Hm, sounds like a pretty big weakness for prime to exploit
[The Darkest Knight created whole new stories that would never have been allowed to become real](

[These stories are metafictional, presented directly to the reader as horrifying new narratives. "
are you ready to turn that page dear reader, the horrors out there are ready for you, they're out there -- Clean and Terrifying. Flesh made pure by metal".
[Superboy Prime who is metafictional for being representation of reader in the representation of our real world, saying that the stories TDK made are the imaginary stories reject after punching him and changing him (a story that would never have been allowed to be real) which is a story he never read as a reader before, and he also change that story.](

There is author's statement saying
everyone on earth prime is able to affect reality like the writer which is plot manipulation because earth prime described as a
metafiction world. Also in infinite crisis when Alexander luthor of earth 3 looking for earth prime,
he performed a 4th wall feat similiar to Thought Robot in Final Crisis Superman Beyond #2, that's why when superboy prime back to earth prime he got
erased from comic or story, even there is a statement by narrator that
earth prime is our world the reader, and
superboy prime said realities is a comic page (
also here). Superboy Prime also stated that even if all the heroes died,
the stories would be rebooted and bring them back to life,
Because he has read many comics, he understands that characters such as Superman have died numerous times, yet never truly remain dead, since the stories themselves always restore them. In Earth Prime there is a DC Comics Tower where there is Julie Schwartz (Script editor), Cary Bates & Elliot (Both this are writer) they are representations of real people btw, you can search their names. And this is the ability of writer, Julie(editor)talks about :
Cary Bates was imagining the plot for the next issue and it really happened in reality. "I
started dreaming up a plot for my next flash yarn".
He chose Trickster as the villain and it actually happened in reality.
He did it all just with his mind and happened.
that's why
Superboy Prime changed Imaginary Stories Reject after he hit it. The reason he said he was a imaginary stories reject because it was a story made by Darkest Knight with the crisis energy which is
a stories that never would have been allowed to be real before, same description with stories in Lucien Library
which is an impossible story to happen and made from horror of human heart(
Impossible Stories destined to only happen in nightmare)(
Impossible Volume) &
Crisis Energy is explained to be born from the bad side of humans (we are the batteries for the crisis energy and its opposite) such as greed, selfishness, predation & human desire to be big. This suggests that Crisis Energy is the source of the stories within Lucien's Library, which explains why The Darkest Knight can made them into reality & affecting the stories read by the readers by giving them a
new and terrifying narratives, and
Prime able to change that stories.
