Dispatch! Time Patrol is the first chapter of Super Dragon Ball Heroes: Dark Demon Realm Mission.
Shortly after his death at the conclusion of the Cell Games Future Trunks was revived by the Dragon Balls and headed back to his future, where he restored peace by destroying the evil Future Androids, and then Future Cell three years later. However soon after Future Trunks found himself in the Time Nest. Startled, he soon received another surprise as the Supreme Kai of Time appeared and attacked him, he managed to evade her and she explained that his usage of a Time Machine was against the law. After explaining that Towa and Mira were causing trouble, the Time Kai decides that Future Trunks can serve as a member of the Time Patrol, and gifts him with his "Xeno Trunks" clothes.
The Supreme Kai of Time and Future Trunks head to confront Towa and Mira in their hideout, but Mira quickly attacks with an energy blast, terrifying the Kai. Future Trunks manages to deflect it with his sword, however Mira sends the Masked Saiyan to combat him, finding himself overwhelmed in his base form by the Masked Saiyan, Future Trunks ascends to Super Saiyan and is able to fight on even grounds with him, eventually managing to land a blow that cracks his mask. Mira is enraged by this and transforms into Super Mira, however before Mira can overwhelm Future Trunks, he is hit with an energy wave from behind by the Masked Saiyan, whose mask crumbles - revealing his identity as Bardock. Future Trunks teams up with Bardock to fight Super Mira, and are able to fight on even grounds with him and eventually overwhelm him. However Towa teleports herself and Mira away before the battle can conclude.
After a brief conversation with Bardock, Future Trunks heads back to the Time Nest. The Supreme Kai of Time explains the Demon Realm to Future Trunks, when Demigra unexpectedly appears. After a brief conversation, Future Trunks prepares to fight after Demigra notices Tokitoki. However at that moment, Goku arrives (with his Xeno Goku look).
