When Majin Buu is first introduced, he is a largely uncontrollable monster created by the evil sorcerer Bibidi and imprisoned for millennia in a sealed containment pod hidden on Earth. However, as game-changing as this ability is, Buu has rarely used it after joining the heroes, even as he continued to appear in the sequel series Dragon Ball Super. One of the most overlooked and miraculous abilities seen over the course of Dragon Ball Z came from Majin Buu, who revealed himself capable of healing to the point where he could resurrect the recently dead and even restore the sight of the blind.
Many of Dragon Ball's fan-favorite Z Fighters are capable of incredible abilities in addition to their awesome prowess as warriors tasked with defending the entire multiverse from evil.
