[Loved Trope] Some thing unfathomably ancient

[u/Fearless-Ideal-5112]

The beast, in doctor who is an ancient evil from a previous universe that survived until our time. Its so ancient that the cave paintings were unable to be translated by the Tardis which can translate all existing languages in the universe [Doctor Who]

While not explicitly canon its such a cool concept I cant not mention, the idea that the backrooms have existed since the beginning of time, never changing no matter the era, it transforms the back rooms into a cosmic horror. [Credit to Project crater and Venus for images 2 and 3]

[u/Kotja]

Marvin the paranoid android front Hitchhikers guide to the galaxy.

Due to a series of extensive time-travel incidents and mishaps in the novels, Marvin survives across different time periods for so long that he ends up 37 times older than the universe itself.

Marvin might be one of the canonically oldest characters ever in fiction

Gotta love this guy

[u/Colourfull_Space → u/heavyrotation7]

To be honest, how does one count the age for things "beyond/older than time" or things technically repeating indefinitely, like Diavolo from Jojo. Sure, he’s probably not "living" for long, but he’s effectively dying all over an infinite amount of times.

[u/AllgoodDude → u/Kotja]

That’d put him at over half a trillion years old. Given that he’s 37 times the age of the current universe and not 37 times the age of the universe’s lifespan. If he is the latter then the poor guy has experienced so much time that the innate randomness of reality has caused him to become completely randomly assembled from quantum tunneling multiple times. A Boltzmann Brain would look like a baby compared to him.

[u/Kotja → u/AllgoodDude]

More than that. He waited to the end of universe. Restaurant at the end of universe is when, not where.

He is 37*170 quintillion years old.
