Ice Climbers are character candidates for SSB4. The most likely change is that they won't seperate and they may have a blend moveset (a set of moves that are from any previous smash games blended together) along with a new final smash. They were in Melee and Brawl so it's not likely they will go anytime soon.
Final Smash: Mountain Breeze
Popo and Nana spin their hammers to create a freezing cold gust that blows opponent's off the stage. Which is really cool. Here's what I think the people should do: Once you go to the character select and select the Ice Climbers, you should decide if you want them separated or not. That is a fair thing.
