Woodsman

It was the woodsman's job to rush in after Red and her Grandma were foolish enough to be eaten by a wolf. He brandished his axe menacingly and cut the animal open, freeing the hapless females.

But he's new on the scene, not original to the story. Early on, Red saw through the ruse and made her escape. Or she dissected old Lupus her own self. Or never let him in to begin with, having built her Grandmother's house with bricks. Wait, that's wrong. In any event, it was her wits that got her through the ordeal, not an armed man-stranger who happened by.
