The name of the next Pokemon game could be "Great Detective Pikachu" if a new trademark filed in Japan is any indication. All About Pokemon Figure (via NintendoLife) dug up the trademark, which was originally filed by Nintendo and Game Freak on October 11.
It is possible that Great Detective Pikachu is the name of the all-new Pokemon detective adventure game revealed last week. This game will reportedly have players solving mysteries with Pikachu acting as a sidekick.
A special blue Pikachu will also reportedly feature in game, who can speak, though it is unclear if the talking Pikachu is the game's antagonist.
As with all trademark filings, many of which go unused, it is possible that Nintendo and Game Freak are merely covering their bases by trademarking Great Detective Pikachu.
