That said, it's a bit odd how this isn't the 'final' roster, even if it is real. There's still space for two more characters, and even with the Mii fighters in, there's one slot left open…

So I i try to fully look into leaks that look like they have some merit so i did some searching

so this is either fake or very lazily done on Nintendo's part cause the three characters here use the
same renders and poses from their trophies
