Talking about the movie's spoilers in great extent: https://thelibraryofohara.com/2019/08/10/one-piece-stampede-spoiler-talk/
Can't confirm everything for certain since I'm going by memory, but I'm pretty confident about most of it.

@goty:
Can anyone tell me who's the character credited as "???" and who's his voice actor?
Spoilers!
[hide]I could be wrong since I didn't pay attention to the specific credit, but I believe it's referring to Ace since he's not credited anywhere else. This is likely to save the spoiler of his ghost appearing at the end of the movie (pretty sure it's just a vision from Ann though, since she's rescued by the Revos and the effect is the same used for the Bijyo Bijyo)[/hide]

@The:
What about Franky? I've heard that he gets the least focus of the strawhats, and that's the deciding factor on whether I'll see this movie or not.
He does some cool stuff and fights a little at the end, but no one named in particular. That said I feel that applies to some other Straw Hats (Nami and Robin for example and even Chopper barely does anything, can't recall him getting in a single real fight), so I wouldn't say he's necessarily dead last in terms of screentime.
[hide]He gets inside the shogun and fights some pacifistas, that's about as much I remember [/hide]
In terms of relevance I'd say Luffy and Usopp are the highlights. After that I'd say Zoro, Sanji and Brook for getting some fights and the rest kinda behind that.

@Kaiolino:
Is Nami good in a way that doesn’t involve fanservice?
She gets some cool moments, even some interacting with Luffy and Usopp, but nothing particularly insane. With how much focus she had in SW and Gold, it's no surprise she plays a minor role here. If anything, Usopp is the Straw Hat of the movie.
[hide]She does however get to unleash Zeus, so that's pretty cool! [/hide]
