Ice Climbers

The Ice Climbers are a pair consisting of a little boy named Popo and a little girl named Nana, who wear a blue Inuit parka and a pink Inuit parka respectively. They debuted in the VS. System game VS. Ice Climber, which released in 1984 before being ported to the Nintendo Entertainment System as Ice Climber. The Ice Climbers have not starred in any other game, although they have made several guest appearances within Nintendo-related crossovers, and they are playable in a few of the Super Smash Bros. games.

Nana was originally depicted with having blonde hair on Ice Climber's Japanese and European box covers. In the Super Smash Bros. games, both she and Popo have brown hair.

Ice Climber
In Ice Climber, Popo and Nana compete in climbing to the top of one of 32 different mountains. Along the way, they have to break blocks with their hammers to open up paths and ride on clouds on their way to the top. They encounter several animals along the way, including Topis, Nitpickers, and Polar Bears. At the top of the mountains the fastest Ice Climber got the chance to collect vegetables. If either Ice Climber has reached the peak, they could grab a Condor.

Super Smash Bros. series
Popo and Nana are playable characters in three Super Smash Bros. games: Super Smash Bros. Melee, Super Smash Bros. Brawl and Super Smash Bros. Ultimate. The Ice Climbers are notably absent from Super Smash Bros. for Nintendo 3DS / Wii U, but they make a cameo as a collectible trophy. In a column for Famitsu, Masahiro Sakurai claimed that the Nintendo 3DS's technical limitations prevented the Ice Climbers from being included. Sakurai wanted to keep the roster identical for both games, so the Ice Climbers did not appear in Super Smash Bros. for Wii U either.

WarioWare series
Popo makes a number of appearances in the WarioWare series of microgames based on Ice Climber.

In WarioWare, Inc.: Mega Microgame$! and WarioWare, Inc.: Mega Party Game$, the player controls Popo in the Ice Climber microgame, in which Popo has to grab the condor's feet. This microgame would later return in WarioWare Gold.

In WarioWare: Twisted!, the Ice Climber microgame involves Popo having to smash enemies with his hammer.

In WarioWare: Touched!, Popo appears as the sprite in the third difficulty level of 8-Bit Hero.

In WarioWare D.I.Y., the Ice Climbers microgame involves the player having to make Popo jump to grab the eggplant from a Nitpicker

In WarioWare: Get It Together!, he makes a cameo in the Ice Climber microgame, where he is seen hanging onto the condor.

Super Mario Maker
The Ice Climbers appear as one of the add-on Mystery Mushroom costumes that are unlocked after completing an Event Course titled "Popo & Nana's Climbing Challenge" in Super Mario Maker. Their animations and sound effects are taken directly from their original game.

Trivia

 * In the German version, Popo was renamed to "Pepe" due to "Popo" meaning "buttocks" in German.
 * The Ice Climbers' Chinese name literally translates to "Snowman Brothers," despite Nana being a female.
 * The Ice Climbers' losing/"No Contest" animation shows Popo and Nana crying rather than clapping, a reference to their "No Bonus" animation from Ice Climber.
