Superman 642.
Superman is even standing still, watching Wally, and waiting.
"I hesistate, just long enough to let them each finish their moves. I hear Dinah inhaling, readying a scream. Carter comes high, preparing bruce force. Wall crosses low, moving to flank. When they're all where I want them. I move. Wally is fast enough to see it coming-- but not fast enough to do anything about it. "
By the time Superman leaves, Wally is the only one standing however, but I'm guessing he got BACK up after being dropped once already. [Superspeed metabolism/healing] Since he was right in Superman's face for a few panels, then not there and everyone else that was standing is scattered across the ground, but you can't see all of them. In one possible scenario there, Wally got wholloped, in another, he just wasn't fast enough to catch him. Either one kinda proves it right?
Not to mention he was punching through GL constructs while this was going on.
