The last villain of the Dragonball Z series. This is
Majin Buu's form before he absorbs any of the Supreme Kais, and is even far stronger than
Super Buu (
Gotenks, Piccolo, and Gohan). In other words, this is his original form that Bibidi first created. Kid Buu has no conscience, he seeks only to destroy and fight strong opponent, he's not very bright either.
Statistically, in terms of
kill count, Kid
Buu has the highest body count in the Dragon Ball universe, having destroyed several hundred planets worth of people. In total, Kid Buu generates an excessively high body count exceeding the trillions. In the series, Buu is by far the oldest villain, as Bibidi died long before he did. He was sealed inside a cocoon for a very long time as well, about a million years according to
Babidi, though this just may be an estimate or exaggeration.
