I'd freaking explode if they added a Monster Hunter to Super Smash Bros! The only problem I think there would be is alternate costumes. Normally Nintendo loves to make the alternate costumes homages and/or real costumes that the characters have had before. The most likely costume that a Monster Hunter would don is the Rathalos armor, considering that's what the monster Hunter had in Marvel VS. Capcom, but there are only three different colors of it: Normal (red), Azure (blue), and Silver (grey). there would be a whole swath of colors that seem mandatory for smash bros that would not be normally available unless they wanted to make different armors for each color. If they decide to go with different armors, then you have the problem of making the armors for each color and presumably the male and female versions of each armor. Which ends up being a massive workload. Of course they could always just end up just making up different Rathalos armor colors, but I don't think that the Smash Bros crew really would opt for that. Sorry for the long post, I just love Monster Hunter and Smash Bros, so naturally I would have a lot to say. Also, Adeleine being in Smash would be cool too.
