Dash Attack

The Dash Attack, also known as Wario Attack and Body Slam , is Wario's signature attack. It consists of Wario charging at high speed while ramming everything on his path using his powerful shoulders. It first appeared in Wario Land: Super Mario Land 3 and has since then appeared in many games featuring Wario, most prominently in the Wario Land series. Its main purpose is to attack enemies, but it can also be used to hit switches or break open treasure chests and Blocks.

Wario's Woods
When Wario performs a Dash Attack, it makes the ceiling fall on Toad.

Wario Land series
The move is a simple attack in these games; it can be used to attack one enemy at a time or to destroy blocks, it normally allows Wario to move faster than running. In Wario Land 3, it can be upgraded to break harder blocks and attack several enemies at once. In Wario Land 4, the name "Dash Attack" was used to describe a more powerful variant of the move where Wario quickly rushes as his speed greatly increases, then, he is able to run into multiple blocks and enemies without stopping. He is also able to break the more solid, blue blocks. His regular attack is also present, but compared to the "Dash Attack", it is less powerful and Wario bounces back against blocks. To avoid future confusion in later games, the name Dash Attack passed to be the name for Wario's regular attack, with the old "Dash Attack" getting removed, but also giving Wario different alternatives to perform similar moves like the Max Fastosity Dasherators seen in Wario Land: Shake It!.

Wario World
In this game, the Dash Attack makes Wario take off in a burst of speed when the player presses the Button. This is handy for quickly moving around or barreling through enemies. Another move, coupling a Dash with a Wario Punch, can be executed by pressing, holding, and releasing the Button.

WarioWare series
In the WarioWare games, the attack is used in some microgames, for example to enable Wario to break through walls to escape an avalanche of gold and treasure.

Wario: Master of Disguise
The attack returns in Wario: Master of Disguise, but only Thief Wario can use it. Unlike in past platformers featuring the move, Wario does not rush forward while executing it.

Super Smash Bros. Brawl
The attack appears in Super Smash Bros. Brawl as one of Wario's Smash Attacks. Like in Wario: Master of Disguise, he stays in one spot while executing it (unless in his Wario-Man form).

Trivia

 * Sometimes Wario's Dash Attack doesn't make a Thwomp fall; when Wario's timer is about to end and Wario is doing Dash Attack, it will not affect it on the ceiling.
 * Roy Koopa is shown to possess a similar attack in his dummied sprites for Super Princess Peach as well as in New Super Mario Bros. 2.
