Aquaman vs. Loki: Spearmatch
This is pure melee combat. Aquaman has his trident, Loki has his scepter from Avengers. NO POWERS. Meaning no illusions, mind-control, energy blasts or unlimited daggers from Loki. No super-swimming or talking to fish from Aquaman. Both combatants are in full armor and going for the kill. Fight takes place in the Stonehenge. Who impales who?
Bonus award: Who has the better armor?
