Digimon Franchise

Digimon (デジモン, dejimon?, short for デジタルモンスター dejitaru monsutā, "Digital Monster") is a popular Japanese series of media and merchandise, including anime, manga, toys, video games, trading card games and other media. Digimon are monsters of various forms living in a "Digital World," a parallel universe that originated from Earth's various communication networks. Digimon is often claimed by detractors to be a rip-off of Pokémon, though they both appeared at about the same time, and have entirely different approaches to monsters
