Tin Woodman
In "The Wonderful Wizard of Oz", the Tin Woodman tells Dorothy Gale and the Scarecrow that the lady was a servant for an old woman who did not wish her to marry, and so sought the aid of the Wicked Witch of the East to place a spell on him that caused him to cut himself up with his axe while carrying on his livelihood. In "The Tin Woodman of Oz", this was retconned, and in Nick's new telling, she was directly enslaved by the Witch herself.
