¿Who is stronger, Buu or Vegeta?

Majin Buu is a pivotal antagonist in the "Dragon Ball" series, introduced during the "Majin Buu Saga" of "Dragon Ball Z." Created by the dark wizard Bibidi, Buu is an ancient entity with immense power and a malleable, pink physique. Throughout the series, Buu undergoes several transformations, each altering his personality and power levels, including Innocent Buu, Evil Buu, Super Buu, and Kid Buu. His abilities are vast and versatile, encompassing regeneration, absorption, and transmutation, such as turning adversaries into sweets. Despite his initial role as a villain, aspects of Buu's character, particularly in his Innocent form, display a capacity for change and even benevolence. This complexity adds depth to his character, making him one of the most memorable antagonists in the "Dragon Ball" universe.

Vegeta, the prince of the Saiyan race, is one of the most powerful characters in Dragon Ball. Initially a ruthless antagonist, his character evolves as he becomes a hero and protector of Earth. His strength is extraordinary, constantly growing after each battle, especially after transforming into Super Saiyan. Vegeta’s power escalates with forms like Super Saiyan 2 and Super Saiyan Blue, which combine godly power with his Saiyan heritage. His iconic moves, such as the Final Flash and Galick Gun, demonstrate his devastating combat skills. Beyond physical strength, his mental resilience and pride drive him to continually surpass his limits, making him one of the strongest warriors in the universe.
