My brother and I were talking about the chances we could get a Gen 8 Pokemon as DLC and we noticed something interesting. The new region is called the gallor region(or something like that, I'm awful at spelling), which is really close to the British word gallus. A google search for the definition gave me the definition of gallus to be bold, daring, or reckless, which is awfully close to..... brave.
Obviously, this all depends on when the DLC were selected and when the name for the region was set, as well as a few other variables between the two games, but interesting nonetheless. I doubt brave is a gen 8 pokemon, but it's as good as most theories floating around at the moment
