Strongest person Lex Luthor can beat with prep ?

Not superman, apparently...

So anyone bellow supes.

I would say Goku.

@wbr17: Oh, come on man.

You know the hero always has to win(eventually).

Otherwise, he'd already have killed Superman.

And Supergirl.

And hundreds more kryptonians, at the same time(by converting the sun from yellow to red).

Superman's had his ass saved by others or plot plenty of times, as all heroes have.

Anyone if he get's enough prep...

Not superman thats for sure, so il go with Grodd, assuming he also gets prep

PIS or No PIS?

How much prep?

Morals Off Martian Manhunter.

Maybe Superman on a good day.

All of DC

Batsy(with prep) and Sups

Not Batman.

pretty much anyone

What would prepping for Goku even do? Lmao. He has no weaknesses. And can currently shake the Universe with the shockwaves of his punches. Where is the prep for that?

-Enhance his strength or get someone/something that is near his strength
-Maybe even create a ki dampening device or something

Any character already thought to be able to be beat by batman without batman's martial arts or physical strength.
