Wind

In the Mario series, wind appears in a few games as an obstacle. While wind can not hurt the player, it can blow them into an enemy or into an abyss.

Super Mario Bros.: The Lost Levels
In Super Mario Bros.: The Lost Levels, wind appears for the first time as the game's new special feature, and are represented by floating leaves. While it is dangerous at times, it is needed to clear some levels. Some gaps are so big that trampolines are needed along with the wind to traverse the gap.

Super Mario 64/Super Mario 64 DS
In some ice levels of Super Mario 64 and its DS remake, like Cool Cool Mountain, Snowman's Land, and Chief Chilly Challenge (DS-only), there are gusts of icy wind that can carry the player over a gap or push them off the edge. The wind also appears in Tiny-Huge Island, Rainbow Ride, and Tall, Tall Mountain. In addition, a cloud enemy called Fwoosh appears in Super Mario 64 DS and guards the entrance to the slide on Tall Tall Mountain and blows wind to attempt to blow the player away. These gusts of wind as well as those of the the Snowman's Land snowman can also blow the character's cap away. One wind gust in Chief Chilly Challenge is so strong that only Metal Wario can get past it.

Super Mario Galaxy
Wind appears in Super Mario Galaxy in the Gusty Garden Galaxy. Here, the player must ride Floaty Fluffs to cross large, windy gaps.

New Super Mario Bros. Wii
Wind reappears in New Super Mario Bros. Wii. Like in Super Mario Bros.: The Lost Levels, it is needed to reach certain parts of the level. It only appears in World 2-4 where it can blow coins around the level, and can be noticed through the sand that it carries along the way. Enemies in the level will turn against the wind when it comes, and don't move until it goes away. It can also push the player right, though Mario can crouch to stand still.

Enemies similar to Fwooshes called Foos blow wind in the form of wispy clouds. This makes it difficult for players to see where they are going, although it doesn't push them back.

Super Mario Galaxy 2
In Super Mario Galaxy 2, wind is blown by windmills in Honeybloom, Cloudy Court and Grandmaster galaxies. The clouds created by Cloud Mario can be carried by the gust, thus reaching far away locations.

Donkey Kong Country 2: Diddy's Kong Quest
In Donkey Kong Country 2: Diddy's Kong Quest, wind is the theme for two courses: Gusty Glade, where it is used to jump over long holes or hinder the player by blowing them into unwanted directions; and Windy Well, where the wind blows upward and lifts the Kongs to high platforms. In this game, the wind is represented by leaves.

Super Smash Bros.
In Super Smash Bros., wind appears on the Dream Land stage. Here, a tree named Whispy Woods blows wind at the player in an attempt to blow them off the stage.

Super Smash Bros. Melee
In Super Smash Bros. Melee, wind appears on the Green Greens stage. Here, Whispy Woods blows wind either left or right, attempting to blow the player of the stage, similar to how he did in Dream Land in Super Smash Bros.

Super Smash Bros. Brawl
In Super Smash Bros. Brawl, wind appears on some levels in the Subspace Emissary, such as The Wilds, The Swamp, The Battleship Halberd Exterior and The Glacial Peak. It blows like normal wind to the side, but it also blows upward in the swamp. The stage Pokémon Stadium 2 will sometimes blow wind, causing it to take longer to get down. Three Flying-type Pokémon (Drifloon, Hoppip, and Skarmory) appear during this stage. The PictoChat stage also features drawn wind. Since Green Greens returns from Super Smash Bros. Melee, so does the wind on the stage. The Borboras, enemies in the Subspace Emissary, also blow wind. The boss Ridley can produce wind during the boss fight.

Mario & Luigi: Partners in Time
Wind makes a very small appearance in Mario & Luigi: Partners in Time. Here, a Fwoosh blows wind to blow the smoke away that comes from Thwomp Volcano.

Yoshi's Island DS
In Yoshi's Island DS, Baby Peach can use her parasol to catch wind currents that allow she and Yoshi to reach higher platforms.

Super Paper Mario
Wind exists near the end of Chapter 3-3 of Super Paper Mario. The player can ride the red wind to the Warp Pipe at the end to finish the chapter.

Mario Kart 7
Wind appears in Mario Kart 7 on several courses, such as Mario Circuit and Rock Rock Mountain. It is often blown out of pipes and can push the player around. However, it can also be used for the elevation of a glider. The Screaming Pillars in DK Jungle blow wind that pushes the player back.
