The Beginning of the End with Kyogre & Groudon VIII/VS Kyogre & Groudon VIII or Battle As One (Japanese: VS カイオーガ & グラードン VIIIVS Kyogre & Groudon VIII or 戦う意志のもとにBattle As One) is the 244th round of the Pokémon Adventures manga.
On top of the wreckage of the Submarine Explorer 1, a startled Amber wakes up. He remembers the last words Archie told him before locking him in the Submarine Explorer 1 and sending it to the bottom of the water. Amber immediately shakes it off as a misunderstanding and goes to help his teammates raise the sea level.
Elsewhere, Blaise and Tabitha continue traveling on Route 121, where they are joined by Courtney. At Groudon's location, it continues to easily overpower Brawly and Roxanne with its attacks. After defeating Brawly's Machoke, Groudon attempts to leave the battle. Roxanne immediately stops its movements with her Nosepass's Block. Although not her style of battling, Roxanne has her Pokémon continuously attack Groudon, preventing it from fighting back.
Suddenly, a voice from above praises Roxanne's skills and sends out a Sealeo to attack Groudon with Ice Ball. The voice is revealed to be that of Wallace, who came to help them stop Groudon. Before they can continue, three figures arrive and tell the Gym Leaders that if they intend on stopping Groudon, they'll have to face them first.
