Leafeon was introduced in Pokemon Diamond and Pearl, released in Japan in 2006, as one of two new Eevee evolutions alongside Glaceon. In the original games it evolved near a Moss Rock, with later titles also allowing a Leaf Stone. The character later appeared across the anime, movies, cards and merchandise, building a steady fan following. Its short cry has since been clipped for soundboards and fan edits, where Pokemon fans use it as a recognisable call for one of the most popular Eeveelutions.
