How fast can Sonic the Hedgehog run?

Answer 1

Sonic the Hedgehog, on average, is known to run faster than the speed of sound. Sonic could instantly accelerate faster than the speed of sound with ease as shown in sonic x episode 1. He could increase his speed by using his Super Peel-Out technique, as shown in Sonic the hedgehog cd, Sonic Chaos, Sonic Triple Trouble, and Sonic Blast.

In Sonic Adventure DX manual it states that ''He's the world's fastest, hypersonic hedgehog'' which is at a staggering speed of 3,840 mph.

In Sonic Adventure, Sonic Adventure 2, Sonic Heroes and in Sonic generations, Sonic can move at the speed of light, as seen by his specific light speed set of moves. Those moves include the light speed dash and light speed attack.

In super interactive annual 2014 sonic the hedgehog book in his profile in the guidebooks. It states that sonic is faster than the speed of light.

In Sonic Colors (DS) -Omega made calculations from Sonic and remarked that light speed would be exceeded by him, and Sonic replied that light speed is too slow for him (I think you know how Sonic feels about slower things).

In Sonic the Comic: Hyper Sonic #134: Something about 2 missiles on opposite ends of continents about to hit. He pushed himself to his extreme limit, and really straned himself, entering a realm where time was stopped. He then proceeded to take out the threats in no time. After this, he had trouble getting out of this accelerated mode and was nearly stuck permemantly , until he found how to slow himself down to get out of it. So basically, sonic moved at the speed of infinite, because he was moving from one location to another in NO TIME.
