How many unique Pokemon in SWSH + DLC + Zarude?

Solution 1:

Based on a Python script I wrote parsing data from Serebii, there are 664 unique Pokémon in Sword and Shield.

  1. 80 of the Pokémon do not exist within the various Pokédexes. 68 are legendaries, ultra beasts, and past generation starters. 12 are Mythicals.

  2. 584 of the Pokémon are unique species within the various Pokédexes
