"You've met with a terrible fate, haven't you?"
I've wanted to play around with this idea for a long time now, and I had a ridiculous amount of fun with the concept.
The basic idea is that instead of recovering the Ocarina of Time and regaining his true form, Link remains trapped in Deku form...but Majora's curse is slightly fractured, perhaps unable to fully compete with the power of the Triforce of Courage. As Link matures, his true features merge with those of his cursed body, and he becomes a nightmarish vision of Deku meshed with Hylian, resembling some dungeon-crawling wraith rather than the Hero of Time.
Scary antihero Link YAY~
Link, Majora, the Deku, and all things Legend of Zelda belong to Nintendo.

Have fun trying to steal Link, guys. Lemme know how that goes.
