Why don't Solgaleo and Lunala have a gender?

Question

It's mentioned in the Pokedex entries that Solagleo and Lunala are male and female evolutions of Cosmog, yet they're both completely genderless in-game. Is there a particular reason for this?

Comments

I’d guess because people don’t know enough about them. They are “legendary” for a reason, and clearly not well known species in the Pokémon games

maybe the dex entry sclaim them as masculine and feminine but they are not actually gendered

Consistency with most of the other legendaries.

This is also a trivial one!

There would also be notable flaws in that evolving a cosmoem in Moon/Ultra Moon will produce a Lunala, but bringing the same exact cosmoem to Sun/Ultra Sun and evolving it will produce a Solgaleo. :P

Answer 1

Lunala and Solgaleo are aliens, and may not have the same gender system the rest of the Pokemon world has.

Lunala, for instance, is said to "live in another world."

Said to live in another world, this Pokémon devours light, drawing the moonless dark veil of night over the brightness of day.

Solgaleo's Sun entry says the same.

It is said to live in another world. The intense light it radiates from the surface of its body can make the darkest of nights light up like midday.

All Box-art legendaries are genderless as well.
