It has been announced that Zelda, Princess of Hyrule, is the 20th playable person for the upcoming Super Smash game for the 3DS and Wii U. Like in Brawl, Zelda’s model is based off of her design from The Legend of Zelda: Twilight Princess. There is no information on her move-set, but screenshots seem to imply potential changes.
In this screen we can see the use of a knight, similar to those from Spirit Tracks when Zelda possessed one for the duration of the game. Could this be her new final smash?
As of now there is no information in regards to Shieks appearance in the game.
