It depends on Sonic's form, see Sonic in his normal form can run at a speed of about 762 mph, but the speed of sound is only about 761 mph. Therefore, Sonic is 1 mph faster than the speed of sound, and that means that he breaks the sound barrier. If referring to Super Sonic, Sonic's speed, power, and stamina increase 1,000 fold which gives him a speed of approximately 762,000 mph. Hyper Sonic is Sonic's most powerful form which increases his speed 2,000 fold which adds up to a speed of 1,524,000 mph.
Light is for sure faster, and If you want to know what is faster than light its sound.
no light is faster
Light travels faster than sound ... about 875,000 times faster. Nothing travels faster than light.
Tachyons are theoretical faster than light particles.
Sonic is faster. The road runner is fast, but sonic is as faster than sound.higher than roughly 350,000 km. He is the fastest thing alive.
Sonic can only run faster than light in the Archie comics. His fastest speed in the games is exactly lightspeed.
Of course sonic is faster. Sonic can travel up to the spped of light and faster. A bear can only go 40 MPH. a car can go faster than it. Sonic the Hedgehog is by far the fastest thing alive.
Sonic, he can reach speeds faster than the speed of light in the archie comics and can reach beyond with his alternative forms ^^
I'm not sure who or what 'sonic' is. But it doesn't matter. The answer is 'no' regardless.
that would be a hard one sonic runs at full speed 749mph but superman at full speed flys 100000000000000000000000000000000000000000000000000000000000000000000000000000000000000000mph but in sonic and the rings sonic runs 10000000000000000000000000000000000000000000000000000000mph so superman is faster but if sonic went sonic unleashd and did a sonic bost he could run faster then the speed of light and he never ends in speed sonic would just get as fast as he wanted to so all together sonic the hedgehog is faster then superman and anything else go!!!!!!!!!!!!!!!!!!!!!!!!!! sonic the hedgehog i think sonic because sonic is even faster than cheetahs:D
Sonic is the fastest Hedgehog Rainbow Dash She can obtain mach 10
No, super Sonic is faster.
Flash is faster than sonic by a long shot, he can run through walls and solid objects. Also when he is using speed force he is invincible and becomes 10 times faster than sonic. To add on if they were to race each other at their normal form and starting speed, which for sonic is sound speed and for flash is light speed the flash would thrash sonic.(say it did answer your question if you think flash is faster and say no if you think sonic is faster)
Science fiction.
sonic is faster. sonic is the fastest thing alive.
