Superman - "Hey buddy stop hurting all these people"
Loki - "**** off Mortal"
Superman - "Alright im gonna have to stop you NOW!"
Swings at a illusion, and Loki come from behind and taps him with his brainwashing spear.
End
Not saying Superman is not more powerful than Loki but he just is kind of a dummy. Loki As arrogant as he is knows how to fight and use his powers, cleverly.
