The Flash is often considered one of the fastest characters in fiction. He can run at super - speed, which allows him to break the speed of light and perform amazing feats like time - travel. His super - speed gives him an edge in battles and enables him to reach any destination in a blink of an eye.
It's hard to pinpoint just one, but characters like Sonic the Hedgehog are known for their extreme speed in their respective fictional universes. Different stories have different fast characters depending on their powers and settings.
In many fictional universes, Sonic is often depicted as one of the fastest characters. But it depends on how you define 'fast' and which fictional characters you're comparing him to.
Determining the fastest character in fiction is quite subjective. In some cases, it could be Quicksilver from the X-Men universe for his super-speed abilities. However, it really depends on the specific criteria and context of speed being considered.
It's hard to say for sure. Different fictional universes have their own fast characters. Maybe The Flash from DC Comics could be considered one of the fastest.
