Mr.Satan Character Facts

During the Dragon Ball Z time period, Mr. Satan is the reigning World Martial Arts Champion, a title won fairly by beating other normal earthlings in a time when Goku and other powerful fighters were battling on Namek and later against the Androids. During this time, Mr. Satan became rich and famous, but also an egomaniac. He boasted endlessly on television about his strength, and that he was the "best fighter in the world." In the eyes of characters who know otherwise, he is considered to be a showboating blowhard. When the Z Fighters arrived on the scene starting with the Cell Games, he started a pattern of claiming them to be his disciples, which, while preserving his status and self-serving ego, has produced good results in the past. 
In spite of showing many signs of greed and cowardice, Mr. Satan is still a fundamentally honorable, decent, sensitive and kind-hearted man. He genuinely cares about protecting the innocent and fighting for justice to the best of his abilities, and is prone to violent and righteous anger when faced with the abuse of helpless innocents by villains. He shows moments of great courage when his family and friends are threatened by evil. Mr. Satan's true colors are foreshadowed when he risks his life to get Android 16's head near Gohan, which leads to Gohan's transformation to Super Saiyan 2. In the Majin Buu Saga, Mr. Satan is revealed to be a fundamentally good man as opposed to the arrogant showboat persona he exhibits, and his bravery and kindness towards the good Majin Buu play a major role in Kid Buu's defeat at the end of the Kid Buu Saga. Prominently, he has saved the lives of Bee, Goku, and even Majin Buu.
