The Footstool Jump (踏み台ジャンプ Fumidai Janpu, Springboard Jump) is a technique introduced Super Smash Bros. Brawl. When characters are directly above another character, they can press the jump button to bounce off of the character's head. When used in midair, it also functions as a meteor smash. It does no damage and can be used between two and six times in succession (depending on the character), with each jump resulting in approximately half the rebound. Teammates cannot jump on each other (unless Friendly Fire is set on). Like a normal jump, this jump can be short hopped. Players can also footstool off someone hanging on a ledge, but the character being jumped off will not fall and will not gain as much height. Pit performs this move in a cutscene in the Subspace Emissary.
Characters who are sleeping cannot be Footstool Jumped until they are awake or take damage.
Footstool jumping can be also be used as a edge-guarding technique.
 Possible origins
The Footstool Jump is very similar to the classic Mario series action of Mario jumping on a Goomba. Additionally, the move is very similar to one seen in Kirby Super Star and in Kirby And The Amazing Mirror, where players are able to get a large jump by doing so off of their partner's or another Kirby's head.
The Footstool Jump may have also been inspired by Luigi's introduction in the alternate scene of Super Smash Bros. Melee's Adventure Mode after completing the first part of Stage 1: Mushroom Kingdom with a 2 in the seconds spot (XX:X2:XX). There, he jumps on Mario's head and sends him plummeting to the bottom of Princess Peach's Castle, where the part of Stage 1 is located. Luigi subsequently takes Mario's place in the event.
Captain Falcon and Zero Suit Samus can perform an infinite Footstool combo on R.O.B. Captain Falcon's combo begins with a neutral aerial, then immediately fast falling, and afterwards performing a Footstool Jump on R.O.B. and repeating. When Captain Falcon racks up enough damage, he can use the Knee Smash as a finisher. Zero Suit Samus' combo can be initiated with her down smash, then using the Footstool Jump on R.O.B., then immediately using her down aerial and repeating. Zero Suit Samus can also use her dash attack, forward tilt, the second jab in her jab combo, and/or the Paralyzer to mix it up as those moves have jab lock properties which can lead to finishers such a Plasma Whip.
