Pokémon Adventures, released in Japan as Pocket Monsters: Special (ポケットモンスター SPECIAL, Poketto Monsutā Supesharu), is a manga based on the Pokémon gameboy games rather than the Pokémon anime.
Satoshi Tajiri, creator of Pokémon, once stated that Pokémon Adventures is closest to what he imagined the Pokémon world to be: "This is the comic that most resembles the world I was trying to convey." (僕が伝えたかった世界に最も近い漫画です。, Boku ga tsutaetakatta sekai ni mottomo chikai manga desu)
The series is written by Hidenori Kusaka and was illustrated by Mato for the first 9 volumes. When Mato became ill and was unable to continue illustrating the series, Satoshi Yamamoto took over as the illustrator and still continues as the series artist.
