Sliding

Sliding (スライディング), also known as slide, is a move from the original Mega Man series that Mega Man can use since Mega Man 3 (however, he is unable to do so in Mega Man 9 and 10). It allows him to evade enemy projectiles, avoid some traps and access narrow passageways. It can also be used to move faster. The slide can be executed by pressing the "Down" and the "Jump" buttons together. The slide can be interrupted by jumping. Mega Man cannot attack while sliding, but the slide itself is an attack in Marvel vs. Capcom, Marvel vs. Capcom 2, Super Smash Bros. for Nintendo 3DS / Wii U (the latter which inflicts 8% damage or 5% depending where it hits), and the secret mode from Mega Man 7. Proto Man has the ability to slide in Mega Man 9 and 10. There is no difference between his slide and Mega Man's.

It is important to note that Charge Man's weapon, the Charge Kick, can only be activated by performing a slide. This is the only Robot Master weapon that is not activated by pressing B. Also, in Mega Man & Bass, Mega Man has to use the controls to slide to use the Tengu Blade in the dashing form.

The Game Boy installments implement sliding starting in Mega Man II.

In other series, the only playable characters that can use slide are Model a in Mega Man ZX Advent and MegaMan.EXE in the games Mega Man Network Transmission and Rockman.EXE WS. Other characters use similar actions such as Dash and Crouch to avoid attacks and pass through narrow passages.

Some bosses, like Shadow Man, Saturn, Mega Man?, and Copy X, are also able to slide, and so are all playable characters from Mega Man's Soccer.
