Okay hun. Let's just act like we don't know there aren't many important characters in Kalos who aren't related to other important characters in other regions.
I think the Eternal Flower is the Philosophers Stone in Pokemon. Since AZOTH is a term from alchemy, it got me thinking to it. Since the Philosophers stone is said to grant immortality.
The Ultimate Weapon was used to bring back ha Pokemon, and it literally looks like The Eternal Flower. AZ, being exposed to it was given immortality.
It's never said how the machine was built but I believe AZ discovered the Eternal Flower as the Elixer Of Life, or in Alchemy words, AZOTH.
Uhm y'all need to quit trying it with Meganium. Queen isnt bothered by yall, especially since i see that some of y'all stan for the walking bucket of KFC
