Ice Climbers

The Ice Climbers are a little boy named Popo and a little girl named Nana, who climb ice mountains. Despite being very young, they are the best climber's around. Popo was seen in WarioWare: Twisted!, in one of the Mini-Games. One of these two my be the playable character in the Game and Watch game Climber in Game & Watch Gallery 4. The Ice Climbers are very rarely linked to the Marioverse, but the most recognizable appearance was Super Smash Bros. Melee.

Super Smash Bros. Melee
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 seperate 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.

It is currently unknown if they will return in Super Smash Bros. Brawl. It is very likely, as many have grown to like the team system, even wanting Baby Mario and Baby Luigi or Toad and Toadette to be a team.

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.''

Trivia
