¿Who is stronger, Lobo or Buu?

Lobo is a powerful and dangerous character from the DC Universe, first appearing in the DC Comics series "Omega Men" in 1983. He is an intergalactic bounty hunter and assassin, and is one of the most feared and respected figures in the DC Universe. Lobo's story begins on the planet Czarnia, where he was born as the son of a scientist named Professor Velorkam. From a young age, Lobo displayed extraordinary strength and durability, and he quickly rose through the ranks to become one of the most feared and respected bounty hunters in the galaxy. As a result of his unique physiology, Lobo possesses a number of superhuman abilities, including strength, speed, agility, and durability. He is also immune to all forms of injury and disease, and is virtually indestructible. In addition to his physical powers, Lobo also has access to a wide range of advanced technology and weaponry, including his signature spacehog motorcycle and a number of powerful weapons, such as his regenerating chainsaw. Throughout his long and storied career, Lobo has clashed with many of the DC Universe's greatest heroes, including Superman, Batman, and the Green Lantern Corps. Despite their best efforts, these heroes have often struggled to defeat Lobo, making him one of the most formidable and dangerous villains in the DC Universe.

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.
