Keeby at first glace appears to be Kirby, only in yellow, but there is more to him than meets the eye.
Sakurai has stated that he wishes to add Keeby as a DLC character. He also states that Keeby is different than Kirby because he has a different name. Despite this, he says that Keeby will have the exact same moveset as Kirby.
Keeby is a highly requested character that people claim to want as DLC. The user ArcLordCarlisle even went as far as to say if Keeby gets in, he should have a White and Gold and Blue and Black alt.
