Photosynthesis

Leafeon is a mammalian, quadrupedal Pokémon. Its body is tan with dark brown paws. It has a multitude of small green sprouts growing all over its legs, chest, and back, with the longest one on its head, in front of four tan tufts of fur. Leafeon's green ears and tail resemble tattered leaves. It has brown eyes and a small, brown nose. The cells in Leafeon's fur are closer in nature to a plant's cells than an animal's, which allows it to use photosynthesis and purify the air around it while sleeping under the sunlight; it gets its energy this way instead of eating. It is a pacifistic Pokémon who prefers not to fight, though it will sharpen its hard, leafy tail to protect its friends from harm. The tail's sharpness is said to exceed that of a human-crafted sword, being able to cut down a large tree with one hit. Leafeon's aroma is similar to fresh grass. Once the user has been transformed into a Leafeon, they will gain all of these traits and mannerisms.
