Flash redesigned by Aaron Diaz:

Origin: While attempting to replicate what he believed to be the origin of Superman’s invulnerability, Dr. Ananth Patil accidentally accelerated his own metabolism to a superhuman degree. While he has gained extraordinary abilities in the process, his body has become unstable, requiring him to eat enormous amounts of food simply to stay alive and making regular sleep impossible. He currently seeks out other superhumans, hoping to find a way to cure his condition.

Powers: The Flash can and move at incredible speeds, well past Mach 10. He has also devised a helmet that compensates for the Doppler blue shift he sees at very high speeds as well as the equivalent for sound with his ear microphones.

Notes: I wanted a different take on the Flash than what’s usually seen, namely someone who saw it more of a curse than a blessing. Ananth is a scientist first, he’s more like Hank Pym or Bruce Banner: adventuring is a means to an end. Visually I wanted to give him a build that was more like a sprinter with larger thighs and a leaner overall shape. His outfit is very deliberately designed (by the Flash himself), with an emphasis on comfort and practicality.
