Lol... why do you debate like this? It's hilarious to me. Hulk have abstract level strength. Thor has Chaos King damaging level blasts. Thor have Celestial tanking durability. Thanos have Galaxy level durability.
Let's make this even sweeter. Surfer took on two Galactus level beings and endured their attacks AND beat them.
Point 1: you argue that comic Flash is different from forum Flash. Rebuttal: Actually, comics show Flash doing everything forum Flash is said to be able to do
Point 2: Na-uh! You're using single showings! Rebuttal: Single showings of.....comics? IOW, COMIC Flash = Forum Flash?
Point 3: Well, well, errr in that case, Surfer (and it's always Surfer) does XYZ to Superman (and it's always Superman). Rebuttal: NOW forum Surfer is very different from comics Surfer. If you have the scans to prove XYZ, just like Flash fans do, then post them.
Point 4: Errr....here is an unrelated scan of Surfer channeling the Crunch and nearly dying in the process. Rebuttal: That's.....that's not adamantium or cosmic awareness to pinpoint weaknesses.....
There you have it, carvster. All summarised for you. As usual, you make silly comments, then backtrack and slip and twist in an effort to escape. I'm surprised you didn't try to stretch the page and scan dump with unrelated scans, and only limited yourself to one!
As for the thread, yes, Flash can beat them. He would have to pull his high end showings out, of course, but that is testament to the formidability of his opponents here.
