¿Who is stronger, Thanos or Vegito?

Thanos is a powerful and malevolent character from the Marvel Universe, first appearing in the Marvel Comics series "The Invincible Iron Man" in 1973. He is a powerful alien warlord from the planet Titan, and is one of the greatest threats faced by the Marvel Universe. Thanos' story begins on the planet Titan, where he was born as the son of Eternals A'Lars and Sui-San. From a young age, Thanos was obsessed with death and the pursuit of power, and he quickly rose through the ranks to become one of the most feared and respected figures in the Marvel Universe. As a result of his Eternal heritage, Thanos possesses a number of superhuman abilities, including strength, speed, agility, durability, and regenerative powers. He also has access to advanced technology, including a suit of armor that enhances his physical abilities and a number of powerful weapons, such as the Infinity Gauntlet. The Infinity Gauntlet is a powerful artifact that allows Thanos to manipulate time, space, and reality itself. With it, he is able to erase entire galaxies from existence, and has even been able to defeat some of the most powerful beings in the Marvel Universe. Throughout his long and storied career, Thanos has clashed with many of the Marvel Universe's greatest heroes, including the Avengers, the Guardians of the Galaxy, and the X-Men. Despite their best efforts, these heroes have often struggled to defeat Thanos, making him one of the most formidable and dangerous villains in the Marvel Universe.

Vegito is a prominent fusion character in the "Dragon Ball" series, resulting from the Potara earring fusion of Goku and Vegeta. This fusion combines their strengths, resulting in a warrior of exceptional power and skill. Vegito first appears during the "Majin Buu Saga" in "Dragon Ball Z," confronting Super Buu to rescue absorbed allies. In "Dragon Ball Super," Vegito reemerges as Vegito Blue, utilizing the Super Saiyan Blue transformation to battle the fused antagonist, Zamasu. His abilities include the Final Kamehameha, a fusion of Goku's Kamehameha and Vegeta's Final Flash, and the Spirit Sword, an energy blade technique. Vegito's fusion, achieved through the Potara earrings, was initially believed to be permanent; however, it is later revealed to last one hour for non-deity beings. Throughout the series, Vegito exemplifies the combined might and strategic prowess of Goku and Vegeta, making him a formidable force against powerful adversaries.
