Vegetto
Vegetto is the immensely powerful result of Goku and Vegeta fused by use of the Potara earrings, and is widely accepted as being the strongest character from the Dragon Ball series before Dragon Ball GT. Vegetto, like Gotenks before him was voiced by two actors at the same time. In Japan he was voiced by the seiyū Masako Nozawa (Goku) and Ryo Horikawa (Vegeta). In the US version Vegetto was voiced by Sean Schemmel (Goku) and Christopher Sabat, (Vegeta). The Ocean Group version has Vegetto only voiced by Brian Drummond, the first voice actor for Vegeta.
Appearance
Vegetto is a mixture of both Goku and Vegeta's characteristics. He is approximately 5 feet 8 inches tall, about the same height as Goku. His personality is a mix of the two. He acts cocky like Vegeta, but he had been acting in that way on purpose to accomplish his plan of saving the others, just as Goku had done in the past. Being a whole new being, he refers to his counterparts as separate people as they would address each other, he said, "Vegeta," as Goku would, "and Kakarotto" as Vegeta would, "combined, so I guess that makes me Vegetto."
Vegetto's hair is more inclined toward Vegeta since it firmly stands upwards. However, he has two bangs sticking out like a downward "V" shape, a trait caught from Goku. Vegetto wears two earrings as result from the Potara Fusion, and wears an inverted version of Goku's outfit. The inversion is caused by adopting Vegeta's outfit for the external wear, and using the orange of Goku's outfit for the undershirt. Finally, he wears white gloves and boots in the same style as Vegeta.
History
Goku and Vegeta merging into Vegetto
Origin of the name
The name Vegetto (ベジット, Bejitto?) arises from a combination of the Japanese characters that form Vegeta (ベジイタ, Bejiita?) and Kakarotto (カカロット, Kakarotto?). One can see that the name is formed from taking the "ベ" and "ジ" characters from Vegeta's name, and the "ッ" and "ト" characters from Kakarotto. When translating into English, therefore, the name "Vegetto" uses "Vege-" from Vegeta, and "-tto" from Kakarotto. Because Viz uses the name Kakarrot, however, they extracted the letters "-rot" from Son Goku's Saiyan name, and thus named the character Vegerot (note that the English dub calls him Vegetto, which doesn't make sense given the spellings of the two characters' names).
The Potara Fusion
The Potara Earring Fusion used to form Vegetto is what Rou Dai Kaioshin considered to be the proper way to do fusion, as opposed to Fusion Dance technique. The resulting fusion lasts forever, even if the fused being removes the earrings. The determination of power levels is more complex than simply adding together the power levels of the two individuals. Vegetto has the confidence and fighting smarts of Goku, along with the superior attitude and genius strategical mind of Vegeta; in other words, the perfect fusion. Goku and Vegeta's rivalry somehow made the fusion more compatible, giving them even more power than expected, which was seen when Vegetto transformed into "Super Vegetto". It has been stated that the potra fusion is stronger than fusion dance in the manga, thus making Vegetto more powerful than Gogeta.
Vegetto is born
Vegetto was a fusion formed out of desperation by Vegeta and Goku in an effort to stop Djinn Boo, an ancient and powerful being whose only purpose is to destroy. Because Boo had absorbed some of the Z Fighters, including Gotenks, and was getting more powerful, Goku and the Kaiôshins came to a conclusion that the best hope of defeating Boo was fusion, but there was no time to attempt the fusion technique. As a solution to this problem, the Potara Earrings were given to Goku to save the universe from Boo. Goku then proceeds to Earth just in time, before Boo could destroy it. Goku threw the earring to Gohan so they could fuse, but Gohan failed to catch it. Boo then lost a large amount of power due to Gotenks separating inside him. He then proceeds to absorb Gohan, becoming even more deadly and powerful. Goku is now left with no one that could help him by fusing, but miraculously he senses Vegeta's energy, and quickly transports himself to his location. After some quick persuasion, due to Boo beating them up, Vegeta finally agrees (after being told what fate had befallen his family). Then Goku tells him for the first time that the fusion would be permanent and Vegeta shouts at him telling him that he should have told him that in the first place. They both then wear the earrings giving birth to Vegetto.
Vegetto vs. Super Boo w/Gohan
Super Buu w/ Gohan vs. Vegetto
Boo didn't take the new opponent very seriously, even though he felt a great power from him. After playing around with Boo for a while, Vegetto then decided to turn things up a notch, by increasing his power with a transformation. Boo is stunned to know that Vegetto can become even more powerful than he is now. Vegetto transforms into a Super Saiyan, and calls himself "Super Vegetto". Boo is impressed, but not convinced that Vegetto is stronger than him.
Vegetto then began to completely dominate Boo, rendering his attacks useless. His anger at this caused him to start breaking through dimensions, which, if left unchecked, could have destroyed the universe. Eventually, Vegetto forced his way through a shield Boo put up, which effectively stopped his rage.
With little left to lose, Boo turned Vegetto into a coffee flavored jawbreaker. All seemed lost until candy-Vegetto revealed that he was able to fly around and still attack physically, eventually slicing off Buu's antenna. Boo eventually turned him back after realising that there was no way to hurt Vegetto because of his small size.
After another beating, even Buu's regeneration was starting to fail him. Vegetto decided that it was time to end the battle once and for all. He then gave Boo ten seconds to prepare for death, and told him to do whatever he feels like in that time period. Boo started to panic, and when Vegetto reached nine, he manipulated the antenna that was recently cut off and engulfed Vegetto. The battle was over with Boo coming out as the victor.
Unknown to Boo, however, Vegetto could've easily destroyed him at any given moment yet he toyed around with him. Before being absorbed, he had set up a barrier, so he wouldn't be integrated into Boo. This is because he wanted to be absorbed so as to free all his companions and family members. Thus the reasoning for cutting off the antenna and giving him the free time. Boo then goes on a rampage, and Vegetto is left within him to free everyone. When he entered Buu's body, the magic of the earrings wears off because his stomache breaks them down, and Vegetto become Goku and Vegeta again. Vegeta then threw his earring in Buu's stomach acid, destroying it, so they wouldn't have to fuse again. When facing Kid Boo, they were also given the option to become Vegetto again, but they refused out of Saiyan pride.
Forms and transformations
Vegetto
Vegetto's base form
This is Vegetto's base form. This form is first seen when he is first fused. In this form, he is immensely powerful. At this stage, Vegetto's strength is far greater than a Super Saiyan 3's. He is able to completely match Super Boo w/Gohan in this form. However, Vegetto wouldn't much dominate Boo if he were to sustain this form, as it was shown Boo could've landed a few punches and attack on the Saiyan. The power of the Potara Earrings gave Vegetto far more than enough power, making him unbeatable to Boo. Even at this stage, Vegetto would still be considered the strongest character in Dragon Ball Z. However, he is able to make a transformation and substantially increase his power and abilities. Also note that in the manga, Vegetto directly transformed into a Super Saiyan, calling himself Super Vegetto.
Super Vegetto (Super Saiyan)
Super Vegetto
Super Vegetto was able to transform into a Super Saiyan. In the anime, when he was first fused into a normal state he was already far stronger than a Super Saiyan 3. In the manga he transformed right away. Once he transformed into a Super Saiyan, he became truly unstoppable. His powers soared to unimaginable heights. As a Super Saiyan, he completely dominated Super Boo w/Gohan. After his transformation, he gained a slight increase in muscle, though everything else remains the same, except for features such as: Golden hair, eyebrows, green eyes and golden aura (with occasional surges of blue electricity). Vegetto called himself in this new form "Super Vegetto" (Or "Super Vegerot" in the English manga). Super Vegetto appeared to be well beyond Buu's abilities to defeat, though there was one moment where Super Boo might have been able to win indirectly by destroying existence itself. Super Vegetto hardly exerted himself in battle, and was in absolute control of the fight. Vegetto is generally acknowledged as the most powerful character in Dragon Ball Z and the Dragon Ball manga, possessing the enormous power of both Goku and Vegeta.
Candy Vegetto
Candy Vegetto
After being turned into a coffee-flavoured jawbreaker by Boo so that he can be consumed, Vegetto is still able to fight as a small candy. Some consider this to be (ironically) Vegetto's most dangerous form. Not only does Vegetto retain all of his power, but he is also extremely fast and far too small for Boo to hit. In the dub he calls it his "Pinball Attack". However, while this small size gives him a colossal advantage in battle, he is not invulnerable. Vegetto is unable to use any special abilities in this form, rendering him unable to kill villains like Cell and Boo as long as they can regenerate fast enough, although they could theoretically be beaten to death. This is however, a special ability as no one else possesses it.
