So we already talked about how it seems Daisy is bouncing her hip against someone else, and that very well could be shantae.
But who else looks like they could be interacting with others? We know not all of them have to be. Like Dark Samus and K Rool don't seem like they are. But we know new fighters could though, as with Chrome and Robin and possibly Ridley and Toon Link.
So I looked and found a few other possible characters that could be interacting with other new comers.
Villager here looks like it is by himself just trying to catch a butterfly, but I could easily see someone else her could be chasing, or cheering him on. Isabelle comes to mind here.
I mentioned Toon Link with Ridley, but on the non wrap around picture thise wouldn'y work. So its possible he is aiming at someone else
Right now it looks like Mewtwo is fighting Lucas, but he is not looking towards Mewtwo at all. I feel like this will get moved later for each of them to be fighting someone different.
He's commanding his Pikman(carrying Mr Saturn for some reason...), but it feels like something is missing here. Why is this the only Item here? That Mr Saturn is very odd and I think is either tied to someone like Ninten chaising it, or possibly a place hold for Carrying someone new.
Snake seems to be taking aim at someone, but I cannot find who it could be.
Last this is more something that proves we are getting more. Mii gunner is not with the other 2 Mii's, which seems very odd. They should be together.
