This specific title is derived from a cancelled character design in parallel with Toon Link, who was scrapped out of Super Smash Bros. Brawl for unknown reasons. Nothing much is known about this character except that Toon Zelda will be able to transform into Toon Sheik, another cancelled character who was scrapped out of Super Smash Bros. Brawl. Toon Zelda possibly would have acted in the same manner as Zelda would.
