Dude that is rediculous if you read any flash comics. Post a scan of him doing that stuff to some well noted high level characters in a solo fight.... Right because there are no scan because that stuff only works on his enemies like the rogues or zoom, it's not going to work on a person that's on supermans level, or at least not good enough to get him a win
Yeah you're right Flash has never harmed someone who was really stron--
In this specific scan, the combined powers of everyone in Pre Crisis DC Earth could only put a single hole in Anti Monitor's armor before he defeated them. Wally completely destroyed his armor (while admittedly losing the fight). He has also clearly KO'd guys like Mongul and Martians in single hits when he doesn't hold back.
If Wally's truly fighting to the best of his abilities then I don't think there's an argument of whether or not he can harm Surfer. He can. The main question is if Surfer can kill Wally while he deals with the rest of the Justice League. In this scenario, Wally will almost certainly take out who he sees as the biggest threats -- Superman, GL, Wonder Woman. He has experience with them and he knows exactly how powerful they are and he has practically no knowledge on Thor or Surfer so it is unlikely he would go for them first. Surfer could possibly act in the time it takes for Flash to kill them, he could possibly not. I've had more than my fair share of tedious Flash vs Surfer debates so I'll avoid the meat of this thread, just chiming in to point out that Wally's best feats are literally never against his rogues, because he has never, ever had to hit his Rogues as hard as he can and he never would because his goal is not to atomize them.
