You've managed to stop the rampage of Palkia and Dialga. However, your story wasn’t over quite yet. You return to the Temple of Sinnoh, and there stood Volo.

"Oh, right. You must be wondering where the last plate is."

He pulls the final ancient plate you needed out of his bag, giving you an evil smile.

Volo rips off his merchant attire, revealing his outfit similar to Arceus, a white toga with yellowish gold outlines, green pants, golden sandals, and a necklace similar to Cynthia’s brooch.
