Who can beat the Flash with prep?

Flash is bloodlusted

Batman
Lex Luthor
Iron Man
Reed Richards
Dr. Doom

All of them can.

Batman doesn't need prep, he just no-sells Flash's IMP, tells him it's his turn and punches Flash's head clean off.

Pretty much.

So can

Vrill Dox II
Pym
Atom (palmer)
Mr Terrific
Banner

^You don’t think Black Panther can do it?

Yeah actually.
BP could too.
Just listed the first few who came to mind.

There's probably quite a few more.

With prep?......any of them.

Wow. We all agree.

The only question is... when DarkSaint will crash this party and break the combo?

....

All can, except for Tony. His Flashbuster suit would do well, until Wally kicks it up a notch and kills him.

If time travel is involved, only Doom does it.
