Why didn't the author of Dragon Ball Super allow Buu the Demonkin to participate in the Strength Conference?
In Dragon Ball Super, the Demon Buu was a very powerful villain with combat power comparable to the Super Blue Warrior. However, the author did not let Buu participate in the power conference because he wanted to show Buu's different side and show his confrontation with other characters. The participants of the Strength Contest were all trained and strengthened warriors. Their combat strength was very high. However, Buu the Demonkin was not a trained and strengthened character. His combat power was far from that of ordinary people, so he could not participate in the Strength Conference. In addition, there are some contradictions and problems in the story. His existence itself is a kind of contradiction, so the author does not want him to participate in the power conference, but hopes to show his existence and influence through other means.
