This is a list of inconsistencies in the subject matter of the Dragon Ball manga, the anime series Dragon Ball, Dragon Ball Z, and Dragon Ball GT, and various video games within the Dragon Ball franchise.
- At the conclusion of the chapter "Carrot Top", Goku bounds Monster Carrot and his subordinates and carries them to the moon on his Power Pole. During Dragon Ball Z however, many characters assume that Goku cannot breathe in outer space such as Dr. Brief, who designs a state of the art spacecraft for Goku's travel to Planet Namek, equipped with an emergency space suit, and Frieza, who ruptured Namek with the conscience that even if Goku would survive the planet's destruction, he would die of asphyxiation in outer space. However, nobody has realized Monster Carrot and his men would have died too, not because the moon was destroyed, but because of asphyxiation. (This is probably more of a gag and is not supposed to be taken seriously, though.)
- In the chapter "The End of the Tale", Goku's size while transformed into a Great Ape is inconsistent between panels. At one point, he is seen bursting through the upper floors of Emperor Pilaf's castle, and has a size comparable to the whole structure itself. Later, the Great Ape is depicted as being roughly three times the height of Yamcha (as the two are illustrated together in one panel).
- When Goku starts his second quest to find the Dragon Balls (during the Red Ribbon Army Saga) only eight months have passed since the last time they were gathered, meaning that the Dragon Balls should not be able to be tracked yet.
- The color of Bulma's panties change three times during the General Blue Saga which took place all in one day giving her no chance to change her underwear let alone her clothes. Her underwear is plain white in the episode "Kame House: Found!". Her underwear is shown again inside the Pirate Cave in "The Trap is Sprung" where they are white but with strawberries on them and, the final time, in "The Pirate Treasure" when she strips down to them to swim where they are completely red.
- After defending himself from an oncoming Kamehameha, Mercenary Tao's clothes appear to have been rendered simple rags. However in the sequences that follow, Tao's pants appear completely untarnished.
- It is originally established with King Piccolo that a Namekian's blood is colored red. However, Drum is the first Namekian shown to bleed purple, as do all subsequent Namekians during Dragon Ball Z.
- In Dragon Ball Z, Kami claims he has no memory of being an alien, but earlier in Dragon Ball during the 23rd World Martial Arts Tournament while in Hero's body Kami tells Yamcha he is from another planet.
Dragon Ball Z
- In "The Arrival of Raditz", Raditz claims that Planet Vegeta was destroyed when a comet crashed into it three years prior. While the surviving Saiyans are under the impression that their home planet really was destroyed by a comet (except Vegeta, whose belief otherwise is shown in a flashback later in the series, although only in anime filler), it was later established that Planet Vegeta was actually destroyed 24 years prior to Raditz's arrival on Earth (the planet's destruction would soon be illustrated several times, and was often used to depict backstories for characters in Dragon Ball films), thus retconning the statement.
- While training in the Pendulum Room, Tien Shinhan, Yamcha, and Krillin are told that they had gone to the Planet Vegeta 100 years prior. This would be quite impossible, as the Saiyan-Tuffle war began only 40 years prior, and the planet would not have been called Vegeta yet, and the planet would not have been barren and without Tuffles.
- In the episode "Princess Snake", Goku has a nightmare where Nappa and Vegeta attack Chi-Chi and Gohan. However, at this point in the series, the only Saiyan he is familiar with besides himself is his brother, Raditz, and so he should not have any idea what Nappa and Vegeta look like.
- In "Reunions", it is revealed that Grandpa Gohan found Goku and his space pod somewhere in the woods (presumably somewhere within Mount Paozu). However, in "The End of Snake Way", Goku's space pod is mysteriously somewhere in the desert.
- When Goku uses the Kaio-ken in battle against Vegeta, the manga narration states that it doubles Goku's power. However, when Vegeta proves too strong, Goku uses a move he believes is more powerful, the Kaio-ken x2. According to the Daizenshuu, higher numbers multiply Goku's power by the number stated, meaning that Kaio-ken and Kaio-ken x2 should have the same result. The reason that Kaio-ken x2 was stronger is never resolved, and crates an inconsistency between the manga and the Daizenshuu.
- During the scene in the episode "The Ruthless Frieza" where the Capsule Corporation spaceship built for Goku by Dr. Brief takes liftoff, the Capsule Corporation logo on its outer surface reads "CPSULE CORP.", rather than "CAPSULE CORP.". Unlike some animation errors, this was not corrected in Dragon Ball Kai.
- While fighting, Recoome gets most of his teeth knocked out, but a few scenes later he has most of his teeth back.
- In a scene during his face off with Frieza, Vegeta is shown wearing his old armor which he wore at the beginning of the saga, despite the fact that he had switched to a new armor just before his face off with Frieza.
- The length of Frieza's tail after being partially severed by Krillin's Destructo Disk is never consistent. In select sequences that follow, Frieza's tail is sometimes shown completely intact.
- In the episode "The Ultimate Battle", there is an inconsistency between Krillin's uniform in two adjacent scenes. Krillin, who had been wearing a Battle Armor since the Frieza Saga began, is seen wearing his training gi briefly during a scene where he, Piccolo and Gohan flee the area to allow Goku to face Frieza. Making matters more curious, this sequence occurs in literally the following frames after Krillin is shown, wearing the battle fatigue. This was NOT corrected in Dragon Ball Kai, despite Kai correcting numerous larger animation errors.
- During the episode "Trump Card", the Ginyu Force, minus captain Ginyu, arrive on King Kai's planet where they are greeted outside of the kai's home by King Kai, Yamcha, Tien Shinhan and Chiaotzu. The Ginyu Force then proceed to test their special abilities in the planet's atmosphere by destroying King Kai's property. However, the early sequences of the following episode, "Keep the Chance Alive", seem to partially ignore this discovery, as while it seems to pick up where the destruction left off in the previous episode, King Kai is shown stepping outside of his home (which is where the Ginyu Force were initially discovered in "Trump Card", and which by the end of the episode had been partly caved in by a tree). King Kai is then shown to be surprised at the sight of the soldiers, despite being among his understudies when the Ginyu Force had first arrived in the previous episode.
- At the beginning of the episode "Power of the Spirit", Frieza remarks his astonishment that not all the Nameks have been killed, upon recovering from a counterattack by Piccolo. However, at this point, Frieza had been aware of Piccolo's presence for no less than ten episodes, as Piccolo was the first Z Fighter capable of showing Frieza any sort of challenge, while he was in his second transformation. In fact, the reason Frieza killed Dende was because he saw him heal Piccolo.
- In "Transformed at Last", during the aftermath of the Spirit Bomb, Krillin and Gohan fly over to Goku and Piccolo and land on a small island. In one screen, Krillin is shown missing the armor on his legs (that he's had since he received the armor from Vegeta) and in the next screen, they suddenly return.
- As established in "Goku's Unusual Journey", when it is requested that a character receive some treatment in the afterlife besides passing onto Heaven or Hell, that character's physical body vanishes, allowing them to retain it in the afterlife, rather than becoming a generic wisp. However, the members of the Ginyu Force who appeared on King Kai's planet were secretly invited there, and have retained their bodies and been crowned halos. This is not concise with the events of "Goku's Unusual Journey, however, as in that episode, where Goku's body vanishes from his final resting place, in "Namek's Destruction" Gohan flies by the corpses of the Ginyu Force members who were invited to King Kai's planet in the Other World.
- In the FUNimation dub of episode 85, "Gohan Returns", the dialogues of Gohan and Frieza, as well as the result of the fight directly prior, lead viewers to believe that Goku has been killed, and then revived by the Dragon Balls. In most other versions, including the original manga, Goku is merely knocked out for an extended time.
- There are several inconsistencies with landmarks on the surface of Namek during its destruction. For instance, the pillar where Guru's home is perched atop is demolished, causing the eldest Namek's home to plummet. However, when the Nameks are revived by a wish Mr. Popo makes to Shenron, the home is later shown resting on a plateau, with Guru's body still resting soundly upon his throne. Another inconsistency involves Goku's spaceship which Bulma, Gohan and Piccolo would be using to escape the collapsing Planet Namek. While a fault line forms underneath the spaceship causing it to sink into a resulting chasm, it is later shown spontaneously resting on solid ground in subsequent episodes.
- In the episode "Namek's Explosion... Goku's End?", after a conflict with Gohan, Vegeta takes flight and disappears in the distance. However, in the following episode, "Goku's Alive!!", Vegeta is again seen among the survivors of Planet Namek, despite leaving in the episode prior.
- In the episode "Goku's Alive!!", Moori is appointed by Guru as his "Eldest Namek" replacement. However, when Guru pronounces his name, he calls him 'Moly'. It was not until "Goku's Alive" that 'Moori' was established to be the Namek's concrete name.
- There are a number of inconsistencies with the area surrounding Goku's house. Early in Dragon Ball Z (as well as the first Z film, Dead Zone), Goku's house lies at the foot of a forest and at the base of a mountain. This is also the surrounding area as seen at the conclusion of the episode "Goku's Alive!!", where Piccolo is standing atop this mountain, looking down on the house. In other episodes, among them "Goku's Ordeal", the house is located on a grassy plateau, with the mountain and surrounding forest absent. "Goku's Assassin", as well as several episodes that follow, shows a surrounding terrain similar to the one seen in "Goku's Ordeal", but with the inclusion of a lone tree nearby, as well as a pond situated next to the house. "Closing In" shows a completely different terrain, when an aerial view of the surrounding land shows a river along the side of the property, along with what appears to be farming fields just beyond the house. In this view there also appears to be some minor modifications done to the shape of the structure as well.
- In "Z Warriors Prepare" while Goku, Gohan and Piccolo are training, Goku is shown wearing his blue undershirt. However in another frame where he exchanges blows with Piccolo, he is shown wearing his orange shirt.
- In episodes such as "Goku's Ordeal" and "A New Guardian", Chi-Chi laments over her inability to drive a vehicle. However, there are several sequences during the Saiyan and Garlic Jr. Sagas where Chi-Chi, accompanied by her father, is shown driving a hovercar and an aircraft, respectively. She also seen driving car after her wedding in a flashback in "The Newest Super Saiyan".
- During the Namek Saga, it was established that Nameks only need water to sustain themselves, which is further demonstrated by Piccolo during his stay with King Kai. This diet's roots can be traced back to Dragon Ball, when King Piccolo's attempt to order food in East City is rejected by Piano, who rebuts that King Piccolo is not capable of consuming food. However, in the Piccolo Jr. Saga, Piccolo is shown eating fish. Later in Dragon Ball Z, when Chi-Chi declares in "Goku's Ordeal" that she will no longer be cooking meals for the family until Goku and Piccolo obtain a driver's license, Piccolo (who is a guest at their residence during the three-year preparation for the androids) appears to be just as distraught as Goku, which should not be the case as his meals consist simply of water. Even more so, there is little reason why he actually goes through with driving lessons while continually ridiculing them, when Chi-Chi not cooking for the family would have absolutely no effect on his diet. This inconsistency is more than likely for comedic value, but it does present a plot hole, nonetheless.
- When Android 18 stole her cowgirl looking uniform from a clothing store, it showed the license plate on the Androids pink van that they stole. It said 69-69. However, later on when they were being chased by the Toad Warrior bike gang, it showed their license plate again, but this time, it said BB 1223.
- In the episode "Bow to the Prince", while Goku and Gohan are training in the Hyperbolic Time Chamber, Goku instructs Gohan to imagine that Cell is destroying everyone close to him, in an effort to trigger the Super Saiyan transformation inside him. Gohan dispels this method, confessing that he has never seen Cell. However, later during their stay in the Hyperbolic Time Chamber, Gohan has a nightmare where Perfect Cell kills Chi-Chi and Piccolo. Apart from the fact that Gohan has never seen Cell at this point in the series, this is even more unfounded because Cell did not achieve his perfect form until after the pair entered the Hyperbolic Time Chamber.
- In "Awakening", Gohan kills eight Cell Jr., even though Cell only created seven of them.
- While attacking Cell during his Beam Struggle with Gohan, Tien Shinhan states to himself that surpassing Goku had been his goal ever since becoming a martial artist, and that if it were not for Goku he would not be as strong as he was. However, it is known that he was a martial artist under the Crane Hermit long before he met Goku.
Majin Buu Sagas
- When Goten and Trunks' Mighty Mask disguise is cut in half by Android 18 at the World Tournament, they immediately take off the ripped clothes and throw them away. The kids are then disqualified and fly away. Later on they are shown taking off the ripped clothes again right before meeting Videl when she is flying.
- In a scene during the face off between Majin Vegeta and Goku, Goku is seen without his halo, despite the fact that he was dead at the time.
- In the episode "The Warrior's Decision", right before Vegeta uses the Final Explosion in an attempt to destroy Majin Buu, Piccolo tells him that he will not be able to keep his body in the after-life as Goku did since keeping your body is a reward given to those who selflessly dedicate their lives to doing good and helping others. Yet in filler episodes, villains such as the Ginyu force (minus captain Ginyu), Frieza, and Cell are shown in Hell with their body.
- Early in the series, it is stated by King Kai that once you are dead you can not die again. This is also stated by Dende, the Alien Announcer, and a few others throughout the series. However, it is stated by Goku during the Buu Saga, that if someone dies while dead, they cease to exist.
Dragon Ball GT
- Only in the FUNimation Dub of "A Devastating Wish", when Goku and Uub emerge from their sparring session and collapse, Dende asks Mr. Popo to retrieve a first aid kit. This should not be necessary, as Dende has healing abilities at his disposal.
- During the Super 17 Saga, deceased villains in Hell and on Earth are shown without halos, despite being crowned with them in filler episodes of Dragon Ball Z, but they have ones while waiting in front of the Check-In Station.
- In the FUNimation Dub of "Until We Meet Again", Krillin claims that Turtle is nowhere near 1000 years old, however Turtle celebrated his 1000th birthday in the filler episode "Krillin's Proposal".
