Cross-series structural rarity
Explore the rarest Pokémon using a transparent structural rarity model based on official category, acquisition history, breeding constraints and capture difficulty.
There is no single permanently rarest Pokémon across every game. In this structural ranking, event-distributed Mythical Pokémon occupy the highest tier, with shared positions used instead of false differences between equal scores.

Category cards update the complete ranking filter. Counts can overlap because Ultra Beasts and Paradox Pokémon are also non-Mythical, non-Legendary structural rarity groups.
These entries are not Mythical or Legendary, but still carry special structural rarity signals such as Ultra Beast or Paradox classification.

The score combines official category, acquisition pattern, reproduction constraints and capture difficulty. Capture rate measures how difficult a Pokémon is to catch after encountering it; it does not represent encounter frequency.

Worked example
Jirachi is officially Mythical and receives the strongest structural rarity weight. The score reflects category, distribution history, breeding constraints and capture difficulty—not current availability in a specific game.
65 + 20 + 8 + 7 = 100
