these beasts, Arceus made guardians to keep them trapped, and to battle them when they escaped. Groudon was trapped by a land beast set to keep order. However..." "What?" "Let her finish the story." "Sorry." "This beast could not fight on its own. It resides under where Groudon rests in the volcano, keeping it trapped. But, trapping it uses too much energy. In order for it to awaken and trap Groudon, it needs something crucial." "What's that?" "The prayers of other Pokemon. However, we must be quick. If Groudon reaches the Red orb which rests dormant in a temple under the sea.... Nothing will be able to stop it."
