Sa Superman VS Thor
Thought Robot Superman- Hardcore stomps Necro Thor.
SA Superman with the Sword of Superman - Stomps Thor (Sword makes Supes Universal)
Superman Prime One Million (Golden Superman)- Not enough feats, but should stomp with what we know of him.
Prime-Trapper (Superboy Prime as Time Trapper) - Stomps Thor
SA Superman - Depending on scenario: Outclasses Necro Thor if feats are taken into consideration. However, SA Supes is notoriously vulnerable to magic.
Superman One Million (Kal Kent) - Interesting Fight. Should give Thor a good fight with his plethora of powers.
Superman Prime (Prime With Guardian Amp) - Interesting Fight. The magic immunity/resistance Prime has is going to be some what of a game changer.
