Are wild Pokemon able to Gigantamax and Dynamax without a trainer?

Question

I should know this already, but it just nags in my mind. I need to be sure of it.

Answer 1

Only wild Pokemon found in Raid Dens are able to D-max or G-max. Otherwise, no, wild Pokemon cannot D-max.

There are a couple of story encounters where a small number of wild Pokemon are able to D-max, but that is explained in the post-game Swordward/Shieldbert story.
