Red Shoes and the Future

If you haven't watched Red Shoes and the Seven Dwarfs, I would highly recommend it. It's basically a snow white where the princes are different fairy tale characters; Authur, Merlin, Jack from Jack and the Beanstalk, Hansel, and Pinocchio.

Plot: This is after everyone gets their curse removed. Merlin sets off with an army to suppress some evil dragon thing, unfortunately it didn't go as planned. 95% of Merlin died during the battle. Luckily something saves him but turns him into a living weapon. A robot with absolutely no memory of his former life. He also can't speak.
