That's great! She seriously does have an incredible amount of moveset potential for smash which is why I believe she is much more likely than Heihachi or Lloyd.
Anyway, I found a new leak with KOS-MOS in it but it also has Yuri and some retro reps you'd think would be perfect for smash. I dont think it is real one bit as we know that it's a red flag for any leak to know the final roster but I felt the need to share it because it seems plausible besides the 2 namco reps part. Yuri Lowell would make sense since Vesperia hd remaster did get a switch port. Yuri is also one of the most popular tales characters in Japan so it's not too crazy to expect he can make it.
That being said, here's the newcomers in the leak.

Yuri
KOS-MOS
Mach Rider
What do you think? KOS-MOS and Elma have both appeared in leaks before including the video I shared awhile back. Yuri is popular in Japan and has a switch port of his game, Mach rider is that wtf retro rep nobody would expect, etc. It seems kind of like a wish list roster but at the same time it has very likely fighters.
Why this leak might not be real: Two namco reps... would put us at 3, and there's too many newcomers. We know Sakurai said "few" are left but it's just speculation at this point. Few can mean 7 or it can mean 3. It's very vague.
KOS-MOS's popularity for ultimate sure is higher now as she's appearing in quite a few leaks. Whether these leaks are even real or just fake still proves she's part of the conversation now. I do see her getting in one day even if it seems like wishful thinking.
