The exact nature of Daniel ("Danny") Cooper's heritage is currently classified, but it is believed that he is the son of Quantum. Danny has tanned skin, brown eyes and light blond hair, and is tall and thin.

Like his alleged father, Danny has the ability to move at incredible speeds, and even - it is rumoured - pass through solid objects.

Of all the New Heroes, Danny is the most well-known and popular, although is has been speculated that this popularity has been artificially generated: once his identity became public it was decided that Danny would become the public face of the company, thus helping to shield the team's other members.
