==Game Version==
===Dark Demon Realm Invasion===
thumb|left|The battle begins in the Demon Realm
The Time Patrol learn that the Demon Realm has been unsealed, and enter the realm to investigate, where they are attacked outside Mechikabura's Tower by the Masked Saiyan. They manage to crack his mask, which causes Mira and the other Time Breakers to arrive to help him. The Time Patrol manage to completely break the Masked Saiyan's mask, which causes the Masked Saiyan to transform into a Great Ape, but they defeat him. The Masked Saiyan, revealed to be a brainwashed Bardock, is released from Mira's control, and he joins forces with the Time Patrol.
During the ensuing battle, Trunks and Bardock both power up into their Super Saiyan 2 forms, before transforming further into Super Saiyan 3s. Mira also transforms, first into his Runaway state before fully achieving his Super Mira form. Both the Supreme Kai of Time and Towa also join the battle, with the Time Patrol and Bardock cornering Mira and Towa.
Super Mira and Towa battle the Time Patrol, but find themselves on the losing end of the battle. A dark portal appears behind Mira and Towa, and Xeno Dabura emerges from the portal to aid them in battle. Despite his help, the Time Patrol manage to deal a fatal blow to Towa, who collapses in Xeno Dabura's arms. Xeno Dabura despairs over the death of his sister as he and Mira escape with her body through a portal.
===Assault on the Hell Gate===
After Towa's death at the hands of the Time Patrol, there was peace for a time, however Towa's hatred caused her to revive as "Dark Towa". Thirsting for revenge, Towa travelled to the timeline of Dragon Ball GT and opened three Hell Gates, the gates of Ice, Fire, and Chaos.
Xeno Trunks arrives in the timeline, finding that the opening of the Hell Gates has caused villains to escape from Hell and run rampant. Dr. Gero and Dr. Myuu have also returned, and they once again create Super 17. Trunks teams up with the Dragon Team to fight Super 17, who is aided by Dark Towa. Super 17 forcibly absorbs Android 18 during the battle, greatly increasing his power. During the battle Gohan is able to attain the Super Saiyan 4 transformation, and together the group are able to deal enough damage to force Super 17 and Towa to retreat into the Hell Gates.
Trunks faces off against many enemies inside the Hell Gates, including a resurrected Janemba. In the Ice Hell Gate he faces off against Super 17, who he manages to permanently put down. In the Fire Gate he fights the assembled Time Breakers, before facing off with Dark Towa again. The villains retreat into the Chaos Hell Gate, where Dark Towa, Super Mira and Xeno Dabura have a rematch with Trunks.
Trunks manages to defeat the trio who are suddenly taken out from behind by Broly, who arrives in his new Super Saiyan 4 Full Power form. He then proceeds to battle Trunks, but is defeated and killed once again.
===Birth of the Dark Demon Realm===
Chronoa detects a time-space distortion 75 million years in the past, and sends the Time Patrol to investigate. They are attacked by a brainwashed Great Ape Gohan but they manage to defeat him, and wonder about the source of his dark ki. They meet a young Demigra and ask him about the distortion, but he asks how they could know about it and attacks them. After forcing him to retreat, Chronoa suggests asking her younger self.
The Time Patrol arrive at Chronoa's home, but Chronoa is distrustful and tries to force them to leave. After forcing her to calm down, Chronoa explains her past to the Time Patrol, and gives her suspicions on Demigra's treatment of Tokitoki. Chronoa asks them to head to Demigra Castle and expose his scheme. On their way to the castle they spot Mr. Satan hiding behind a rock, menaced by Turles, Metal Cooler and Janemba, and save him from the villains.
The Time Patrol confront Demigra and his associates Gravy and Putine, only to find the present Demigra aiding them. He explains that he had become a Demon God and calls his past self a fool for not using Tokitoki's power to become a god, before amplifying his ki. He then teams up with his past self to fight the Time Patrol, both Demigras are defeated. Upon his defeat, Demon God Demigra states that he will definitely be revived again before vanishing.
===Demon God Demigra===
Demon God Demigra revives in the present and returns to his castle, allying with the Time Breakers. Mira attacks a city on Earth to lure out the Time Patrol, allowing Towa to kidnap Xeno Vegeta and brainwash him into the Black-Masked Saiyan. The Time Patrol confront the Time Breaker alliance and manage to release Xeno Vegeta from Time Breaker control. Demigra responds by transforming into his Final Form, but after being overwhelmed reveals that he has ascended beyond even that form and transforms into his Transcended form before retreating. The Time Patrol give pursuit, fighting their way past the Time Breakers and the returned Gravy and Putine, before engaging in battle with Demigra, Dark Towa, Xeno Dabura and Super Mira. In the end, they successfully defeat Demigra once more and seal him back inside the Crack of Time, but Towa gained enough energy from the events to break the seal on Mechikabura.
==Game and Manga Differences==
*Besides the appearance of the main characters, and the transformation of Super Mira due to being enraged that Xeno Bardock is broken out of his control, the stories are almost completely different, the manga version taking place at the time Future Trunks was first recruited as a Time Patroller while the game's storyline is taking place long after.
**How Future Trunks was recruited as a Time Patroller is shown in the manga chapter, a part of the story not shown in any of the games.
*The King Piccolo Saga and Baby Hatchiyack Saga are only connected to the Dark Demon Realm Saga as a whole in their trailers, as neither Towa or the Time Patrol appear in the sagas during the game.
