Beelzebub (ベルゼブブ) is the main character in Akira Toriyama's 2000 one-shot manga, Sand Land. He is the Prince of Demons, and the son of the King of Demons Lucifer, who also makes an appearance in this manga.
Beelzebub is renowned as the "Prince of the Underworld," but generally referred to only as "Prince" by his fellow demons. He lives in Sand Land, a barren wasteland inhabited by humans and demons where the supply of water is controlled by a greedy human king. Beelzebub tries to live in relative harmony with the humans: although he regularly steals water from them, he only takes as much as he and his fellow demons need to survive. Simply out of boredom, Beelzebub and a wise demon called Thief join Sheriff Rao in his quest to find an elusive lake which will possibly meet the needs of the inhabitants of Sand Land. In search for the long-lost lake, the trio confronts the king's army several times and discovers the truth behind many mysteries. Beelzebub lends the old sheriff his enhanced sight and demonic strength to fight against the king's army and bring down the tyrannous human king.
- This character is named after Beelzebub, another name given to the devil in the New Testament, which itself derives from Baal Zebub (lit. "the god of flies" though it was originaly god of ALL THAT flies, not flies alone), the name of an ancient Phoenician idol.
