Pure Evil villains who were once heroes, once fighting on the side of good but turned to villainy. When they've turned to villainy, these type of villains have shed all their redeeming qualities.

While it's undoubtedly true that when a character has committed heinous acts on their own accord that they can't be ever considered Pure Good, however, a Fallen Hero may have at one point followed the criteria of a Pure Good very well, later abandoning that with the worst possible outcome being a total 180 of the good criteria they once were that is Pure Evil at its finest. (e.g. Dr. James Sheridan)

For obvious reasons, these villains also count as Wholly Debased and Redemption Rejection.

Good examples are Sauron, Scar, Exar Kun, Pong Krell, The Batman Who Laughs, Maker, Zombie Giant-Man, Maestro, Nova Prime, The Plutonian, Tengu Shredder, Femto, Cobra Commander, God and Lucifer, The Entity, Light Yagami, Valak and Immortan Joe.

They are the opposite of Redeemed Villains.

Notes[]

Please note that a character must be a hero before turning evil.

• Morally neutral characters (a la "average joes") or characters initially uninvolved with any side of the conflict do not count (e.g. Lots-o'-Huggin' Bear, Syndrome, Freddy Krueger, Andy Evans, Randall Boggs, William Afton and Porky Minch), they should go under From Nobody to Nightmare instead.
• False heroes, if they never were good, they do not count either (e.g. Emperor Palpatine, Mysterio, Lots-o'-Huggin' Bear, King Runeard, Judge Claude Frollo, Shiranami, Sister Sisto, Leo Kasper, Mari (Hands), Piella Bakewell and Jill Roberts). They should go under Faux Affably Evil, Liars, Cheaters, Tricksters, Hypocrites, Hidden Pure Evils, Delusional, Traitors, Master Manipulators, Con Artists, Spies and/or Contradictory instead. However, some false heroes in the present story can still be true heroes prior to the story (e.g. Commander Rourke, Sentinel Prime, Peter Pettigrew and Pong Krell).
• Normal law enforcement, military, firefighters, guards, paramedics, agents, wardens, businesspeople, executives, managers, workers, doctors, scientists, teachers, mayors, politicians, principals, students, student councils, club presidents, cheerleaders and etc who became evil do not count (e.g. Bob Barnes, Samuel Norton, Lord Cutler Beckett, Ragyo Kiryuin, William Afton, Cecil Creepler, Alex and Frank Tenpenny), they should go under Corrupt Officials, Kids, Teenagers, and/or Juvenile Delinquents, instead, unless they are reported to have done something truly heroic (e.g. Cobra Commander and Femto).
• Villains who simply lose all of their redeeming qualities do not count (e.g. Dio Brando, most versions of The Joker, The Ink Demon, William Afton, Peter Pan, Vilgax, Frank Underwood, The Dark Lord, Alan Yates and King Boo), they should go under Wholly Debased instead, unless they were actually heroes in the past (e.g. Khan Maykr, Immortan Joe and Light Yagami).
• Servants/Pawns, villains who served on the hero's side but other than that have never done anything heroic or good do not count either (e.g. Dick Hardly, Dimentio, and Micah Bell). They should go under Servant of a Hero instead, unless they actually did genuine heroism.
• Nice people, villains who were simply nice people before they became villains (e.g Isaac Ray Peram Westcott, Stu Macher, William Afton, Randall Boggs, The Ink Demon, Syndrome and Lots-o'-Huggin' Bear) also do not count if they did nothing truly heroic before they actually became villains. They should go under From Nobody to Nightmare and Wholly Debased instead.
• Brainwashed or Forced into it, if a villain was forced into it by circumstance or were brainwashed into becoming heroes (e.g Yuuki Terumi), they also do not qualify.
• Famous people, villains that simply had a good reputation do not count (e.g. Lionel Starkweather and Kray Foresight). They should go under Charismatic, Faux Affably Evil‏ and/or From Nobody to Nightmare instead, unless their good reputation was earned from heroism in the past (e.g. King Magnifico).
• Protagonists, villains who are simply the main character in the story do not count either (e.g. Frank Underwood and Patrick Bateman), unless they have actually done anything heroic in the past (e.g. Light Yagami and The Plutonian). They should go under Protagonists instead.
