Most of the reasons for him NOT to be in are complete garbage.


 * Too Big a size (Size ain't relevant)


 * Stage Boss (Simple as this: Stage Boss Ridley doesn't appear when you play as him in the Pyrosphere)


 * Sakurai doesn't know he exists (64 had Planet Zebes, Melee had the Opening, Brawl had the SSE)


 * Repetetive Playstyle (Sakurai can make any character unique in a certain way, even if it had the same moveset)
