Since we're posting a couple rosters, I might as well drop mine
My previous rosters were here, for reference:
But I wasn't that satisfied with it. Firstly, I had to cut a crapload of third-parties, since I was juggling veterans, Switch-era newcomers, and hotly requested newcomers. Second, because I wanted at least
some third-party presence, I resorted to cheating and upped the roster count to 64. A 60-fighter roster was already pushing the suspension of disbelief for a game, and I really didn't want to go above that. And third, I just don't like how I arranged the roster, due to the awkward number I got when factoring in Echo Fighters.
So I started over again; Since I was preserving more veterans, I operated on the idea that series would only get three fighters initially (Not counting Echoes, who aren't counted as a full fighter); Some series were slated to get even less than that anyways, so I had some free spaces to work with. This also had the effect of massively downsizing the Mario, Pokemon, and Fire Emblem casts - The largest in Ultimate's roster - to only four unique fighters each, as well as trimming down the different iterations of Link and Zelda. I was also intending to primarily focus on first-parties, with third-parties being treated more as guest characters, at least for the base game. Even so, I had settled on a set of eight third-parties I was dead-set on keeping.
This led to a couple sacrifices that I wanted to keep around - Namely, Andy and Ayumi. Their games weren't blockbusters, but they represent the revival of old dormant IPs, and I wanted to represent that. Unfortunately, there just wasn't enough space, and those two weren't of the highest priority. I also genuinely forgot to add the Mii as a separate character, so let's pretend there's a more in-depth character creator off-screen that incorporates the Miis as a customization option.
Also the roster maker I was using was finicky as hell so I needed exactly ten Echo Fighters or else it wouldn't make a perfect rectangle. Specifically I worked in Blood Falcon and Sylux to hit that quota. They're literal roster filler. Point and laugh at them.
Honestly I'm pretty proud of how this turned out. I think I managed to find a good balance of veterans, Switch-era characters, longstanding requests, and third-parties; I also want to say I kept this roster
somewhat realistic, while still having a couple fun but less likely choices to let it stand out. I'd write up a larger rundown of my choices, cuts, and reasoning, but I want to hear what everyone thinks of this. So, I'll post this here and respond to any questions as they come.
(Also since it might not be obvious: Zelda's supposed to draw from Echoes of Wisdom, but there wasn't a non-chibi image of Echoes Zelda that wouldn't stick out from the other Zelda characters; Pearl is present in Marina's moveset as an assist character; And Echo Fighters are given a bit more freedom in working in more unique attacks and specials, but are still at most semiclones)
