Alternate Timeline

Several alternate timelines are shown to exist in the Dragon Ball manga and the Dragon Ball Z as well as the Dragon Ball Super manga and anime series. Shown below are the specific timelines and their specific events. A number beside a character's name indicates which dimension (what timeline) they are from; if there is no number beside the character's name, that means that they are from the dimension (timeline) the description is under. There are a total of 5 timelines, and 4 of them are alternate timelines.

Time Machine generated timelines

The alternate timelines were all created and linked due to the use of a Time Machine. Because the Future Android 17 and Future Android 18 killed the Z Fighters and most of the potential heroes of Earth, Future Bulma created a Time Machine to send her son Future Trunks to the past to prevent Goku from dying of a Heart Virus, to warn the Z Fighters about the future android threat, and to find a way to stop the androids in the future world (either a way to deactivate the androids or a way to destroy them, maybe even taking Goku to Future Trunks' timeline).

It should be noted that, in the universe of Dragon Ball, one does not have to directly interfere with a timeline to disrupt it. Simply going back in time causes disruptions to the timeline as various random changes occur. For example, Androids 19 and 20 came first, despite no explanation occurring for why they would exist, and Androids 17 and 18 are also inexplicably stronger than Future Trunks remembers. Therefore, even if a time traveler follows a "look but don't touch" policy, they risk changing history.

Timeline 1 is where the main story takes place, and Future Trunks and Cell arrive there from their respective future. Timeline 2 is the original timeline from where Future Trunks originates. Timeline 3 is where Cell originates from and goes back in time by killing Trunks and stealing his Time Machine; this timeline is briefly seen. Timeline 4 is never seen, but it is the timeline in which the Trunks from Cell's original timeline (3) goes back in time to find a mean to destroy the androids. Timeline 5 has to be where the Trunks that Cell³ said killed Timeline 3's Frieza and King Cold originated from.

In Dragon Ball: Xenoverse, it is explained that Bulma's Time Machine had an unknown flaw in its design that generated time distortions which lead to the creation of alternate timelines, thus some of random changes in these timelines where the direct result of the using the Time Machine itself. It is also explained that with help from the Supreme Kai of Time (the God of Creation that governs time), Future Trunks modified the design of his mother's time machine to create new Time Machines that lack this design flaw and do not produce alternate timelines, thus making them safe for use the Time Patrol. It is also explained that due to the Supreme Kai of Time's benevolence she chose not to erase the timelines created from Future Trunks' and Cell's use of the Time Machine, as things turned out for the better and because she understood Trunks' and his mother's reasons were noble and ultimately for the greater good.

Timeline 1: Main

Gohan kills Cell in the main timeline

This is the main timeline in which the Dragon Ball series takes place and ultimately leads to Dragon Ball Super, the end of Dragon Ball Z and Dragon Ball GT. It is possible that timeline 4 also leads to a similar arc, one where Goku never died in the first place. There are two time/dimensional travelers who interfere with this timeline: Future Trunks from timeline 2 and Cell from timeline 3.

Cell³'s travel to the past and Future Trunks'² trip to the past create this timeline, which "replaces" timeline 4.

• Cell³ arrives from the future from the Time Machine he stole from Future Trunks³ in an egg form because he could not fit. He hatches and burrows underground to develop.
• Frieza and King Cold invade Earth to get revenge on Goku, and to also destroy the planet. They are killed by Future Trunks² who appears from the future. Future Trunks² then meets Goku when he arrives on the planet and gives him the Heart Medicine, from 20 years in the future; he also warns the Z Fighters about the Red Ribbon Androids who will arrive in three years, before returning to his timeline.
• In the next three years, the Z Fighters go into intense training, and Trunks¹ is born to Vegeta and Bulma as their first child.
• Dr. Gero (aka Android 20) and Android 19 battle the Z Fighters. Goku, who did not take Trunks' medicine/antidote, becomes sick during his fight with Android 19. Vegeta arrives and takes over, destroying 19, and Goku is taken home and given his medicine. Dr. Gero flees.
• Future Trunks² arrives back to this timeline and finds the destroyed Android 19, a robot he has never seen before. He begins to realize that this timeline is starting to branch off considerably from his.
• Dr. Gero escapes back to his lab and awakens Android 17 and Android 18 who then proceed to kill him. They go on to activate Android 16.
• The Z Fighters are defeated by 17 and 18, but none are killed.
• Future Trunks³' Time Machine from timeline 3 (used by Cell³) is found, along with Cell's shed skin.
• Cell³, now fully grown, starts razing cities and absorbing the people to raise his power.
• Piccolo fuses with Kami and battles against Cell³. Cell tells Piccolo about who he is, why he is here, and how he got to this timeline. Cell escapes after Future Trunks² and Krillin arrive on the scene to aid Piccolo.
• Piccolo hunts for Cell³ while Future Trunks² and Krillin go to Gero's underground lab to destroy Present Cell¹ while he is still gestating. While there, Future Trunks² finds blueprints for the androids which he gives to Krillin to take to Bulma.
• To become stronger, Vegeta and Future Trunks² train in the Hyperbolic Time Chamber.
• Piccolo, unable to find Cell, is confronted by the androids. He decides to attempt to destroy them in order to prevent Cell from absorbing them and becoming stronger.
• During Piccolo's battle against Android 17, Bulma contacts Krillin telling him that she is created an emergency shutdown device based on Gero's blueprints. It has a range of 10 meters so Krillin rushes to intercept her and obtain the control device to deactivate and destroy the androids. Cell³ detects Piccolo's raised ki and deduces that he is battling an android; Cell rushes to the scene to absorb the androids and complete his development.
• Cell³ interrupts Piccolo and 17's fight, quickly dispatching Piccolo and nearly absorbing 17 before Android 16 intervenes. Cell and 16 fight relatively evenly, but in the end Cell manages a surprise attack that allows him to absorb 17 and become Semi-Perfect Cell. Cell proceeds to easily deal critical damage to Android 16 and is going to absorb 18 but is halted temporarily by Tien Shinhan, allowing 16 and 18 to escape. Goku quickly arrives on the scene and rescues Piccolo and Tien before retreating again.
• Vegeta and Future Trunks² emerge from the Hyperbolic Time Chamber, letting Goku and Gohan enter. Vegeta battles against Cell and is clearly dominant in the fight. While they are fighting Krillin approaches Android 18 with the shutdown device, but is captivated by the beautiful android and destroys the remote. Vegeta quickly becomes arrogant with his power and gives Cell leave to absorb 18 to attain his perfect form.
• Cell finds 18 and finally absorbs her, becoming Perfect Cell; he then goes on to defeat Vegeta and Trunks. Cell decides to hold a tournament, the Cell Games, in ten days to test his new abilities.
• Goku and Gohan emerge from the Hyperbolic Time Chamber. Trunks, Vegeta and Piccolo all use the room before the tournament starts. Goku recruits Dende to serve as the Earth's new guardian and reactivate the Dragon Balls.
• The Cell Games start and Goku fights with Perfect Cell. Goku eventually forfeits the match and chooses his son Gohan fight instead.
• Gohan fights Perfect Cell and, after eventually being provoked into transforming into the Super Saiyan 2 stage, delivers a fierce set of hits to Cell, causing him to regurgitate Android 18 and transform back into his Semi-Perfect state.
• Semi-Perfect Cell attempts to destroy the Earth by self-destruction, but Goku sacrifices himself to teleport Semi-Perfect Cell from the Earth to King Kai's planet. Cell explodes, killing Goku and King Kai. Cell's regenerative organ miraculously remains intact, allowing him to fully heal his entire frame. Cell returns to Earth, stronger than ever and kills Future Trunks², but is defeated for good by Gohan.
• Future Trunks² is revived by a wish made to Shenron, and returns to his timeline.
• The rest of the history of Dragon Ball Z and later Dragon Ball Super occur.

Unaltered Timestream

• In the original unaltered flow of time, at some point after the tournament with Universe 6, Goku fights Zamasu¹ and defeats him, which enhances Zamasu's hatred for mortals.
• Zamasu kills Gowasu and steals his Time Ring. He then uses the Super Dragon Balls to switch bodies with Goku and becomes Goku Black.
• Black then kills Goku (in Zamasu's body), Goten and Chi-Chi, and eventually travels to Timeline 2 for initiating his Zero Humans Plan (which leads to a series of events and results in the alteration of this time stream and creates an altered time stream).
  • These events are erased from having ever happened when Beerus annihilates Zamasu, because when a god kills another god, the timeline is affected, meaning Goku Black is never created.
    • However, Goku Black still remains unaffected despite his past self being killed, thanks to the Time Ring, which he obtained in the original unaltered flow of time.

Altered Timestream

• Following the events of the Universe 6 Saga, Future Trunks returns to the past to seek help from the Z Fighters after the Zamasu from the original unaltered flow of timeline 1 (Goku Black), arrives and begins slaughtering countless innocent people and thrusting the world into destruction in Future Trunks' timeline. Future Trunks' unnatural arrival via Time Machine causes the main timeline's future to alter off it's set path, eventually resulting in Zamasu's death at Beerus' hand before he can become Goku Black, but the Zamasu (Goku Black) from the original unaltered flow of Timeline 1 still remains unaffected.
• Future Trunks, Goku, and Vegeta travel to the future several times to confront Goku Black and Future Zamasu. They are forced to retreat on two occasions to formulate a better plan of attack.
• The Peaceful World Saga occurs several years later.
• The events of Dragon Ball GT happen in Age 789 through Age 790 and ends in Age 889.
• The events depicted in the "Xeno" period of time occur.

Timeline 2: Future Trunks

Future Trunks' timeline before he travels to the past

This is the timeline belonging to Future Trunks and depicted in a few chapters of the manga. This is the timeline in which any version of Future Trunks did not visit the present timeline. The first part of this timeline, common to timeline 3, is also depicted in the TV special Dragon Ball Z: The History of Trunks. In this one, Future Trunks goes back in time to the main timeline (1) and returns with enough power to kill both the Androids and Future Cell. This timeline can be seen as the "improved" version of timeline 3, which was the "first version" of the timeline for Future Trunks³. Thanks to Cell³'s trip to the past in timeline 3, this timeline and timeline 1 were created. In order to defeat Cell³ in timeline 1, Future Trunks trained in the Hyperbolic Time Chamber and increased his power. Thanks to his new power, he was able to destroy the Cell from timeline 2 when he came back. In Dragon Ball: Xenoverse, it is implied that before Trunks' use of his mother's time machine, there was only a single timeline: the nightmarish Future Trunks and his mother lived in, but his use of the Time Machine lead to the first time distortion in the history of the universe which lead to the creation of alternate timelines. In this timeline, there were no "time travelers" except for one, Zamasu¹ from the original timeline (known in this timeline as "Goku Black".)

• Frieza and King Cold invade Earth and are defeated by Goku.
• Trunks is born, Goku dies from Heart Virus.
• Dr. Gero activates Android 17 and Android 18. They kill him and then proceed to kill all of the other Z Fighters except for Gohan. The Dragon Balls permanently disappear, after Piccolo's death.
• Gohan becomes a Super Saiyan.
• Over the course of 13 years Gohan challenges the androids alone but never wins.
• Gohan trains Trunks, but after losing an arm is later killed by the androids. Trunks attempts to avenge Gohan but is badly beaten.
• Bulma builds a Time Machine to send Trunks to the past with the hopes of finding a way to destroy the androids. Trunks takes medicine to cure Goku's¹ heart condition with him.
• Trunks goes back in time to timeline¹. He returns after killing Frieza¹, giving Goku the medicine, and warning the Z Fighters about the androids.
• Trunks goes back in time again to help the Z Fighters in timeline¹ to combat the androids, and later Cell³.

The city rebuilt after the destruction of 18 and 17

• Trunks returns from timeline¹ more powerful as a result of his battles and training. He quickly finds and kills Androids 17 and 18 with little effort.
• Trunks kills the newly emerged Cell², knowing about Cell's plan to kill him and go back in time (see timeline 3).
• Earth slowly rebuilds its cities as peace comes to its inhabitants.
• An unknown amount of time after Future Cell and the Future Androids are destroyed, Future Supreme Kai arrives and begins to train Future Trunks, causing Trunks to grow not only into a Super Saiyan 2, but grow considerably in power and gain a new sword.
• Sometime after the fall of the Androids and Cell, Future Dabura and Future Babidi arrive with the hopes of reviving Future Majin Buu. Future Trunks intervenes and engages Dabura in combat and easily overpowers Dabura as a Super Saiyan, and kills both Babidi and Dabura in one giant blast, effectively eliminating Majin Buu's revival.
• Eight to nine years pass, after the fall of the Androids and Cell, Zamasu from the original unaltered Timeline 1 (who has now become Goku Black), uses the Time Ring to come to Timeline 2 and then begins his Zero Humans Plan after killing Gowasu² and allying with Zamasu^2.
• Goku Black and Future Zamasu then use the Super Dragon Balls to make Future Zamasu immortal and then a year later for the Super Dragon Balls to be destroyed.
• Black then invades the Earth and kills most of the population, calling it "justice." Having previously destroyed numerous other planets prior, along with the Supreme Kais. Future Trunks engages the new threat but is easy overpowered and beaten, despite his greatly increased strength.
  • Due to the death of the Supreme Kais, the God of Destruction of each universe has also died, and their angels (their attendants) become inactive.
• Future Bulma Suggests going back in time to get Goku and Vegeta and having them come into the future to assist and begins gathering fuel for a complete trip through time.
• 18 months later Bulma has enough fuel for a one way trip. However Black appears and attacks, with Trunks unable to sense his ki. Future Bulma tells Future Trunks to take what is left of the Fuel and go. Black murders Bulma with a point blank range Ki Blast and Trunks flee's to Future Mai and the time machine. Black attacks again and Future Trunks is once again overwhelmed. Future Mai attempts to help Trunks but is easily knocked unconscious (originally presumed to be killed) by Black. Enraged Trunks powers up to Super Saiyan and attacks and is able to catch Black off guard and deal some damage but even though able to hold his own, eventually beaten but manages to escape with a Masenko.
• Future Trunks gets away and uses the time machine to go back into the past. Black enraged tries to located him and his Time Ring activates and takes him to timeline 1 where he comes face to face with Future Trunks and the Z-Fighters.
• After the fierce battles with the Z Fighters, Black's Time Ring brings him back to this timeline where Black moves to attacking the base of the resistance formed by the Earthlings, who struggle to defend it from him.
• Future Trunks returns to this timeline along with Goku and Vegeta and they begin to fight against Black.
• Black overwhelms Vegeta and Goku with his Super Saiyan Rose form and is later aided by Future Zamasu (Zamasu²).
• Black fights Goku while Future Zamasu fights Future Trunks. The two incarnations of Zamasu succeed in defeating the Saiyan trio, which forces them to escape to Timeline 1.
• The Saiyan trio eventually return to Timeline 2 (this time with Bulma accompanying them), where they are defeated again. But due to the corrupt duo's words, Future Trunks grew angry and tapped into his power, gaining a new transformation. In this form, Future Trunks fought the pair by himself as Goku, Vegeta and Bulma return to Timeline 1 to figure out a plan.
• Goku, Vegeta and Bulma return to Timeline 2 (Goku having learned the Evil Containment Wave, Vegeta having trained in the Hyperbolic Time Chamber) for a rematch, with the resolve to seal the corrupt duo in an urn. Goku Black immediately destroys the time machine, which Bulma resolves to fix. Vegeta is now able to push back Goku Black thanks to his increased strength.

Timeline 3: Cell

This timeline follows a similar path to timeline 1 and timeline 2, it notably changes on Future Trunks' second return from the past as in this timeline, Future Trunks returned with the android blueprints from timeline 4, not the massive power increase from timeline 1. The androids were destroyed, but Trunks was not powerful enough to combat Cell. Cell killed Future Trunks and used his Time Machine to go back in time to find the androids, creating timelines 1 and 2.

This is the darkest timeline, as even Trunks is deceased.

• Frieza and King Cold invade Earth and are defeated by Trunks⁵.
• Trunks is born, Goku dies from heart disease.
• Dr. Gero activates Android 17 and Android 18. They kill him and then proceed to kill all of the other Z Fighters except for Gohan. Gohan becomes a Super Saiyan.
• Over the course of 13 years Gohan challenges the androids alone but never wins.
• Gohan trains Trunks, but is eventually killed by the androids. Trunks attempts to avenge Gohan but is badly beaten.
• Bulma builds a Time Machine to send Trunks to the past with the hopes of finding a way to destroy the androids. Trunks takes medicine to cure Goku's⁴ heart condition with him.
• Trunks goes back in time to timeline 4 (which is created because of this trip). He returns after killing Frieza⁴, giving Goku⁴ the medicine, and warning the Z Fighters⁴ about the Red Ribbon Androids.
• Trunks goes back in time again to help the Z Fighters⁴ in timeline 4 to combat the androids.

Cell strangles and kills Trunks in his timeline

• Trunks returns from the past and destroys the androids after using their emergency stop circuit.
• Cell emerges and, realizing the androids are gone, decides to use Trunks' Time Machine to go back in time and find the androids in the past. Cell ambushes and kills Trunks, gets the Time Machine and goes to Age 763¹. This eventually creates timeline 1 and 2. In timeline 1, Cell is ultimately destroyed by Super Saiyan 2 Gohan¹ with a Father-Son Kamehameha.
• Even though Trunks died in this timeline, both Cell and the androids are gone, so Earth presumably starts to rebuild itself.

Timeline 4: Unseen

Little information is given about this timeline, which comes from Daizenshuu 7. This timeline is not addressed in later guidebooks.

• The Cell Games happen, but Trunks is absent.
  • The absence of Trunks may happen due to having been killed by Cell in Timeline 3.

Timeline 5: Unknown

Nothing is known about this timeline, other than that an incarnation of Trunks existed in it.

The Trunks who existed in this timeline visited Timeline 3 (Cell's timeline) in order to defeat Future Frieza and Future King Cold. He presumably never returned to Timeline 3 after heading back to Timeline 5 and the Z Fighters there were killed by that timeline's Androids, or he may have returned only to die alongside them fighting the Androids.

Trivia

• Cell³ traveled back in time to Age 763, according to him, because that was the year that was programmed on the machine. But if Future Trunks³ story is similar to Future Trunks² story, he was about to use the machine to tell the Z Fighters from timeline 4 that he had defeated the androids in his universe. However, there is no reason for Future Trunks³ to go to Age 763 to do that; nobody knew him at that time, since his first trip was to Age 764. (This might only be explained by the inaccuracy of the time machine.)
• It is explained by Gowasu that a green Time Ring appears when an alternate timeline is created. With four green Time Rings being shown aside from the main silver Time Ring for their own timeline, it is known that there are five different timelines.
• The first alternate timeline was created by a time machine utilized by a mortal from an advanced civilization in Universe 12.
