You're not going to change my opinion on this as a heads up.He's hard-owned by Disney, so your example is just plain awful. I don't really care about what random person tries to make a bad argument that he's a SE character. They don't get to license him out at any point. The most involvement SE has deals with moveset, and as the creators of the game, who else would Sakurai turn to anyway? That's just common sense. If Sakurai needs help, he always goes to the company who actually develops the games. It's always been the case, and always will. Doesn't make him a SE character in that way.
No matter what, Disney will be involved. And since he's a game character in reality, it makes it hard to take an example of a company who has plausible game characters.
Either way, the core point is that speculation isn't an issue whatsoever. Things like requests were crazy for a long time now. People request characters who effectively have no chance, so to be honest, I don't see how it matters one bit if they originated from a game or non-game to begin with. The chances never "changed" in that regard.
So something that wasn't even a specific thing from the start? The only thing it was was "just Nintendo all-stars", which got changed as soon as Melee by having those who are definitely not all-stars, and then 3rd parties in Brawl. This didn't even become a legitimate thing till Ultimate, the first time he spoke on what his ideal game design was. Never mind things do change and always did, so this isn't a remotely sound argument. It's a major fallacy of "precedence rules and can never change." You don't need to like it, but you're not presenting a sound argument for why here.
Which isn't a good reason to avoid it either way. Nor why it would be a bad thing. It's unconvincing at this point.
I'm down for pretty much any video game character joining the game, but I am staunchly against 4th party additions of any kind. This is a series about video games and has always been strictly about video games. If I wanted to play a Xenomorph, I'd launch up Mortal Kombat, or if I wanted to play with Goku, DBFZ.
