I see. Well, I guess I could use this time to point out something I noticed recently about both Bandai Namco and SNK's representation in Smash. So in Smash Ultimate, both companies are currently represented by a single fighter, unlike Sega, Square Enix, Capcom and Konami, who each have 3, and Microsoft, who has 2. However, unlike those companies' fighters, Pac-Man and Terry appear to be representing more than just their respective series, but more-or-less, their respective companies' entire game libraries (or retro library in Namco's case). And maybe that's because Namco and SNK only have one character in comparison to those other 5 companies.
Terry came with the King of Fighters Stadium stage, tons of Fatal Fury/King of Fighters music tracks, and several spirits and stage cameos of characters from those games. But he also came with several songs and a few spirits from other SNK games like Samurai Shodown, Metal Slug, Art of Fighting, Psycho Soldier, Athena, Ikari Warriors and Alpha Mission. Not to mention Mii costumes for Ryo, Iori and Nakoruru. It's highly possible that we're not going to get another SNK character because of all this, so it was at least nice for Terry to represent pretty much all of SNK with his inclusion.
Pac-Man came with the Pac-Land stage, and a few PAC-MAN music tracks and spirits, but he also came with a lot of other content from many retro Namco franchises, such as music tracks, items, and even taunt cameos from games like Galaga, Tower of Druaga, Mappy, Dig-Dug, Sky Kid, Rally-X, Retro-Cross, Libble Rabble, Legend of Valkyrie, Dragon Buster, Taiko no Tatsujin, and even a couple modern character cameos in the Namco Roulette taunt like Heihaichi Mishima from Tekken, and the Prince from Katamari. So, Pac-Man, like Terry, pretty much represents the entire retro history of Namco, even if it's not to the same level as Terry's SNK representation.
So thinking on this, I thought that if Ryu happens, what are the chances that he represents Koei Tecmo in a similar way that Pac-Man and Terry do for retro Namco and SNK respectively? He could come with a good number of Ninja Gaiden content, such as a Sky City Tokyo stage, and music tracks, spirits, and stage cameos from both the classic and modern Ninja Gaiden games, as well as content from series' like Dead or Alive, Fatal Frame, Nioh, and maybe even Dynasty Warriors and Samurai Warriors. I think that could be a great way to represent not only Ryu Hayabusa and Ninja Gaiden, but all of Koei Tecmo as well.
