actually, here's a question I have for you.
If Rean got into Smash, what iteration of him would you choose (CS1, 2, 3, 4), and what would you make his Final Smash?
Personally, I always have a hard time imagining what I'd pick. For iteration, I'd imagine a thing where it's 1-2 Rean, with 4 Class VII uniform alts and 4 CSII outfit alts. I really like CSIII Rean's design, but I think it's best to go for Student!Rean for a Smash appearance.
The way I imagine it, the CSI alts would be Green, White, and Black, to be similar to the uniforms of the commoner and noble classes, with black as an extra 3rd color, and the alts of the CSII outfit being color palette swaps that look similar to the CSII outfits of the other Class VII Members.
As for Final Smash though, I can't decide whether I'd prefer him having Termination Slash - Dawn, or Valimar. Going by modern Smash Bros.' FS designs, it'd probably be a cutscene Final Smash, so it really just comes down to which would be cooler. Problems is, they both fit well, and they're both cool.
Estelle does have a bit more going for her aside from just being the first protag though, mostly due to Trails' status as a continuous series with games that all take place in the same world.
Even though she hasn't been the protagonist since 8 games ago, she still makes somewhat regular appearances in the story, and remains at least
somewhat relevant going forward.
