The diablo saga!

Diablo is an ancient namekian. He is the younger brother of slug, and is now in his sixties.

Arrival on earth!
Diablo had heard of slug's death at the hands of the saiyan, goku. Angered by this, a fully fueled by hatred ancient namekian raced towards earth. He used instant transmission and supressed his energy to arrive undetected on the lookout. Once there, diablo tied up dende and mr. popo. Piccolo was released from hell, and arrived on the lookout. He was caught off guard and frozen by the ice beam of diablo.

Come forth, porunga!
Diablo had brung the namek balls to earth. He wished for immortality, the saiyans to lose super saiyan, and for the heroes of earth to be as weak as the saiyans. Goten and bulla sensed evil, and went to the lookout, to be immediately frozen by diablo. Upon sensing danger, trunks, uub, steven, and supreme kai appeared as well. Majin buu also came. They all were soundly defeated. Supreme kai was separated from kibito, due to the elder kai. Diablo beat them all. Eventually, after a great fight, diablo was sent through the sun. Somehow, goten transformed into a super saiyan and shot diablo to the sun, via a spirit kamehameha!
