Toon Zelda & Sheik
Toon Zelda and Toon Sheik are two characters whom were possibly planned for inclusion in Super Smash Bros. Brawl. Though the characters do not appear in the final retail version of Brawl, hackers have discovered a character file package in the game that was designated for the two.
Some speculate that "Toon Sheik" may refer to Tetra, as Sheik has never been depicted in a Wind Waker-influenced art style. However, since Sheik had never been depicted in a Twilight Princess-influenced art style either prior to Brawl, along with the choice of the name used, it would seem more probable that the developers were planning on designing a new Sheik model, in the same manner as what was done with the standard version of the character in Brawl. Also, the fact that a Toon Link was made greatly increases the possibilities that a Toon Zelda/Tetra would be made. Also, Toon Zelda is the incarnation of the "normal" Zelda and there was never a part in the Zelda games with the toon characters, where she turns into Sheik, so it could be more possible that with Toon Sheik was Tetra meant. It may have been scrapped due to a lack of attacks for Tetra, data concerns, or lack of time.
