Superman hits harder than cap's zeus amped punches and is actually able to KTFO Dreadnaught. Before somebody asks that force-field was there so that Psi-phon doesn't dampen his powers again.
Conclusion? Superman wins 6-7/10. [/B][/QUOTE]
There's context, though.
For one, Clark didn't even have his powers when he finished Dreadnaut.
He's the one that called in the JLA, knowing they'd be fed by Psi Phon into Dreadnaut. He was counting on it.
Basically, he gambled Psi Phon couldn't help but feed powers to Dreadnaut to duplcate, and gambled on shorting them out.
