Stardust is a comic book character created by Marvel Comics and is known to be one of the publisher's most powerful and mysterious characters. He is a cosmic being who has come to Earth to protect it from the threats it faces. Stardust has a number of supernatural powers, including the ability to fly, superhuman strength, the ability to manipulate cosmic energy, and the ability to travel through time and space. He is also immortal and virtually indestructible, making him a formidable foe for any villain who confronts him.

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.
