Dash Attack

The Dash Attack, also known as Shoulder Bash, Body Slam , Barge , Wario Attack , Dashing , or simply Attack  , 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 Land series
This move is a simple attack in these games; it can be used to attack one enemy at a time or to destroy blocks, and normally allows Wario to move faster than running. Jumping in the middle of this attack changes it into a Jump Attack, which ends upon landing or turning around. The cave master from Wario Land II makes use of a similar attack when he is confronted by Wario in order to knock him out of the arena, forcing Wario to restart the battle; in turn, Wario must attack the cave master the same way three times to claim victory. In Wario Land 3, it can be upgraded to break harder blocks and attack several enemies at once. Wario Land 4 was the first game to introduced the name Dash Attack (and subsequently its aerial variant Jumping Dash Attack), however, unlike its contemporary usage, this term was used to describe a more powerful variant of the same ability 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 this "Dash Attack", it is less powerful and Wario bounces back against blocks. To avoid future confusion in later games, the name Dash Attack was given to Wario's regular attack, with the original "Dash Attack" move getting removed, but also giving Wario different alternatives to perform similar moves like the Max Fastosity Dasherators seen in Wario Land: Shake It!.

Wario's Woods
When Toad takes time in a round, Wario will temporarily take the place of Birdo and perform an attack periodically, knocking the ceiling a step downwards.

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 Attack with a punch, can be executed by pressing, holding, and releasing the Button.

WarioWare series
In the WarioWare games, due to Wario's focus on microgames creation rather treasure hunting, the Dash Attack is rarely seen or used by him. The attack appears in a few microgames referencing the Wario Land games, for example, in Loot Scoot, it enables Wario to break through walls and repel mummies to escape an avalanche of gold and treasure; another example is found in a microgame simply titled Wario Land (specifically based on Wario Land 4) where Wario must use the Dash Attack to successfully take out a Spear Mask while avoiding its front spear.

Wario: Master of Disguise
In Wario: Master of Disguise, Thief Wario can use a short-ranged Dash Attack. Unlike in past platformers featuring the move, Wario does not dash forward while executing it, instead immediately returning in place.

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

Super Smash Bros. Ultimate
The attack makes a return in Super Smash Bros. Ultimate, this time as Wario's dash attack. It behaves closer to the Dash Attack from the original Wario Land games, covering a longer distance.

Trivia

 * 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.
 * In Yoshi's Island DS, Baby DK has this move, rather than Baby Wario.
