Knuckles' pose when using Power Flash.

When performing the Power Flash, Knuckles thrusts his right fist forward and shouts "Take that!" He then releases a flash of light that disables the opponent's movements for a short time.[1] The opposing player's screen will then be covered in a pink tint and a counter counting down from ten appears. This effect leaves the opponent completely immobilized, making it an ideal way for the user to gain the upper hand. Power Flash lasts for ten seconds, which is indicated by the counter, though the opposing player can reduce the time by rapidly pressing any buttons.

Power Flash can only be performed by playing as Knuckles in the game's two-player mode. To use it, the player must press SNNBGAMECUBEDISCO/Gamecube X Button on the ground after collecting sixty Rings. To use it again, the player has to collect another sixty Rings.
