Firedashing

Firedashing is a nearly useless Fox technique discovered by Hylian that involves using Firefox to bounce off of the stage and edgehog. The technique is present in both Super Smash Bros. Melee and Brawl.

To perform the technique, the player stands on the stage, facing the target ledge. They then jump and use Firefox diagonally into the stage, heading towards the ledge. Upon collision, Fox will bounce off the stage and, if spaced properly, fall right to the edge. If the player holds the control stick/d-pad back (towards the edge) as Fox falls past it, he will grab onto the edge, thus edgehogging.

However, given that the technique requires incredibly precise spacing, anyone who can aim Firefox that well could just as easily use it directly to the ledge, because Fox/Falco's up special moves will grab onto the edge from any direction as long as the control stick/d-pad is tilted towards the ledge when they encounter its sweetspot radius.
