How powerful is Pre-Crisis Superman

Could he even harm a Skyfather though?

Not in any meaningful way, no, but basically as far as the group that is nebulously between the usual Class 100 crowd and skyfathers, PC supes is the top of the line, to put it one way.

The only real limit on Pre-Crisis Superman is, the only things he can't do are the things he hasn't tried yet. There was one time he just decided to stop being vulnerable to magic. Literally he spent one page thinking about why he had that problem, then decided not to have that problem anymore, and he didn't. And he's not just MFTL, he can break the very concept of finite speed beyond what even Flash could or can do.



After Justice League I've seen people asking "Why does he even need the team?" That's not a new concept.

There were a variety of limits on pre crisis Superman, but I can see why you would try to argue he's infinitely powerful.
