Colonel Silver is a villain in Dragon Ball and an American member of the Red Ribbon Army, working for Commander Red. He was the first operative of the army Goku fights against in the desert region. A skilled boxer, he was seen defeating several professional prizefighters. When he first started to search for the Dragon Balls, he had to take out the forces of Emperor Pilaf to obtain the Dragon Ball he found. While looking for the next Dragon Ball, he had his men tear down a forest with monkeys that Goku befriended lived in. Silver then demanded Goku's Dragon Ball before being easily defeated in a fight against Goku during, mostly because he underestimated Goku, leaving his guard down. When the news of his defeat got out through the rest of the army, Commander Red sent him away for his failure and had the rest of the army look out for and kill him. In the manga, Silver was executed.
