Mephistopheles, also known as Mephisto or Mephistopheles, is a demon featured in German folklore. He originally appeared in literature as the demon in the Faust legend and has since become a stock character appearing in other works of arts and popular culture.

In the legend, Faust makes a deal with the devil at the price of his soul, Mephistopheles acting as the devil's agent. Faust believes that he has summoned him, but Mephistopheles says that he came of his own accord, and that he serves Lucifer, and cannot do anything without his leave. Faust questions Mephistopheles about Lucifer and Hell, and tells him to speak to Lucifer and return.

Mephistopheles returns, and Faust signs a contract in his own blood: Mephistopheles will serve him for 24 years, at which point Lucifer will claim him, body and soul. Once the contract is signed, Faust asks for a wife, but Mephistopheles declines, saying marriage is "but a ceremonial toy"; he asks for books of knowledge, and Mephistopheles provides a single book.

Faust begins to waver and think about God, and is visited again by the Good and Bad Angels. Lucifer arrives to remind him of his contract, and entertains him with a show of the Seven Deadly Sins. Faust and Mephistopheles then travel Europe, eventually arriving in Rome, where they play tricks on the Pope.

Faust has been called to the court of the Holy Roman Emperor, where he and Mephistopheles conjure Alexander the Great and his paramour and give a knight cuckold's horns for being a heckler. In the one version, the emperor asks Faust to relent, and he does; but in another version a longer scene follows in which the knight and his friends attack Faust; all are given horns. In both versions, Faust then plays tricks on a horse dealer. Faust and Mephistopheles then put on a magic show for the Duke and Duchess of Vanholt.

When Faust's 24 years are nearly up, He conjures Helen of Troy for some students, and, when he starts to think of repenting again, renews his pledge to Lucifer and asks Mephistopheles for Helen as his lover. In the final scene, Faust admits to some scholars that he has bargained away his soul; despite their prayers, the devils come for him.
