Neutral special move
The neutral special move (officially referred to as standard special move prior to Ultimate, also known as neutral B, standard B, B move or simply B) is a special attack performed by pressing the special move button without holding a direction on the control stick. As the original Super Smash Bros. lacks side special moves, neutral specials can also be used if the stick is tilted sideways; with the introduction of side specials in Melee, some characters' neutral specials were changed to be side specials, with a new neutral special taking their place.
The majority of neutral specials are either a projectile or a strong single-hit attack that may be chargeable (and sometimes both). If a character has a single projectile, it is most likely to be their neutral special. Neutral specials also tend to not move the character.
Reverse neutral special move
Main article: Reverse neutral special move
A reverse neutral special move allows a character in midair to use a neutral special in the opposite direction that they're facing. This requires a different method than simply holding backward and pressing the special button, as this would activate the side special move. Instead, one must tap the control stick in that direction and allow it to return to its neutral position before pressing the special button.
In Melee, Brawl, and Smash 4, the player can perform a reverse neutral special move by tapping the control stick in the opposite direction they are facing right after they press the special button. This can be done on the ground and in the air, although some characters will not reverse even when doing the input or have extreme difficulty doing so, such as Samus.
