Time Break in Secret Rings and Generations, Sonic does use Chaos Control against Shadow, Sonic can sus out patterns and weaknesses of characters while fighting, like finding out how to harm Chaos or Solaris near instantly
Wisps are standard equipment for Sonic yes, Ichikoro Gauge is durability negation, it’s the super move of Sonic battle
Oh thank you for telling me about the Time Break, the Ichikoro Gauge, and correcting my SA2 knowledge.
The Ichikoro Gauge has never been used outside of Sonic Battle, but i'll ignore that. The Ichikoro Gauge can be countered by Flashes Phasing, but I believe that Flash does not commonly use phasing in character, even against tough opponents. Ichikoro Gauge is a win-con, but it's only if this fight is long and drawn out due to the fact that Hyper Sonic will have to sustain noticeable damage in order to use it, and I think that it's likely Flash will use speed steal first.
Time Stop from both parties is negated by the others ability to also use time stop, disabling any way for anyone to out speed each other.
Wisp is also a valid win condition for Sonic to use, but, Flash can out speed Violet Void, since Black Holes are moving at a speed much slower than Flash and Sonic are. It's literally in one of Wally's feats that he outran a black hole.
I looked at weaknesses for Flash and let me eliminate those since you said the sus out patterns of weaknesses.
- Flash's accelerated metabolism is irrelevant since he has his connection to the speedforce, as shown in the stamina tab.
- Sonic doesn't gain his speed from time manipulation, so this is fine
So current wincons are:
Sonic's:
- Violet Void (by catching Flash off guard, which is possible, otherwise Flash can out speed the Black Holes pull, and Sonic would be unable to spam Violet Void)
- Ichikoro Gauge
- Being BFR'ed (if he uses the speed force too much, he'll be trapped in the speed force and the victory will be given to Sonic)
- Time Stop (despite my earlier statement, Flash lacks complete control of his Time Manipulation powers, so Sonic may be able to find a way to out speed Flash, but this one is unlikely since Flash has the power of the entire speed force and should have higher control over his abilities)
- Precognition (can be alerted if Flash attempts to sneak attack him)
- Yelling (if Sonic yells, he can stun foes. If he uses yelling, then he can follow up with Violet Void, but this isn't in character for Sonic to do)
- Resurrection (despite the fact that this probably isn't a death battle, Sonic can revive himself upon death)
- Speed Up (probably not allowed since speed is =, but Sonic can increase his speed to outpace Flash)
- Accelerated Development (may be able to copy all of Flashes win con if he survives them, and may be able to learn other abilities of the Flashes as well)
- Invisibility (even though it may not be in character, he may be able to combo invisibility with another wincon to have a surefire win)
Flash's
- Speed Steal (Flash can steal Sonic's speed and then blitz him, but this is not commonly used IC)
- BFR (can throw Sonic into the time stream, or into the speed force, this is in his post crisis key which he should be capable of)
- Time Travel (can make it so that he fight's Sonic back in his Classic state, which he's significantly weaker in, Flash has stopped using Time Travel though, seeing it as irresponsible)
- Intangibility (doesn't use it that often)
- Major Range Advantage (Low Multiverse < Low Complex Multiverse)
Yeah, I don't have nearly enough knowledge on the Flash to find any appropriate win cons, get a Flash supporter in here! ALSO DID SOMEONE ATTEMPT TO ADD SONIC FORCES JANKY PHYSICS AS RESTRICTED FLIGHT AND SUCCEED WHAT THE FK!
Yup, originally went for the obvious pick, but Sonic has a lot more win cons that are weaker than Flashes.
