What if the developers actually using different models for the Dynamax, instead of the resize, because it's the same script of Gigantomax?
I mean, we know about this feature thanks to the leak, and they didn't show it yet, but it seems to be the same of Dynamax and can also change the form of the pokémon. So what i'm trying to say is that they prefered to use the same script of Gigantomax for the Dynamax instead of making another script exclusively for this feature which resize the pokémons.
