Huh? Still a bunch of people with Surfer here, eh? Is the JLA getting a GL in this fight? I know Surfer's a beast but everyone's assuming a lot.
Supes/WW/Aquaman/etc. wrestle him to the ground. Flash ties WW's lasso around him a few thousand times. Diana holds him while Flash helps her dodge his blasts, and the rest of the crew beats down on Surfer.
Add that to trying to fend off a telepathic barrage and energy from Supes/MM/GL etc. and he's got a ton to think about. Even if he "intagible's" out of the lasso, hitting anyone with Flash on the loose, or doing much damage without taking a bunch himself would be hard.
I realize he could take out any one or two of these people. And he's clearly the most powerful in the fight (except perhaps for a super-pissed and/or inspired GL), but I'm surprised everyone's willing to concede the majority to him.
And yeah, Surfer's fast. But when has he shown in-fight speed that would prove he won't get hit by any of the JLA's herald-levelers, many of whom have impressive speed feats? I just can't see him taking this any number of times.
{edit} I see I'm not the first to think of the lasso technique...didn't want to steal anyone's thunder.
