Sun & Moon

Steelix

Tempered underground under high pressure and heat, its body is harder than any metal.

Sun & Moon

Onix

Burrows at high speed in search of food. The tunnels it leaves are used as homes by Diglett.

Sun & Moon

Poipole

This Ultra Beast is well enough liked to be chosen as a first partner in its own world.

Sun & Moon

Necrozma

It looks somehow pained as it rages around in search of light, which serves as its energy. It's apparently from another world.

Sun & Moon

Cosmog

Even though its helpless, gaseous body can be blown away by the slightest breeze, it doesn't seem to care.

Sun & Moon

Salazzle

Salazzle lives deep in caves and forces the Salandit it has attracted with its pheromones to serve it.

Sun & Moon

Salandit

The males will do whatever the females tell them. They give the females most of their food. Due to malnutrition, the males can't evolve.

Sun & Moon

Toxapex

To attack, this Pokémon sends toxic spikes flying at its enemies. Ones that come close get mown down by the claws on its feet.

Sun & Moon

Mareanie

They eat Corsola branches, so Mareanie are hated by craftsmen who work with Corsola branches that have naturally fallen off.

Sun & Moon

Aegislash

Generations of kings were attended by these Pokémon, which used their spectral power to manipulate and control people and Pokémon.

Sun & Moon

Doublade

When Honedge evolves, it divides into two swords, which cooperate via telepathy to coordinate attacks and slash their enemies to ribbons.

Sun & Moon

Honedge

Apparently this Pokémon is born when a departed spirit inhabits a sword. It attaches itself to people and drinks their life force.
