Barry Allen is a forensic specialist for the Central City Police Department. There is no shadow on his record or his past. And when he is the Flash, he may move too fast to even cast a shadow.
Years ago, Barry Allen was working late in his laboratory when it was struck by lightning. The bolt struck him as well as certain chemicals in a nerby cabinet. The chemicals -- their composition changed by the lightning -- exploded in Allen's face and transformed him into a being who could move at super-human speed. There is no place Allen cannot be in seconds, no foe he cannot outrun or outrace. He has trained himself to vibrate his molecules at such high velocity that he can pass through walls and even ste into different dimensions and eras. 
- Speed Force Conduit: Speed force conduits possess a connection to the Speed Force, a cosmic force that allows its users to push the boundaries that keep time and space. As a conduit of the Speed Force, all aspects of their physiology are accelerated and enhanced.
- Accelerated Healing: By having a connection to the speed force, every speed force conduit has an incredibly fast healing factor and can heal from most injuries in seconds and devastating injuries in minutes.
- Enhanced Senses: The Speed Force enhances the speedster's senses, allowing them to perceive and process thoughts faster than the normal person.
- Phasing: Speed Force conduits can tap into the Speed Force to vibrate their molecules in a way to achieve intangibility for short bursts, allowing them to phase through objects.
- Speed Force Aura: The Speed Force manifests an aura around the speedster and whatever they are carrying, protecting them from adverse effects of their speed, such as friction with the air.
- Superhuman Stamina: The Speed Force grants its conduits with a great increase of stamina, allowing them to fight or run much longer than the average person. Although a great increase, it is not unlimited.
- Superhuman Speed: The universal factor of being a Speed Force conduit grants its user with imperceptible amounts of speed. All powers that conduits possess derives from their speed.. This also confers:
- Superhuman Agility: The speedster's agility, balance, and bodily coordination are enhanced to superhuman levels. This allows them to easily maneuver while moving at superhuman speed.
- Superhuman Reflexes: In conjunction with their enhanced senses, The speedster's reflexes are heightened immesurably, allowing them to dodge or react faster than normal.
- Vortex Creations: Speed Force conduits are able to create vortices of air by running in circles or rotating their extremities at super-speed. These vortices can be used for a number of effects.
- Overactive Metabolism: If Barry runs too fast for too long his metabolism can harm him and slowly kill him.
