After you defeat Nascour, he hangs his head and apologizes. But to whom? I guess Nascour isn't Cipher's main boss. Mayor Es Cade from Phenac City comes in and reveals his true self—he is known as Evice, the secret boss of the criminal cyndicate Cipher! Fat, evil, insane, causes earthquakes when he jumps, but extremely tough to beat. Get ready for one final battle!
When he is defeated, Chief Sherles and Officer Johnson arrive on the scene to arrest Evice and Nascour. Duking and Silva will show up as well, along with Eagun and his Pikachu. So it's eight against two—not good odds. Evice tries to escape using his fancy helicopter—until a fireball in the air destroys it. So Evice's escape plans are ruined and Cipher is done for. But what of the fireball that destroyed the helicopter? It's Ho-Oh! It flies close to the Colosseum and flies away.
Enjoy the credits. You will be prompted to save. Now there are a few more Shadow Pokémon to snag. Remember the other two JohtoStarters?
