Anything relating to any “Big Three”, “Big Four”, “Last Brawl Request” of speculation has always been imbued with a special sort of revisionism, mostly used to prop up a character as a necessity to appeal to completionists. Geno fans have definitely made use of the early deconfirmation of most Brawl big hitters to propagate their position as last man standing. Personally, I only remember the Elite 4 of Smash 4 featuring Mega Man, Ridley, K. Rool, Palutena and later Little Mac if I recall correctly, with Mewtwo as champ. Others dipped in-and-out and I can’t doubt the popularity of certain characters but yeah anything related to the argument “Last X of Y not in Smash” is no doubt taking a few shortcuts here and there, and might rewrite history when it comes to cutting that down to a specific “Big insert rhetorically viable number”
As mentioned before, Pokémon base game Ultimate speculation is a bit of a no-mans-land too. For example, some Lycanroc supporters see the ordeal as some reverse-Dolchstoß-myth where their underdog was always doomed to be overshadowed, when in my opinion they would’ve very much been the top dog of Pokémon speculation if it wasn’t for Verge taking the wind out of his sails. Though, I feel that whole ordeal was very much a constant twist so I can’t blame anyone for believing they were the underdog in the situation when they very well might’ve been for a considerable amount of time.
I feel a Dynasty Warriors definitely has the potential for one of those “control schemes native to their series, new to Smash” sets where the Specials change depending on the amount of regular inputs made before it.
