Bounce Attack

The Bounce Attack (バウンドアタック), also known as the Bound Jump, Bound Attack or simply Bound (バウンド) is a move used only by Sonic the Hedgehog. It first appeared in Sonic 3 & Knuckles, and later in Sonic Adventure 2, Sonic the Hedgehog (2006) and Sonic Generations (Classic Sonic only). It has also appeared in Sonic Advance 2 and Sonic Advance 3. The Bounce Attack allows Sonic to perform a downward attack.

Description
While in a mid-jump or in the air, Sonic curls into his spinball form and spin attacks directly downward. Once Sonic hits the ground, he will bounce back up into the air, and can then perform the downward attack again. With each bounce, Sonic will go higher in the air until he reaches a certain altitude.

Sonic 3 & Knuckles
The Bounce Attack first appeared in Sonic 3 & Knuckles. In order for Sonic to use the Bounce Attack he has to have the Water Shield equipped. To perform the Bounce Jump, the player has to press the A- B- or C-button right after doing a Spin Jump. When bouncing back into the air from the Bounce Jump, the player can do the Bounce Jump again by pressing the A- B- or C-button again. If the attack is done on top of a badnik, the player can achieve a vast jumping increase, especially if this is done underwater.

Sonic Adventure 2
In Sonic Adventure 2, Sonic has to possess the Bounce Bracelet to perform this move. To perform this move, the player must press the jump button, followed by the action button (B button in the Dreamcast and Gamecube versions of Sonic Adventure 2). The attack can be done perpetually.

Sonic Advance 2
The Bounce Attack first appeared on the handheld in Sonic Advance 2 and is performed by pressing the B button. When using it in this game, Sonic literally stops mid-flight when using the Bounce Attack, and leaves after images when used. This can be used to open pathways under Sonic.

Sonic Advance 3
The Bounce Attack returned in Sonic Advance 3 and is performed by pressing down and the B button. Sonic can only perform this move when he has Knuckles the Echidna as his partner however.

Sonic the Hedgehog (2006)
In Sonic the Hedgehog (2006), this move can be used to deal extra damage to enemies (although, unlike in Sonic Adventure 2, the bounce attack in this game makes Sonic lose all forward momentum). Just in Sonic Adventure 2, Sonic has to possess the Bounce Bracelet before he can use the Bounce Attack. In order to perform it, the player to press the square button and X button in in the PS3 and Xbox 360 versions of Sonic the Hedgehog (2006) respectively.

Sonic Generations
The Bounce Attack also appeared in Sonic Generations due to the reappearance of the Bubble Shield, but can only be used by Classic Sonic. Classic Sonic can use this move by double-jumping.

Sonic Lost World
The Bounce Attack also appeared in Sonic Lost World.

Trivia

 * A trick with the bounce attack is a move dubbed a "Super Bounce" where tremendous amount of vertical distance is possible. To do this, you spin dash into a wall. Upon collision you press A then B in a split time frame. Because a bounce is determined by the velocity of the downward bounce, unnatural speeds cause a giant bounce. This allows the player to do multiple tricks, such as getting back onto the first roadway of City Escape.
 * In Sonic 3 & Knuckles, if the player does a Bounce Attack, the player will be bounced higher than normal.
 * Sonic's bounce attack in Sonic Adventure 2 works in a similar way to the Butt-Bounce ability in the Pac-Man series.
