A Chat with Satan

"Everyone who wants to grow up, sooner or later sits down and has a chat with Satan. Or they never grow up."

- Amos Maple, Down From Ten

Before the hero can achieve his destiny, he has to face himself and defeat the darkness in his own heart. Because Only the Worthy May Pass, someone has to put the hero to the test and make sure that he has the character necessary to see things through.

Enter Satan. Sometimes this is the literal Guy With The Horns and Pitchfork; sometimes it's just the character's Shadow Archetype, or the Old Master. Regardless, it's the character who knows the hero's dark side better than the hero himself—and is determined to make sure the hero sees it, as well.

If the hero fails this Secret Test of Character, expect things to end badly for him.

Essentially, when a supporting character talks to the hero to reveal What You Are in the Dark. Differs from a Deal with the Devil in that the Satan-figure is primarily concerned with exposing the hero's true nature (and can sometimes be akin to a Trickster Mentor, actively trying to improve the hero by getting them to see and reject their darker side); if the hero does not succumb to temptation, it doesn't mean that the tempter has failed in his mission. A type of Threshold Guardians. If the character playing "Satan" really does want to corrupt the hero, then they're The Corrupter.

Anime & Manga

 * Naruto plays this very straight in one example, except for one minor twist; Naruto knows his dark side even better than the "dark side" itself, and actually embraces it and comforts it. In a way, his dark side was something that he mostly outgrew as he grew up.
 * In Mahou Sensei Negima, Evangeline goes through this with Negi. She tells him he can either face down his true dark nature and overcome it, bending it to his will, or he can become a raging immortal demon. She thinks the latter is kind of cool.
 * In Heartcatch Pretty Cure, Tsubomi and co must pass the test against their respective Shadow Archetype to obtain their Super Silhouette. They viciously point out the Cures' weaknesses and manage to be pretty sinister for a kid's show while doing so.

Film

The first time with the Palantír to taunt the Dark Lord with the fact that he now has the Sword of Elendil to which Sauron responds by showing him an image of Arwen.

As a result, he loses a hand and has to be rescued by Leia, who has escaped through other means... thanks to R2-D2, who had come with Luke from Dagobah.

 * In Matthew 4, Mark 1 and Luke 4, Jesus goes into the wilderness and is tempted by Satan. The devil presents him with three successive challenges, appealing to his appetite (turn this stone into bread), his vanity (jump off the temple so people will see God catch you), and his sense of his own destiny (worship me and I will give you all the kingdoms of the world). Jesus refuses each of the tests, thus proving that he is worthy to begin his ministry.
 * Ditto in Buddhism—the last barrier to enlightenment that Siddhartha Gautama faced was Mara, the Anthropomorphic Personification of temptation.

Last seen as a giant penis-chariot in Persona 4.

Theatre

 * The verse drama Murder in the Cathedral by T. S. Eliot focuses on Archbishop Thomas Becket in the days leading up to his murder. In the first act, he is visited by "tempters" who plead with him to give up his feud with the King of England. The first tempts him with hedonistic pleasures, the second with a restoration of his former authority, the third with political power. He rejects them all, but the fourth tempter surprises Becket by asking him to seek out martyrdom, and be glorified as a saint long after his death. Becket has to reconcile his moral stance with his own selfish desire to be justified in the hereafter. (In most productions, the fourth tempter is presented as being separate, more enticing than the first three, and possibly the Devil in disguise.)
