From Dragon Ball Encyclopedia, the ''Dragon Ball'' wiki
Gogeta (ゴジータ, Gojiita; FUNimation "Gogeta") is the resulting Fusion of two highly powerful Saiyans, Son Goku and Vegeta, when they perform the Fusion Dance properly. His voice is a dual voice that contains both Goku's and Vegeta's voices. Gogeta's Super Saiyan 4 transformation is famous for his amazing power and speed, and is often regarded as one of the series' most powerful characters. His Potara Earrings Fusion counterpart is Vegetto. Gogeta is a filler character, meaning he has never appeared in the manga.
Gogeta wears the same clothes that all creations of the Fusion Dance wear. However, Gogeta's vest has a different color scheme than Gotenks'. The padding around the neck and shoulders of the vest is reddish orange rather than yellow, and the vest is either a very dark blue or a dark gray, rather than the lighter blue vest that Gotenks wears. The hair is very similar to Vegito's, with the only differences being that Gogeta only has one free hanging lock of hair instead of two and Gogeta having Vegeta's widow's peak.
Although they are made in the very same way, Gogeta has personality traits that are different from Gotenks, though it is impossible to tell which counterparts' personality is the dominant one. And since his appearances have been limited and short, it is difficult to tell if his personality is a separate one, or a composite of both Goku and Vegeta, although at Super Saiyan 4 it seems that his personality is like that of Vegito (which leans more towards Goku). Gogeta possesses Goku's body structure, he is tall and slender, but he seems to mostly possesses Vegeta's facial features. Super Saiyan 4 Gogeta can be equally serious as his Super Saiyan form or more if he needs to.
Gogeta was formed by the merging of two mighty Saiyans, Goku and Vegeta, via the Fusion Dance. He was the second Fusion performed through the Fusion Dance in the Dragon Ball Z series. He, like his Fusion son Gotenks, was a desperate Fusion done to defeat a powerful enemy; Gogeta's enemy was Janemba in Dragon Ball Z: Fusion Reborn and Omega Shenron in Dragon Ball GT.
 Dragon Ball Z: Fusion Reborn
In Fusion Reborn, Gogeta made an appearance during the end of the movie. After Janemba transformed into his Super Form and became too powerful for Goku and Vegeta to handle, Goku quickly taught the Fusion Dance to Vegeta. The Fusion Dance must be performed correctly to create a very powerful warrior, so when Vegeta failed to extend his index finger in the final step of the dance, this resulted in a much weaker fusion warrior named Veku. Veku was no match for Janemba, and for thirty minutes he frantically evaded the demon's attacks in comical fashion, clumsily stumbling and passing gas as part of his defense. The second time around and with the assistance of Goku's ally Pikkon, the Fusion Dance was performed correctly, and Gogeta was born. After an amazing display of speed and power, Gogeta finished off Janemba with the Stardust Breaker. With the elimination of the Negative Energy that had created Janemba, the creature reverted back into the young ogre, Saike Demon, who ran off in fear when he made eye contact with Gogeta.
 Dragon Ball GT
 Shadow Dragon Saga
This marks the last time the Fusion Dance was used between Goku and Vegeta in the series.
During Dragon Ball GT, Goku and Vegeta fused into Gogeta at Super Saiyan 4 to combat Omega Shen Long. Having achieved his ultimate potential, Gogeta easily overpowered Omega Shenron and even used his supreme power to gloat and toy with the Shadow Dragon. However, Gogeta spent too much time toying around with Omega Shenron and the fusion did not last as long as expected because of the tremendous power he possessed, thus he was unable to finish him off.
 Video games
Gogeta appears in various Dragon Ball video games. In games such as Dragon Ball Z: Budokai 3 and Dragon Ball Z: Buu's Fury, he appears as a Fusion. His fat version also appears in Budokai 3. In the Budokai Tenkaichi video game series and other fighting games, he is revealed as an actual character. The game Dragon Ball Z: Ultimate Battle 22 mistakenly refers to Gogeta as Vegetto, and implies that a Potara Earrings Fusion results in Gogeta when the actual case is that only the Fusion Dance can form Gogeta. Interestingly enough, the game also incorrectly gives Gogeta the Final Kamehameha, which is widely recognized as Vegetto's signature attack whereas Gogeta's signature attack is the Big Bang Kamehameha. Gogeta also appeared in Dragon Ball: Raging Blast in his Super Saiyan form, but not as a Super Saiyan 4 due to the game's omission of the Dragon Ball GT storyline.
In Budokai 3, after the defeat of Kid Boo and Broly, Goku and Vegeta fused and became Gogeta to fight Gotenks at the Tenkaichi Tournament. He easily beats them and complains their attitude is becoming similar to that of Hercule. In the same game, when Gogeta fights Omega in his Super Saiyan 4 form, he does not waste any time and defeats the Evil Dragon. In Raging Blast, Gogeta is able to fight and defeat his Potara Earrings Fusion counterpart, Vegito in the first half of the what if fight. In the second half of the What If, however, Vegetto manages to defeat him, but Gogeta asks how he would explain the permanent Fusion to Son Chichi and Bulma Brief, Goku and Vegeta's wives respectively, much to Vegetto's worry.
 Forms and transformations
Main article: Failed fusions
Veku was the fat version of Gogeta who occurred when Goku and Vegeta attempted to fuse for the first time. He was one of several failed fusions present in the series. Vegeta failed to extend his index finger, resulting in an embarrassingly weak Fusion, and they formed a fat, incredibly weak fighter who was called Veku by South Kaio. In this form, speed was decreased and ki was extremely limited. Veku, because of his state, was unable to perform any ki attacks due to the large drop in power. Also, because of his fat body, he could not retaliate by punching and kicking. Instead, all he could do was pass gas, which he used against Janemba to try and escape him. Just like a regular Fusion, the time duration was 30 minutes before the two fighters defused. This type of failed Fusion was also seen during the Majin Buu Saga by in Goten and Trunks when they formed Fat Gotenks after attempting to fuse for the first time. According to the Daizenshū, Veku has a battle power of 704.
 Super Saiyan (base)
Main article: Super Saiyan
This form is seen during Dragon Ball Z: Fusion Reborn. Immediately after the successful Fusion of Goku and Vegeta, Gogeta is at Super Saiyan as both halves (Goku and Vegeta) had previously mastered the transformation. Even though Janemba easily took care of Goku at Super Saiyan 3 and Vegeta at Super Saiyan 2, he was unable to even hurt Gogeta at all (a full force punch from Janemba to Gogeta's face didn't do anything). In a matter of seconds, Gogeta was able to destroy Janemba without any problem whatsoever. Even while at this lowest-level stage, he is still many times stronger than Goku at Super Saiyan 3, and Vegeta at Super Saiyan 2.
 Super Saiyan 3
Gogeta has the ability to go Super Saiyan 3 in Dragon Ball Heroes.
 Super Saiyan 4
Main article: Super Saiyan 4
This stage is seen in Dragon Ball GT where Goku and Vegeta both faced off against Omega Shen Long. With the Fusion Dance, they successfully created the powerful Super Saiyan 4 Gogeta. Unlike Vegeta and Son Goku's Super Saiyan 4 forms, Super Saiyan 4 Gogeta has brown fur and fiery crimson hair, instead of the opposite, and he is the only Super Saiyan that features blue eyes (without a strong green hint) as well. He is also the only character in the series with glitter in his energy aura. Compared to his more serious form, Super Saiyan 4 Gogeta is somewhat more playful and cocky (almost akin to Vegito's attitude), toying with the evil Omega Shen Long instead of easily defeating him, possibly because the power was going to his head, though Vegeta states that Goku was in fact responsible for this behavior (however, it could be possible that Vegeta was merely shifting the blame onto Goku). It could be implied that Gogeta's personality may be based on a combination of Goku's youthfulness and Vegeta's arrogance, though this is only speculation. It is also implied he was only doing this so Omega Shenron would use his Minus Energy Power Ball attack, which Gogeta could use to fully cure the planet of Omega Shenron's evil energy. This is likely, as Gogeta immediately tries to destroy Omega Shenron afterward. His speed in this form is the greatest seen in the series, being so swift, not even the viewer is able to see his movements. As an example, he was able to knock Omega Shenron away with what appeared to be a single, unseeable blow, but was later revealed to be three, almost simultaneous strikes. When Gogeta said he would slow down in his attacks, those same strikes appear as simple twitches, if anything. Along with his unbelievable speed, Gogeta also harbors an extraordinary amount of power and energy. As a Super Saiyan 4, Gogeta is seemingly invincible due to the massive power level gap between him and all other warriors in the series. His only weakness is his inability to stay fused for longer than 10 minutes due to the abnormally huge amount of power he possesses, which ultimately led to him de-fusing before he could deliver the final strike to Omega Shenron. This is similar to the way Gotenks defuses back into Son Goten and Trunks or falls out of his Super Saiyan 3 form before he can finish his foes off. At this point, considering the feats he has done, it is likely that he is nigh omnipotent and nigh omniscient, as he knew how to reverse Omega Shen Long's Negative Karma Ball, which stated by Elder Kai, could destroy the entire universe because of it's tainted power; though Gogeta stopped this from happening, and turn it into positive energy.
Main article: List of techniques used by Gogeta
 Stardust Breaker
Main article: Stardust Breaker
Otherwise known as the Rainbow Sparkling Blast or the Soul Punisher, Gogeta uses this technique against Super Janemba after Goku and Vegeta's successful fusion. First, he attacks his opponent with a flurry of punches and kicks. After smashing his opponent against the ground, Gogeta attacks his opponent with a tiny, rainbow-colored sphere (hence the nickname "Rainbow Sparkling Blast") which attacks him/her from the inside, reducing them to glittery gold dust.
 Big Bang Kamehameha
Main article: Big Bang Kamehameha
Gogeta first uses this technique in his Super Saiyan 4 form against Omega Shenron during the Shadow Dragon Saga, right after he had deflected Omega's Minus Energy Power Ball. The attack is a hybrid of Goku's Super Kamehameha and Vegeta's Big Bang Attack, with the former appearing to be more dominant in the beam's appearance. First, Gogeta gathers the energy of the Super Kamehameha and Big Bang Attack in both his hands. Then, he forms this energy into a whitish-blue energy ball, about the size of Gogeta himself. Finally, he fires the sphere off in a Kamehameha-esque beam, which can deal an extremely large amount of damage. Vegito's ultimate technique, the Final Kamehameha, is performed in a similar manner, though he fires the ball off in its original state rather than changing it into a beam.

- Gogeta is one of only three characters (Cooler and Cold being the other two) in all of Dragon Ball Z to never be shown in their base form.
- In Fusion Reborn, Gogeta is not seen as cocky whatsoever when compared to his Super Saiyan 4 form, and he eliminates his enemy quickly. As a Super Saiyan 4, however, he acts somewhat similarly to his Potara Fusion counterpart, Vegetto, as they both toy around with their respective opponent in order to achieve their true goal.
- A union of Goku and Vegeta via the Fusion Dance is mentioned in the manga/anime when Goku and Vegeta are trapped inside Boo's body. Goku suggests performing the Fusion Dance in order to defeat Super Boo, but Vegeta declines, already knowing what the Fusion Dance is and refusing to merge again.
- Super Saiyan Gogeta's hairstyle is more inclined to that of Super Saiyan Vegeta. Super Saiyan 4 Gogeta's hairstyle is more inclined towards that of Super Saiyan 4 Goku.
- Super Saiyan 4 Gogeta is the strongest character in both Dragon Ball Z: Budokai 3 and Dragon Ball Z: Infinite World with a total of 180% attack.
- Super Gogeta only has two lines in Fusion Reborn: "I am not Goku or Vegeta. I am Gogeta, it's over Janemba and I have come for you!" and "Every force you create has an echo. Your own bad energy will be your undoing!" Also, he laughs after Saike (who became Janemba) runs away after.
- Gogeta is the only Fused character that was formed by the Fusion Dance technique to have a halo, as both Goku and Vegeta were dead at the time.
- He is also the only fusion to be dead, as both Goku and Vegeta were deceased when they fused and fought Janemba.
- Strangely, after you unlock Gogeta in Dragon Ball Z: Buu's Fury, he still has a halo even though both Goku and Vegeta are alive. This was explained by the developers to be "because he's a secret character."
- In addition to this, Gogeta's Big Bang Kamehameha appeared in this game as one of his attacks, despite that this move first debuted in Dragon Ball GT. He also uses the technique Dragon Fist in Buu's Fury even though Gogeta never used the technique.
- Gogeta is the only fused Saiyan character (Potara Fusion or Fusion Dance) to successfully defeat a villain without the fusion wearing off (he defeats Janemba without even coming close to running out of time).
- In some video games, namely Budokai 3 and Budokai Tenkaichi 3, Super Saiyan Gogeta has been shown fighting Legendary Super Saiyan Broly in the introductory sequences.
- Even though Janemba is not in Raging Blast, Gogeta is playable. He is seen in a What If Saga and, surprisingly, his opponent is his Potara Fusion counterpart, Vegetto. He also appears in Budokai 3 without Janemba but fights his son, Gotenks in a what if scenario.
- Interestingly enough, in Raging Blast Gogeta has lightning surrounding his aura, which is typical of the Super Saiyan 2 and Super Saiyan 3 transformations. However, this might be in order to show Gogeta's power, and should not be confused as a Super Saiyan 2 Gogeta. When Gogeta's aura charges in the game, it does not have the same sound effects as it would have a Super Saiyan 2 or Super Saiyan 3.
- Gogeta is the only Saiyan, fused or otherwise, not shown with a base form. When he dies in Dragon Ball Z: Buu's Fury, however, his hair turns black like any Super Saiyan who dies and he also appears there as Veku and a unique skinny Gogeta, both black-haired.
- In Dragon Ball: Raging Blast's what if fight involving Gogeta and Vegetto, the English dub voice (FUNimation) of Gogeta has Goku's voice more pronounced than Vegeta's voice whereas Vegetto's voice had Vegeta's voice being more pronounced than Goku's voice.
- Gogeta is the only pure-blooded Saiyan Fusion using the Fusion Dance. Gotenks is half-Human.
- In every video game where Super Saiyan 4 Gogeta is playable, his alternate costume is similar to the Super Saiyan 5 Goku April Fools joke with his hair and fur being of the same color as in that infamous picture.
