When performing Bat Guard, Rouge says "Are you ready for this?", while doing a spin in mid-air and holding her arms out. Rouge will then release six red-glowing bombs with bat wings that will begin to hover around her, while still allowing herself to move around freely. These artificial bats will then keep surrounding Rouge for as long as there are energy in the Signature Meter, which begins to deplete once Bat Guard is active. In gameplay, the player has to press to activate this move.
Whenever each of Rouge's bombs make contact with an enemy, be it Badniks or the opposing rival that Rouge is facing, they will explode. For badniks, these bombs will destroy them in one hit, while for the stage's rival, it will damage him and leave him stunned for a moment. If all these bombs are used up, the Signalture Meter will instantly be emptied.
While Bat Guard is active, it can be used for both defense and offense. As defense, while the bombs surrounds Rouge, they can act as a damaging shield. As an offense, while Rouge still have some bombs surrounding her, she can grab them and throw them at any nearby enemy one by one as an attack, while the bombs automatically home onto the target when they are within range. In gameplay, the player has to press to throw the bombs one at a time.
