The Ice Climbers consist of the duo of Popo (who wears a blue coat) and Nana (who wears a pink coat). While their relationship has been hinted at before, it was never confirmed.
In WarioWare series
Popo reappeared in WarioWare Gold in the microgame, Ice Climber. The player's objective is to grab onto the condor before time runs out. On the third level difficulty, he has to reach the eggplant before time runs out.
In Super Smash Bros. series
Super Smash Bros. Melee
The Ice Climbers made their debut appearance in the Super Smash Bros. series, after sixteen years of the release of their original game. They are a dual-controlled pair of fighters, making them unique compared to the other fighters. They, as a singular entity, are one of the 14 default characters available from the start.
Super Smash Bros. Brawl
The Ice Climbers yet again consist of the duo Popo and Nana. They still fight as a pair with Nana following along. With Nana, special moves are better than just being Popo. Both Ice Climbers can now hang on a ledge at the same time and their Down Special in the air is no longer an auto-freeze. The Ice Climbers' Final Smash consists of a large iceberg taking up a large portion of the screen. The iceberg can damage, and eventually freezes, enemies who come near it.
Super Smash Bros. 4
The Ice Climbers do not return as playable characters for Super Smash Bros. for Nintendo 3DS and Wii U, although they appear in both versions as a collectible trophy. According to Masahiro Sakurai, the Ice Climbers were fully functional in the Wii U version, but because the 3DS has a lack of hardware power, he was forced to cut the Ice Climbers from both versions so that they share the same roster because Sakurai did not want version-exclusive characters. Additionally, they were deemed as low-priority characters since it was very unlikely that the duo would have a new game in their series.
