Endwalker's plot is loosely based on Arnold Schwarzenegger's Terminator (Spoilers)

[kpxmanifesto]

Its called the Frankenstein Complex, its a standard writing theme and has been for close to 70 years, starting with Frankenstein, going along to films like Colossus the Forbin Project, Gog and a host of others.
Meteion wasnt part of that btw, the writing themes are far more complex.

I wouldn't necessarily exclude Meteion from the Frankenstein Complex. Yeah, she's a biological creation as opposed to a mechanical one which is what the Frankenstein Complex usually refers to, but I'd still say Meteion's character represents that idea quite well because she is a creation who is a danger to the creator.
