Speed can move, think, & react at superhuman speeds. His entire body is adapted towards the rigors of high-speed running, including his cardiovascular & respiratory systems. He metabolizes an estimated 95% of caloric energy content of food (normal human use is about 25%). Speed's musculature is enhanced making him virtually tireless due to his metabolism not producing fatigue-building poisons. His body constantly expels waste products through his accelerated respiration through exhalation. His tendons have the tensile strength of spring steel & his bones can withstand the impact of traveling at high speed to his bones containing unrevealed materials significantly more durable than calcium. Speed's practiced reaction time is about five times faster than a normal human's & the speed at which his brain processes information is heightened to a level commensurate with his bodily speed, enabling him to perceive his surroundings while traveling at high velocities. Speed's body has an invisible aura that prevents his clothing from being affected by air friction as he moves at high rates of speed.Speed can travel up to 175 miles per hour & can run at this average speed for about 4 hours until he needs to replenish his energy. Speed can run up the side of a surface at speeds up to 250mph over water & up vertical surfaces before gravity overtakes him.By rapidly vibrating his hands in close proximity, Speed can create hyperkinetic vibrations that he can throw at objects, causing its atomic matter to accelerate & destabilized until it explodes.
