The Struggle for Time and Space Begins Again...! The Legendary Arceus.
Long ago, Arceus granted a fragment of its awesome power as the Jewel of Life to help Michina Town in its hour of need, only to be betrayed when it was time for that power's return. Now, Arceus is about to return to reclaim its stolen power - vengeful and seemingly unstoppable. Not even the combined might of Dialga, Palkia, and Giratina can stop Arceus from devastating existence across multiple dimensions. But Ash and his companions may have discovered a way to redeem that ancient betrayal. Will there be time to return the Jewel of Life before Arceus destroys everything and everyone they've ever known?
