Can we expand this to include movies? If so, Sybok from TFF. I know a lot of people don't like that movie or the character, but Sybok is a really interesting character. We get a unique interpretation of a Vulcan who is emotional but is not given to the wild, unrestrained behavior that occurs without the disciplines of logic. Sybok is intelligent and charismatic, if ultimately misguided, so you can see why people would follow him anywhere.
