10. Lando Calrissian
The epitome of cool, Lando Calrissian is a jack of all trades with skills in gambling, smuggling, card playing and piloting. He lead the fighter assault on the second Death star and struck the main blow that destroyed the station. He later became the administrator of several prominent mining organizations and periodically assisted the New Republic afterwards although he mostly focused on his business operations. During the Yuuzhan Vong War he designed and produced the YVH attack droids(essentially terminators) specifically to fight the Yuuzhan Vong. Calrissian doesn't get near enough credit for well he handles his dilemma on Empire Strikes Back. If he handled it any other way, lots of his customers probably would have died on Cloud City, he probably wouldn't have been in a position to rescue his friends later, and Luke would have been captured or killed by Darth Vader. If Calrissian hadn't kept his composure, the entire Rebellion probably would have met an early end which is more than enough reason for him to place this highly.
