Someone comes along and preaches a message about how they're going to make everyone's lives better. People will flock to them out of hope, or because they see an opportunity to increase their own power by aligning with the prophet. If they don't already have it, this figure will request assistance—physically, monetarily, or in some other way—so that their goals can be achieved. If the universe has a chosen one prophecy, this individual will likely claim they're The Chosen One.
But in one way or another, this figure is deceiving their followers. Their true goals are different from what they preach, and they are inherently selfish goals. Money, power, revenge, lust, a combination of the aforementioned reasons—the False Prophet's true motives could be any of those or something else entirely.
Subtrope (and a basic form) of Hypocrite. See also Scam Religion. Compare Dark Messiah for another savior figure that uses unethical tactics, but may actually be genuine in their intentions unlike a False Prophet. Compare Not-So-Well-Intentioned Extremist. Sister trope to Phony Psychic.
It goes without saying this is No Real Life Examples, Please!.
Beware of spoilers.
- Berserk: Griffith, the main antagonist for a majority of Berserk's run. After betraying the band of the hawk in exchange for power and a position among the god hand, Griffith re-enters the human realm and poses as a savior for humanity who would "vanquish the shadow that blots out the sun" when he is actually a harbinger of death and destruction. His image as humanity's savior is mostly based on (a) a premonition seen by people throughout midland and (b) backing from the holy see, Berserk's equivalent of the catholic faith.
- Fullmetal Alchemist: Father Cornello, the prophet of the religion worshiping the Sun God Leto in the village of Leor at the start of the manga and BOTH anime series, turns out to be nothing more than a con-man.

- Marvel Cinematic Universe: Thanos claims that he wants to kill half of all life in the universe so that the other half can will be saved from extinction by having more resources to consume. Joe Russo says in the DVD Commentary that the real reason he's committing genocide is to prove to himself that his rejected solution to save his species—killing half of them—would have worked. This is also why Thanos doesn't use benevolent methods to prevent extinction, like creating even more resources, granting immortality, or making a cure for every disease that's ever existed.
- Revenge of the Sith: Palpatine, a Dark Lord of the Sith religious order, lies to Anakin Skywalker about being able to cheat death so the latter will become his apprentice out of desperation to save his wife and unborn child.

- Mr. Ricco: Black militant Frankie Steele may once have had genuine ideals, like black people owning their own neighborhoods, but once he started getting media attention and government funding for his projects, he embezzled most of the money, leaving almost none of it for the people he was supposed to be helping. He strung along local blacks until almost everyone got sick of him, including the media, but he still has a small handful of followers.

He uses promises of deliverance to convince magic-users who are living in the human world to work against their own best interest and find the Weaveworld for him. As always with Shadwell, caveat emptor is in effect, and the best his marks can hope for is disappointment.
- The Treatise of the Three Impostors (Latin: De Tribus Impostoribus) was a long-rumored book denying all three Abrahamic religions: Christianity, Judaism, and Islam, with the "impostors" of the title being Jesus, Moses, and Muhammad. Hearsay concerning such a book surfaced by the 13th century and circulated through the 17th century. Authorship of the hoax book was variously ascribed to Jewish and Muslim writers.

- The Bible contains several denouncements of false prophets, especially towards the end of the Old Testament when Israel and Judah turn away from God and ignore the warnings that he's about to send them into exile. * Jesus also warns his followers about false prophets more than once, in one case naming another trope in the process. He gives particular warnings about anyone claiming to be his Second Coming, essentially saying that it'll be blatantly obvious to everyone when it really happens and in the meantime anyone making such claims is a false prophet.
- Warhammer 40,000:
- Several organizations preaching a slightly different version of the Imperial creed turned out to be genestealer cults preparing the planet for Tyranid invasion. Chaos cults tend to act similarly, at first out of a genuine desire for social reform in some cases.

Not too far away, you'll find a Gigglegibber who claims to be "Bristlebane's Profit", hoping to find an adventurer dumb enough to not notice the obviously fake altar. The Gigglegibbers are ultimately harmless in comparison to more aggressive goblin tribes, but their lack of intelligence makes them rather amusing.
- Fire Emblem: Three Houses: Archbishop Rhea tells Byleth to sit on a throne in the Holy Tomb to receive a divine revelation from the goddess, Sothis.

- Grandia II: Pope Zera Innocentus is the leader of the Church of Granas, and viewed by many to be the wisest and most powerful leader the church has had. With monsters on the rise and apparent curses appearing across the land, the people have turned to him to lead them lit of these dark times. In point of fact, Pope Zera and his subordinates are the one causing the curses and monsters because he knows his god Granas is dead, and he wants to revive, then later become, Valmar because humanity needs a god to serve. What keeps the Church of Granas from being a Scam Religion is that only Zera and his inner circle are aware of the spoiled information.

- Thaos ix Arkannon from Pillars of Eternity is a complex case. He is legitimately the High Priest of one of the settings' gods, Woedica, however, the gods themselves are exposed at the end of the game as artificial constructs, created by ancient soul-smiths as means of ideological and moral control over the peoples of the world. What's more, said soul-smiths were led by one of Thaos' previous incarnations, whose memories and identity he has inherited. However, because the gods' artificiality is all but forgotten in modern times, the only time someone actually refers to Thaos as a false prophet is in a flashback of when his past incarnation's former disciple Iovara call him out on it.
