Kukui also did a lot of these references in gen 7. Avery as well makes a lot of them, as well as various random NPCs every so often.While we're talking about the Armor rivals, I just noticed in my rematch against Avery that he also references Pokemon Natures, such as when you land a Super effective hit. He says something like: "S-supereffective? Your Nature certainly isn't Calm, is it?" with Nature and Calm capitalized. I thought that was neat. I wonder if he references them more?
