History Fanon / DragonBall

** Speaking of Freeza, given how murky or nonexistent his backstory is, fanon has inevitably attempted to fill in the gaps, regarding everything from the name of his [[NoNameGiven race/species]], to his [[ReallySevenHundredYearsOld actual age]], to [[DarkAndTroubledPast why]] he is [[AlternativeCharacterInterpretation apparently]] the only villain in ''Dragon Ball Z'' who is [[LawfulEvil evil of his own free will]].

* Because [[NoodleIncident it's never revealed]] how Bulma and Yamcha's relationship ended, it's common for fans to assume that she dumped him after he cheated on her. This theory is popular even though Bulma shows no signs of resentment towards Yamcha after breaking up with him.

* The most commonly accepted explanation for the heart disease that took Goku out of action in the Android saga and killed him in Future Trunk's timeline is that he contracted it on Yardrat and brought it to Earth. Despite showing symptoms a year later in Trunks' timeline and three years later in the regular timeline, diseases lying dormant in a body for years is not unheard of, it's actually a TruthInTelevision. We're not given enough information on his heart disease to understand what it fully is but many fans assume it to be a virus of some sort because it fits the characteristics of [[https://en.wikipedia.org/wiki/Virus_latency virus latency.]] Also, if not a virus, there is the possibility of [[https://en.wikipedia.org/wiki/Incubation_period incubation period]] which is the period between infection and clinical onset of the disease. It's possible that training for the Androids gave Goku a healthier body which allowed his immune system to fight off the disease for a longer period of time but on the day of the Android attack fighting them overexerted his body and the pathogen struck. Which could be related to the French dub saying he got it on Namek (and yes, why then Vegeta, Krillin and co. didn't is anyone's guess).

* Apparently, in certain parts of the fandom, Goku is a horrible father who never took the time to raise his kids, whereas Piccolo was the "true father" who raised Gohan instead. This ignores the fact that Goku was perfectly fine helping Chi-Chi raise Gohan for four years (and would've continued if Raditz didn't kill him), raised Gohan for three more years afterwards, and spent yet another year in the Hyperbolic Time Chamber with Gohan before dying again. This, compared to Piccolo "raising" (after literal kidnapping) Gohan for only six months/one year. The numbers don't really add up.

* In the 2014 full color re-release of the manga, Creator/AkiraToriyama revealed that Android 16 was modeled off of Dr. Gero/Android 20's son, a Red Ribbon Army soldier who was killed by enemy gunfire. However, plenty of fans don't know or recognize that last fact and instead believe that Gero's son was killed by Goku during the events of the original series, which is why Dr. Gero wanted revenge against him. This mistaken impression is probably aided by the fact that in ''WebVideo/DragonBallZAbridged'', Goku ''did'' kill the younger Gero (as seen in a rather well-made original animation in Episode 56).

* Another less disturbing bit of fanon is the general acceptance that the heart disease that took Goku out of action in the Android saga, leading to the havoc on the world in the alternate timeline was caught by Goku on Yardrat and brought to Earth. Despite contracting it a year later in Trunks' timeline and three years later in the regular timeline, diseases lying dormant in a body for years is not unheard of, it's actually a TruthInTelevision.

** Saiyans mate for life and their tails or tail spots are an erotic area.

*** It's canon, at least for Goku; him reading Krillin's mind on Namek is in the manga. Goku can read minds (jury's out on the rest of the Saiyans), he just never remembers that. Yep, useless-ass psychic powers.
** A small section of the fandom believes that male Saiyans are capable of [[MisterSeahorse getting pregnant and bearing children]], due to the fact that nearly all of the Saiyan characters that have shown up in the series are male. [[{{Jossed}} Largely disproven by now.]]
** A different portion took the same evidence and came to the conclusion that Saiyans have a higher sex ratio than humans, such that male births are more common than female births.
* Yamcha was fired from his baseball career for being in a fight. Not only is this never mentioned and was Yamcha explicitly holding back, but the characters indicate that fights breaking out were a common occurrence in the stadium (likely a reference to hockey riots). Yamcha is also seen playing after the Saiyan Saga and all the way into ''Super'', disproving this. This one was seemingly motivated by RonTheDeathEater.

* There seems to be a consensus among fans Chi-Chi is the reason Gohan stopped training in the 7 years between Cell and Majin Buu Sagas. Gohan is the reason Gohan stopped training. He doesn't like fighting, period.

* A widely accepted fanfiction idea is Vegeta was raped/abused by Freeza at some point during his time working with him, and the abuse/rapes were what fueled his treachery.

* Capsule Corp is usually portrayed in fanfiction as an economic giant with resources to rival a small country. While [[Fiction500 not inaccurate]], this often carries the side effect of Bulma having fame to match post-Cell Games Mr. Satan. The closest the actual series gets to this is when the people of West City shrug off Porunga's summoning as another one of Capsule Corp's crazy experiments.

*** He was called "Mr. Savage" on some of the earlier ''DBZ'' products before the Cell Saga premiered in the U.S. Savage (an actual surname in real-life) could be his real last name (i.e. Mark Savage).

* In the manga, it is stated that the Saiyans from Universe 6 evolved in a different way from their counterparts, losing their tails in the process. Some fans like to theorize the Universe 6 Saiyans come from a long line of mixed relationships, very similar to how Goten and Trunks are half-human, half-Saiyan breeds, and this explains why they are so powerful, something that isn't exactly stated.

* The Super Saiyan 4 form name, for the fans who saw Broly's legendary transformation being adapted and being named "Berserker Super Saiyan", has earned the FanNickname of "Super Saiyan Feral", among others. It helps the form is not really an evolution of Super Saiyan 3 and does not resemble the previous Super Saiyan transformations at all.

** Along with this, for fans who didn't believe in the legend to begin with (since regular Super Saiyan is supposed to be already what the legend is like), a popular theory was that Kale and Broly were {{mutant}}s to the Saiyan race like Freeza and his father were to theirs. Became AscendedFanon in ''Anime/DragonBallSuperBroly'', with King Vegeta calling Broly a sort of mutant, though it's still never being explicitly said if the same applies for Kale.

** The idea that Freeza's entire race is as naturally powerful as himself. While King Cold, Cooler, [[Anime/DragonBallEpisodeOfBardock Chilled]] and [[Anime/DragonBallSuper Frost]] do have comparable power, WordOfGod says that Freeza is a {{mutant}} member of his race that, like his father, was born with abnormally huge power. There's also the idea that Frieza's entire line undergoes the same transformations, where only Freeza and Frost had forms highlighting their Bio-Armor, and Cooler alone has a fourth transformation. In particular, there's a recurring idea among some circles that King Cold can transform, though there is absolutely no evidence for this in any official material (not even WhatIf-obsessed media like ''[[Anime/SuperDragonBallHeroes Heroes]]'').

*** It's canon. Goku reading Krillin's mind on Namek is in the manga. Saiyans can read minds, they just never remember that. Yep, useless-ass psychic powers.

* Broly. Due to a liberal translation in the [=FUNi=] dub of the movie, he is almost universally thought to be increasing his power level at a constant rate, indefinitely, while in his Legendary Super Saiyan form. (The ''Webcomic/DragonBallMultiverse'' fan manga has actually made it a plot point.) That Broly replenishes his Ki and stamina and keeps them at the top no matter how long he fights is closer to the truth. [[RightForTheWrongReasons Which, given the Saiyan ability to grow stronger every time they fight really could lead to power increases]]; not endlessly getting stronger, but close enough that no one can tell the difference.

*** He was called "Mr. Savage" on some of the earlier DBZ products before the Cell Saga premiered in the US. Savage (an actual surname in real-life) could be his real last name (i.e. Mark Savage).
** In fact, canonically the only characters in the show who do have last names are the '''Son''' family, our main characters Son Goku, Son Gohan and Son Goten. When Gohan went to high school, other students even pointed out how unusual it was that he had a last name. Also, of course, Son Gohan Sr. Contrary to popular belief, though, not Chi-Chi. She is never called that way in the series, and Chinese women do not change their last name in marriage.

* Fans like to speculate that Android 17's wife is L(a)unch, a character infamous for undergoing ChuckCunninghamSyndrome in between the original ''Manga/DragonBall'' and ''Z''.

** The idea that Freeza's entire race is as naturally powerful as himself.

*** Likewise in Super, there's an episode where future!Mai seems to communicate with Future Trunks telepathically (he hears her voice despite her lips clearly not moving).
*** It's especially bizarre since we see in Dragon Ball that Master Roshi can read minds if he focuses. Saiyans, meanwhile, didn't even know ki sensing was possible so it doesn't seem likely they'd have been able to use telepathy all this time.
*** It’s canon. Goku reading Krillin’s mind on Namek is in the manga. Saiyans can read minds, they just never remember that. Yep, useless-ass psychic powers.

Yamcha is also seen playing after the Saiyan saga, disproving this. This one was seemingly motivated by RonTheDeathEater.
* Another example is that Yamcha was terrified of the Saibaman and only decided to face them after Tenshinhan because of a desire for glory. Not only does Yamcha never display any fear of the Saibaman, but he explicitly volunteers in place of Krillin because the latter had already died in the King Piccolo arc and thus couldn't be revived by Earth's Dragon Balls.
* There seems to be a consensus among fans Chi-Chi is the reason Gohan stopped training in the 7 years between Cell and Majin Buu Sagas. Gohan is the reason Gohan stopped training. He doesn't like fighting, period. Extending to that Chi-Chi physically abusing Gohan with a frying pan when he didn't do what she wanted. She was strict with him, but never abusive.
* Apparently, in certain parts of the fandom, Goku is a horrible father who never took the time to raise his kids, whereas Piccolo was the "true father" who raised Gohan instead. This ignores the fact that Goku was perfectly fine helping Chi-Chi raise Gohan for four years (and would've continued if Raditz didn't kill him), raised Gohan for three more years afterwards, and spent yet another year in the HTC with Gohan before dying again.

%%* Videl states that surnames have fallen out of fashion in the world where ''Dragon Ball'' takes place, to the point where she guesses that Son Gohan is the son of Son Goku because very few families still use surnames. Nonetheless, it's common for fans to give characters surnames, for example, Bulma Briefs and Videl Satan, despite those being Bulma's father's given name, and Videl's father's stage name, respectively.

* A lot of fans [[FanonDiscontinuity who refused to acknowledge the existence]] of ''Episode of Bardock'', the sequel of ''Father of Goku'' where Bardock turns into a Super Saiyan, with the belief that story is just a prequel to the events of ''Videogame/DragonBallHeroes'' or ''Videogame/DragonBallXenoverse'' and that Bardock was sent to the past by BigBad Towa. Keep in mind the author of said story just stated is a WhatIf Story.

* In the 2014 full color re-release of the manga, Creator/AkiraToriyama revealed that Android 16 was modeled off of Dr. Gero[=/=]Android 20's son, a Red Ribbon Army soldier who was killed by enemy gunfire.

** Bulma '''Briefs''', though this misconception is caused by the dub. Bulma’s father is called Dr. Brief and the dub assumed that was his last name because that’s how it’s usually done in real life. However, in the Dragon Ball universe, that’s just his title followed by first name. The dub also called Bulma’s mom “Mrs. Briefs, which cemented Brief as a last name. She was just called “Bulma’s Mom” in the manga and anime, though Toriyama said that if he'd given her a name it would have been “Panchy”.
** Videl '''Satan''', another misconception also caused by the dub when Mr. Satan’s name was censored as “Hercule”. Thus, fans assumed his name is “Hercule Satan”, when in reality, Hercule is a dub-only name, Mr. Satan is his ring name, and his actual name is revealed only in supplemental as Mark (an anagram of ‘Akuuma’ in Japanese, meaning ‘devil’ keeping the theme name with his daughter).

** In fact, canonically the only characters in the show who do have last names are the '''Son''' family, our main characters Son Goku, Son Gohan and Son Goten. When Gohan went to high school, other students even pointed out how unusual it was that he had a last name. Also, of course, Son Gohan Sr. Contrary to popular belief though, not Chi-Chi. She is never called that way in the series, and Chinese women do not change their last name in marriage.

* Before [[Anime/DragonBallSuperBroly Broly]] [[CanonImmigrant was integrated into the canon of the series]], many fans believe Kale is his AlternateSelf just like how Frost is one to Freeza, and she is the Legendary Super Saiyan. At least in the manga, she is considered the ''Legendary Saiyan'' or a "Demon Saiyan".
** Along with this, for fans who didn't believe in the legend to begin with (since regular Super Saiyan is supposed to be already what the legend is like), a popular theory was that Kale and Broly were {{mutant}}s to the Saiyan race like Freeza and his father were to theirs. Became AscendedFanon in ''Anime/DragonBallSuperBroly'', with King Vegeta calling Broly a sort of mutant.

* A lot of fans believe that thanks to having the DNA of Freeza and the Saiyans, Cell could actually obtain his own version of the Golden Frieza transformation from ''Anime/DragonBallZResurrectionF'', along with Godly ki, with only a few months of training. Cue to FanficFuel about ''Resurrection 'C'''.

* It's popular in the fanbase to pair up Hit with the Universe 6 Saiyans, with him as a sort of [[TheObiWan mentor]] to them, in some cases similar to what Piccolo is to Gohan. While in episode 111 of ''Dragon Ball Super'', Hit does encourages them to keep with their work to fight and win in the tournament, and they appear together in the [[NonSerialMovie out-of-continuity]] ''Anime/SuperDragonBallHeroes'', their relationship seems to be strictly professional; Cabba respects him and Caulifla ([[FusionDance as Kefla]]) wants to fight him in the videogames, but that's the extent of their relationship.

* Fans believed as a whole that ''Dragon Ball GT'' was an AlternateTimeline before ''Videogame/DragonBallXenoverse'' made this AscendedFanon.
* The Super Saiyan 4 form name, for the fans who saw Broly's legendary transformation being adapted and being named ''Berserker Super Saiyan'', has earned the FanNickname of ''Super Saiyan Feral'', among others. It helps the form is not really an evolution of Super Saiyan 3 and does not resemble the previous Super Saiyan transformations at all.

* A lot of fanfictions tend to have Vegeta [[HeyYou never calling someone by their name]] aside from Goku and Trunks, like "Earth Woman" for Bulma, "Kakarot's" son for Gohan, or "The Bald One" for Krillin despite the fact that Vegeta regularly call them by their name, particularly after his CharacterDevelopment.

* Another misconception is the idea that movie villain Bojack was [[SealedEvilInACak sealed inside King Kai's planet]] and released when it was destroyed by Cell's attempt at TakingYouWithMe. This resulted from the original English dub making things up; the original Japanese version simply said that he'd been sealed away by the Kais, and King Kai getting killed by Cell released the seal. This is another one ''Abridged'' has contributed to, which has Bojack literally being trapped inside the planet and occasionally conversing with its inhabitants (to King Kai's annoyance) as a RunningGag.

* In the manga, is stated the Saiyans from Universe 6 evolved in a different way from their counterparts, losing their tails in the process. Some fans like to theorize the Universe 6 Saiyans come from a long line of mixed relationships, very similar to how Goten and Trunks are half-human, half-Saiyan breeds, and this explains why they are so powerful, something that isn't exactly stated.

* Recurring fan theories involving Frieza:
** The idea that Frieza's entire race is as naturally powerful as himself. While King Cold, Cooler, [[Anime/DragonBallEpisodeOfBardock Chilled]] and [[Anime/DragonBallSuper Frost]] do have comparable power, WordOfGod says that Frieza is a {{mutant}} member of his race that, like his father, was born with abnormally huge power.

** ''Dragon Ball'' fanfiction is almost universally permeated with the notion that Saiyans undergo some sort of physiological/psychic connection when they fall in love, that Saiyans mate for life, refer to their love interests specifically as mates, and that the connection is formed in a process called "bonding" which involves one or both partners biting the other on the neck vampire-style. People may have originally gotten the idea for the psychic connection thing from a scene in the anime where Bulma gets a horrible feeling as Vegeta dies against Majin Buu. However, this is the only scene even close to suggesting this, appearing to show that numerous writers have blown it out of proportion.

Not only is this never mentioned and was Yamcha explicitly holding back, but the characters indicate that fights breaking out were a common occurrence in the stadium (likely a reference to hockey riots).
