We all have our “off” days! Who could get the best of Superman on his?
Batman
I second that!
Mxy, on any given day of the week. That dude doesn’t realize how strong he really is.
Anyone who the writer wants to, but throwing my favorite Kryptonian into the mix on who can go up against him.
Kara giving a whooping to Injustice Supes for losing track of what the El name means.
CW Kara taking down Kal on bad kryptonite.
Captain Atom.
There are lots of answers to this question, because in any fight he’s in- Superman is going to be the favorite to win. Everyone loves to root for the underdog and it’s a fun story to write/read. So the possibilities are almost endless.
I watch a lot of MMA, so the thing to remember for us Superman fans is that winning one fight doesn’t mean you’ll win every fight. So saying something like “Batman could win” doesn’t mean he’d always win.
Now having said all that, here are a few-
Lex Luthor
Shazam
Wonder Woman
Theoretically, I think Zatanna could do it. Everyone forgets that magic is Kal’s second biggest weakness, and she could probably change the radiation from yellow sun to red sun radiation as well…

That is a amazing picture
I also think Firestorm could do it. In Justice League Action he was able to more or less reverse engineer kryptonite to change it so by that logic he should be able to transmute something else into Kryptonite. -C
I’m surprised that nobody mentioned Doomsday
It sure is.
Captain Marvel: Magic
The Atom: Shrink down and mess his brain up or insert Kryptonite into his brain
Firestorm: Turn into or create Kryptonite
Martian Manhunter: Psychologically break him down.
Lois Lane. She’ll win every single time
In the same vein, Ma and Pa Kent
@ZatannaAndHerSpells, Superman 2nd weakness is magic! ETINOTPYRK NIAHC RAEPPA!!!
Good luck Superman, you’ll need it!
Off the top of my head?
Batman
Dr. Manhattan
Zatana
Dr Fate
anybody else with magic
Shazam/Captain Marvel

I’d like to think GL could.
Any number of magic characters as people have pointed out, but…
Firestorm. I mean, right? Superman has limitations and is literally made of organic matter. Even Prof. Stein says the power of the Firestorm Matrix may be theoretically infinite, harnessing the spark of creation.
