Color of his skin, hair, eyes, genre, etc?
Who is the fastest superhero ever?
There are several contenders.The FlashLikely the first one everyone thought of, the Flash tends not to run any faster than Mach 10 (3,402.9 m/s), as that causes damage to the environment around him. Some incarnations of The Flash are said to be able to run at the speed of light (299,792,458 m/s).SupermanAccording to Comic Vine, Superman's in-space flight speed is superluminal, which means faster than the speed of light. This would make him faster than The Flash. Superman Prime, with thousands of years spent in the sun, can apparently fly at many thousands of times faster than the speed of light.Sonic the HedgehogAccording to What is Sonic the Hedgehog's maximum running speed?, Sonic maxes out at 3,840 mph, or 1.716 km/s.Silver SurferSilver Surfer quickly scouts out distant planets in very little time, indicating he can travel much faster than the speed of light. It is unclear precisely how fast he can travel.GokuGoku's instant transmission technique is said to travel at the speed of light, however it appears to be able to teleport him to any location in the universe instantaneously. This is much faster than any of his competition. If instant transmission is not included in the competition, this thread puts his travel speed at SSJ3 around 200,000 m/s.Living LightningAn Avenger who could move at the speed of a bolt of lightning, which is about 5,954.5 km/s.Overall - It depends on how you define it, but it's probably Superman, because he's a pure power fantasy, while other heroes are built around rules.
