A physical body based on the "Beast of Life" naturally possessed the foundation of a demigod, along with the potential to become a god.
Therefore, at the very least, their physical bodies would not become shackles restricting their growth.
However, no matter how they grew, once their consciousness returned to the Magitech Cards and they became Magic Spirits once more, their attributes remained unchanged. After all, at that point, they were merely the pilots of their original bodies and could not alter the bodies themselves.
Next came the most crucial evolution test. First was the Digimon representative, "Little Devil."
Dark tested all kinds of Great Sin Cards on it and obtained complete, reversible evolution results every time.
Then came the Pokémon representative, "Eevee." The test results differed greatly from what he had expected.
Eevee's evolution completely defied the basic framework of Pokémon. It could actually devolve as well!
At first, Dark believed this was most likely due to Eevee's unique nature as a Pokémon.
But as his research progressed, he gradually discovered that evolutions brought about through Great Sin Cards or Soul Bonds should both be classified as "evolutions driven by external forces."
Mega Evolution was a typical example.
Even for creatures like Pokémon, this was a special kind of evolution that could result in "devolution."
The reason Mega Evolution could be reversed was that a substantial portion of its evolutionary energy came from an "external" source.
By the same logic, Dynamax and Terastallization were also temporary evolutions.
Using Great Sin Cards or Soul Bonds to evolve Pokémon was, in essence, also "evolution driven by external forces." The latter in particular was practically the prototype of Mega Evolution.
Pokémon that evolved this way naturally had the possibility of devolving as well.
But if he continued this line of thought—
He
