Wind

In the Mario series, wind appears in a few games. It is an obstacle in games. 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. While it is dangerous at times, it is needed to clear some levels. Some gaps are so big that springs 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 will be a big gust of icy wind that will carry the player over a gap. There are also wind gusts that can push them off the edge. The wind also appears in Tiny-Huge Island, Rainbow Ride, and Tall, Tall Mountain. Also, a cloud enemy called Fwoosh guards the entrance to the slide in Tiny-Huge Island and blows wind to attempt to blow Mario (Yoshi, Luigi or Wario in Super Mario 64 DS) away.

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 came from Thwomp Volcano.

Super Mario Galaxy
Wind appeares in Super Mario Galaxy in the Gusty Garden Galaxy. Here, the player must ride Floaty Fluffs to cross these huge gaps full of wind.

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 and it blows coins with it. The wind also stops certain enemies in their tracks. It can also push the player right, and can only be stopped if holding down on the Wii Remote. Also, enemies similar to Fwooshes called Foos blow wind, which makes it hard for players to see where they are going.

Super Smash Bros.
In Super Smash Bros., wind appears on the Dream Land stage. Here, a tree named Whispy Woods blows wind, attempting to blow the player of 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. They are 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, making it take longer to get down. Three Flying-type Pokémon (Drifloon, Hoppip, and Skarmory) appear during this. 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 also produce wind during the boss fight.

Trivia

 * Strangely, in New Super Mario Bros. Wii, when the wind is about to come, the enemies all turn towards the wind.
 * Through hacking methods, it is shown that only certain enemies behave in that matter. Buzzy Beetles are one example of an enemy that not affected by the wind.
