Nutsy is a vulture who serves as a member of the Sheriff of Nottingham's "brute squad".  Unfortunately, he's not terribly smart, and ends up bumbling his way through life and generally screwing up his superiors' and cohorts' plans in spite of his good intentions, including those of his buddy Trigger.  Nutsy generally wields a large halberd as a weapon of choice, and wears a purple hooded cloak.  He speaks with a southern American accent. 

Origins of the character: While there is no foundation for the character of Nutsy in the Robin Hood legends, the Sheriff of Nottingham did have his own guards and enforcers.  Nutsy, therefore, is pretty much an original character specific to this movie.
