The battle reaches its climax in the Giant Chasm, where the player discovers Colress is working with Team Plasma to learn more about the capabilities of Pokémon, and that Ghetsis is planning to use Kyurem, the "empty" Pokémon that is left over from when Zekrom and Reshiram split apart hundreds of years ago, by filling it with his ambition to rule the world. After battling the Shadow Triad with help from the player's rival (receiving his Liepard back), the player enters the inner sanctum of the Giant Chasm where they find Kyurem and Ghetsis. N appears with either his Zekrom (Black 2)/Reshiram (White 2) to try to talk sense into his father Ghetsis, but N's legendary Pokémon is defeated by and fused with Kyurem, transforming it into Black Kyurem (Black 2)/White Kyurem (White 2), and forcing the player to battle it. After defeating Kyurem, it separates from N's Pokémon and the player faces Ghetsis, who is stunned that he has been defeated again. N tries to talk sense into him, but Ghetsis leaves, and N thanks the player for his assistance in defeating Team Plasma once and for all. After defeating Team Plasma, the player is finally able to battle the Elite Four and the New Champion of the Unova League, Iris, and win the game.
