Nick is first mentioned when an old Munchkin farmwife comes to Nessarose Thropp, the newly established Eminent of Thropp, also known as the Wicked Witch of the East, telling her that she does not approve of her daughter's sweetheart and asks her to enchant his ax so it would cut of all his limbs and kill him. Nessarose does this in exchange for two Sheep and a Cow, and this is one of her first steps to becoming wicked. Then, later it is learned that the Tin Woodsman that is traveling with Dorothy, The Scarecrow, and The Cowardly Lion is indeed Nick Chopper when he kills all of the Wicked Witch of the West's wolves. Nick's story connects back to the The Wonderful Wizard of Oz by L.Frank Baum the Tin Woodsman tells Dorothy and The Scarecrow about his backstory.

In the Wonderful Wizard of OzEdit
In The Wonderful Wizard of Oz Nick Chopper's name is not mentioned but the Tin Woodsman does tell Dorothy and The Scarecrow about how he became tin. He tells them that his axe had been enchanted by The Wicked Witch of the East at the behest of his lover's mother and had cut off every part of his body one by one. Then he told them that everyday he got a part of his body cut off he had a tinsmith fix it. Then eventually he was all tin. But one thing was not right. The tinsmith had forgot to put a heart in his chest and that is why he longed to have one. He is the title character The Tin Woodman of Oz and is eventually combined by a tinker with his Munchkin sweetheart, Nimmee Amee's other suitor into a creature named Chopfyt, who marries her.
