Fallout: Are Ghouls Immortal?Fiction
In-universe lore. Claims are judged against the fiction's own canon, not the real world.
A Fallout ghoul can shrug off 270 years, regrow a severed arm, and bathe in radiation that would kill anything else - and not one has ever been shown dying of old age. Yet the franchise's own designers admit they never decided WHY, and the real clock on a ghoul isn't the body's: it's the brain quietly rotting toward feral.

Supports- What even created ghouls: pure radiation, or radiation plus the FEV virus?Fallout Bible 8 (Chris Avellone) analysis
- The Fallout Bible documents the split outright: 'Radiation according to Tim Cain, FEV + radiation according to Chris Taylor' - the two original designers disagreed.Fallout Bible 8 (Chris Avellone) analysis
- Fallout Bible 0 backed the FEV side: Vault 12's ghouls were exposed to BOTH radiation and FEV when shattered West-Tek tanks released the virus while radiation 'rotted away' their bodies.Fallout Bible 0 (Chris Avellone) primary

Supports- Are ghouls truly biologically immortal, or just extremely long-lived?Fallout Bible 8 (Chris Avellone) analysis
- Against that, the games depict 270-year-old ghouls with no senescence and radiation that perpetually heals them, so fans reasonably read the species as effectively deathless.Ghoul (Fallout) - Wikipedia summary

- New Vegas's elderly ghoul Raul tells the Courier that survive long enough and 'one day you'll get old and decrepit, like me' - implying ghouls still age and wear down.Raul Tejada dialogue (Fallout: New Vegas) primary
