Oh god please no, stop right there. No buffs, no stats, nothing.I think it would pretty cool. And if they give buffs for the combinations too, that'd be awesome. So long as one doesn't have to look atrocious like in U [chi] to get perks then I am all for it.
Yes, I want this to be in KH3 as well. It'd be dumb if it weren't.
This opens so many possibilities and collabs~
