Lucifer

Lucifer appears in the early Dragon Ball movie Sleeping Princess in Devil's Castle, where Goku and Krillin are sent by Master Roshi to rescue what they believe is a kidnapped princess. Upon arriving at Devil's Castle, they discover that the Sleeping Princess is not a person but a giant jewel that Lucifer has been using to gather energy.

As a demon with vampiric qualities, Lucifer possesses supernatural abilities including flight, superhuman strength, and the ability to command lesser demons. He is refined and aristocratic in manner, presenting himself as a gentleman even while carrying out villainous schemes. His ultimate plan involves using the Sleeping Princess to fire a giant laser at the sun, which would eliminate sunlight and allow demons to roam the Earth freely.

Goku ultimately defeats Lucifer by deflecting the laser beam back at him using a Kamehameha wave. The demon lord and his castle are destroyed in the resulting explosion. Lucifer remains a curiosity in Dragon Ball history as one of the few supernatural, non-martial-arts villains in the franchise, predating the series' later shift toward increasingly powerful alien and divine threats.
