Flavor: Solastor and Lullux are Pokémon made out of the essence of the stars, stemming from the same evolutionary tree as Lunatone and Solrock. Solastor is based off Castor and the sun, and radiates a thousand degrees of solar energy per second, spreading it to all of those in need. When it reaches half health, however, it loses control of itself and becomes a giant star eater, obsessed with consuming solar power to fuel its own attacks. It's said that if you see a Solastor in the bright sky, the rest of the day will have clear skies.
Role: Powerful sweeper that gets even stronger at half health. Can help fry Grass and Bug-types, and can also fit into Sun-based teams with it's ability to set up the sun.

Flavor: Lullux is based off Pollux and the moon, and is a calm individual that likes nothing more than to gaze out at the stars, especially at the night sky. When it reaches half health, it becomes a giant moon that rests all day, building up it's energy to surround the night sky in a bright blue aurora that is cooler than any known material. It's said that if you see a Lullux in the darkest night, it is a sign that the skies are clear enough to see the stars.
Role: A rather unique wall that can set up Rain to support other Pokémon.
