Mewitti asks:

Have you seen the dialogue in Sword/Shield revealing that Dynamax Pokémon don’t actually physically change size in real life when they Dynamax? I saw an NPC mention it in the postgame content, and it’s also mentioned by Shigeru Ohmori in an interview “101 Rapid-Fire Questions About Pokémon Sword And Shield” at around 2:10:

Interviewer: So does Dynamax, is that like a projection, or a physical transformation?
Ohmori: It’s actually just a visual projection.
Interviewer: So is the real Pokémon still just on the ground doing these moves and it’s like just a big version of that?
Ohmori: Yeah, so the actual Pokémon is in that projection.

May or may not ultimately change anything, but I thought it was an odd reveal that has some interesting implications for worldbuilding.

Yeah, I am aware of this.  I thought it was… odd, because I’d actually considered the possibility beforehand and decided that it wasn’t necessary for Dynamaxing to make sense.  I mean, we already know that Pokémon can do a magical thing that can drastically change their size in an apparent violation of conservation of matter – evolution.  And evolution is permanent; once I’ve bought into that, I don’t have any problem believing that Dynamaxing can temporarily increase the size of a Pokémon’s physical body.  The animations for Dynamaxing also have this feel of mass and physicality to them that I think is weird if it’s meant to be just a projection.  I guess there is, like… a square-cube law argument that a size increase like that would definitely kill most Pokémon, but since when does Pokémon care about anatomical plausibility?  It makes some thematic sense, I’ll give them that, because of Sword and Shield’s interest in spectacle – Dynamaxing is actually all about appearances, style over substance, which would be a weird take on this generation’s flagship mechanic, but actually fits in the context of the story of Piers and Spikemuth.  I feel like it raises more questions than it answers, though.  Like, if the gigantic form is just a projection, why does it make them more powerful?  How does Gigantamaxing fit into this, why is it any different to Dynamaxing, and why can so few Pokémon do it?  Is there a reason Galar needs huge stadiums, if the Pokémon doesn’t physically get larger; like, can the Pokémon not just have the power without the size increase?  And, well, this was a question I had anyway, but what does Eternatus have to do with any of this?

Also, apropos of nothing, I believe this is the same interview where they are asked “are Pokémon sentient?” and Shigeru Ohmori replies “they’re just getting by,” which frankly is an answer that resonates with me much more than it should. Like, sentient? B!tch, today I slept until midday and then played six hours of Fire Emblem; I’ll work on “sentience” next week.
