"Why 6 seconds and not... 2571241 Planck time Units?" is in its inception a designer intent question. Why did the designer choose this time length and not any other arbitrary measurement can only be answered by the designer. And because of that, it is a speculation for everybody else unless the game itself defines WHY it chooses that unit. Some ...
“Primarily opinion-based” is the wrong close reason, but the question should still be closed, in my opinion. Designer-intent questions have been ruled off-topic here, and that’s inevitably what this question is.
It might be savageable if you reworked it to emphasize more the history as the thing you want to know—maybe asking about context, e.g. did D&D ...

Wants a BBEG for level 1 players
Wants to know how to go about making one
The answers that came in were some frame challenges, but some also did directly answer the above question ...

Is there a kind of damage or effect similar to "Brilliant Energy" weapons from 3.5e?
What race is most similar to a cat?
Is there ...
I don't think this is really a homebrewing question at this point
If we're talking about the most recent edit, which asks about what published monster best matches the one from the novel, then it's not really a homebrewing question.
If it's a monster ID question then the content could be a lot more focused-- we really need mechanical details and not fluff, ...
I do not think so
We typically don't allow homebrew this for me.
While we can review homebrew, we really don't support idea generation. And asking us to homebrew something is the equivalent of an idea generation. Those types of questions do much better in a forum or chat or somewhere else.
I know I am likely to be the minority voice here, but for the sake of future reference, I have decided to add this answer, so there is at least one counter argument. Let me start by saying that I respect the never-guess-the-system policy. However, I believe that policy cannot apply here, as there is nothing to guess.
