J-Stars Victory VS (ジェイスターズ ビクトリーバーサス) is a crossover fighting video game that combines the universes of several Weekly Shōnen Jump manga series, including former series and some that have been transferred to other magazines. It was released in Japan by Bandai Namco Entertainment on March 19, 2014 for the PlayStation 3 and PlayStation Vita in celebration of the publication's 45th anniversary. A limited edition "Anison" version of the game includes the theme songs from 21 television series, such as "Cha-La Head-Cha-La" and "We Are!", that can be played in-game during battles. The game's own theme song is "Fighting Stars", performed by Hironobu Kageyama, Hiroshi Kitadani, and Akira Kushida.
The game features 52 characters from 32 different series; 39 of these characters are playable fighters, while 13 of them can be summoned by players to provide support during battle. The series included range from older properties such as Dragon Ball, YuYu Hakusho, and Kochira Katsushika-ku Kameari Kōen-mae Hashutsujo, current long-running series such as Naruto, Bleach, One Piece, and JoJo's Bizarre Adventure, to newer series such as Medaka Box, Assassination Classroom, and Beelzebub.
An international release was eventually announced under the slightly altered title J-Stars Victory VS+ for the PlayStation 4, PlayStation 3, and PlayStation Vita. This version includes an additional Arcade Mode that was not present in the original release, while also incorporating game balance adjustments based on feedback from Japanese players. It was released in Europe on June 26, 2015 and in North America on June 30, 2015.
