Silva

Silver (Japanese:  ???) is a young man from Pyrite Town who is widely considered as Duking's best friend, lieutenant, and right-hand man.

Brave, loyal, but more than a little foolhardy and luckless - Silver attempts to fight Cipher throughout Pokémon Colosseum but has little luck.

When Mirror B. kidnapped Duking's Plusle and used it to intimidate Duking into letting Cipher have free run of the town, Silver made a rescue attempt.

Silver snuck into Mirror B.'s Hideout, but was eventually thwarted and injured by two of Mirror B.'s lackeys. Silver was eventually rescued by Wes and Rui, who arrived in the nick of time.

Silver continued to investigate Cipher's actions in Orre, though. He later attempted to explore the Under, but was captured when he was mistaken for Wes. He was eventually freed after Wes liberated the Under from the control of Venus.

Silver later disguised himself as a Cipher security guard and infiltrated Realgam Tower.
