Plot
Demon Goddess Towa
Mechikabura is revived
Towa uses energy stolen from strong people in order to revive her grandfather Mechikabura, however his body is old and he cannot move well. Towa tells him to use the Dark Dragon Balls to wish for youth so that he can take revenge on Chronoa, however the Dragon Balls scatter. Mechikabura notices one of them as it heads away, crossing space-time. Towa decides to go and get it but Mechikabura tells her to wait, deciding to grant her Demon God powers first.
It is soon apparent that a Dark Dragon Ball ended up on Namek in Age 762 (during the climax of the Battle of Namek). The ball having fused with the tyrant Xeno Frieza, empowering him to the point that he could overwhelm the newly transformed Super Saiyan Goku - even without using his 100% Full Power. The Time Patrol realize that this is altering history for the worst, and so Xeno Trunks and Goku: Xeno head back to deal with the problem. Goku: Xeno teams up with his past self and the two attack the now full power Xeno Frieza together, as Xeno Frieza holds the two Kamehameha back, Xeno Trunks quickly slices him in half and he loses the Dark Dragon Ball, restoring history to normal as Super Saiyan Goku defeats the non-Dark Dragon Ball Xeno Frieza.
However, Demon God Towa manages to collect the Dark Dragon Ball - though Mira is killed by Xeno Trunks during the process - and brings it back to the Demon Realm with her, where she meets Mechikabura, who reveals that he has summoned more Demon Gods to aid in the search for the Dark Dragon Balls.
Cell X
Chronoa discovers two changes in history and decides to split into two groups, she goes with Goku: Xeno, and Xeno Trunks goes with a new helper - who turns out to be Vegeta: Xeno. Vegeta: Xeno tells Xeno Trunks that he will prove he is the strongest, not Goku: Xeno. Vegeta: Xeno wants to get going immediately, but Chronoa tells him that they all must pose first, Vegeta: Xeno ignores and tells her that they should just get going.
Vegeta: Xeno easily beats Xeno Cell
Vegeta: Xeno and Xeno Trunks arrive back in time, and Vegeta: Xeno gives Xeno Trunks a device from Bulma that can locate the Dark Dragon Balls. The device leads them to the Cell Games arena, where they see the Z Fighters defeated by Xeno Cell, who has a Dark Dragon Ball. Vegeta: Xeno easily beats down Xeno Cell and then destroys most of his body with a Final Flash, shocking Xeno Trunks with his strength. Vegeta: Xeno prepares to finish Xeno Cell but is suddenly attacked by Demon God Gravy before he has the chance. Xeno Trunks catches him as he is sent flying and then places the Potara Earrings he obtained from Chronoa onto himself and the unconscious Vegeta: Xeno, fusing the two into Xeno Vegeks. At the same time Gravy and Putine discuss how great their Demon God power is.
Xeno Vegeks suddenly appears, striking Gravy and announcing his identity, Gravy attempts to attack again but he is easily knocked down by Xeno Vegeks, angering him. Putine states that they must take them down, as they may get in the way in the future. However both parties are surprised as Xeno Cell begins to undergo a Dark Evolution.
Xeno Cell using the power of Dark Evolution transforms into Cell-X, a hulking giant of a being with multiple Spider-like legs that dwarves Xeno Vegeks in size. Whilst Xeno Vegeks is focused on Cell-X, Gravy takes the opportunity to hit Xeno Vegeks from behind, knocking him to the ground. Happy with catching Xeno Vegeks off guard, he too is then caught from behind by an attack from Cell-X who swiped him to the ground, Xeno Vegeks having quickly recovered, suddenly attacks Gravy and they battle briefly before Xeno Vegeks is grabbed by Cell-X and both he and Gravy are crushed as the weight of Cell-X comes crashing down on them both.
Goku: Xeno facing Xeno Majin Buu
With both injured and annoyed at Cell-X getting in the way of their battle, they briefly put aside their fight and attack him in unison with the resulting attack wiping out Cell-X for good. Suddenly Xeno Vegeks diffuses leaving Vegeta: Xeno and Trunks separated once again. As Gravy goes in for the finish on the two Saiyans they are suddenly teleported away by Chronoa's magic as Gravy wonders where they went.
Meanwhile, a battered and bruised Goku: Xeno stands off against Xeno Majin Buu with numerous beings and a spaceship surrounding them.
Dark Demon God Buu
Majin Buu absorbs Demon God Dabura: Xeno
Goku: Xeno faces off against Xeno Majin Buu having now merged with the Three-Star Dark Dragon Ball in battle. As the Dark Empire Forces surround them on all sides, Demon God Dabura: Xeno descends onto the battlefield and soon attacks Xeno Majin Buu with his objective to steal the dark Dragon Ball from him. Withdrawing a sword he slices Xeno Majin Buu in half before turning his attention towards Goku: Xeno who rushes in to attack him. However whilst Dabura: Xeno is preoccupied with Goku: Xeno, Xeno Majin Buu takes Dabura: Xeno by surprise and absorbs him, transforming him into the more powerful Demon God Buu.
Xeno Vegito fights with Demon God Xeno Majin Buu
The Dark Empire Forces rush at the newly formed Xeno Majin Buu but they along with their ships are quickly eradicated by Xeno Majin Buu before he turns his attention on Goku: Xeno. He attacks Goku: Xeno and appears to have the upper hand. Chronoa appears on the battlefield having transported both Xeno Trunks and Vegeta: Xeno along following their battle with Xeno Cell and Gravy. Xeno Trunks intercepts a blow from Xeno Majin Buu that was meant for Goku: Xeno then turns Super Saiyan in an attempt to hold buy the others some time. Chronoa removes her Potara earrings and gives them to Goku: Xeno and the reluctant Vegeta: Xeno which transforms them into Xeno Vegito.
Chamel blocks Xeno Vegito's Spirit Sword
Xeno Vegito immediately steps in between the battle involving Xeno Majin Buu and Xeno Trunks. Xeno Vegito and the empowered Xeno Majin Buu begin fighting where they prove to be a match for each other, exchanging blows on both sides. Xeno Vegito fires his Spirit Sword directly at Xeno Majin Buu but before it reaches him the attack is blocked by the sudden appearance of Chamel.
Meanwhile, in another Dimension, Turles: Xeno who has merged with the Four-Star Dark Dragon Ball encounters Salsa who has shown up alongside Mechikabura and the Dark-Masked King in order to recover his Dark Dragon Ball.
Advent of Mechikabura
Turles: Xeno undergoes a Dark Evolution
On the Sacred World of the Kai, the sudden appearance of a mysterious person has caused confusion. Irritated by the interference Xeno Majin Buu attacks him. At the Tree of Might, Mechikabura alongside Salsa and the Dark-Masked King stand opposite Turles: Xeno who has merged with the Four-Star Dark Dragon Ball and plan to retrieve it for their own purposes. On Mechikabura's order the Dark-Masked King steps forward and attacks Turles: Xeno, knocking him backward into the Tree where he then eats a piece of its fruit and gains a significant boost in power from it and causes him to undergo a Dark Evolution transformation.
Salsa attacks Turles: Xeno
Digging his hand into the ground he tosses a large rock towards Mechikabura and Salsa with the latter using his sword to cut the rock into pieces. He gets behind Turles: Xeno and lands a kick to the nape of his neck but Turles: Xeno remains unharmed much to Salsa's surprise. Turles: Xeno kicks him back towards Mechikabura who asks Salsa what he thinks of his opponent to which Salsa tells him that Turles: Xeno's strength is on par with or even greater than that of a Demon God. Impressed Mechikabura says that once all seven of the Dark Dragon Balls are recovered it will be enough to fully restore him. Turles: Xeno charges towards the pair but Mechikabura raises his hand and fires a Ki blast that levels the surrounding area, destroying both the Tree of Might and presumably Turles: Xeno along with it. Recovering the Four-Star Dark Dragon Ball he turns and begins to leave, their mission a success but not before telling the Dark-Masked King that the power he put forth was not good enough.
Chamel appears before the others
Back at the Sacred World of the Kai, Xeno Vegito has now diffused back into Goku: Xeno and Vegeta: Xeno. Chronoa starts to panic over Xeno Majin Buu and the other warrior having escaped and Goku: Xeno tells them he can no longer feel their ki and presumes that they are no longer in that time period.
The foe suddenly appears before them all, unscathed from the earlier attack from Xeno Majin Buu and Xeno Trunks readies himself for an attack but the Supreme Kai stops him and asks what his scheme is. The foe says that there is no scheme and that they are useful to have around, saying he doesn't expect or need their trust before hinting that Hell is becoming agitated.
Towa and Shroom in Hell
Chronoa uses a spell to transfer Goku: Xeno and Vegeta: Xeno's injuries on to herself so that they along with Chamel can continue their pursuit of Xeno Majin Buu who has fled to Hell.
Xeno Janemba
In a version of Age 774, Towa who has appeared in Hell along with the Grim Reaper Shroom to retrieve the Five-Star Dark Dragon Ball from Xeno Janemba easily defeats that timelines Goku.
Xeno Janemba powers up in a new form
Shroom calls upon a Grim Reaper Soldier who appears from a portal in the ground and attacks Xeno Janemba. When Xeno Janemba attempts to retaliate with a kick, the soldier grabs a hold of his leg. Shroom then uses his Scythe to cut through the two of them in one swipe. Xeno Janemba however rematerializes gaining more power than before due to the Dark Dragon Ball.
This time, Shroom goes in for the attack personally and while at first Xeno Janemba is able to put up a decent fight he is ultimately cut in half again and the Dark Dragon Ball falls to the ground.
However, before Towa can retrieve the ball, Goku: Xeno, Vegeta: Xeno, and Chamel show up in front of them. Chamel vows to destroy Towa and Shroom with Towa commenting that Chamel had betrayed them after all. Chamel tells Goku: Xeno and Vegeta: Xeno to attack Shroom while he deals with Towa and they all begin to battle.
Super Xeno Gogeta
Suddenly the Dark Demon God Xeno Majin Buu who still has the Three-Star Dark Dragon Ball merged appears and using a detached part of his body absorbs Xeno Janemba to undergo another transformation.
Meanwhile, Goku: Xeno and Vegeta: Xeno struggle against Shroom as they have little strength after having their souls mowed, one of Shroom's special abilities.
With little other choice, Goku: Xeno and Vegeta: Xeno use the Fusion Dance to become Xeno Gogeta and transform into a Super Saiyan before urging Shroom to fight him again.
Meanwhile, at the Time Nest, Chronoa having recovered from her injuries and having a good rest claims that she now has the energy back that is needed to summon a new helper.
Super Namekian
Xeno Slug towers over Gohan and Xeno Trunks
Gohan: Xeno and Xeno Trunks travel back through time in order to find the source of the disturbance that has altered the timeline, the Dark Dragon Ball. They are suddenly attacked from behind by Xeno Slug who having used his Great Namekian form has grown to the size of a building. Gohan: Xeno and Xeno Trunks narrowly avoid the blast and notice that Xeno Slug has merged with the Six-Star Dark Dragon Ball.
Dark Demon God Xeno Majin Buu appears
Gohan: Xeno asks Xeno Trunks to stand back and let him take on Xeno Slug himself and begins whistling which harms Xeno Slug due to his highly sensitive hearing. Open to attack, Xeno Trunks prepares an attack in order to retrieve the Dark Dragon Ball but before he can, numerous portals open up around Xeno Slug. The Dark Demon God Xeno Majin Buu having recently absorbed Xeno Janemba begins attacking Xeno Slug. As Gohan: Xeno and Xeno Trunks comment on the surprise appearance of Xeno Majin Buu, they are joined by another, Towa who has also come to retrieve the Dark Dragon Ball for herself having already obtained two others just recently.
Lord Slug undergoes a Dark Evolution
Chamel having followed Towa also appears and sides with Gohan: Xeno and Xeno Trunks. Towa acknowledging the difficulty of the situation she is in, uses her magic to cause Xeno Slug to undergo a Dark Evolution causing his size to multiply even further. Towa, happy with how events are now playing out voices that she is happy that she studied Putine's powers in order to be able to control darkness and prepares herself to retrieve the Dark Dragon Balls from Xeno Slug and Xeno Majin Buu whilst also recovering her brother Dabura: Xeno.
Gohanks: Xeno
Xeno Slug attacks Gohan: Xeno, Xeno Trunks, and Chamel but the attack does no damage thanks to Chamel creating a protective barrier in the nick of time. Gohan: Xeno suggests that Xeno Trunks merge with him to which he agrees and the two perform the Fusion Dance to become Gohanks: Xeno who immediately goes on the offensive due to them only having 30 minutes before they defuse. However, Gohanks: Xeno is unable to do any damage to Xeno Slug due to his overwhelming size.
Meanwhile, Towa battles Xeno Majin Buu until she is suddenly attacked from below by Chamel. The attack causes Towa to drop her guard and Xeno Majin Buu goes in for the kill but is intercepted by the appearance of Salsa who has also brought along Turles: Xeno who promptly kicks Chamel away. Towa asks Salsa why he has shown up to which he responds that he has no honor left after shaming Mechikabura previously.
Salsa says that his power as a Demon God has adapted to his body better than it had before and with his new found might, eradicates the bodies of Xeno Majin Buu and Xeno Slug with his Trick of Tornado which causes the Dark Dragon Balls to become loose and Dabura: Xeno to return. Towa recovers the Dark Dragon Balls and her brother and then teleports away much to Chamel's frustration.
In the Demon Realm, Gravy and Putine report to Mechikabura that Towa and the others have successfully recovered three of the Dark Dragon Balls and Dabura: Xeno. Please, Mechikabura tells them to inform Towa to see him when she returns and to also bring a mask which is used to be used for their chained prisoner, Dark Broly who has merged with the Seven-Star Dark Dragon Ball.
In Hell, the battle between Super Saiyan Xeno Gogeta and Demon God Shroom rages on with neither having a clear advantage. When a dark portal opens up above the two, the time limit for Goku: Xeno and Vegeta: Xeno's Fusion runs out. When Goku: Xeno flies off to head through the portal, Shroom attempts to stop him but Vegeta: Xeno intervenes by grabbing his Scythe, allowing Goku: Xeno to get away while Vegeta: Xeno faces off against Shroom alone.
Dark Broly
Dark Broly
In the Demon Realm, Towa and Xeno Paragus attempt to defend themselves from an out of control masked Dark Broly who is using the Super Saiyan 4 transformation and also merged with the Seven Star Dark Dragon Ball but find themselves completely outmatched. Meanwhile Mechikabura watches on in amusement from above on his throne with Xeno King Vegeta, Gravy, Putine, and Salsa standing alongside him. Goku: Xeno then appears, having come through the other side of the portal and upon seeing him, Dark Broly goes into a fit of rage and attacks Goku: Xeno immediately, Towa and Xeno Paragus take the opportunity to attack Dark Broly but Xeno Paragus is punched hard, knocking him through the same portal that Goku travelled through. Dark Broly then turns his sights once again on Goku knocking him to the ground hard with a punch, Towa fires a blast at him from out of her staff which hits him the back. Dark Broly turns around and hits Towa hard enough to send her crashing into a nearby wall where she then falls out of her Demon God form and back into her Base form.
Mira after absorbing Towa
Suddenly Mira in his Berserk form appears having also travelled through a dark portal which shocks both Salsa and Putine who thought that he had been killed earlier by Xeno Trunks. Mira turns to face the now unconscious Towa and absorbs her which allows him to undergo a new and more powerful transformation and when Dark Broly rushes in to attack him, Mira is easily able to stop his attack with his palm.
Goku: Xeno, Dark Broly, and Mira about to fight
Seeing the ongoing battle between the two, Goku: Xeno powers up into his Super Saiyan 4 state as well and heads into battle as all three fighters battle it out against one another at the same time. The three prove to all be on par with each other and end the battle each with a large beam of energy causing a huge explosion that knocks out Goku: Xeno and Dark Broly, causing his Dark Dragon Ball to fall out of his chest. Mira is the only one left standing, battered and bruised, now having released Towa from his body, he now holds both her and the Dark Dragon Ball in his arms.
Mechikabura Revival
Bardock: Xeno arrives on an asteroid and sees a broken Time Breaker mask on the ground, noting he came because he sensed something and wonders if Towa and Mira are up to something again.
Xeno Paragus, who had been flung through a wormhole by Dark Broly, arrives and is encountered by the Dark-Masked King who had been sent to recover him, however Xeno Paragus's Time Breaker eyepatch had broken and so he was no longer under control, he fights back against the Dark-Masked King but is easily overwhelmed.
Super Saiyan 3 Bardock: Xeno
Bardock: Xeno saves Xeno Paragus and calls the Dark-Masked King weak for not having broken out of the mind control like Bardock: Xeno had in the past. However the masked king suddenly does, revealing that he is Xeno King Vegeta and that he had allowed himself to be mind controlled in order to gain the power and now he has gained control of the darkness. He then reveals his intentions to go back in time to before the Genocide of the Saiyans to eliminate Frieza and Beerus and asks Bardock: Xeno and Xeno Paragus to rejoin him.
Bardock: Xeno acknowledges the difference in strength between the two of them but still he refuses, finding the notion of changing history worthless and that they must accept the past. He picks up his broken mask, putting it back on in order to become stronger due to the darkness but this time he is able to resist and uses the power as his own to transform into a Super Saiyan 3. As they fight, Xeno Paragus stabs Xeno King Vegeta in the side, but is in turn obliterated by the Saiyan king.
Super Saiyan 3 Bardock: Xeno and Xeno King Vegeta then fire two huge energy waves at each other creating a mighty explosion. Meanwhile, in the Demon Realm, the Dark Dragon Balls have all been gathered and Mechikabura is preparing for his wish.
In Hell, Vegeta: Xeno continues his battle against the Demon God, Shroom. As Shroom goes in to finish off the worn out Vegeta: Xeno, he is suddenly attacked by Gotenks: Xeno who appears through a dark portal followed by Chronoa, Chamel, and Gohan: Xeno. Outnumbered, Shroom retreats through the same portal back to the Demon Realm. Chronoa uses her magic abilities to temporarily rewind Vegeta's injuries and meanwhile notices that the dark portal is beginning to close and asks Chamel to use his magic to open it back up so they can enter through it.
Vegeta: Xeno turns into a Super Saiyan 4
In the Demon Realm, Mechikabura thanks his subordinates, Gravy, Putine, Towa, Salsa, Mira, Dabura: Xeno, and his Demon Realm Soldiers for having finally gathered together all seven of the Dark Dragon Balls and summons the Dragon known as Dark Shenron. The others soon sense a large formation of Ki and realize that the Time Patrol, now also with Goku: Xeno, have come to the Demon Realm. Not wanting the Time Patrol to intervene, the soldiers swarm the group but the combination of Gotenks: Xeno and Vegeta: Xeno, no longer restricted from using Super Saiyan 4 due to their location in Demon Realm, quickly overwhelm their forces. Chamel soon steps in, transforming into his Demon God form and uses his magic to suck all the soldiers in through a portal and to an unknown location on the other side.
Most of the forces are wiped out but Towa says it's too late anyway as Dark Shenron suddenly emerges and Mechikabura asks the Dragon to give him the strength that he once had in his peak. However Dark Shenron states that due to Mechikabura having such a large quantity of power, it will take him some time to restore it all. Chronoa spotting the Dragon urges the rest of the Time Patrol to hurry and stop them before the wish is granted.
The members of Chronoa's Time Patrol face off against Mechikabura's Demon God subordinates as Chronoa attempts to head directly to Mechikabura and Dark Shenron but she is halted by Dabura: Xeno who gets in her way. Gotenks: Xeno suddenly appears and hits Dabura but then immediately defuses back into Goten: Xeno and Xeno Trunks, their time having run out. Goten: Xeno holds off Dabura: Xeno as he tells Xeno Trunks to go on ahead with Chronoa.
Super Saiyan 4 Xeno Gogeta
Meanwhile, Vegeta: Xeno battles Gravy but finds that his previous injuries have already returned. Goku: Xeno too, is struggling due to being low on energy from his recent battle with Mira and Dark Broly and so with little other choice the two fuse together into Super Saiyan 4 Xeno Gogeta thanks to the help of Chamel buying them some time by trapping their adversaries in barriers. Chamel realizes that his secret plan to steal the Dark Dragon Balls has now ended in failure but hopes for the Time Patrol to stop Mechikabura from reaching his previous power.
Chronoa, due to help from Xeno Trunks is able to reach Mechikabura who has now regressed in age, back to his youth and has gained back his previous power. In response, Chronoa releases all the power that she has collected and undergoes a new transformation and uses her powers to transport both herself and Mechikabura out of the flow of time entirely.
Demigra returns
Suddenly the other members of the Time Patrol return to the Time Nest, confused as to what had just happened. Xeno Trunks notices that the Demon Realm in it's entirety has disappeared after looking at one of the time scrolls. In another location, Chamel is shown kneeling before Demigra who says that it is time for them to make their move. Back at the Time Nest, Xeno Trunks hands over time crystals to the others that had been given to him at an earlier time by Chronoa and explains that they are needed in order to visit other eras. The Time Patrol then vow to go and save Chronoa.
