Storming Heart

The Storming Heart is one of Amy Rose's special moves in Sonic Adventure 2 and Sonic Adventure 2: Battle. It can only be performed when playing as Amy in the game's two-player mode, but only when she has gathered enough Rings.

Description
When performing Storming Heart, Amy begin by blowing a kiss with her right hand while saying "yeah". Amy will when create a small, but concentrated whirlwind, made several transparent pink hearts that will wrap around and ensnare her opponent, wherever the opponent is located, causing damage.

In the games' two-player mode, where two players go up against each other in race to the Goal Ring, the player controlling Amy is able to execute the Storming Heart. However, in order to gain access to the Storming Heart technique, the player must collect at least 20 Rings. Once the player has collected enough Rings, the Storming Heart can be performed freely. In two-player mode, it is nearly impossible for the opposing player to avoid Storming Heart, unless the other player is Metal Sonic, who can use his Black Shield to protect himself from these type of attack.
