Glide

Glide was originally 's up special move in Super Smash Flash 2 before v0.8a of the demo, where it was replaced by Finishing Leap.

Overview
When performed, Sora would leap into the air while swinging his keyblade upwards, dealing 11% damage to any opponents he hits on the way up. After the leap, he would then start gliding infinitely. The gliding could then be cancelled by angling it far enough upwards, but this would also make Sora helpless in the process. To prevent this, the player must instead cancel it by air dodging, or with a glide attack.

Origin
Glide has been a recurring movement ability throughout the  games ever since the first game in the series, where Sora learns it after sealing the Keyhole in Neverland. The skill allows the user to ride the wind and travel over distances in the air. It can be used as a faster mode of transportation than running, or as an evasion technique. In KINGDOM HEARTS II, it can be leveled up to decrease the angle of the glide, allowing Sora to stay aloft longer, or even permanently. When using Glide in this game, Sora can transition between it and other aerial actions.
