Gogeta

Gogeta is the resulting fusion of two highly powerful Saiyans, 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 is famous for his amazing power and speed, and is often regarded as one of the series' most powerful heroes. His fusion counterpart is Vegito. Gogeta is an anime only character, meaning he never appeared in the manga.

Appearance
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. Gogeta also acquires Goku's peach like skin rather than adopt Vegeta's more mild tan.

Fusion Reborn
In Fusion Reborn, Gogeta makes an appearance during the end of the movie. After Goku defeated his first form, Janemba transformed into his Super Form and became too powerful for Goku to defeat. Even with the help of the recently deceased Vegeta, he could not kill the demon. So, Goku quickly taught the Fusion Dance to Vegeta. The Fusion Dance must be performed correctly to create a very powerful symbiotic warrior, so when Vegeta failed to extend his index finger properly 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. Gogeta was unfazed by a full-force punch to the face from Super Janemba. 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.
