In Dragon Ball Super, Mo Luo and Demon Buu both had the ability to devour. However, Buu's devouring ability was even stronger because he could completely devour his own energy and soul to make himself stronger. In comparison, although Mo Luo's devouring ability could also devour the energy and souls of other creatures, it had not reached the realm of completely devouring himself and others. Therefore, in terms of combat strength, Demon Dweller Buu's devouring ability was even more outstanding than Mo Luo's.
Well, it depends on different stages of the story. In certain scenarios, Gohan shows more power, but Buu is a tricky opponent with unique skills that make it hard to say for sure who's stronger overall.
Buu the Demonkin was a character in the Dragon Ball series, not in Dragon Ball Super or any other works. Buu the Demonkin first appeared in the fourth game of the Dragon Ball series, Dragon Ball Z: Buu. He was a very powerful villain with the ability to transform into both human and demon forms.
The starting point of the Dragon Ball Demon Man Buu manga was the fourth volume of the Dragon Ball series, Dragon Ball Z: Broly. The manga was released in Japan in 2015 as part of the Dragon Ball series.
In the DBZ manga, Kid Buu is indeed stronger than Super Buu. This is shown through their various battles and power displays. Kid Buu's raw and chaotic power gives him the edge over Super Buu.
Kai doesn't have a major role within Buu in the manga. It's more focused on the main characters' battles and developments.
Dragon Ball was a Japanese manga that told the story of Sun Wukong and the other characters fighting to save the Earth from the threat of aliens. Buu the Demon Man is a villain in the Dragon Ball. He is an alien with powerful strength and evil will, posing a huge threat to the peace of the earth. In Dragon Ball, Sun Wukong and the other characters had many fierce battles with Buu the Demonkin. The most famous one was their final battle with the help of Cyborgs No. 17 and No. 18. Therefore, the Dragon Ball Demon Fighter Buu was an important storyline in the Dragon Ball series and a classic scene in the works.
Overall, the manga version of Dragon Ball Super might handle Buu's story arcs with a bit more depth and complexity. For example, it could explore his background or motivations more thoroughly.
One possible scenario could be Satan trying to train Buu to become a 'good' fighter in the sense of human values. He might introduce Buu to things like sportsmanship, which would be really funny considering Buu's nature. Buu might initially be confused but then start to adapt in his own strange way.
