Hercule Satan, known as Mr. Satan in the original Japanese version of Dragon Ball Z, is the World Martial Arts Champion famed for his bravado and comedic antics. Despite lacking the superhuman powers of the Z Fighters, he is beloved by the public, credited with defeating major threats like Cell and Majin Buu (though this is untrue). He provides comic relief, but also shows courage and kindness, playing a key role in befriending Majin Buu and aiding in Earth's survival.
