From left to right:
Alolan Raichu - this is what Pikachu evolves into in Alola. He's surfing on his tail :)
Comfey - an aromatheraputic fairy-lei. "It has a habit of giving these flower rings to those it's fond of. The aroma can soothe both itself and its allies. Comfey also helps with the treatment of people and Pokémon at the Pokémon Centers and hospitals"
Lurantis - A grass-type Pokemon based on the real "orchid mantis." It absorbs light and then attacks with a solar blade.
Morelull - Called the "Illuminating Pokemon" because it's a nocturnal creature that spreads glowing spores through the forest.
Minior - This is a meteor. If it's attacked, its hard rock shell breaks off to reveal a colorful core inside. They spin and glow and it's a surprise which color is inside each one. They remind me of geodes and my plan is to name them Meteor-1, Meteor-2, etc.
Brionne - In each Pokemon game, you have a choice of which one will be your first partner. In this game, the choice is between an owl, seal, and kitten. I haven't totally decided which I'll choose, but I think it will be the seal Brionne. She's a pop star who dances, swims, and blows colorful bubbles through the air. ^_^ "It’s said that Brionne will only reveal a sad expression to a Pokémon or Trainer to whom it has opened its heart completely."
Ribombee - "Ribombee collect flower nectar and pollen to make into balls known as Pollen Puffs. ... Some of the Pollen Puffs that Ribombee make also have relaxing effects or can relieve tiredness. These are distributed around the Alola region as high-priced supplements."
Oricorio - There are four versions of Oricorio in the game, each based on a different style of dance. I like the pink Pa'u style best, I think; but there are also Spanish style baile, American cheerleaders, and Japanese sensu dancing birds.
