>>22155494Funny thing, though..."Genderless" was an early mistranslation. The correct term is actually "Gender Unknown" - and it most likely applies to Legendaries in the sense that so few people have encountered them that Pokedex lacks detailed information on their physiology. That being said, the Golem Trio are most likely some of the only Legendary Pokemon without "true" genders.
