Which villain would be Superman's worse Nightmare

Alright I am talk like people under Thanos level as a cap but nobody below Wonder Man level close to Supermans level of villians. Marvel Villains only who would give him the most trouble but make it interesting, and would just make his life hell? No cap on the kind of powers the villain has cosmic, natural, magic etc etc

Villains
Graviton
The Unspoken
Ronan
Shadow King
etc
etc

Lois with some crazy power.

PMS Lois.

She is not Marvel

Loki or Creel

Graviton would be an awesome villain for Superman.

Not sure if he's fast enough to cope with Superman, but he's definitely powerful enough and he should have the brains to be more than just a physical threat.

Doom.

Loki would own him.

Super Adaptoid

Godzilla

Wrecker would wreck him.

Just wondering do you guys think that Quasar is a solid hard counter too kal? It seems that his powerset can be extremely dangerous to him.

Apologies didn't read the OP in detail it says villians on the same level. I would go with ultron.

His powerset is dangerous to superman, he isn't that dangerous though. This isn't CBR.

Shadow King.

Nightmare.
