The Rising Volt Tacklers work together to battle Entei after finally tracking it down.

Liko and the others return to the Paldea region in search for more information on Entei, and go see Pokémon League chairwoman Omodaka to get permission to enter Area Zero of the Great Crater of Paldea. However, the condition Omodaka sets is that they need to win a Pokémon battle against her...?! It's time for Liko, Roy and Dot VS Omodaka! How will Liko and the others take on the Top Champion?!

Liko and the others have come to Area Zero, where they accompany Briar to the place where Entei was spotted. In the meantime, Sango, who had been tailing the group, encounters an odd-looking Purin, and the two of them decide to team up to fight back against the enraged Paradox Pokémon Great Tusk after getting attacked by it?!

Liko and the others finally locate Entei in Area Zero! However, this Entei seems kind of different from normal Entei. Liko, Roy and Dot challenge it to a battle, getting help from Friede as well, but moves that should be effective against a Fire type like Entei aren't having much effect either?! But why...? And will Liko and the others manage to overcome Entei?

The Black Rayquaza once again appears before Liko, Roy and the others, and they all challenge it to a battle together in order to gain its approval! However, despite incorporating the terrain to great effect in their combo attacks, they gradually end up driven against the wall by the overwhelmingly powerful Rayquaza! Liko's wishes... Roy's desire... What's going to happen to them at the end of this fierce battle against the last member of the Six Heroes?!
