>>18264195>BWAfter defeating N and Ghetsis, however, the game is not over, as there are further activities to be done. After beating the game, the player will return to their house and see his/her mother next to Looker, who will be disguised as the player's mother temporarily. He explains that he needs help rounding up the Seven Sages of Team Plasma that are hidden across Unova. Also, Route 11 and Marvelous Bridge open up, allowing access to Black City or White Forest, Undella Town, and Lacunosa Town. The player may also access Giant Chasm, within which Kyurem may be battled and captured. The routes surrounding these areas contain many Pokémon native to the other four regions. Alder himself may also be battled in proper Champion fashion.
Pokémon outbreaks will now occur across Unova's routes as well. Additionally, a series of strong windstormsB/thunderstormsW will occur across routes, indicating the presence of a roaming TornadusB/ThundurusW, which can be battled and caught. In Caitlin's villa in Undella Town, the player will encounter Cynthia, the Champion of the Sinnoh region. She will battle the player, remarking about the striking similarities the player shares with another young Trainer from Sinnoh.
>B2W2After the main plot of the game has been completed, many inaccessible parts of Unova, including the Skyarrow Bridge, will be unlocked. Further Pokémon not native to Unova will be available, and the legendary Pokémon ZekromB2/ReshiramW2 and Kyurem will reveal themselves to the player. When they are caught, the player will be able to fuse the Pokémon and change Kyurem's form at will.
