So, in Hyrule Warrios artbook, there's concept art for a character named Linkel who would have been Link's daughter:
I know this comment will get some hate, but I would fucking love if Nintendo eventually uses some variant of this idea in a Zelda game and she became a Smash Bros. character. I wouldn't want her to be a clone of Link, but be her own character who uses different items from the series (since, for whatever reason, Toon Link refuses too).
This is so outside the realm of possibilities, but I just love that art so damn much. A guy can dream, right?
EDIT: Also, she is sporting some fabulous boots...
