Double Jump (airborne)
The Double Jump (also called Midair Jump in Super Smash Bros. series) is a move used in Super Mario 64, Super Mario 64 DS, Super Mario Sunshine, the Super Smash Bros. series and New Super Mario Bros.. The player must simply Jump twice in a row to use it (jumping three times in a row executes a Triple Jump). It can be used to reach high places. It is the same as a Jump, but a bit higher. All four characters can use it in Super Mario 64 DS, and most of the characters in Super Smash Bros. and its sequels Super Smash Bros. Melee, Super Smash Bros. Brawl, and Super Smash Bros. for Nintendo 3DS / Wii U can. It can also be used in New Super Mario Bros. Wii, Super Mario Galaxy, Super Mario Galaxy 2, New Super Mario Bros. 2, and New Super Mario Bros. U.
It is noticeably one of the few jumps the player can use while standing still. However, in New Super Mario Bros. and New Super Mario Bros. Wii, Mario (or whoever's being controlled) must be running at full speed.
In Super Smash Bros. series, It can be performed by all characters in all four games (Super Smash Bros., Super Smash Bros. Melee, Super Smash Bros. Brawl, and Super Smash Bros. for Nintendo 3DS / Wii U). This move can be performed by pressing the Jump button or tilting the 
upward when a character is in midair, which will make a character to boost upward. This move can serve many helpful purposes in a match, such as reaching high platforms and recovering from being knocked off of the stage. Some characters' midair jumps can go higher than other characters', and certain characters, such as Kirby, Jigglypuff, King Dedede, and winged characters can even perform multiple midair jumps without touching the ground.
Certain items can change the effect of a midair jump. For example, a Bunny Hood will augment the height gained from both a normal jump and a midair jump, and the Screw Attack item, when equipped, turns any character's midair jump into a spinning attack that deals damage to the opponent. When a character is carrying or using a heavy item, such as a Hammer or a Crate, they will be unable to perform a midair jump.
