- These Legendary Pokémon are only available in Pokémon Crystal, as well as the remakes.
- There's only a chance to fight with Raikou once, and when defeated or ran away; Raikou flees. Likewise, if Entei or Suicune flee; they too cannot be found again once defeated as they roam through Johto's landscapes without pattern at a fast pace with only one chance battle.
