¿Who is stronger, Buu or Gogeta?

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.

Gogeta is a prominent fusion character in the "Dragon Ball" series, resulting from the union of Goku and Vegeta through the Fusion Dance. This fusion combines the strengths and abilities of both warriors, creating a formidable fighter.

Gogeta's debut occurs in the 1995 film "Dragon Ball Z: Fusion Reborn," where he confronts the villain Janemba. In this appearance, he showcases the Super Saiyan form. Later, in "Dragon Ball GT," Gogeta achieves the Super Saiyan 4 transformation during the battle against Omega Shenron, displaying immense power and a confident demeanor.

In "Dragon Ball Super: Broly," Gogeta returns, this time attaining the Super Saiyan Blue form to combat the formidable Saiyan, Broly. This portrayal highlights his strategic prowess and combat skills, solidifying his status as one of the most powerful characters in the series.

Gogeta's techniques include the "Big Bang Kamehameha," a combination of Goku's Kamehameha and Vegeta's Big Bang Attack, and the "Stardust Breaker," an energy attack designed to purify evil. His fusion, achieved through the Fusion Dance, is time-limited, typically lasting 30 minutes under normal conditions.
