Benny Wolcomb is an oddball, who has the worst of both worlds. He can't utilize blight tokens, so he doesn't bring much to Plague. Plague also doesn't provide enough markers for his rat engine. He doesn't bring much to Bandit either - his Plague abilities become useless and he's more of a melee model with no interesting abilities. He has access to more markers and can turn rats into new enemy scheme markers, but other same costs bandits have more juice. And this guy is a Henchman, who can theoretically be a leader with 2 keywords.
