Ultra Beast

[Super Saiyan Overlord1007]

What do you think of them.

Also would you consider: Lunala/Solgaleo and Necrozma as Ultra Beast? As far as the game lore goes the cares mention they think that may be Ultra Beast (Kind of like how Type: Null/Silvally in the game lore is considered "Legendary" or special to a degree), but as far as general mechanics go are they standard Legendary Pokémon?

I haven't bothered catching them. I don't classify Lunala and the lion as ultra beasts though, I can tell you that.

Solgaleo/Lunala definitely aren't Ultra Beasts. The Pokedex also debunks the notion of Necrozma being one.

As for what I think of them, some of their designs are pretty interesting, my favourites being Buzzwole and Pheromosa. It is a pity how broken they are, making competitive play somewhat predictable.
