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.
It is unknown if "Toon Sheik" may refer to Tetra, as Sheik has never been depicted in a Wind Waker-influenced artstyle. It is possible that the developers were planning on designing a new Sheik model, similar to what was done with the regular version of the character in Brawl.
