When performing the Burning Straight, Knuckles launches himself forward fist-first in midair, thereby increasing his horizontal speed to gain distance, while assuming a pose akin to when he is gliding.
In gameplay, the Burning Straight is useful for crossing larger areas when sent flying into the air or preserving Knuckles' momentum when falling to the ground, all while allowing him to damage any foe in his flight path. Additionally, the move will not cancel the momentum Knuckles receives from the Boost Mode. Also, upon landing from the Burning Straight, Knuckles immediately rolls into a Spin Attack which can damage foes.
To perform the Burning Straight in gameplay, the player must press right/left on and the R Button at the same time after being launched into midair by gimmicks like the Spring or Ramp. The direction Knuckles heads in is determined by the direction pressed on .
