Bluno (Japanese: ブルーノBluno) is a Cipher Peon who appears in Pokémon Colosseum. He is first encountered at the Mayor's House in Phenac City along with Verde, Rosso, Miror B., Folly, and Trudly. Leaving Wes to Folly and Trudly, Miror B. departs for Pyrite Town. Upon beating Folly and Trudly, Wes exits the Mayor's House to find the three Peons blocking the exits to the city. Bluno occupies the spot in front the city's main, southern entrance. Wes must choose one of the three Peons to battle. The other two run away and disappear for quite some time. If he chooses to fight Bluno, he will be known as a Mystery Troop member rather than as a Cipher Peon. If Wes snags Bluno's Shadow Croconaw, but loses all his Pokémon before the end of the battle, he may attempt to fight an alternate Peon, but they will not carry their Shadow Pokémon.
If Wes chooses to fight Bluno in Phenac City, he will appear for a rematch in Realgam Tower disguised as a receptionist behind the desk in the tower's casino. After he is beaten by Wes he vanishes and is not seen again.
Should Wes choose to fight Rosso in Phenac City then Bluno will not show up until after beating the game in Snagem Hideout.
Should Wes choose to fight Verde in Phenac City then Bluno will not show up until after beating the game in the Shadow PKMN Lab.
He is dressed uniquely as compared to most other male Cipher Peons. His outfit is a much darker blue than what the usual peon wears.
