Is there any character that Superman cannot defeat besides Thanos?
Strange question, but yes.
Superman is undeniably powerful, being one of DC’s strongest heroes. However, he does have his limits.
For starters, Thanos and Superman are from separate companies, with Thanos being a Marvel property. That being said, I do believe that Thanos could defeat Superman in a fight, though the reverse can also be said.
Now, to answer the question, there are absolutely characters Superman cannot defeat, regardless of circumstances (unless he’s massively amped or certain plot devices are used).
I don’t see Superman ever defeating The Presence, DC’s end all be all god.
The same can be said for The One Above All, Marvel’s god.
There are other characters of course, however, as a baseline, Superman isn’t generally (or ever) defeating characters on/above Galactus’ level. That would include beings such as Dormammu, and Trigon, as well as even stronger characters like Eternity and The Living Tribunal.
Superman is strong, but he ain’t that strong.
