(Star Wars, Qui-Gon Jinn) Qui-Gon Jinn is feykin and nothing will convince me otherwise. The reason he couldn't appear as a human Force Ghost at the end of Revenge of the Sith wasn't because he hadn't learned enough, it was because human wasn't his true form! He is a shape-shifting Fey mutt with dryad, sylph, flower fey, and unicorn heritage. Evidence? Legend has it that if you kill a unicorn, you will become only half a man. Look what happened to Darth Maul!
actual canon evidence qui-gon jinn is otherkin right here folks ^^^
