Since we are at the start of a DLC season going basically blind, I decide to write down my predictions. I was wondering what we actually know regarding the new DLC and ended up mixing with some of my ideas, but trying not to step away from the realms of possibility. That said, I think the predictions are *too* safe and even though there's reasoning, all of them happening would be kinda boring.
Geno
Let me get him out of the way first, since I may be a little biased regarding him.
If there's any precedent this game is setting is that the highly requested and doomed impossible characters from past smash are getting in. In Brawl, Snake and Sonic opened the gates but we still set fan rules to justify not having certain characters. Cloud in smash 4 blew everyone's mind and yet, we still said "dead franchises aren't getting in", "Sakurai said this about certain character" (more on that later) and other types of gate keeping. Well, here we are, not only *everyone is here*, but the "too big" Ridley and the impossible Banjo are also in. Geno is the one left. Yes, there are many characters now that are arguably more wanted such as Sora and I truly hope there's a spot for both, but if we're talking smash history and what we got so far, I'd say Geno is very likely.
Now, let's talk Spirits. Sure there are two SMRPG Spirits, one being Geno. Many believe this means we can't get an upgrade and I completely understand and agreed regarding the first fighter pass. But not only we have precedent in Smash 4 with Lucas getting an upgrade from trophy to character, ommiting spirits would be super strange. Think about it, imagine having all the kongs spirits and no Dixie spirit, that would basically be a spoiler. Also, as for logistics, some characters have multiple spirits, such as Link, who has his Fighter Spirit named "Link", but also has the Primary Spirits "Link (The Legend of Zelda)", "Link (A Link Between Worlds)" and "Link (Link's Awakening)". The fix is as easy as adding the name of the game in parenthesis to the existing spirits. That way, classic characters, specially First-party-ish, can get an easy upgrade from Spirits.
I personally think that the Geno spirit battle was very weird with him been represented by Sheik, we had a costume in the past game and Beware the Forest's Mushrooms is pretty iconic to have both left out.
Finally I want to talk about his possible Pack, even though Sakurai and his team are amazing, I don't think a SMRPG stage would be that popular, so I'll throw a little curve ball and say Geno will come with a HD version of Rainbow Road, along with a bunch of missing Mario Music (including Beware the Forest's Mushrooms, of course). As for Mii costumes, Gil and Chocobo could return here, along with a Mallow hat and 2 more (more on Cacomallow later).
Worst case scenario is that he's coming back as an upgraded costume with his track as a bonus. I honestly find it hard to believe we won't see anything related to him. I'd honestly be happy, I don't like how he's currently under represented.
Lloyd/Heihachi
Speaking of missing Mii costumes, those two are also weirdly gone. On the first pass I believed Heihachi was the most likely addition, but Terry kinda took the FGC spot. Namco is doing such a good job not only with Smash, but also Tekken and Soul Calibur, there's no reason to not throw them this bone.
I don't have much more to say on them, just that I think one of them will return as a character and the other as a costume.
Pokémon
Yes, I want to avoid forced patterns, but Byleth kinda showed us that there's is a weird tradition with newcomers. The other series to do that? Pokémon.
The thing is, I don't think it's a given that the new character is going to be from Sword and Shield. We have 2 generations not represented with characters and we may get a Gen 4 remake. So there are basically 2 opportunities to use this slot as marketing (SwSh DLC and Gen 4 remake).
As for whom, even though I said Spirits could be upgraded, Pokémon spirits are pretty weird.
Not all Poké Ball Pokémon have spirits and many background Pokémon are also spiritless (though this is not exclusive to this series).
As for who could it be? Well, the Pokémon company has favorites so it's hard to tell, the ones I think are plausible are Sceptile, Golurk, Rilaboom, Cinderace and Inteleon. But again, they could easily throw a Sirfetch'd or Mr. Rime because Pokémon Company.
The thing I personally think is missing, is the representation of Evolution in a fighter, DLC are great for those gimmicks.
Regarding the Stage, let's hope for the return of Poké Floats instead of a Pokémon Stadium 3.
Maybe Monster Hunter, Maybe Doomguy
We are also missing some Monster Hunter costumes and we don't really have anything Monster Hunter besides Rathalos, so there's plenty of space to fill. We did get all the Megaman costumes back and Byleth has a pretty monster hunter-esque moveset, so I'm not big on this one.
Cacomallow is the only thing we have *really* going for Doomguy and we don't even know if it's real. And yes, I'm ignoring the director, NDA exist. But I'm starting to see things a little different regarding Cacomallow and it's actually the possibility of Cacomallow *deconfirming* him.
Byleth came with a couple of Ubisoft costumes, Cacomallow shows Cacodemon and Mallow together. If they come in the same pack, Doomguy Costume and Cacodemon Hat could be the +2 in Geno's pack, or even the opposite, Geno and Mallow being the +2 in Doomguy pack.
Rex
This is another strange one. I went back to the first Pass announcement to see the exact phrasing because I wasn't sure Sakurai said he didn't make the cut at all or just this pass.
To my surprise,
he said they didn't add Xenoblade Chronicles 2 characters because it was announced after planing had already started. Wtf Byleth? How early did Sakurai play Three Houses??
I don't know about Xenoblade, but I'm sure there are more spirits they could add, including Xenosaga, just like Terry had some SNK spirits on his board.
Crazy one
Ok, this is kinda cheating, but we do need a crazy pick to sell the Pass, someone equivalent to Joker. Even though everyone is high on Crash for whatever reason, I'd say the craziest we can go right now is Sora. Just like I said with Geno, all the rules and impossibilities aren't real in this game. If there's any chance of an amazing crossover happening, this is the time. So yeah, I'm placing Sora here.
And I'd like to end with a downer. Even though I said all those things about Spirits upgrading, I don't really believe in Assist Trophies upgrading. This was always the point of the AT, as stated in Brawl's Dojo website: "Assist Trophies allow you to enjoy even more characters who couldn’t quite make it as playable fighters."
So, yeah, I'm not at all against Waluigi, I'd actually love him as character, but I honestly think the community needs to understand that AT and cameos are a way to have their wanted characters in the game. I'd love Lyn and Bomberman playable, but I'm happy they are in another way.
TL;DR
This is my prediction in no particular order with the caveat that I think it's too boring and only some may happen:
Geno with Rainbow Road Stage;
Either Lloyd or Heihachi;
Pokémon (Sceptile, Golurk, Rilaboom, Cinderace or Inteleon)
Sora
Maybe Monster Hunter, Maybe Doomguy
Maybe Rex
No AT upgrades.
What I really want is to be mostly wrong and surprised (though I really want Geno and would love Doom music).
