Kick

Kicking is a move closely related to punching that appears in many Mario games. It is either part of a attack combo or a midair attack. Almost every playable character with legs can kick, though Boo uses its tail instead.

Mario Bros.
In Mario Bros., Mario or Luigi must kick enemies after flipping them over in order to defeat them.

Super Mario Bros.
The move was first seen in Super Mario Bros. where either Mario or Luigi were capable of kicking Koopa Shells at their opponents or obstacles. The kicking of Koopa Shells later returns in most future Super Mario games. The later games, such as Super Mario Bros. 3, also introduced the concept of kicking other objects aside from Koopa Shells in order to gain other effects.

Super Mario 64
Mario kicks to end an attack combo in Super Mario 64 and Super Mario 64 DS; he can also do so in midair, to attack enemies and stall his fall (both Luigi and Wario were also capable of performing kicks in the latter game).

Super Mario Galaxy
In Super Mario Galaxy, Mario can kick enemies away after stunning them, similar to Mario Bros. A move called the Double Kick also appears, which gets its name because of how Mario does a kick with both legs while doing the move.

Super Mario Galaxy 2
Mario can kick in Super Mario Galaxy 2, with the move having the same purpose as its predecessor.

Mario Party 2
In Destruction Duet, players may have their characters kick the Bowser Statue by pressing while in mid-air, damaging and eventually destroying the statues.

Super Mario Strikers
In Super Mario Strikers, the game relies on this move a lot as the series is based off of soccer, a kick-centric real world sport. The Super Strike, respectively, is the most powerful kick in the game.

Mario Strikers Charged
Kicking reappears in Mario Strikers Charged, having the same purpose as its predecessor. In this game, the Super Strike was replaced by the Mega Strike, another powerful kick.

Super Smash Bros. series
In the Super Smash Bros. series, almost all the playable characters are capable of using kicks as a form of attack. Midair kicks are also possible for some characters. Some kicks are also special moves, like Captain Falcon's Falcon Kick and Ganondorf's Wizard's Foot.

Wario's Woods
In Wario's Woods, kicking is one of Toad's signature abilities in the game. He can kick aside the various enemies in the game to line them up with each other. With bombs, Toad can kick them if they are set on the ground.

Super Mario Bros. 3
