The Bounce Attack (バウンドアタック,Baundo Atakku?), also known as the Continuous Bound (連続バウンド,Renzoku Baundo?), Bound Jump, Bound Attack or simply Bound (バウンド,Baundo?) is a move used only by Sonic the Hedgehog. It first appeared in Sonic 3 & Knuckles, and has since become once of Sonic's most used techniques. The Bounce Attack allows Sonic to perform a downward attack.
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 the Hedgehog 3 & Knuckles
The Bounce Attack first appeared in Sonic 3 & Knuckles where it is called Continuous Bound. 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 , or 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 , or 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.
The move reappeared in the following game Sonic & Knuckles and locked-on version, where it function in the exact same way.
Sonic Adventure 2

Sonic Advance 2
The Bounce Attack first appeared on the handheld in Sonic Advance 2and is performed by pressing while in mid-air or pressing while holding down on while launched into the air by gimmicks such as springs, serving as his downward Mid-Air Trick Action. When using it in this game, Sonic stops mid-flight when using the Bounce Attack and leaves after images when used. This can be used to open pathways under Sonic.
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 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.
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.
