[Dragonball Z/Super] With proper Ki training could Mr Satan potentially be one of the greatest human level Z fighters?

Mr. Satan is, in all seriousness, one of the most powerful characters in Dragonball Z. It's tricky to see this because he's such a farce, but the whole series is comedy at its core, in what it has to say about people and how to live and the nature of the world. The fight in its truest form is always for joy as much as survival. 

Mr. Satan is basically Grandpa Gohan / Master Roshi, but for the whole world, instead of just one person or a small group of people. Yes, he has fighting abilities, but lots of people can have absurdly powerful fighting abilities and still be useless at combating the actual problems facing humanity. Mr. Satan, silly as he is, inspires people. And Toriyama values this a lot (after all, inspiring people with laughter joy and the desire to work together and improve themselves and the world and be happy is what Toriyama does a a storyteller).

It is not just a joke that it is Mr. Satan, not Goku or Vegeta, who inspires everyone to give their energy to the spirit bomb that destroys Buu; it's the moral of the whole Buu saga. Sometimes inspiring people really is more powerful than fighting them - this is, after all, what Goku does for Piccolo and Vegeta - not just beats them, but inspires them and believes in them, so that eventually they believe in him too, and in something better for themselves, the people they care about, and the world. 

And Mr. Satan inspiring Buu to give up killing people is probably the single bravest and most impressive thing anybody does in the whole story. Not even the spirit of the Grand Supreme Kai could do that. Mr. Satan is a vain buffoon who, just because he can inspire goodness and joy by his theatrics, is more powerful than the most powerful God.

It goes back to the most important thematic scene in Dragon Ball, which is the one where Master Roshi explains to Tenshinhan the difference between the Crane School and the Turtle School. You don't have to be unhappy. You don't have to hate life. You can be happy and love life and love other people and still be strong. 

You can be an abandoned weapon and save the world. You can be a walking joke and save the universe. 

Yeah, Mr. Satan could have been a great fighter if he'd trained with the Z Fighters. But he was so much more than that. 

He was the World Champion.
