Movie
Description
In the second Dragon Ball film, Sleeping Princess in Devil's Castle, the character known as Butler is a minor antagonist and a servant of the demon lord Lucifer. He is also referred to by the name Igor within the narrative. His primary function within the castle is to carry out a specific and grim duty for his master's plan.

Butler's most notable trait is his specialized knowledge, particularly concerning blood. He demonstrates an understanding of its properties while preparing for the ceremony to awaken the Sleeping Princess. His personality is not explored in depth, but his actions portray him as a loyal and obedient subordinate, diligently following Lucifer's orders without question. As a resident of the Devil's Castle, he is aligned with the forces of evil and serves a direct role in their scheme.

His main motivation is tied directly to his service. He is tasked with collecting blood from Bulma, who has been captured by Lucifer's forces. This blood is required for a ceremonial toast meant to celebrate the awakening of the Sleeping Princess and the subsequent destruction of the sun, an event that would usher in a reign of darkness. Butler is the one designated to perform this extraction.

In the story's climax, Butler corners Bulma with a giant syringe, intending to drain her blood. However, before he can complete his task, he is confronted by Yamcha. Proving to be a relatively weak demon, Butler is swiftly defeated by a single kick from Yamcha, ending his threat immediately. This encounter serves as a brief moment of peril for Bulma and a small heroic action for Yamcha, showcasing the dangers within the castle before the final battle with Lucifer.

His key relationship is with his master, the primary villain Lucifer, to whom he reports and for whom he carries out his orders. He also has a functional, antagonistic relationship with Bulma, viewing her as a source to be harvested rather than a captive to be negotiated with. He is not connected to the main heroes, Goku and Krillin, and is dealt with by Yamcha before any direct interaction with them can occur.

Butler does not undergo any significant development throughout the movie. He is a static obstacle designed to create a moment of tension and is quickly removed from the plot. His role is purely functional to the antagonist's ritual.

Regarding notable abilities, Butler does not possess any remarkable supernatural or martial arts skills. His physical strength is slightly above that of an ordinary human, as he is capable of wielding heavy equipment like a giant syringe. He also carries a hatchet, which he attempts to use as a weapon against Yamcha after his initial plan fails. Despite this equipment, he is overwhelmingly outmatched by even a low-level fighter like Yamcha, establishing him as a minor and insignificant threat in the overall conflict.
