Back in the days of the first Smash Bros., you had to fight an army of PURPLE Polygon Fighters who attacked the player wave after wave. Even though this is unlikely, could this have been a jab at the Polygon Man? We don't exactly know how the Polygon team was created or even the origins before being replaced with Wireframes.
Now, in regards to the "impossible" concept of Sony and Nintendo combining their games to make an Allstars x Smash. What if they used that single moment in history in a way to tie in a point that the team belonged to Polygon Man, who sent them in as an attempt to invade Nintendo's universe? What if he tried this AGAIN? (So to speak), only in a much greater force?
What do you think?
Cool theory but yeah that's not the case, see before the first Smash Bros. was being made it was going to be a completely different game with a set of characters we've never seen before, it was going to have the same style of gameplay though but Sakurai decided to scrap it and turn it into a crossover between Nintendo franchises, now this ties into the theory that the fighting polygon team were just series of prototypes for Sakurai's original project, you can tell that from a few of the polygon designs like how the Mario one is the same as Luigi and Ness or how the Kirby one isn't even the shape of Kirby.
