Leafeon

Diamond +3: Just like a plant, it uses photosynthesis. As a result, it is always enveloped in clear air.

Platinum +2: It basically does not fight. With cells similar to those of plants, it can perform photosynthesis.

HeartGold / SoulSilver: When you see LEAFEON asleep in a patch of sunshine, you'll know it is using photosynthesis to produce clean air.

Black 2 / White 2: With cells similar to those of plants, it performs photosynthesis inside its body and creates pure air.

X / Omega Ruby: When you see Leafeon asleep in a patch of sunshine, you'll know it is using photosynthesis to produce clean air.

Sun: Its cellular composition is closer to that of a plant than an animal. It uses photosynthesis to produce its energy supply without eating food.

Moon: The younger they are, the more they smell like fresh grass. With age, their fragrance takes on the odor of fallen leaves.

Ultra Sun: Although it doesn't like disputes, it will sharpen the leaf on its tail into a blade and fight if it has to protect its friends.

Ultra Moon: It gets its nutrition from photosynthesis. It lives a quiet life deep in forests where clean rivers flow.

Sword: Galarians favor the distinctive aroma that drifts from this Pokémon's leaves. There's a popular perfume made using that scent.

Shield: This Pokémon's tail is blade sharp, with a fantastic cutting edge that can slice right though large trees.

Legends: Arceus: Cells similar to those of plants have been found in its fur. Its hard tail can fell a large tree with one stroke, and the tail's sharpness exceeds even that of a sword crafted by a master.
