Are there any canonical references to how fast these two are, for comparison?
Trick question, Sonic is Barry Allen’s fursona. They run at the same speed because they’re the same person
I never thought about it before, but now that you mention it, I have never seen Sonic and Barry Allen together in the same room at the same time
Sonic is faster. The Flash isn’t real.
Whoever the writer thinks should be faster, so as to serve the needs of the story being told.
In every single conversation about which fictional character can beat the other in any competition, this is ALWAYS they correct answer.
Neither are as fast as my friend Ryan after he got his new shoes. He was so fast. Like really really fast. But he got hit by a garbage truck and can’t walk without a cane now. His mom works at Waffle House. His brother plays Fortnite on Switch.
P.F. Flyers?
No, he had Yeezy’s. This wasn’t 1964.
That was Benny “The Jet” Rodriguez
Both can go faster than light and “therefore” break through dimensional thresholds or go backwards in time; at that point actual measurement is kinda pointless. However, Flash is bound to the Speedforce (of whatever dimension/timeline/etc he’s in) and when that’s shared with any other speedsters, he becomes less capable. Sonic does not seem to share this “weakness” therefore would be considered faster.
This is the same argument for why Superman is actually faster than Flash, too. And ignores the use of chaos emeralds.
The only fictional character I think could possibly move faster is MAYBE Superman in some of his more broken appearances.
You simply arent going to get past the insanity that is the “Speed Force” and I don’t think Sonic is going to trick West or Allen.
