Battle Stadium: Shuiesha Legacy

Battle Stadium: Shuiesha Legacy is a crossover game between Shuiesha and other Shonen Jump works. As the name implies, it is the celebration of Shonen History and the biggest crossover between Manga/Anime worlds.

Gameplay
Unlike Battle Stadium D.O.N, the game does not use the tug-of-war style of eliminating your opponents. It is a more simplified platform fighter party game, leaving the game to rely on launching opponents off the stage like Super Smash Bros. Like in Smash, characters use their ultimate move from either a meter or a special item that grants it instantly.

Aside from launching your opponents, players have the opportunity to create rulesets to either be timed battle, stocks or health bar.

Battle Stadium D.O.N previously uses characters from the three biggest franchises hence the title, (D = Dragon Ball, O = One Piece, N = Naruto). This time the roster is considered bigger than Jump Stars or Jump Force.
