What is the original full Japanese title abbreviated internationally as Pokémon?

The original full Japanese title abbreviated internationally as Pokémon is Pocket Monsters.

The Japanese franchise title is Poketto Monsutā, written in English as Pocket Monsters. The shortened form Pokémon was used for international branding, with an acute accent over the e to guide pronunciation. The word Pokémon can refer to the franchise as a whole or to one of its fictional creatures.

The name reflects the original concept of carrying creatures in portable devices and collecting them. The first Japanese games were titled Pocket Monsters Red and Pocket Monsters Green, while international releases used Pokémon Red and Pokémon Blue.

A common mix-up is treating Pokémon as a plural word. In official usage, Pokémon remains unchanged whether referring to one creature or many. Thus, “one Pokémon” and “many Pokémon” are both correct forms.
