Nascour (Japanese: ジャキラJakira) was thought to be the head of Cipher. A man with a terrifying visage, he is gaunt, dressed in dark clothes and possesses wiry, white, serpentine hair. He is the only character in the games to have the Trainer classCipher (Japanese: シャドーShadow).
Nascour's strategy in battle is to use X Special and other stat-enhancing items on his Pokémon.
Nascour first met Wes and Rui at Phenac City. Nascour was leaving Mayor Es Cade's home. No explanation was given at the time as to why he was there, although it is implied that it was to report to Evice. He promised Wes that they would meet again soon. He spoke truly.
Throughout the rest of the Shadow Pokémon incident in Orre, Nascour gave orders to the Cipher admins - Ein, Dakim, Miror B. and Venus. He is seen in a cutscene speaking to Miror B., Ferma and Reath via video conference at Miror B.'s Hideout, and later in a similar discussion with Venus and Ein at Venus's studio in The Under.
At Realgam Tower, Nascour forced Wes to battle against four Trainers in a row, without a rest. He then fought Wes himself, in front of a packed stadium of witnesses. However, Nascour failed to defeat Wes. He then revealed that he had been taking orders from Es Cade, who now called himself Evice, all along.
Nascour is presumably arrested along with Evice in the finale of Pokémon Colosseum.
"Good. The others also appear to be doing their parts to implement our plan. Our Shadow Pokémon is falling into place quickly. The final phase is not far off."
"Save your dancing until our plans succeed. I'm off."
Trivia
When battled, Nascour is the only Trainer to have no battle music play, however, during the battle the crowd can be heard cheering him.
In the game, Nascour has red eyes, however in the manga adaptation his eyes appear normal.
