Naruto: Ultimate Ninja 2, known in Japan as Naruto: Narutimate Hero 2 (ＮＡＲＵＴＯ－ナルト－ ナルティメットヒーロー２ Naruto: Narutimetto Hīrō 2?), is the second installment of the fighting game series Naruto: Ultimate Ninja. Like some other Naruto games in Japan, this one was available in two covers: one featuring Naruto Uzumaki along with several different characters in the background, and the other with Sasuke Uchiha and several other characters. The game was released on September 30, 2004 in Japan, June 13, 2007 in North America, and October 19, 2007 in Europe.[1]

Ultimate Ninja 2 features a similar gameplay experience to Ultimate Ninja, featuring many of the same gameplay elements and geography. The game replaces the arcade-style story mode from the original game with an RPG-esque story mode that loosely covers the events up to episode 96 in the anime as well as a filler arc made up for the game involving a special seal made by Orochimaru. This is the last game to feature support characters until Ultimate Ninja 5 as they were excluded in Ultimate Ninja 3. This time, the support characters are no longer fixed and all characters in the game have the ability to become support characters.

There is a total of 32 characters featured in the game (33 in the Japanese version with the inclusion of Doto Kazahana as a promotion for the movie Naruto the Movie: Ninja Clash in the Land of Snow. The promotion also include two stages from the movie that were not included in the overseas version). All characters have the ability to activate special modes during battle (unlike the original game which restrict the modes to several characters).
