The Dark Dragon Balls (暗黒ドラゴンボール Ankoku Doragon Bōru) are a set of Dragon Balls created by Xeno Dende for the Dark Empire. When created they scatter through time and space, and summon Dark Shenron when gathered.
The Dark Dragon Balls are a set of dark red Dragon Balls with a black colored star. When created, the Dragon Balls scatter through time and space, each ball merging with an evil entity to power them up.
The dark energy of the Dark Dragon Balls can cause transformations in their hosts, such as in the case of Xeno Janemba - who was able to transform into his Evil Demon form thanks to the negative energy of the Dark Dragon Balls - and Xeno Turles - who gained his Rampaging state thanks to the dark power combining with the power from the Fruit of the Tree of Might.
When all seven are gathered they can be used in the same way as the Earth Dragon Balls to summon Dark Shenron. A single wish from the Dark Dragon Balls produces enough negative energy to create a set of Shadow Dragons, similarly tainted with demonic energy.
Dragon Ball Heroes
Dark Empire Saga
Main article: Dark Empire Saga The Dark Dragon Balls are created by Xeno Dende on the orders of Mechikabura and Towa, but immediately scatter through time and space before they can be used to make a wish.
The first Dark Dragon Ball merges with Frieza from the Namek Saga, who is transported through time along with his henchmen Zarbon and Dodoria, and the second Dark Dragon Ball merges with Cell. Both villains join forces with the Dark Empire to fight the investigating Time Patrol, but they are defeated and their Dragon Balls are both taken by the Dark Empire. The third Dark Dragon Ball merges with Kid Buu from an altered version of the Majin Buu Saga, who uses the ball's power to brainwash Babidi's Forces. He absorbs Dabura and escapes through a portal to hunt down the other Dark Dragon Balls.
The fourth Dark Dragon Ball merges with Turles, who uses the ball to empower the Turles Crusher Corps. During his fight with Xeno Goku at the Tree of Might, the energy from his Dark Dragon Ball reacts to the Fruit of the Tree of Might, causing him to take on his Rampaging form. Xeno Turles is killed by Xeno Goku, and the discarded Dark Dragon Ball is later retrieved by the Dark Empire. The fifth Dark Dragon Ball merges with Xeno Janemba and allows him to take on an Evil Demon form, but Xeno Majin Buu enters through a portal and absorbs Xeno Janemba to claim his Dragon Ball, before escaping through another portal.
The sixth Dark Dragon Ball merges with Xeno Lord Slug, who fights a three-way battle against the Time Patrol, the Dark Empire and Xeno Majin Buu. Xeno Majin Buu and Xeno Lord Slug are both killed during the fight, and their Dragon Balls are seized by the Dark Empire. The last Dark Dragon Ball merges with Super Saiyan 4 Dark Broly, who is captured by Xeno Paragus while sleeping in Hell. After resisting Towa's attempt at brainwashing him and charging into the Demon Realm to fight Xeno Goku, Dark Broly is knocked out by the Time Patrol, Mira swooping in to take his Dark Dragon Ball.
