* ''Manga/VampireHunterD'': The Sacred Ancestor, aka Dracula.

** All demons in the world can trace their lineage back to the original seven Primordial/Progenitor demons, who before they themselves received proper names went by [[EveryoneCallsHimBarkeep their colors]]: Red/Rouge (Guy Crimson), Black/Noir (Diablo), Green/Vert (Mizari/Misery), Blue/Bleu (Rhein/Rein), Purple/Violet (Ultima), White/Blanc (Testarossa), and Yellow/Jaune (Carrera). What lineage a demon's "color" aligns to influences their personality to something close to their progenitor. They're also the [[StrongerWithAge strongest of their kind by virtue of being some of the oldest beings in the world]]. Notably, Guy is the only one who truly fits the mold as he's not only the [[TheOlderImmortal oldest of the Primordials]], he's the only one who hasn't sworn himself to the service of another person (indeed, he was the one who named and is the master of Misery and Rein, who serve him loyally) and sees himself as someone destined to rule as one of the most powerful Demon Lords in the world. Diablo meanwhile technically roped in Ultima, Testarossa, and Carrera into working alongside him under [[TheHero Rimuru Tempest]], and unlike the other Primordials he was never interested in even creating many demon subordinates to lord over in the first place, which was just one of his many "eccentrics" by demon-kind's standards.

* ''Franchise/{{Nasuverse}}'': Crimson Moon can be considered the progenitor of [[OurVampiresAreDifferent True Ancestors and, through them, all vampires]]. While he didn't exactly spawn them, [[OverarchingVillain Gaia]] used him as a template for her purported defenders against humanity, which didn't go well, since all of them inherited Crimson Moon's BloodLust alongside an unfortunate quirk of Gaian elementals: going insane when they drink blood. It's easy to see how this went badly.

* ''Literature/TheLotusWar'': The Oni and other monstrosities out of the land of Yomi, they're the offspring of the goddess Izanami.

* *Ragadahn claims to be the father of dragons, a claim most true dragons consider heretical at best. Linnorms, on the other hand, generally consider him to be the first of their kind.

** The demon lord Kabiri names himself the progenitor of all ghouls and the first being to commit cannibalism. This is disputed by the [[OurGhoulsAreCreepier Leng ghouls]], who claim that Kabiri copied them, while he says they abandoned him. Evidence suggests the Leng ghouls are older.

* Myth/ClassicalMythology has Typhon and Echidna, the parents of ''all'' monsters.

** The so-called "Grey Court" (classic Dracula vampires) are, as their Marvel counterparts, descended from Varnae, an Atlantean experiment GoneHorriblyWrong[=/=]GoneHorriblyRight (depending on your point of view). The Red Court, meanwhile, is said to be descended from the Mayan bat god Camazotz.

* [[EldritchAbomination The Sleeper]] from ''Fanfic/TheDesertStorm'' series claims to be the oldest and most powerful of the [[WitchSpecies Dathomiri Nightsisters]], referring to itself as "the Witch from which all Witches descend".

* ''Literature/ParadiseLost'': While many of the demons are actual examples of FallenAngels, others are the spawn of Lucifer/Satan and his daughter Sin, making them Monster Progenitors.

** The [[ALoadOfBull Minotaur]] race is believed to [[DivineDate descend from the union]] between St. Alessia (the "Slave Queen" who led the Alessian [[SlaveLiberation revolt]] against their [[AbusivePrecursors Ayleid]] masters) and Morihaus, the [[OurAngelsAreDifferent Aedric demi-god]] "winged man-bull" sent by the [[OurGodsAreDifferent Divines]] to aid Alessia. [[EternalHero Pelinal Whitestrake]], Alessia's "champion" and Morihaus' divine "uncle," specifically warned Morihaus against this relationship, believing that they would "beget more monsters on this earth." (Which, if this is the true origin of Minotaurs, proved to be the case.) Their son, Belharza, was said to be the first Minotaur and became the second Emperor of the Alessian Empire following his mother's death.

* ''TabletopGame/{{Pathfinder}}'': Ragadahn claims to be the father of dragons, a claim most true dragons consider heretical at best. Linnorms, on the other hand, generally consider him to be the first of their kind.

* ''Manga/DemonSlayerKimetsuNoYaiba'': Muzan Kibutsuji, he's the original demon, created the other demons(in fact the only capable of creating other demons), though he states that he actually hated doing it, but had to in order to find either a demon that could withstand the sun or the main component in the elixir that made him a demon in the first place.

-->--'''Music/{{RZA}}''', ''Fatal''

* ''Film/CountYorga'' is this in both films being the main cause of vampirism. The first film implies he wasn't even bitten but turned himself in a vampire through occult magic. One of the reasons he moved to L.A from whatever European country he came from (implied to be Bulgaria) was to see if the curse could take effect in a modern day foreign country. Indeed, though it's now the 70s, the vampirism works as strong as ever as shown with the two brides he claims at the start and one we see slowly transform after he bites him. By the second movie (which has it's own continuity separate from the first) he's already turned five women into his brides at the start and has at least a dozen near film's end.

* ''Literature/SalemsLot'': Barlow is the cause of the vampires in the book. Having picked Salem's Lot because it's secluded and because the town holds so many dark secrets it practically attracted him like a moth to a flame.

-->--'''RZA''', ''Fatal''

{{Dracula}} is very often made into the Monster Progenitor of all vampires, as are [[BiblicalBadGuy Abrahamic baddies]] like {{Cain}} (see TheDescendantsOfCain) and Myth/{{Lilith}}.

* ''VideoGame/{{Pokemon}}'': Mew is said to have the DNA of every single pokemon within its own, leading many to theorize that it is the last common universal ancestor for all pokemon. Arceus, likewise is considered the creator of Sinnoh and possibly the entire known universe (including, one would imagine, the pokemon within it).

* ''LightNovel/ThatTimeIGotReincarnatedAsASlime'': All demons in the world can trace their lineage back to the original seven Primordial/Progenitor demons, who before they themselves received proper names went by [[EveryoneCallsHimBarkeep their colors]]: Red/Rouge (Guy Crimson), Black/Noir (Diablo), Green/Vert (Mizari/Misery), Blue/Bleu (Rhein/Rein), Purple/Violet (Ultima), White/Blanc (Testarossa), and Yellow/Jaune (Carrera). What lineage a demon's "color" aligns to influences their personality to something close to their progenitor. They're also the [[StrongerWithAge strongest of their kind by virtue of being some of the oldest beings in the world]]. Notably, Guy is the only one who truly fits the mold as he's not only the [[TheOlderImmortal oldest of the Primordials]], he's the only one who hasn't sworn himself to the service of another person (indeed, he was the one who named and is the master of Misery and Rein, who serve him loyally) and sees himself as someone destined to rule as one of the most powerful Demon Lords in the world. Diablo meanwhile technically roped in Ultima, Testarossa, and Carrera into working alongside him under [[TheHero Rimuru Tempest]], and unlike the other Primordials he was never interested in even creating many demon subordinates to lord over in the first place, which was just one of his many "eccentrics" by demon-kind's standards.
