Notes:

I'm not sure if this better fits in the Crossover or Super Smash Bros. galleries. It could go into Crossover because of the Blaziken (I beleive Potoo's name for her is Juniper) using Ganondorf's Up-Tilt from Super Smash Bros., but it could also go into the Smash Bros. gallery because of said move.
I decided to put this in here because I think the focus is more on the characters than the move, which I think is just a reference to Smash Bros. instead of something remade with different characters or to represent the base game. Of course, the title disproves my reasoning and suggests that this should go into either Crossover or Super Smash Bros., but the actual ties in the image are still a little weak and this totally isn't me losing motivation to think about this any harder.
Also I'm not sure what the Dewott's name is, I think it's Mira based on this post's tags.
