Pokémon are remarkable creatures that appear in a wide range of types and sizes, possessing abilities, powers, and personalities as varied as they are plentiful. Doctor Yukinari Ookido has devoted his life to researching these intriguing beings, which can be caught, trained, traded, and battled against one another. However, there is only so much he can accomplish from his laboratory. Keeping this in mind, Ookido entrusts two young boys with a Pokémon of their own and a computerized encyclopedia to catalog them. One of them, Green, is brash, passionate, slightly arrogant, and Doctor Ookido's own nephew. The other boy, Red, is equally passionate and filled with a wide-eyed, mildly naive sense of wonder. Pokémon: The Origin follows Red on his journey through the Kanto region as he attempts to complete his "Pokédex" by capturing and cataloging all existing Pokémon. Along the way, he will discover that there is more to himself and his goals than he originally thought. Red will have to put both himself and his Pokémon to the test in special Gyms, whose leaders serve as steps along the path to the Pokémon League, in order to challenge the Elite Four and become a Pokémon League Champion. Aside from his goal of becoming a Champion, Red faces other brewing problems. There are others who capture and train Pokémon for more sinister reasons, with the infamous criminal organization Team Rocket being one of them. If Red can defeat them, fellow trainers, his rival Green, and wild Pokémon throughout Kanto, he just may fulfill his own dream, as well as Doctor Ookido's.
