[Pokémon ZA] What is the “3000-year-old weapon” that lies underground in Miare City? Considering the relationship between the story of AZ and Zygarde

Meare City, the setting of “Pokémon LEGENDS Z-A”.
At first glance, it appears to be a story of glamorous “urban redevelopment,” but behind the scenes lies the “dark history” unique to the Kalos region.
The “war 3000 years ago” and “final weapon” told in the original “Pokémon X/Y”.
We will take a deep look at how these are related to the story of this work.

Meaning of “Z” and “A”

It is thought that the “Z” in the title means Zygarde, and the “A” means AZ (Azet) or “Beginning (Alpha)”.
Humanity is digging underground in the name of urban redevelopment.
However, deep underground lies “Zygarde”, the guardian of the ecosystem.
When it is determined that the prosperity (redevelopment) of humanity will destroy the ecosystem, Zygarde will stand in the way as an enemy of humanity.

A man named AZ

3000 years ago, King AZ sacrificed the lives of many Pokémon to activate the ultimate weapon in order to bring his beloved Flaette back to life.
He became immortal and continues to wander until the present day.
There is some debate as to whether this work “Z-A” is a story of the past or the future, but either way, there is no doubt that AZ himself will appear and the story of his redemption will be depicted.

Getting closer to the origins of Mega Evolution

In the history of Kalos, it is said that Mega Evolution was born from a “stone bathed in the light of the final weapon.”
In other words, the energy source of Mega Evolution is “Pokémon’s biological energy” itself.
How should we handle this contraindicated technology?
While using the power of Mega Evolution, the protagonist must face its dangers.
Maybe we’ll even get to know the source of the power of the legendary Pokemon “Yveltal (death)” and “Xerneas (life).”

Summary: Looking forward to a story for adults

Legends Arceus was also like that, but the Legends series is more serious than the main story, and is characterized by many depictions that are a little scary.
The history of war and weapons behind the glamorous streets of Paris.
It looks like it will be an irresistible work for those who like research.
