Kanto birds are just rarely seen
Johto beasts are said to be individuals, but there’s shinies in the Zoroark movie and I think Suicune shows up multiple times in the anime? Don’t watch it
Hoenn titans can be made at will by Gigas, duplicates confirmed to exist in Hoenn, Sinnoh, and Galar
Eon duo lives in flocks
Sinnoh pixies only make sense as single specimens
Unova genies + Enamorus, 4 Musketeers, Island Guardians all seem to be single specimens
The games handwave this away through Dynamax Adventure / Ultra Wormhole just accessing random multiverses to catch their single specimen legendary, so you can have duplicates show up to shill dlc
