How would you fit the DBZ era movies to into the timeline?

[AvatarReiko]

Looking back at all the movies, it's pretty safe to say that none of them bar Movie 13 and maaaaybe Bojack Unbound could fit in the timeline without huge inconsistencies. If you were to try and reconcile these movies so that they fit consistently into the timeline. How would you do that and what would events/things would you change so that they fit?

For clarification, we're talking about movies DBZ movies 1-13

[theherodjl]

They don't fit, they're described as an "alternate dimension" by Akira Toriyama for this very reason. Not any of the established parallel universes/timelines but an outside continuity of side stories, similar to DC Comics' "Elseworlds" stories which has no bearing at all on the main universe or timeline's events.
The intention of the movies is to serve as glorified filler while the manga & anime are in a brief recess of development.

Just off the top of my head...

Movie 01 - Gokū and Piccolo manage to kill Raditz without either of them dying, so the Dragon Balls are never made known to Vegeta and Nappa.
Movie 02 - Gokū arrives before any of his friends get killed and Kurilin kills Vegeta before he can escape, so a trip to Namek never happens.
Movie 03 - Movie 02 happens and Kurilin never learns of the Namekian Dragon Balls and all their friends live, so a trip to Namek never happens.
Movie 04 - Movies 02 and 03 happen and Freeza never learns of the Dragon Balls in any capacity, so he doesn't take a trip to Namek either.
Movie 05 - Gokū manages to kill Freeza with the Genki Dama without becoming a Super Saiyajin and everyone returns to Earth together.
Movie 06 - Movie 05 happens and No. 18 and No. 17 are disabled via a remote control device built by Bulma based on Dr. Gero's blueprints.
Movie 07 - Movies 05 and 06 happen and Cell is most likely killed by Gokū, Vegeta, and Trunks since there are no No. 17 or No. 18 to absorb.
Movie 08 - Movies 05, 06, and 07 happen OR Vegeta successfully kills Cell in his Second Form. Either one would work equally well, I believe.
Plan to Eradicate the Saiyajin - Movie 08 happens and only part of the anime continuity due to the specifics of the Saiyajin-Tsufurujin War.
Movie 09 - Only part of the anime continuity due to the presence of Sky Dragon from the Dragon Ball filler. Trunks' hair might be inconsistent.
Movie 10 - Movie 08 happens and Gohan, Trunks, and Goten take a break from their training for the 25th Tenkaichi Budōkai. Where's Vegeta?
Movie 11 - Movies 08 and 10 happen and SSJ3 Gokū kills Boo. Only part of the anime continuity due to the presence of Other World filler.
Movie 12 - SSJ1 Gotenks manages to kill Boo, so Gokū and Vegeta remain dead. Only part of the anime continuity due to Other World filler.
Movie 13 - Only part of the continuity if Trunks decides to keep and continue using Tapion's Sword. May or may not lead up to Dragon Ball GT.

[Grimlock]

it's pretty safe to say that none of them bar Movie 13 and maaaaybe Bojack Unbound could fit in the timeline without huge inconsistencies.

Movie 13 does not fit at all if you consider Toei's continuity of Dragon Ball Super.

Super could easily take place after the events of movie 13

[KBABZ]

I'm with theherodjl on this one: to fit all the movies together would almost certainly mean that you'd have to concoct a new timeline of the manga/anime that leads to each film occurring, since almost all of them are incompatible with the one we're familiar with.

[Grimlock]

Super could easily take place after the events of movie 13

Not only Dragon Ball Super does take place after Movie 13, as this is precisely why Movie 13 does not fit though.

[Analytical Delusion]

Movie 1 - Knowledge issue (Kuririn and others hadn't seen Goku in years, didn't know Gohan). Alternate timeline in which Raditz is killed and Goku survives.
Movie 2 - Impossible (everyone alive in Saiyan/Freeza era incarnations). Alternate timeline in which nobody dies to the Saiyans, or Freeza isn't on Namek.
Movie 3 - Same as Movie 2.
Movie 4 - Out of character/awkward fit (Goku doesn't have Super Saiyan mastered). Alternate timeline in which Goku kills Freeza on Namek and returns with everyone else.
Movie 5 - Same as Movie 4.
Movie 6 - Out of character/awkward fit (Dende is guardian, Earth at peace). Alternate timeline in which the Androids & Cell are killed before Goku/Gohan enter RoSaT.
Movie 7 - Same as Movie 6.
Movie 8 - Out of character/awkward fit (Goku & Gohan not Super Saiyans while Gohan aged post-RoSaT, Earth at peace). Alternate timeline in which Goku survives the Cell Games.
Movie 9 - Fits fine.
Movie 10 - Knowledge issue (Videl knows about Super Saiyans). Alternate timeline in which 25th TB isn't interrupted.
Movie 11 - Impossible (Goku dead after 25th TB, Earth at peace). Alternate timeline in which 25th TB isn't interrupted.
Movie 12 - Impossible (Goku and Vegeta dead, Earth at peace). Alternate timeline in which Gotenks or Gohan defeats Buu.
Movie 13 - Fits fine.

Movie 13 - Fits fine.

I'm gonna try and use this to come up with what the movie timeline could be like!

• The Pilaf, 21st TB, Red Ribbon and 22nd TB arcs are replaced by DB movies 1-3 (although Movie 1 can be replaced by The Path to Power if you wish). Krillin is killed after the end of DB Movie 3 to ignite the King Piccolo arc and the 23rd TB arc after it. Between Movies 2 and 3, Goku and pals learn about fire and road safety.
• DBZ Movie 1 occurs. The reunion before Raditz still happens, but now there's no surprises about Gohan. Goku still dies to Raditz to learn the Kaio-Ken and the Genki-Dama from King Kai.
• Vegeta and Nappa do not arrive a month earlier than anticipated, allowing Goku to arrive more comfortably and for Movies 2 and 3 to take place before they show up.
• The Saiyan fight goes as normal despite Goku being there, prompting the trip to Namek to bring their friends back. Goku returns to Earth much earlier after learning Instant Transmission from the Yardratians (but not before the Garlic Jr. arc), and Movies 4 & 5 occur.
• Cell makes himself known some time after the Androids are defeated, giving a breather period where the Androids remain in hiding searching (unsuccessfully) for Goku. This allows for Movies 6, 7, 8 & 9 to go down. After this, Cell finally appears to track down 17 and 18, encounters the Z Warriors first, and the main arc resumes as before. Trunks has long hair because he's an unkempt boy.
• The arrival of Spopovic and co (as well as Supreme Kai) doesn't occur during the 25th TB and it goes as normal; Videl learns of Super Saiyans thanks to Trunks and Goten being exposed as Mighty Mask. Movie 10 occurs.
• Spopovic and co. now arrive after Movie 10 and drain Gohan to revive Buu. Buu is able to kill Goku, and Vegeta unsuccessfully sacrifices himself. Gotenks is able to kill Buu without messing around, meaning Goku and Vegeta no longer have to be revived to help. Movie 11, 12 and the Otherworld Tournament take place after.
• Goku and Vegeta are wished back to life with the Namekian Dragon Balls, allowing Movie 13 and Plan to Eradicate the (Super) Saiyans to occur.
• Lastly, GT, specifically the Super 17 arc, also occur due to the presence of movie villains. The Goku Jr. special also takes place 100 years after GT.

Since I have no familiarity with the movies this probably has a dozen plotholes, but I think it's cool regardless!

[ulisa]

This has always been my theory for it, multiple timelines

Timeline 1
The main timeline of the series-including the new specials and movies (Goku and his friends return!, Battle of the Gods/Resurrection of F) and into Super. This timeline also has Movie 9 (Bojack Unbound) and Movie 13 (Wrath of the Dragon) which fit into the canon timeline. Dragonball Minus occurs and not Bardock Father of Goku/Episode of Bardock

Timeline 2
Pretty much identical to Timeline 1 except Super does not happen and GT happens instead and Bardock Father of Goku/Episode of Bardock instead of Dragonball Minus

Timeline 3
Because Movie 1 (Dead Zone) occurs, Gohan's power is known prior to the Saiyan arc, resulting in him being trained a bit by Goku before Raditz, making him more capable during the fight with Nappa and Vegeta. This essentially saves Goku from getting as brutal of a beating, allowing him to travel with Bulma, Gohan, and Krillin to Namek. Because Goku and Freeza would be tough to deal with simultaneously, Vegeta teams up with them much earlier. This leads to Freeza being beaten in his first form. They revive their friends, and Movies 2 (World’s Strongest), 3(Tree of Might), and 4(Lord Slug) are able to happen.


Timeline 4
Goku doesn't linger in space after Namek, and never masters SSj transformation. Trunks comes back to tell of the Androids. This leads to Movie 5(Cooler’s Revenge), where he cannot transform at will. Seeing how helpless they were against a random invader who is supposed to be drastically inferior to the Androids, Piccolo and Kami agree to fuse in order to give them an extra edge. Piccolo here isn't as strong as he is in the main timeline, because he has less training with SSj Goku under his belt at the time of his fusion with Kami. This prompts bringing Dende to Earth to be the new Kami. The Big Gete Star nabs Coola, and Movie 6 (Return of Cooler) happens.

Timeline 5
Since Cell wasn't around, Kami wasn't convinced to fuse with Piccolo. The blueprints found in Gero's lab were used to build a controller, which shut down #17 and #18. Movie 7 (Super Android 13) stems from this.

Timeline 6
The "Vegeta doesn't ruin everyone's plans" timeline. He goes to finish off Semi-Perfect Cell, who escapes via Taiyoken and goes into hiding. Goku and Gohan leave the RoSaT early. Movie 8(Broly, the Legendary Super Saiyan) occurs, because Paragus, who was keeping a close eye on Earth, saw that things were safe. Afterwards, Cell sneakily nabs #18 and becomes Perfect, announces the Cell Games, etc. Seven years later, Movie 10 (Broly-Second Coming) happens while Gohan and co. train for the 25th TB. When The Saiyans are confronting Babidi, Vegeta stays patient long enough for Babidi and Dabura to be slain. He gets his rematch with Goku afterwards. Goku leaves. Later on, Movie 11(Bio-Broly) happens, because #18 still bribed Mr. Satan.

You could also make this into a “Goku doesn’t die from Cell Timeline though apparently something has to kill him before Bio Broky...

Timeline 7
Ultimate/Mystic Gohan finishes Buu without letting him pull any shenanigans. Universe is saved, Goku and Vegeta are dead still. Movie 12(Fusion Reborn) goes down. Black haired Gohan can one-shot Final Form Freeza.

[sintzu]

Movie 1 : Krillin wouldn't know who Gohan was throughout the entire movie.
Movies 2-5 : They'd take place after Goku's return form Namek during the 3 year wait for the androids, Vegeta would be training in space & Goku could use Ssj.
Movie 6 : Just remove the scene with Dende at the start. No one apart form Goku saw Vegeta go Ssj so it still fits with eveyrone being surprised when he used it against #19.
Movie 7 : It can take place after Goku wakes up and tell Vegeta about the time room but before they all go there.
Movie 8 : Takes place before the Cell games.
Movie 9 : After the Cell games.
Movie 10 : Before the 25th Tenkaichi and with Videl not seeing Gohan go Ssj it still fits with Buu's events.
Movie 11 : It doesn't get made.
Movie 12 : Before Goku goes to the Kais world he's told about a problem in otherworld where he meets Vegeta after getting his new body.
Movie 13 : After Buu.

You guys are missing the point of what AvatarReiko is asking... the question is, basically, "what would you change about the movies so that they could fit into the story of the main series?" It's an interesting question, and the opposite of the "what would happen differently in the series to let each movie happen" topic that pops up much more often.

They posted the same question over on Reddit's /r/DBZ community, so I already have a pretty in-depth series of answers ready to go. I'll just copy-paste it from here on out...

Spoiler:

• Movie 1: Not much needs changing here... you'd have to make it happen before Raditz's arrival, which means nobody at the Kame House reunion party can know Gohan exists yet. That mainly means you'd have to remove Kuririn from the battles at Garlic Jr's castle. Nobody should know about Gohan's rage boost either, but it's already easy to assume it went unnoticed during all the Dead Zone chaos.
• Movie 2: This would have to happen during the year of training for the Saiyans, so the main problem is Goku being dead. Since Goku knows he's not going to stay dead, you could have him elect to use his "free one day back on Earth" allowance to go save his friends and family from Dr. Uiro.
• Movie 3: This one is waaay out there... at this point in the series, most of the main cast of heroes were either dead from the Saiyan battle or already on Namek. You could have it happen after Goku recovered from fighting Vegeta but before he left for Namek himself. But unless you're going to cut out most of Tullece's crew, you'd be hard-pressed to have Goku fight them all alone with only, like, Muten Roshi and Yajirobe for backup. I suppose you could do the same thing as with Goku in the last movie, and have Piccolo, Tenshinhan, Yamcha, and Chaozu all return from the dead for the day. But if so...
• Movie 4: ...Then you'd be facing the same problem with THIS movie instead. Again, judging from the characters' strengths and such, this basically takes place mid-Namek. Maybe you could do a major rewrite by having it take place ON Namek instead, with Slug returning to exact revenge on his home planet for exiling him, but picking the worst time to do it. But then you'd run into the problem of what the heck to do with Freeza and however many of his own cronies he has left. This is a really tricky one, but if done right it could tie in quite well to Namek's history and Goku's emerging Super Saiyan power.
• Movie 5: Finally some easy ones again... This could take place after Future Trunks' first visit, sometime fairly early into the 3 years of training for the Androids. You'd just have to adjust Gohan's appearance to fit that time period, and alter things so that Goku can teleport and go Super Saiyan at will, like he should be able to. Maybe also address why Vegeta isn't around for some reason. Or heck, put him in the movie, and focus on his frustration at not being a Super Saiyan (yet).
• Movie 6: Kind of the same deal as 5, but a little trickier. It should take place sometime late in the 3 years of training, very soon before the Androids' appearance. It'd be easy to keep Vegeta being a Super Saiyan secret from everyone but Goku, and even easier to just... not have Dende be around as Earth's god yet. The main problem is that the cast shouldn't know where New Namek is yet, so... perhaps just have Coola come to Earth (again) instead, taking another shot at revenge on Goku. He could plop the Big Gete Star into one of Earth's oceans or something.
• Movie 7: Another tricky one. Maybe you could set this during the period of the Androids arc where Goku is asleep and recovering while everyone else is chasing Cell around. 13, 14, and 15 could either just be trying to find Goku like in the movie, or maybe you could change their mission to be some sort of anti-rebellion measures against 17 and 18 instead. Either way, the only major change is that for once, Goku won't get to save the day or fight at all, and so you'd have to figure out some new way to beat Super 13 instead of the Spirit Bomb. Maybe you could get Android 16 involved in a semi-heroic role, since he's supposed to be the strongest of all the Androids, even including Super 13...?
• Movie 8: Like with M7, this one could take place during a lull in the story where nothing else major happened, in this case the 10-day period before the Cell Games. The main thing you'd have to change is the state of Earth's population. In the series, basically all of civilization was shut down due to Cell's threat, so you'd have to make that the case in the movie too, instead of having people going to cherry blossom picnics and private school interviews in droves. Beyond that, it'd be pretty easy, especially since the bulk of it takes place away from Earth so you don't have to worry about Cell. For good measure, you should throw in some hint of Gohan being stronger than Goku, but without a full-blown revelation of it so it can still be a surprise at the Cell Games. Maybe just have him stay behind on Earth...?
• Movie 9: This one can already fit in the series! It's said to take place just a few months after the Cell Games, and the only minor inconsistency is Trunks having long hair again. Which can easily be explained by him having spent more time in the future than has passed in the... past. Outside of that, as far as I know everything else in the movie fits fine.
• Movie 10: The only major thing keeping this one from fitting in the series is that its predecessor Movie 8 couldn't have happened in the first place. With that "fixed," there's not much that needs changing. It can happen during the one month time-skip before the 25th World Tournament. If you went with the "Gohan stayed behind on Earth" idea for Movie 8, then maybe you could bring in Vegeta to help fight Broli for a personal touch and connection from before.
• Movie 11: I was going to suggest simply setting this one immediately after the Majin Boo arc, but unless you're willing to change the order of the movies, that would majorly interfere with Movie 12. So instead, maybe tie it into the Majin Boo ordeal somehow. Bio-Broli could be intended as a weapon against Majin Boo, and as such Mr. Satan is still dragged into this situation for some blackmail-related reason by Jaga and the con-man shaman, who both know he's a fraud. Eighteen gets involved to sort of protect Satan since he owes her money, and that in turn drags Kuririn, the boys, and probably Piccolo into it too. In the end, maybe you could have Goten and Trunks use Fusion and have SS Gotenks defeat Bio-Broli, as a way of testing his power before facing Majin Boo.
• Movie 12: You could do this one more or less the same way that the Buu's Fury game did, by placing it right in the middle of the Majin Boo arc while Goku and Vegeta are both still dead. The soul-cleansing tanks overloading could be a direct result of Majin Boo killing so many people on Earth. You'd have to forgo the tournament-based prologue and replace it with a pick-up from some part of the main story. Maybe do away with or at least minimize the whole "dead coming back to life" aspect of it, and keep this particular story limited solely to something Goku and Vegeta deal with in the afterlife while Majin Boo is still the main issue on Earth.
• Movie 13: This one is already pretty easy to fit, assuming it takes place sometime soon after the Majin Boo arc. It would have to be a year or so later at least, if the Dragon Balls are usable again after wishing for Earth's population to forget about Boo. Beyond that, the only real inconsistency is SS3 Goku being implied as stronger than SS3 Gotenks or Ultimate Gohan, per Toei's usual MO. That's not a problem in the Toei-Land version of the anime and its late-game retcon attempts during the Pure Boo battle, but the course of battle in this movie can be made to work with the original and consistent manga story too. All you have to do is confirm that Trunks cutting Hirudegarn's tail off weakened him (as some fan-theories already assume), allowing Goku to defend against him until he could land the Dragon Fist. Ta-da. On one last note, maybe include Mr. Boo or at least Piccolo in the movie, instead of upholding their bizarre absence.

[Grimlock]

In order for Movie 13 to fit in the mainstream continuity, Bulma would not learn about how to deal with a Time Machine in Dragon Ball Super. Or, I would place Movie 13 after the events of Future Trunks saga, thus not only that Time Machine that appeared in the movie would make sense and not being a huge plot hole, Majin Buu could appear, as it wouldn't take place during the six months after Majin Buu saga, where Majin Buu couldn't appear until Shenlong erases the memories of everyone about him.

You guys are missing the point of what AvatarReiko is asking... the question is, basically, "what would you change about the movies so that they could fit into the story of the main series?" It's an interesting question, and the opposite of the "what would happen differently in the series to let each movie happen" topic that pops up much more often.

Wow, not sure how I missed that distinction...that does make for a more interesting conversation. Let’s see...

Movie 1—Well, I see this one taking place before Goku introduces his kid to the others so really, you’d need to either reference them having already met him or you could throw in a little humor when Goku tells them why he needs the radar “Since when do you have a kid?! Don’t you tell us anything?!” You’d likely get a similar reaction from Krillin when he shows up to help Goku “Why didn’t you tell me you had a kid?!” The series would need to change when Goku shows up with Gohan as they would have already known about him but with the exception of Krillin, not met him. Might actually add some weight to why Gohan seems to bond the most with Krillin out of that group—Krillin was the one taking care of him while Goku was fighting.

Movie 2/3/4/5/6/7/8 The main issue with these seems to be that they seem to take place when Gohan is Namek age and before Goku can go Super Saiyan. Obviously they were a little busy on Namek so maybe age them up a bit and have these take place during the three years of training before the Androids? Maybe during the first year even? Gohan’s tail grows back after Goku returns from space. Goku when he meets Trunks cannot turn Super Saiyan at will. Maybe even swap the order around—Goku returns from space, Dr Wheelo is interested in him because of the stories of the “golden haired fighter” and takes Bulma and Roshi to force his hand and despite his best efforts, he can’t quite slip into Super Saiyan again, making him determined to train himself to achieve that form at will.

After the events of the movie, you now have Movie 5 where Goku does use Super Saiyan but reluctantly and with a great deal of effort.

Then you have Movie 4 with the main difference being Gohan still has his tail. Goku goes “False Super Saiyan” as he still has not completely mastered the transformation and by the end of the movie slips into full Super Saiyan, showing a gradual mastering of it.

Then you have Movie 3. After Goku cuts off Gohan’s tail he faces off against Turles as a Super Saiyan and it turns out the Fruit of the tree boosts his strength enough to go toe to toe with a Super Saiyan.

The second year of training for the Androids, you have movies 6 and 7. Have Movie 7 happen first when they get their first look at the kind of abilities the Androids have. Trunks arrives back in Time earlier than expected and instead of going back, opts to stay and help train instead. Vegeta makes his Super Saiyan debut here instead of later.

For Movie 6, swap out Kami for Dende as relaying the Namek call for help.

The third year of training before the Androids has Movie 8. The one major change is that Gohan can’t go Super Saiyan yet and is a little younger. Trunks is still around, waiting for the Androids to arrive. They all still fight against Broly with Piccolo using the fact that Gohan is continuing to fight despite not being able to go Super Saiyan as a major dig at Vegeta’s pride to get him moving.

The Androids arrive with a Trunks recognizing they’re different right away. The rest of the season, except for Vegeta having already mastered Super Saiyan and them having already met Baby Trunks goes as expected.

Year or two after the Cell Games, Movie 9 happens

Gohan starts school a year earlier, meeting Videl earlier. Their high school days lead to Gohan teaching her to fly and she figures out his strength on her own. Movie 10 happens.

The World Tournament happens without Goku’s involvement, leading to 18’s deal with Mr Satan. Movie 11 happens.

Babidi appears and tracks down energy for Majin Buu much more slowly. Goku uses his one day to come to Earth when he hears about Buu by meeting Supreme Kai. Babidi takes over Vegeta and he and Goku have their fight before Vegeta dies fighting Buu as Babidi dies. Goku and Piccolo teach the kids fusion while Supreme Kai And Gohan get in his training. Because of the battles with Broly and such, Gohan hasn’t had as much time to slack and draws and ends up breaking the Z sword much earlier, releasing Old Kai

Mr Satan meets and befriends Buu before he does nearly as much damage resulting in Buu going fairly dormant for a time and temporary peace resulting. Movie 12 happens.

Due to the chaos caused by Movie 12, the hunters emerge end up shooting Bee and injuring Satan. Evil Buu emerges and goes on his spree. Gohan revisits Supreme Kai after being thrashed soundly by Buu. Old Kai unleashes his dormant power. Saga continues as normal.

Following the events of Buu, Movie 13 happens.

I’m sure I got some details wrong but that’s the best I can come up with. It’s actually fun to imagine the series with these intertwined!
