I notice how people go on about how batman needs prep time to actually win something. What of superman?
How dangerous could he be if he got prep time before every fight?

prep time superman phantom zone projector or superman robots../

Phantom zone projector, superman robots, braniac technology, kryptonian technology or some other space weapon that he keeps in his fortress.

@kenshima15: Watch Superman vs The Elite :) IMO a pretty good example of Supes with prep time.

He'd destroy the universe.

Haha, Superman has used the Phantom Zone frequently in the New 52, even BFRing the moon-sized Warworld. And when he isnt sure how to deal with someone, or unsure about how much of threat he's dealing with, he is willing to BFR to the 'Zone first and ask questions later.

that's how he took care of zod, ursa, and non in the superman II movie....with prep, that's a logical explanation showing 1 kryptonian vs 3 kryptonians.
