Hitmonchan debuted in Pokemon Red and Green in Japan in 1996, inspired by boxer Hiroyuki Ebihara, which explains its Japanese name Ebiwalar. Like other Generation I Pokemon, its cry was made for the Game Boy's limited sound hardware, giving it a harsh electronic tone distinct from its anime voice. Fans later extracted these cries from the games and shared them on forums and soundboards, where Hitmonchan's short call became a nostalgic favourite for battle edits and retro gaming posts.
