>>46072910Based on the soup shit, it depends on their diet. Still doesn't explain why and how they change before forming the giant bodies of light
>>46072975Except pokemon don't get bigger when they go Max and that still explains nothing about Gigantamax. Eternatus is the giant pokemon and other pokemon can use his energy to reproduce its size with a holo-like projection, but there's no explanation for the transformation some pokemon experience upon projecting their energy.
This is how a Charizard with the G-factor looks BEFORE he creates the projection. But why? Why does he change to this? How? This isn't a dose of energy that translates into more powerful moves like Z Power nor the hidden potential of its species like Megaevolution, it's something that just happens before he goes kaiju mode
