5. William Adama
Sometimes, Captain Adama was forced to make some really tough decisions as leader of the Battlestar Galactica. Occasionally, his style of leadership bordered on martial law. Be that as it may, he still managed to keep his people alive long enough to find a new home, and put an end to the conflict with the Cylons along the way. He even earned a promotion, as by the middle of the series, he was the Admiral!
