Glimmora is a coned flower Pokémon. It has three light green crystalline petals as a tail. The tail is connected to four light purple crystalline petals with light green lines each. The head is black with yellow eyes and a transparent black cone. The six head crystalline petal are colored dark blue with light green lines and four light green rectangles shapes at end of each petal.
Glimmora can move by floating and closing its petals. It can latch onto walls to disguise itself as a plant. Should Glimmora sense danger, it will open all its petals to unleash a beam attack in retaliation. Glimmora's petals are filled with crystallized poison. It has been observed that Glimmora's petals resemble the Tera Jewels that are seen when a Pokémon Terastallizes, many of them (along with its pre-evolution) can be found in Area Zero, the place where the Terastal phenomenon originates, and eight Glimmet Crystals are need to make TM171 (Tera Blast), a move that changes type with Terastalizing. It is currently unconfirmed whether there is a connection between Terastallization and Glimmora, however.
Glimmora is the only known Pokémon capable of learning the move Mortal Spin.
Glimmora's blue-like petals and bud-like shape may be based on the passiflora, specifically the passiflora caerulea, a South American native plant that was introduced in Spain and now grows in the wild. The blue passion flower has been used in traditional medicine as a sedative and liberates toxic substances such as cyanide when boiled. Glimmora's Rock-type might be inspired by the extreme hard bark and external bud that protects the petals of the blue passion flower before blooming. Its appearance may also be based on cherry-like black fruits of deadly nightshade, and purple petals and conical stamens of bittersweet nightshade; both of which are poisonous plants.
Glimmora and its pre-evolved form may also be based on a variety of animals with sessile habits, like sea anemones, crinoids, and most notably some species of sea sponge, some of which may bear resemblance to flowers, like the carnivorous demosponges of the clade cladorhizidae. It's common for sponges to use mineralized spicules and chemical deterrents as a form of defense mechanism, which may be the source of inspiration for its Toxic Debris ability.
It may also reference copper(II) sulfate, a toxic inorganic compound taking the form of blue crystals. Its flower-like characteristics may specifically be a reference to the copper(II) sulfate hydrate chalcanthite.
Glimmora may be a combination of glimmer and flora. It may also include ore.
Kiraflor may be a combination of キラキラ kirakira (onomatopoeia for glittering), killer, and flor (Spanish and Portuguese for flower).
