Floette is a small Pokémon with a white upper body and a green lower body. Its eyes are black with a green, plant-like extension over each similar to eyelashes. It has long, notched ears with a yellow ring around the base of each. Its tail is spade-shaped, and it has thin arms with mitten-like hands. It is a female-only species with no male counterpart.
Floette also holds a flower with five rounded petals that can be red, yellow, orange, blue, or white. The flower has three yellow stamens and a long green stem with a single leaf. A more gorgeous flower contains more power for Floette. It flutters around and cares for flowers by giving its own power to them. If the flowers of a well-tended flower bed bloom, Floette celebrates with an elegant dance. However, it will never forgive anyone who tramples a flowerbed.
The Eternal Flower Floette, the Floette that befriended AZ, is different from a normal Floette. Its tail and eyebrows are blue and the rings around its ears are red. Its flower is different as well and no longer blooms anywhere. It has six petals instead of five: three that are big and three that are smaller. The stem is red and leafless, and stigma is black and conical. The flower's underside is black and the top of the three big petals are patterned red and black. This flower contains terrifying energy. The Eternal Flower Floette is the only known Pokémon capable of knowing Light of Ruin.
Multiple Orange, Red, Blue, and Yellow Flower Floette appeared in A Windswept Encounter!, with the Orange Flower Floette making her debut, and the Red Flower and Yellow Flower Floette making their main series debut. The Orange Flower Floette was the object of affection for both Noibat and a wildBreloom, sparking a rivalry between the two.
AZ's Floette appeared in The Redemption. She was initially seen in a flashback of the great war of Kalos, being sent into battle and eventually dying, leading AZ to create the ultimate weapon with which to revive her. It worked, but after using the weapon to destroy both sides of the army and bring the war to an end, Floette realized how many lives were taken for hers, and left him. She finally returned to him after AZ's battle with Calem in Lumiose City.
Pokémon X and Y: 3,000 years ago, AZ befriended a special Floette who died in the ancient Kalos war. AZ created a giant machine to bring his friend to life, and while he succeeded in granting his friend eternal life, his immeasurable grief led him to turn the machine into an immensely powerful weapon. The weapon decimated the armies of both sides, and brought an end to the war. However, upon learning that the weapon drew upon the life of other Pokémon, the Floette left him in disgust. Through the player's actions, however, AZ's grief is lifted, and the two old friends reunite during the credits of the game.
