Ice Climbers

The Ice Climbers are a pair consisting of a little boy named Popo and a little girl named Nana, who climb ice mountains. They are from the game Ice Climber, which was also mentioned in Game & Watch Gallery 3. One of these two may also be the playable character in the Game and Watch game Climber in Game & Watch Gallery 4. Despite being very young, they are two the best climbers around. Popo was seen in WarioWare: Twisted!, in one of the Mini-Games. The Ice Climbers are very rarely linked to the Marioverse, but the most recognizable appearance was Super Smash Bros. Melee. They also appear in the crossover game Tetris DS.

Super Smash Bros. Series
The Ice Climbers appeared in Super Smash Bros. Melee, as one of the new characters. On top of being new, they were also default. The two are unique, as they fight as a team, but ironically act as two separate characters. Thus, they act as a literal 2-in-1 player. They can be very hard to avoid, as they are a team, but once one is gone, the other is a cake walk. In the same sense, if Popo is defeated, then the two will lose a life even without Nana being defeated. Their attacks are not incredibly powerful, but they can use two attacks at once, as well as use two items at once, and hold and throw two people at once. Overall, they can be very difficult for beginners to use, but powerful, and tricky if used right. Both Popo and Nana are voiced by Sanae Kobayashi.

The Ice Climbers will be returning in Super Smash Bros. Brawl, with an updated appearance. Their appearance now adds detailed fur to their Parkas. Their Hammers also have a more detailed appearance, actually showing the wood rings. Their only confirmed attack so far, is Blizzard. The Ice Climber stage in Super Smash Bros. Brawl is The Summit, which matches the Ice Climber style completely. Interestingly, a fish not seen in Ice Climber can be found on this stage. Their battle entrance features them holding on to a Condor, with them jumping off to land on the stage.

Classic
''That's Popo in the blue and Nana in the pink. These two stars of the game Ice Climber have scaled many an icy summit in their mountaineering careers. Back in their glory days, they chased eggplants, cucumbers, and other vegetables that inexplicably fell from frosty summits when a condor reigned supreme. They're rarely seen apart.''

Adventure
''This unique twosome fights together as a team. Your score will not be affected if the CPU-controlled character is KO's, but a lone Ice Climber won't be able to use teamwork moves, which will make for a tough and frantic solo fight. The Ice Shot fires mini-glaciers out of their hammers, while Squall Hammer is at its strongest when Nana and Popo combine their strength.''

All-Star
''The colors of the Ice Climbers' parkas denotes who's in the lead: Nana's in pink or orange, while Popo's in green or blue. Their hairstyles are also slightly different. Belay allows them to cover great distances, but doesn't give foes the chance to target their landing. Blizzard is best used in close quarters; in the fray, Nana and Popo will sometimes freeze opponents.''
