In such a dark world as the Crypt, you need one light of unwavering optimism. We need a radio helmsmen, who would basicly take over the calls on ship PA, but he would have to be always happy in the hell hole. Even if the ship is getting its ass kicked, he would be more than happy to rebel rouse. Most people would hate him, and some may like him, but he would be happy with everyone, and think he is the grand king of friendship on the Crypt, cause everyone knows and listens to him.
Again just an Idea
