Lurantis is a plant-like Pokémon that resembles an insect. The top half of its head is light pink, while the bottom half is white. It has light red eyes and two green antennae with a small green lump between them. There are four extensions to the top half of its head: two on the top with red tips that resemble ears, and one on each side with white tips that resemble stylized hair. It has a light pink body with wavy, skirt-like extensions around the waist and a green abdomen and neck. Its thin, white arms end in large, red scythes with white along the bottom rim and a single green claw on the tip. There are vertical, pink-and-red stripes down its legs, which have small, pointed green feet. The coloring and shape of Lurantis's body and arms give it the appearance of wearing a long-sleeved dress, while its legs are similar to pants. Four red, wing-like appendages sprout from its back, each tipped with white.
Lurantis both looks and smells like a flower, a trait that it exploits to lure foes in for a surprise attack. Its brilliant coloration and elegant moves have earned it acclaim as the most glamorous Grass-type Pokémon. However, it does disguise itself as a Bug Pokémon for protection. Maintaining its appearance requires detailed grooming. If a Trainer does a good job caring for it, Lurantis will have an easier time trusting them than a lazy Trainer.
Lurantis is capable of firing beams using its sickle-like arms. These beams can cleave metal plates and allow it to perform its signature moveSolar Blade.
A Totem Lurantis debuted in PASM14. In order to get strong enough to face the Ultra Beasts threatening to invade Alola, Moon summoned Lurantis to Konikoni City with a soup made by Mallow and battled it as a form of training. Despite the assistance of many ally Pokémon, Lurantis was eventually defeated by Moon's Mareanie.
