soinc would win no more questions
Flash because he would SSP (super sonic punch )Vader
flash -.-
The Flash, he would steal Sonic's speed. Plus Sonic wouldn't be able to touch the Flash, especially if we are talking about Wally West here, the fastest of ALL the Flashes. Sonic can only go faster than the speed of sound. Flash is faster than the speed of light.
I think sonic is better because sonic is the main character and if flash were better he would be the main character
Although this answer is completely opinionated, SONIC WOULD WIN FOR SURE!!!
I think it would be sonic
sonic
Sonic
no darkspine sonic in ultimate flash sonic
Sonic would win the fight, but sora would put in one hell of a fight.
The only way to answer a (pointless) question like this is to consider their abilities within their respective canons.Flash is routinely shown as being capable of exceeding the speed of light by a relatively large factor in his comics.Sonic is... much, much slower than that, at least in the games. I don't know how fast he's claimed to be in his comic books.I suspect that in a Sonic comic, Sonic would win, and in a Flash comic, Flash would win.
Batman would beat Sonic.
