VegetavsWonder Woman

Wonder Woman is one of DC's most powerful heroes. As a demigod daughter of Zeus, she has strength rivaling Superman's, centuries of combat training, and divine weapons including the Lasso of Truth and a sword that cuts atoms. She has fought Darkseid's forces, matched Superman in combat, and defeated the god of war Ares. In the DC universe, Diana is a top-tier powerhouse.

Vegeta in Ultra Ego form, however, operates at a power scale that exceeds most DC characters. Even base-form Saiyan Saga Vegeta could destroy planets with a casual blast. Ultra Ego Vegeta fights at universal-to-multiversal levels, grows stronger with every hit he takes, and has ki output that dwarfs planetary-level attacks. His Final Flash in the Cell Saga had enough power to destroy the solar system, and he's gotten exponentially stronger since then.

Wonder Woman's combat skill is arguably superior — she has centuries more training than Vegeta and her technical fighting ability is refined to an incredible degree. Her god-killer sword and Lasso of Truth are powerful divine artifacts. But combat skill becomes less relevant when the power gap is this enormous. Vegeta's ki blasts alone output more energy than Wonder Woman has faced from any opponent except the absolute highest tier of DC characters.

The one area where Wonder Woman might have an edge is her magical nature. Dragon Ball characters have been shown to be vulnerable to exotic abilities like magic, and Wonder Woman's divine weapons could theoretically bypass ki-based defenses. But Vegeta's raw speed and power likely prevent her from ever landing a clean hit.
