I'm still not sold on Impa being the slam dunk she's often framed as. Her main selling point is that she's the next most recurring character after the main trio, but her only truly active roles are one mainline game and a couple of spinoffs (albeit some decently well-promoted ones). Even then, to my knowledge there's other major characters in those games aside from Impa (I believe Fi and Ghirahim in SS and Lana in HW), with only AoC highlighting her as part of a trio with Link and Zelda. She's been gaining more prominence than she has in the past, yes, but the bulk of her older appearances were just that of a minor NPC. She doesn't feel truly "evergreen" in that regard.
I think an important thing to note for the Swamp poll was that the unlimited votes made it more of a measure for general acceptance of a character rather than
absolute popularity. I'd imagine many voters had a mix of characters they were actively hoping for and characters they don't know much about but they sound cool and/or they think a series warrants a new character, so they wouldn't be upset by their inclusion. We saw that with Anna leading FE candidates when general fans voted, but sharply dropped off once the dedicated FE fanbase pitched in. The Zelda subreddit turned down the poll, so we don't know how the core Zelda fanbase would move the needle.
That said, Anna's
just a recurring merchant who occasionally has optional playable appearances, whereas Impa's had a handful of decently major roles, so the comparison isn't one to one. To give credit where it's due, Impa might still have strong popularity among the core Zelda fanbase and not just the general fanbase. Even so, it's worth acknowledging the context and limitations of the poll and potential blind spots left over, even if it
is a pretty strong and comprehensive survey overall.
Perhaps this might be the reason I'm bearish on the future of Sonic representation in Smash. It feels to me the franchise is suffering from the same thing that speculators believe is kneecapping Rayman's chances. Barely anybody in Sakurai's country seems to care it exists
Idk maybe these numbers don't tell the full story and it doesn't doom the odds of Shadow/Eggman/whoever but if the franchise does manage to get a newcomer it would be primarily for Western appeal. I wouldn't be shocked if in the next game another big SEGA franchise gets repped while Sonic doesn't gain much of anything content wise.
To be fair that's also a Hollywood movie that deviates from the games a decent amount. Sonic Frontiers broke the series' records of underperforming in Japan, for what it's worth. Couldn't find the details for Shadow Gens, but Frontiers' performance is definitely notable.

It's also worth noting that as a franchise, Sonic is just
bigger than Rayman as a franchise. He gets regular annual releases, a modestly successful series of movie adaptations, an ongoing comic series, and a bunch of crossovers and tie-ins. Rayman, on the other hand, has fallen to the wayside in the past decade. The most Rayman's gotten in recent years was a DLC campaign for the second Mario + Rabbids... And a surprise appearance in Captain Laserhawk, where he does crack, wields guns, and says the F-word. Much of the trepidation surrounding Rayman in speculation is that aside from his Western-centric nature, he's also just not active nowadays, especially compared to other Ubisoft IPs like Assassin's Creed.
Plus, Sonic was evidently big enough to get into Smash for three games in a row, on top of many Sonic characters being decently popular requests. If Sonic as a series was just passed over next game in terms of content I'd be genuinely kinda shocked.
