As they head to Mount Coronet together, alternate Ash and Dawn note the suits of armor alternate Goh and Chloe are wearing. They explain that, after noticing how Team Rocket's Pokémon weren't being rewound, alternate Chloe hacked into their database and constructed them and their Pokémon the same kind of suits the villainous team had to protect them from the time reversal.
Ash and his friends find themselves in an odd, dark dimension, where they immediately find Dialga and Palkia locked in a fierce clash and opening Gates in the process. Before they can do anything to stop them, alternate Team Rocket appears before them and sends out their Pokémon. Ash and Goh do the same, but the time reversal immediately causes all of their Pokémon to revert into Eggs.

Reacting to the group's desperate pleas, a shining image of Arceus appears from the Red Chain and makes it disappear, finally stopping Dialga and Palkia's fight.
