Super Dragon Ball Heroes: Ankoku Makai Mission!

Shortly after defeating Cell in his own timeline, Future Trunks takes on a new role as a Time Patroller. Working alongside Chronoa, he faces a formidable threat known initially as the Time Breakers, who are later revealed to be the Dark Empire Forces originating from the Demon Realm. This sinister faction has successfully resurrected their ancient leader, Mechikabura, and sets into motion a dangerous plan to restore him to the prime of his youth. To achieve this resurrection, the Dark Empire seeks out powerful artifacts called the Dark Dragon Balls, which have been scattered across time and space. However, these mystical orbs have unexpectedly merged with villains from the past, granting those adversaries terrifying new levels of power. With history itself at risk of being rewritten by these empowered enemies, the stakes have never been higher for the Time Patrol. Future Trunks cannot face this escalating crisis alone. Joined by new allies, including Goku and Vegeta, he must journey through fractured timelines to track down the corrupted artifacts. Together, they must battle these enhanced foes and put an end to the Dark Empire’s ambitions before Mechikabura can reclaim his full strength and plunge all of reality into darkness.
