Fire Fox is one of Fox's special moves throughout the Super Smash Bros. series, as his up special move. Fox charges the move for a few seconds before launching in the direction held on the control stick, dealing a single hit to opponents while flying forward. In Super Smash Bros., Fox briefly charges before taking off in an explosion. In Super Smash Bros. Melee onward, Fox covers himself in fire while charging, which also deals multiple weaker hits to opponents, as well as when he takes off. Hitting a surface while Fox is moving automatically ends the move.
In Super Smash Bros. for Nintendo 3DS / Wii U Fire Fox has two custom special move variants: Flying Fox and Twisting Fox. Flying Fox sends Fox into the air without charging or dealing any damage, as well as lacking any fire effects. Twisting Fox acts similarly to Wolf's Fire Wolf, sending Fox into the air in a drill-like motion rather than covered in fire and dealing multiple hits on the way up, the final hit dealing more damage and knockback.
