Vegeta's universal-level power in Ultra Ego dwarfs even the mightiest Norse god's continental-scale feats.
Whether we're talking mythological Thor or God of War Thor, Vegeta outscales him by orders of magnitude. Dragon Ball's power scaling reached planetary levels in the Saiyan Saga โ the very saga where Vegeta first appeared. By the current arcs, Vegeta in Ultra Ego form is fighting beings that threaten universal and multiversal structures.
Mythological Thor is powerful โ he fights the World Serpent at Ragnarok, his hammer Mjolnir can level mountains, and he's one of the strongest beings in Norse cosmology. God of War Thor is similarly impressive, having killed all the giants and cracked the World Tree. But these are fundamentally planetary-level feats at their maximum.
Vegeta's Final Flash in the Cell Saga was planet-busting and that was roughly 1% of his current power. Ultra Ego Vegeta fights Gas and Granolah โ beings whose power dwarfs planets. His Hakai technique can erase matter at a fundamental level, something that doesn't just damage opponents but removes them from existence. Even without Ultra Ego, base Vegeta post-Tournament of Power is casually star-level.
Thor's best chance would be if Mjolnir has some unique hax property โ like being able to damage anyone regardless of power level. In some mythological interpretations, divine weapons bypass conventional durability. But Dragon Ball characters have resisted similar hax from beings far above Thor's tier. The power gap is simply too large.
Vegeta in Ultra Ego form fights at universal scales, and his Hakai technique can erase matter from existence. His Final Flash was planet-busting in the Cell Saga, and he's grown exponentially since then. Ultra Ego gets stronger with every hit he takes, making him a nightmare in extended combat. Vegeta's speed surpassed light back in the Namek Saga โ Thor cannot tag him.
Thor wields Mjolnir, a divine weapon that may bypass conventional durability scaling, and his control over lightning and storms gives him ranged options. He killed all the giants of Jotunheim and his strikes crack the World Tree itself. As a god, Thor may have resistances to ki-based attacks that don't exist in normal physics. His mythological status also grants him narrative power that pure scaling can't capture.
Vegeta wins decisively based on Dragon Ball's power scaling operating at universal levels while Norse mythology operates at continental-to-planetary levels. Thor is one of the most powerful beings in his mythology, but the gap between mythological gods and Dragon Ball characters became insurmountable long ago.
