Not gonna comment at all on the competitive viability of my roster: I do not have enough in-depth mechanical knowledge of Smash and fighting game character design so honestly it's probably pretty bad lol. The newcomers I have no idea how they'd even play besides some basic big picture move ideas, I couldn't tell you a damn thing about what Shadow's combo options or Raven Beak's kill confirms would look like.Before going in, your roster, your project at the end of the day.
I'll chime in as both a competitive player and someone who has strong opinions on roster construction in a more broad sense.
As a competitive player, i'll admit, this doesn't look great for our world. i'm kinda left looking at this list and i'm wondering like, who can do combos? who are our disjoint characters? this seems like camper hell. (I'm intentionally using 'camper' a bit vague in this more casual context. further elaboration is available.)

Here, Green = broadly recognized as good for the game, Yellow = uncertain, Blue = gimmicky, Purple = notorious camper, Black = new (no knowledge). I did this quickly and probably whiffed some (Mario, Peach, and K. Rool among those one could dispute), but there's a whole lot of blue and purple. (And the character switch Pokemon trainers will also probably also be gimmicky.)
One could say here like, I could redesign these characters, and that Ultimate puts you in a bad spot because so many characters are campy and gimmicky. And I'd say, sure, the former is possible and the latter is broadly true, but this game does not look super fun for non-casuals. Lots of fun, balanced, non-campy characters are out here: Roy, Chrom, Sheik, Captain Falcon, Wolf, Pichu, Mewtwo, Incineroar, Corrin, Pit, and Ridley are cut, and likely more too.
(I probably should've included Ken here as a good character because he's different enough from Ryu, but I'm too lazy to edit the image.)
____________________________________________________________________
For non-competitive, I'm more mixed here. I'm generally a fan of smaller rosters both for competitive reasons (less matchup hell) and casual reasons (eg more effort put into other parts of the game, characters feel more distinct and identity-having, less choice paralysis, easier to learn the whole roster for random). So that's great in my book.
And given that, you made some of choices I agree with, ones that other people often don't. These choices are especially difficult when deciding who to cut and not. You kept good gaming history and casual play in with guys like Isabelle, G/W, Duck Hunt, and Pac-Man. I'm real tired of rosters where all of DH, G/W, Wii Fit Trainer, and Mii Fighter are cut – I understand you may not keep them all, that's cool, but people who cut them all out feel like their design POV is too sterile and missing a lot of what has made Smash unique and great.
Foreman Spike has big gadget Piranha Plant energy that i'm totally down for. New Pokemon content post Gen5 is a nice dose of reality. I think the echos are all solid adds, but I'm surprised no Dr. Mario. While I'm a bit bummed about losing Ridley in an gameplay sense, I think Raven Beak is a totally fair swap in the non-mechanical world, at least, the kind that most people would be too nostalgic or conservative to make but which can definitely help Smash get its own identity.
The only grief I'll give you on removals is Pit. A character so intertwined with the Smash franchise (revived for Brawl, Palutena as the exemplar of 4's Custom Moves, KIU inspired the UI of Smash 4, Palutena's Guidance, etc.) should get one spot, I'm pretty sure, especially when other life support/dead franchises like Star Fox / Mother get one or more.
However, in general I'm not super high on the other additions. Most fan rosters tell you what franchises the maker likes vs dislikes, and like, that's fine – it's natural that personal interest influences this personal interest franchise. However, I think that type of interest is best expressed in thoughtfully allocating spots and making designs and concepts, and there's some spot bias here for Xenoblade, Sonic, and traditional fighting games. These three franchises, none of which are that important to Nintendo, take more than a quarter of the whole roster. (Echoes not included, besides Ken, who is classified as an echo but is functionally a separate fighter.) 13/50. Tmk, Ultimate simultaneously has proportionately more Nintendo characters and shows a broader swathe of nontraditional entrants.
I get the POV on including one Xenoblade character for each game, but cutting the roster and adding to a franchise that just got DLC and isn't that big-picture important feels hard to justify. It's your roster at the end of the day, but if it were me, I'd cut one Xenoblade, make Shadow a true echo, and cut at least 2 of the traditional FG guys.
I don't think gating access to the Pokemon franchise behind a gimmicky swap mechanic is a great idea. No solo Pikachu, while certainly bold, was a bit boggling. If you want Cynthia and her Garchomp, you can make a solo Garchomp character with her as a background trainer, and I might recommend it. Also, I'm not really sure what your opinions on the newer games are, but you gotta include Pokemon content from the past 10 years. Adding solo Mewtwo, a solo newer Pokemon, and splitting Pikachu from Charizard would do a lot for me here.
I really don't like Bandana Dee. I don't. He's very corporate mascot to me, both in appearance and functionality. Maybe he's gotten major upgrades in FL - I don't know a lot about for him – but people have been clamoring for him since RTDL, where he has no story role or agency. I read his situation as a Geno or Waluigi situation, where the hype is self sustaining but questionably founded. He's cute, but in a kind of generic way that Kirby already slots into. I think Kirby has a wealth of diverse side characters that show the franchise's history and creative gameplay more, like... most of the Star Allies dream friends, honestly, and also Dark Matter.
In conclusion, #AdeleineForSmash2026
Funnily enough giving Xenoblade 3 reps wasn't motivated by personal bias at all, I've never played any of the games. I just kinda figured "ok the series is prestigious and acclaimed enough to merit someone besides Shulk and at that point you have 2/3 so might as well go all the way". Now Sonic on the other hand I am guilty as charged, and that bias prohibits me from just making Shadow an echo fighter. Yes, in quite a few games he plays as a Sonic clone, but there's just as many where he shows off his own unique powers from Chaos Spears to teleportation. Shadow Generations was what really tipped the idea of making him an echo into unacceptable territory for me, the Doom Powers simply open too much moveset potential to settle for a Sonic reskin.
Now, I didn't do the math, but if what you say about my roster having proportionally more third parties than Ultimate is true than that's an oopsie on my part I promptly need to recalibrate: One of my goals was to actually substantially scale back third party representation as I do think it got kind of ridiculous in Ultimate's DLC. I at least accomplished the "trimming down the number of franchises to mainly close Nintendo partners and really big boys like PAC-Man and Minecraft" part of that, but still. I reckon I'll move Akuma to DLC, junk Geese and add in Pit and two other Nintendo villains (Note how there are 13 villains with Xehanort included).
Yeah you know the more I think about it the more I realize making every Pokemon rep Pokemon Trainer but with 2 guys was a bad call. It just makes adding in more from that franchise way too cumbersome (e.g. I wanted to add Lillie but realized she has no Pokemon popular/important enough to be Smash characters).
Truthfully Bandana Dee wouldn't be my first choice for a new Kirby character either. I put him in because 1) tapping into my cynical marketer side and adding an obvious fan request and 2) because Kirby doesn't have a ton of regularly recurring characters across games besides the current trio, which is also why I didn't put in a new Zelda rep (e.g. if you added Skull Kid you'd inevitably have people going "What about Tingle/Midna/Urbosa etc." without any real coherent rebuttal). Those kinds of characters are better saved for DLC I reckon (Raven Beak is an exception here but unlike Kirby and Zelda Metroid has a very defined episodic chronology which he was made very important to). I do think Dark Matter and Magolor fit this criteria just enough, and now I could swap one of them in with those 2 freed up villain slots...
