Colonel Silver

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. 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 monkey's that Goku befriended lived in. Silver was 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 destroy him. In the manga, Silver was executed.
