Naruto: Ultimate Ninja Heroes is a North America and PAL region-exclusive fighting game developed by CyberConnect2 and MiCROViSion and published by Namco Bandai Games for PlayStation Portable in 2007. It is the first installment of the Heroes series in the west; it is also essentially an edited version of Naruto: Ultimate Ninja Heroes 2: The Phantom Fortress, serving as a prequel to the next game, as the Japanese dub is not included in this game, essentially turning the game into a scaled down version of Naruto: Ultimate Ninja 2.
