Jump Ultimate Stars

Jump Ultimate Stars (ジャンプアルティメットスターズ, Janpu Arutimetto Sutāzu) is a 2D fighting game developed by Ganbarion in 2006 for the Nintendo DS. It is the sequel to Jump Super Stars and a crossover of a large number of Jump titles, including JoJo's Bizarre Adventure and Steel Ball Run.

Gameplay
Koma (panel) is the term for the characters that the player can use in the game. Each koma uses anywhere from 1 to 7 squares of the koma deck on the bottom DS screen. The deck has 20 squares (4 x 5) on which to place koma. There are three types: help koma, support koma and battle koma.


 * Help koma are only one square large. They boost or help players in the game, but will not appear on the Battle Screen.
 * Support koma are two to three squares large. These koma will show up briefly on the battle screen to help the player - generally by attacking, blocking, restoring health, or some other move.
 * Battle koma are four to seven squares large, and fight throughout each round. These koma represent the characters that the player controls on the battle screen, and the player can switch between characters by tapping their koma in the koma deck like a tag battle.

The player can build and store up to ten koma decks, and each deck must have at least one help koma, one support koma and one battle koma to be valid for use in battle. Ally boosting is done by placing koma next to each other in the deck maker. If the koma placed next to each other are "compatible", their attributes will go up. Battle characters can get a longer health bar, or increase the maximum number of special attack gauges.

JoJo characters in the game

 * Jotaro Kujo: Appears as a battle character, support and help. His special attacks consist primarily of his trademark "Ora Ora!" punches. Many of his koma use one of his Stardust Crusaders companions as his other special attack. His help koma lessens damage taken from special attacks. He is one of the battle characters in the pre-made "Ora Ora", "Hat" and "JoJo" decks.
 * Dio Brando: Appears as a battle character, support and help. His special attacks center on his trademark "Muda Muda!" punches and The World's time-stopping ability.

He is one of the battle characters in the pre-made "Reincarnation" and "JoJo" decks. One of his battle koma can only be unlocked via Jonathan's evolution chart.
