Pokémate is a Nintendo published, Square Enix developed cell phone application released in Japan in December of 2006. In it, players are given a random Starter Pokémon and are subsequently able to capture Pokémon. The Pokémon they capture can then be used as the person's avatar when chatting with friends. The application costs 210 yen per month.
Square Enix has been involved with many mobile applications based on preexisting properties including Final Fantasy, Dragon Quest, and Kingdom Hearts.
Despite being shown at E3 in 2006, Nintendo never released the application outside of Japan. There are currently no plans to release it in North America or PAL regions, and it appears as if Nintendo has abandoned all plans to do so.
