I'll say this, if we're still going about how the Japanese view who they want and what they want from that fanpoll. IMO, when you get down to it, fanpolls are really only just "gauging" what the whole flavor of which countries or circles want and don't mean much,
with the exception of certain characters.
For exmaple, Rex & Pyra being Japan's most wanted Smash DLC characters isn't all that surprising, to be quite honest, since most likely because they're essentially the new King K. Rool now over there, from what I've been seeing. K. Rool was their most wanted for a long time, no doubt a good handful of us saw, and now that the request finally has been made, with the timing with Xenoblade 2's release and how much of a splash it made over there, it only made sense for them to make those two their "next K. Rool" after the confirmation back in August. The thing is, however, Japan
doesn't often make pushes for any certain character, so if they're set on one character, they'll be set, which is why I'm not honestly surprised those two are still wanted over there. Hell, if anything, the Mii Costume reveal only pushed the want further.
I ain't trying to say this as someone who still wants the duo, but as someone who's been semi-closely gauging since this exact same thing happened with King K. Rool, when he got the Mii Costume treatment and still continuing to push on. And even if we're going down that list, I don't think Sans being wanted by the Japanese is surprising either. Undertale are massively revered by those guys, just like how various other Western IPs are, such as The Last of Us, Spider-Man, what have you. The fact it has elements inspired by Touhou Project --
which reminder, still the biggest indie franchise -- and colorful characters with a touch of EarthBound? No doubt they'll eat it up. Japan loves a lot of Western media more than you think.
I think the one thing, if anything, is we need to realize this:
as we get more and more characters off the checklist, more and more will Japan's wants for the next Smash DLC characters align with ours. And this goes with all countries, if I'm being honest. Their wants nowadays isn't really far off of what who WE want for characters, because it's starting to get more and more difficult to pinpoint an exact want, hence why you see characters like Banjo & Kazooie, NieR Automata's 2B, Crash Bandicoot, Sans and Sora, etc -- characters who America ALSO wants, hell, maybe even Europe, or even other countries too. It's become a small world.
At this point, if the rumors are true,
Erdrick will be the last true "Japan-leaning" character. After then? All bets are off.
Anyways, those are my two cents about Japan and Smash. Thank you for coming to my 50th TedTalk.
