The Dark King Mechikabura is the fourth original saga in Dragon Ball Heroes. It was later adapted into the second part of the Super Dragon Ball Heroes: Dark Demon Realm Mission! manga.
For the characters from the alternate "Xeno" timeline it is set at some point after the Dark Empire Saga though strangely it debuted in-game before the Prison Planet Saga concluded. It occurs in both the Xeno timeline version of Dragon Ball GT and the Demon Realm.
It is composed of several sub-stories:
- Demigra Assault (game only)
- Descent of the Demon Gods
- Death Duel in Darkness
Descent of the Demon Gods
Mechikabura is finally able to escape from the Time Labyrinth that he was previously trapped in due to Chronoa. Now in a perfected state he vows that the revival of the Demon Realm is at hand to his Demon followers now sporting new enhanced Demon God forms.
Elsewhere at the Time Nest, Xeno Goku along with Xeno Vegeta, Xeno Gohan, Xeno Goten and Future Trunks are thanked for the hard work they've so far put in to preserve the time lines by Old Kai. Examining a Time Scroll, Trunks notices another change in history. Believing that it could be due to the Demons involvement once again, the Time Patrol head off to investigate.
In another location at the Shirogame fortress, Chamel informs his master, Demigra, that the Time Patrol have fallen for their bait. Praising him for his work, Demigra, Chamel and another underling named Robelu head off to the same location.
The Time Patrol arrive in a ruined city during a one sided battle between Super Saiyan 4 Gogeta and Omega Shenron. Despite being amazed at the power of the two, Trunks wonders what the timeline abnormality might be. Just then the current timeline observers of the fight consisting of Gohan, Goten, Videl, Pan, Bulma, Uub and more appear from behind them with a few of them firing an energy blast at the Time Patrollers. While Gogeta's attention is bought to the disturbance below, Towa calls upon a mysterious purple Majin known as Fin who appears through a portal and grabs Gogeta before slamming him to the ground.
At the same time, the Time Patrol find themselves locked into a battle with their alternate timeline counterparts, friends and family who appear to be under mind control. Xeno Goten and Future Trunks each battle their alternate selves while Xeno Goku fights against Uub. Trunks notices Towa along with her brother Dabura nearby and demands to know how they got free and whether Chronoa is alright. Towa assures him that she is well while Dabura expresses his desire to test his new found strength. With a light downward swing of his sword, a large energy wave cuts across the city. Vegeta is awestruck by Dabura's power though his warm up hadn't even begun. Dabura begins to power up and swings his sword once again however this time the energy wave is blocked by the timely arrival of Chamel creating an energy barrier.
Demigra orders Robelu to return Dabura's attack and with a twirl of her wand, reverses the wave back at Dabura, cutting him across the shoulder. Distracted by the appearance of the new Demons, Xeno Gohan is punched by Pan. Robelu once again uses her wand and with a tap to the forehead sends both Pan and Videl to sleep. Trunks asks Chamel if he is really sided with Demigra and he is told to just draw his own conclusions from observation. Trunks wonders what Demigra's motives are and if he plans to to unseat Chronoa's position, though Demigra simply expresses that it is convenient to make use of them. Robelu tells Xeno Goku and Xeno Vegeta to fuse and much to Goku's surprise, Vegeta agrees, having felt Dabura's new found might. Becoming Xeno Gogeta, he immediately transforms into a Super Saiyan 4.
Witnessing the resulting fusion, Dabura wonders if it would be in their best interest to retreat seeing that the Time Patrol have allied themselves with Demigra and his minions. Towa agrees but just then a being emerges from the rubble, it is Fin, having now absorbed and gained the power of the present timeline Super Saiyan 4 Gogeta.
Dabura encourages Towa to leave the area along with the now Super Saiyan 4 Gogeta absorbed Fin but she declines wanting to see what Fin can do with his new found might. Xeno Gogeta having recently fused together, asks Robelu if it's alright to go and beat the Demon Gods though she says that he must instead retrieve the Dragon Balls that will be necessary in order to defeat Mechikabura and will first need to vanquish Omega Shenron. Xeno Gogeta agrees and due to being more interested in fighting the Demon Gods than the Shadow Dragon, he says that he will take him down fast.
Omega Shenron emerges from the rubble having been previously struck into a building by the present timeline Gogeta and angrily vows to kill everyone on the battlefield. However before having the chance to do anything, he is immediately defeated and destroyed by Fin. Xeno Gogeta rushes into battle against Fin and soon finds himself at a slight disadvantage.
As Xeno Gohan and Xeno Goten watch from below, Robelu asks Gohan to assist in the battle and says that she shall use her abilities to to unlock more of Gohan's power. Holding up a single screw, she uses her magic abilities to summon up components that build together to create a complete Blutz Wave Generator. Firing it directly at Gohan he begins his transformation into a Great Ape with a nervous onlooking Goten and Future Trunks asking Robelu to shut off the machine.
As the battle between Xeno Gogeta and Fin rages on, Fin is suddenly struck from behind by a Ki blast, turning to see who was responsible he see's the newly formed Super Saiyan 4 Xeno Gohan. Gohan joins the battle and powers up a powerful Masenko which knocks Fin backwards through the air and allows Gogeta to follow up with an Atomic Kamehameha. Amazingly, Fin is still standing and Gohan prepares to attack him again but Gogeta tells him to wait, noticing that the present timeline Gogeta appears to be in control. An upper portion of Fins' face peels away as Gogeta now has complete control of his as well as Fin's body and tells Xeno Gogeta that he just wanted to test Fin's power and have the opportunity to face his counterpart self. With a surge of energy, Gogeta forces Fin to leave his body.
Towa disappointed at the outcome concedes to retreating from the battlefield as Dabura also needs healing due to his injured shoulder but Demigra and Chamel arrive before them to stop them. Chamel knocks the staff from Towa's hands and Demigra who states that he has gathered a lot of magic power together in preparation for his upcoming battle with Mechikabura attacks Dabura saying that he will take care of him quickly so as to not waste any power. However before the attack can land, Demigra is suddenly frozen into place.
Nearby the Time Patrol also find themselves frozen. As Trunks recalls such an ability he then see's a mind controlled Chronoa above along with Gravy and Putine. Gravy uses his hammer and fires a large lightning energy blast towards everyone but they are protected by Robelu's defensive magic. Chamel despite not being able to move is still capable of using his magic and he does so to teleport his allies and the Time Patrol away from the battlefield and to Demigra's lair. Chamel asks why Robelu was not frozen also and she explains that it was because she was elsewhere gathering the Dragon Balls as she holds up a sack that contains all seven.
From behind the group someone wakes up wondering where she is as Gohan calls out in shock at seeing his daughter Xeno Pan having accidentally been brought along with the others by Robelu's magic. She hears from her alternate timeline father that they are members of the Time Patrol. Wondering if her own timeline has been destroyed, Pan decides to join the Time Patrol herself believing that her timeline will be restored if they defeat their enemy and that it would be better served than just hanging out in a gloomy cave all day. Xeno Gohan however is against the idea. Pan asks Robelu if she can give her some new clothes befitting the rest of the group and she obliges.
Demigra begins to use his magic to restore the Dragon Balls energy and tells the Time Patrol to follow Robelu's orders while he does so. Pan asks Demigra what he plans to wish for and why they should follow his orders but Chamel shuts her down for asking too many questions. Using his magic, Chamel opens up a portal showing six separate Hell Gates. He tells the Time Patrol that inside each gate there is a Demon God maintaining barriers to Mechikabura's Palace and that each one must be defeated. Robelu uses her magic to transform Xeno Trunks' sword into a giant key and instructs him to stay behind to use the key to cut off the barriers power as well as slightly weakening the Demon Gods inside each gate.
Xeno Goten heads through the red gate where Dabura is waiting for him. Xeno Vegeta heads through the yellow gate where Gravy taunts him on having beaten him before though Vegeta fires back by saying that now he is at full power he will take him out. Xeno Gohan heads through the black gate only to be surprised that Pan has followed him through as she had been instructed to stay behind to cheer everyone on. On the ground below, Shroom is there waiting for them. He fires off an energy wave from his scythe and Gohan narrowly moves Pan out of the way. Gohan shouts at Pan for being a distraction and she flees the scene in tears. Gohan transforms into a Super Saiyan and engages Shroom in battle. He manages to kick Shroom to the ground but then notices a small cut on his face from the scythe. Gohan falls to the ground and reverts back to his normal state as Shroom tells him that he has harvested some of his spirit.
As he is about to finish off Gohan he is suddenly blasted from behind by Pan who had returned to the battlefield and spurs on her father to get back up. Shrooms begins to make his way over to Pan when Gohan grabs his cloak. When Shroom turns around he see's Gohan standing there now as a Super Saiyan 4. Gohan hits Shroom and knocks him to the floor before patting his daughter on his head and thanking her for saving him. Shroom charges at Gohan with his scythe but in a surprise move instead throws it at Pan. Gohan deflects it however and follows up with a powerful Kamehameha that destroys Shroom at last. Gohan then collapses from exhaustion immediately afterwards.
Back at Demigra's base, Trunks continues to use his key on the six gates and notices that the black gate had lost it's energy, indicating that Gohan must have prevailed. Meanwhile behind the white gate, Chamel faces off against Towa and Fin who still has the same appearance from having absorbed Gogeta earlier. Towa explains that Fin only has to sample someone's DNA once in order to access it again at any point. Towa asks Chamel to switch back to their side but while Chamel is thinking up a plan he is suddenly knocked aside out of the blue by a charging Dark Broly now without his mask.
Inside the Green Hell Gate, Robelu sets her sights on the it's protector Putine. Robelu uses her magic to suspend a horde of Demon Realm Soldiers in mid air while one of them calls out Robelu for being a traitor but she responds by telling him that it is actually Putine who is the traitor due to her once being an underling of Demigra's. Robelu uses the Time Rail technique to send the soldiers crashing into Robelu where they explode on impact. Victorious, Robelu exits through the gate and back to her hideout where her allies are located, including Xeno Vegeta and Xeno Goten who have also been victorious in their efforts against Gravy and Dabura respectively.
Xeno Goku however is still inside the Blue Hell Gate engaging in battle against Salsa. Goku fires a Kamehameha but Salsa swings his sword, producing a gale of wind that sends the energy blast back, causing it to hit Goku directly. Goku charges in for a physical confrontation but is caught up in Salsa's Trick of Tornado technique which cuts away at him. As Salsa rushes in with his sword to put an end to things, Goku counters by using his Power Pole to hit his opponent in the stomach. With the tornado fading, Goku transforms into a Super Saiyan and fires a second Kamehameha to defeat the demon before returning to his friends.
With only Chamel remaining, he returns to the hideout battered and bleeding, recalling to himself how Dark Broly's rampage caused Towa to retreat. The seals broken, the six Hell Gates are destroyed and Robelu begins to explain the next step in their plan that will occur after everyone has regained their health.
However just then Xeno Trunks notices that everyone has frozen in place and turns to see the mind controlled Chronoa floating above him. Chronoa realises that Xeno Trunks was not frozen along with the others due to him wielding the Key Sword and vows to release more of her power. Entering into her adult form, Chronoa uses the Time Clock technique, which sends a barrage of dark arrows that impale Xeno Trunks. Xeno Trunks while holding the Key views segments of Chronoa's memories as she is defeated by Towa and brainwashed by Mechikabura.
Furious, Xeno Trunks transforms into a Super Saiyan 3 and charges at Chronoa. Striking her with the Key Sword, he purifies the darkness within her and returns her to normal along with unfreezing the rest in the hideout. Robelu tells everyone that the next step of their plan has now been achieved as well and now all they must do is wait for Demigra to restore the Dragon Balls. Just then a mass of dark energy comes crashing down upon everyone as Mechikabura emerges a top a nearby tower.
