I always assumed the dragonzord could talk since it could fight on it's own, but didn't speak English, but a language that sounded to humans like roaring & such. & the wild zords could talk to at least the red guy, in their own way, same with the galaxy beasts and one of the galaxy rangers, as I recall, though i've noet seen all the episodes of either series. But it did seem the vast majority seemed to be non sentient.
I wonder if Agumina as the same digivolutions as the season 1, or 5 Agumon, or different ones.
