..aside from obvious street leveller non super powered types, what do you reckon?

If you're talking more of the mid tier guys, he could maybe beat someone like Clayface.

he would easily beat every single villain of batman, Peter is far stronger than batman's strongest foes (killer croc, bane)

Depends.

It would probably be easier to make a list of the guys who he cant beat.

@ariesxmasters:

that would be alot easier:

hmmm. let me think:

darkseid, and anyone who has beat the crap out of superman

Pretty much all their street levelers.

And some of their mid-teir characters.

On the Justice League? Cyborg, Batman are all.

Any characther that a writter want to do it.

he could take down batman.

@paperdemon: yup. if Peter were to hit batman for real in the face, Bruce would end up with no face

@angelalfonso: exactly

He could beat alladem.
