Tornado

Tornadoes are obstacles that are found in various Mario games.

Super Mario Bros. 3
Tornadoes debut in Super Mario Bros. 3, only appearing in of Desert Land, where they can trap Mario in an air pocket and throw him backwards if he gets too close. The only way to get past one is to run until the Power Meter is fully charged, and then jump into the air before colliding with the Tornado. There is no way for Mario to defeat a Tornado in this game, and thus they will always remain in the same location.

Super Mario 64 / Super Mario 64 DS
In Super Mario 64 and in Super Mario 64 DS, if Mario comes into contact with a Tornado, he is thrown upwards and slowly floats downwards (similar to jumping off a Spindrift). They are also situated next to quicksand, so the player must be careful not to fall in. In these games, they only appear in Shifting Sand Land.

Super Mario Sunshine
In Super Mario Sunshine, Tornadoes are found in the mission Petey Piranha Strikes Back. If Mario gets too close to Petey Piranha, he creates Tornadoes that blow Mario backwards.

New Super Mario Bros.
In New Super Mario Bros., Tornadoes appear in World 6-A. They are very large and immobile. If Mario comes in contact with one, he is thrown upwards and spins as he floats back down (similar to Super Mario 64).

Super Mario Galaxy / Super Mario Galaxy 2
In Super Mario Galaxy and Super Mario Galaxy 2, a variation of a Tornado known as a Galactic Tornado appears. When Mario enters one, if the player shakes the Wii Remote, he will soar high up in the air, then slowly descend, all the while with his arms spinning in a similar fashion to a Tornado.

The Adventures of Super Mario Bros. 3
In The Adventures of Super Mario Bros. 3, a Tornado appears in the episode Mind Your Mummy Mommy, Mario, where a Steam Cloud Balloon is caught in one.

Mario Kart: Double Dash!!
A tornado appears in the racetrack Dry Dry Desert in Mario Kart: Double Dash!!, where it flings racers that drive into it into the air.

Donkey Kong Country: Tropical Freeze
Tornadoes appear in Donkey Kong Country: Tropical Freeze, where they appear in the level Frantic Fields. When one of the Kongs enters a tornado, they are hauled backwards or forwards, depending on the direction the obstacle faces. Rambi cannot destroy tornadoes.

Mario + Rabbids Kingdom Battle
Tornadoes reappear as obstacles in certain stages in Mario + Rabbids Kingdom Battle. During the turn transition between the heroes and the enemies, the Tornado will start moving in a straight line from a random position, deducting some HP from any characters in its path.

Other appearances
Several tornadoes appear in the background of Battle for Storm Hill in Donkey Kong Jungle Beat; however, they have no effect on gameplay.
