Ah, okay, let me amend my previous thing about why the Legends starters were chosen - they’re all a reference to Feudal Japan, as well as could be said to reference Japanese animals.
Samurott’s the most obvious, being based on the Samurai. Decidueye is an Archer, not as specific to Japan but still themed around the time. Typhlosion, or rather, Bakufoon is the most tenuous. The name is used to refer to Bakufu, which was the term for a shogun’s officials.
min terms of animals, again, Samurotts the easiest, with sea otters going to northern Japan - aka Hokkaido aka Sinnoh. Honey Badgers like Cyndaquil are also present in Japan, as are a few types of owl.
