Your posts say more about you than you can imagine.
By going CBR I mean your apparently assuming that John would operate in this battle as if you were controlling him.
Seriously, starting off invisible and intangible followed by dropping a mountain on the battle field? GTFO.
Wally would absolutely eat John for breakfast if he was in that mindset. Screw John's level of super speed. Wally would recite the Mantra and he'd be nothing but a statue. He'd then go on to pulverize him like he did the Anti-Monitor.
In that same issue he was moving so fast he was invisible to Pre-Crisis characters including Superman and was able to amp some of the assembled heroes to the point either Supergirl or Powergirl stated they had never felt like they did at that moment.
So do you think Wally can do the same thing to Surfer, or Thor? Superman? Because MM has a leg up on all of them. He can read wally's mind, put up psy shielding so that Wally run's smack into psy shielding, etc.
Well you need an object to carry that kind of energy though

not really... even subatomic particles move...the whole universe is on constant motion so speed is everywhere...
in DC in particular there is even a source of speed (the speedforce)
Wally got IMP..or he can just punch MM at lightspeed a thousand time before MM can react..Wally can go intangible too..he can even hit MM while MM is intangible..if MM is throwing mountain..do u think Wally is just gonna stand there??do u think Wally is dumb??and lets not go to the speedsteal..come on dude..u know Wally at his best is to much for MM..
