Mjolnir's enchantment power gives Thor the slightest edge over Diana's superior combat skill.
Two divine warriors โ one Asgardian, one Amazonian โ with remarkably similar power profiles. Both have godlike strength, divine weapons, centuries of combat experience, and the warrior spirit to fight until the universe ends.
Wonder Woman is arguably the more skilled warrior. Trained from birth by the greatest Amazonian fighters, Diana's combat technique is virtually flawless. Her bracelets of submission can deflect Mjolnir throws, her lasso compels truth and can bind gods, and her sword can cut at the subatomic level.
Thor's advantage is Mjolnir's versatility. Beyond being an incredibly powerful blunt weapon, it channels lightning, creates portals, and in certain versions can manipulate time and matter. The God-blast โ a concentrated release of all Thor's divine energy โ is a trump card that exceeds anything in Diana's arsenal.
In terms of raw strength, they're remarkably comparable. Both have moved planets and fought cosmic threats. This fight would be an absolute war of attrition between two divine warriors who simply refuse to fall.
Mjolnir's enchantment gives Thor diverse attack options beyond physical strikes. His lightning is a ranged weapon Diana must respect, and the God-blast is a fight-ending trump card. Thor's Asgardian durability also means he can absorb more punishment than most divine beings.
Diana is the superior technical fighter with better training and more refined combat skill. Her bracelets can deflect anything, her lasso can bind gods (including theoretically Thor), and her speed feats in certain continuities match or exceed Thor's. She also has no exploitable weakness โ no equivalent of Thor losing Mjolnir.
Thor wins by the thinnest margin through Mjolnir's versatility and the God-blast trump card. But Wonder Woman is the better fighter, and on any given day, her skill could overcome his power. This is one of the most evenly matched cross-publisher fights possible.
