The Mid-Air Dash, also referred to as the Fireball Spin Dash (火の玉ダッシュ,Hinotama Dasshu?, lit. "Fireball Dash"), is a move used by Sonic the Hedgehog that first appeared in Sonic the Hedgehog 3. It is a special move that turns the user into a fiery projectile.
The Mid-Air Dash is basically an enhanced version of the usual Spin Dash that can only be used whenever the Flame Shield is wielded. When performing it, the user curls into a ball and spears forward through midair at high speed like a comet of flames, thanks to the Flame Shield.
In gameplay, the Mid-Air Dash is useful for dashing through midair, destroying breakable objects, damaging enemies and gaining a small speed boost, while wielding the effects of the Flame Shield. However, ramming into a non-fire obstacle will cancel the Mid-Air Dash (and cost the Flame Shield).
Sonic the Hedgehog 3
In Sonic the Hedgehog 3, followed by its add-on continuation Sonic & Knuckles and the locked-on version Sonic the Hedgehog 3 & Knuckles, the Mid-Air Dash made its first appearance. In these games, it is referred to as the Fireball Spin Dash (火の玉ダッシュ,Hinotama Dasshu?, lit. "Fireball Dash"). To use it in gameplay, the player must press , or during a Spin Jump. However, it can only destroy one target at a time.
By comparison, this move is useful against Doctor Robotnik’s Flame Craft bosses, since most of their attacks are fire-based and they tend to float around in midair.
In the console/PC version of Sonic Generations, this move is referred to as the Mid-Air Dash. In this game, the Mid-Air Dash look more like the Spin Attack, but with the Flame Shield surrounding it, and it can destroy several targets at once. It also creates a distortion similar to that of the Air Boost when used.
