Some of the newest Pokémon include Diancie and Hoopa as of December 2015. These two Pokémon are numbers 719 and 720 in the Pokédex respectively, making their first appearances in “Pokémon X” and “Pokémon Y,” which were the fourth generation of Pokémon games.
In the Pokémon world, Diancie is a transformation of Carbink, but Carbink doesn't naturally evolve into Diancie. The glimmering pink body of Diancie is one of the loveliest sights in the Pokémon universe, according to Nintendo's official Pokémon website. It is a rock- and fairy-type Pokémon, so it is weak to steel, water and grass types. Diancie weighs 19.4 pounds and stands 2 feet 4 inches high.
Hoopa is a psychic- and ghost-type Pokémon and is said to have a huge amount of power in its true form. Legends of the Pokémon tell of it carrying off an entire castle so that it could gain access to the treasure hidden within. This Pokémon is weak to ghost and dark Pokémon. It weighs 19.8 pounds and measures 1 foot 8 inches tall.
Fairy-type Pokémon are relatively new. The Pokémon Company first introduced them in “Pokémon X” and “Pokémon Y.” As of 2015, this was the newest Pokémon type released since the developer introduced dark and steel types in “Pokémon Gold” and “Pokémon Silver.”
