Seeger the Unstoppable was one of that rarest of heroes: a Disco Bandit pacifist. They called him "the Unstoppable" because he never seemed to do anything that needed stopping, and so therefore they couldn't.*

That doesn't sound very legendary, I'll grant you, but Seeger was in fact one of the men who brought music, and the banjo in particular, to the banditing community, transforming a rabble of thugs and highwaymen into a (somewhat) organized collective of music aficionados (who incidentally also liked to beat people up and take their stuff).

*Maybe if anyone had ever given him that hammer like he kept hinting at, things would've been different.
