Yes, this. Good idea.Zorro. You need an area at the limit of one culture's sphere of influence, with an existing cultural group previously in place. Zorro rights wrongs, foils plots. He is obviously from the distant culture-group but his deeds tend to aid individuals from the local group.

A good-hearted highwayman/freedom fighter is a great theme, though not only in the Americas, but its a common trope of American fiction.
