Reverse aerial rush

A reverse aerial rush, abbreviated as RAR, is a technique that is present in Super Smash Bros. Brawl and Super Smash Bros. for Nintendo 3DS and Wii U, which was included in Super Smash Flash 2. The technique is performed by jumping during the turn around animation while dashing, causing the character to jump backwards while keeping the momentum from the dash.

Performing the technique
A RAR is performed by dashing, pressing the opposite direction while running (after the initial dash) and then jumping during the turning around animation. Either a short hop or full hop can be inputted and the character is free to perform any aerial action afterwards.

How fast a character can perform the technique from a standing position is both dependent on how long their initial dash lasts (less dashing frames the sooner the running animation starts) and the speed of their jump.

The length the character travels through the air is dependent on their running speed and how much momentum they keep during the turn around.

Forward moving back aerials
Performing a back aerial out of a RAR is one of the most common uses of this technique. For some characters, this move is one of the best tools in their moveset, usually being fast with great reach; a RAR allows to use the move as an approach option, space more effectively with it or in some cases land a killing blow more easily.

Some characters that notably benefit from this are, , , , among others.

Retreating aerials
By doing a RAR while moving away from the opponent, characters who have great forward facing aerials (fairs, grab aerials and some neutral aerials) for spacing can perform any of these moves during the jump to retreat while putting out a hitbox in front of them, potentially protecting them from an incoming approach.

is a good example of a character that makes use of this technique, having a forward aerial with a big disjoint that can even outprioritize most projectiles.
