Question
In the movie The Old Guard, Andy/Andromache loses her invulnerability. What triggers this? Is it when they reach a certain age, or is it because Nile joined the immortal group?
Answer
It is not explained.
As far as I know, it doesn't happen in the original comics. In the movie, it just eventually happens, seemingly without a specific cause.
The group discloses that they are not actually immortal: their power to heal eventually stops without warning.
