Shadowflash, a 33-year-old cheetah, stands 6'1" and weighs 195 lbs. In addition to the standard Felid and cheetah abilities, he also has the power to "blink", or teleport within a line-of-sight range. His skills include leadership, tactics, strategy, gymnastics, firearms, and brawling.

Taken in by a "man in black" at an early age only to become a weapon of war, Shadowflash has no knowledge of his true name, family, or past. He leads a black ops team (which includes Ecstacy, Fyro, Shanzi, and Styx) for an unnamed branch of the government.
