Lucifer

Lucifer was a demon with vampirish tendencies. Living in the Devils Castle in the Devils Hand mountain range he plotted to throw the world into eternal darkness and rule an Earth full of monsters. His exact age was unknown but he hints that he is at least five thousand years old. He led an army of monsters and undead that were completely loyal to him including Ghastel a crimson demon who was a powerful warrior and the hunchbacked Servant also known as the Butler or Igor. Despite being ancient Lucifer had kept up with the times and was quite modern his castle contained much computer equipment a laser cannon and a television this last is blackandwhite though it may be a stylistic choice. He possessed the Sleeping Princess a massive jewel that can channel tremendous energies when bathed in the light of the full moon. Lucifer had done this for thousands of years every moon increasing the gems power. Lucifer had two forms though the change seemed more visual than anything else. He first appears as a very handsome man almost a bishonen with large red irises dark blue skin and a hair style rather similar to Gokus though without the widows peak. But when he wished to intimidate or fight his irises shrank away to almost nothing leaving him with pinpoint pupils. He grew long fangs and his face became noticeably less soft. He dressed rather formally complete with bowtie and a large necklace. During the daytime he wore sunglasses. He was rather powerful able to dodge or deflect a young Gokus blows effortlessly. He had a strong attack of his own a scintillating scarlet sphere of energy that he could create and throw repeatedly. Lucifers master plan was to wait until the Sleeping Princess has absorbed enough energy expose it to one final full moon and use the resulting power to fuel a giant laser cannon which will destroy the sun. Then he will lead the planets undead in the new world of eternal darkness. On the very eve of his plans fulfillment his castle was crashed by Goku Krillin Yamcha Bulma Puar and Oolong. Separating Bulma from the others he was able to charm her into being the guest of honor at the nights ceremony. What Bulma doesnt realize until its too late is that this consists of her blood being drained from her to be used as drinks when the monsters toast Lucifers success. Before this can happen the others arrive as well as Launch there to steal the Sleeping Princess. His army was able to subjugate them all and imprison them in a large wall of rock. He takes Bulma to prepare to drain her blood and reveals his plan to her. Goku looks at the full moon becomes a Great Ape and destroys the wall of rock. The others manage to remove his tail and together they assault the laser cannon chamber. However they are no match for Lucifers power and during the battle he triggered the laser cannon to destroy the sun. Bulma screamed out to Goku what it was about to do and he blasted the cannon with a Kamehameha. This did not destroy the cannon but knocked it off its foundation and pointed straight at Lucifer. The cannon fired right as he looked down the barrel and the massive energy wave killed him. Source: Dragon Ball Wiki
