Goku (Son Goku) is the main protagonist of Dragon Ball metaseries created by Akira Toriyama. He is the husband of Chi-Chi, Gohan and Goten's father, and the grandfather of Pan. Goku is a defender of the Earth and informally leads the Z Warriors. Throughout his life, he trains hard and strives to be the greatest warrior as possible, while simultaneously using his incredible strength and skills to keep the peace. These qualities make him the perfect example of a hero, but not necessarily the perfect model, because of his lack of education.
Gohan (Son Gohan) is the first son of Goku and Chi-Chi. He is the eldest brother Goten, Videl's husband and the father of Pan. Gohan is the first hybrid (half man, half Saiyan) to be published in the series. He is named after Goku's adoptive grandfather. His name is a homophone for gohan, the Japanese word for "cooked rice," which also refers to meals in general. Mandarin reading is the homophone of wûfàn, which means lunch. Gohan is a shy and studious intellectual, and as a child, he lacks the fighting spirit of the Saiyan. He must use his half-breed Saiyan incredible and emotional potential reserves to protect those he loves, becoming one of the most powerful Z fighters. As an adult, he gives up his superhero duties and instead uses his mind as a leading scholar of the Dragons.
Vegeta (Vegeta), or Prince Vegeta is the prince of the fallen race Saiyan and Goku's rival. He is the husband of Bulma, Father of Trunks and Bulla, ex-brother of Tarble, and great grandfather of Vegeta Jr. Apart from Goku, Gohan, and Piccolo he is easily one of the characters most prominent in the series, receiving more character development after being introduced to a number of other characters. He was once a young member of the Saiyan Army for the organization of planet trade, but after the extinction of his race, he works with Nappa and Raditz, directly under Frieza. He later joins the Z Fighters while fighting against their sides on Namek, and returns to Earth with them too, where he remains for the rest of his life. Like almost all Saiyans, Vegeta's name is a pun out of vegetables, and in this case, most of the word itself, "vegetable".
Future Trunks (Mirai no Torankusu, lit. Trunks of the future) is the son of Vegeta and Bulma.
Future Trunks is the first one that readers and / or viewers ever seen in manga and anime. Trained by Gohan in an alternate future, Future Trunks travels back in time to seek help from Goku to prevent the androids to ravage the world as they did in his dark future. Future Trunks is a loyal and uncompromising warrior, and maybe a bit arrogant sometimes. He inherited the can-do attitude of his mentor, and the brash confidence of his father (although he has shown less of it at different times, but most of it has been exposed during his fight against Freezer). He wields a sword of unknown origin and wears a Capsule Corporation jacket.
Trunks (Torankusu) is the man / Saiyan hybrid son of Bulma and Vegeta, and later, the elder brother of Bulla. In the English dubs of the Budokai and Budokai Tenkaichi series of games, he is called Kid Trunks, to make a difference with his alternate future counterpart.
Goten (Son Goten) is the second and last child of the protagonist of the series, Goku and his wife Chi-Chi, making him a hybrid of human and Saiyan. Goten was created in the series to replace Goku as Akira Toriyama wanted to retire Goku from the series, allowing Gohan to take command. However, Toriyama was forced to bring Goku back when the fans disapproved of the decision to replace him. He is the younger brother of Gohan, and Trunks' best friend.
Gotenks (Gotenkusu) is the powerful result of Trunks and Goten using the Fusion Dance technique.
Vegito (Bejitto, Vegetto) is the result of the extremely powerful fusion between Goku and Vegeta by the use of earrings pots. His voice is a voice that contains both Goku and Vegeta's voice. Vegito is considered the most powerful character in the Dragon Ball world, thanks to his immense power and speed, and is often considered the most powerful person in the entire Dragon Ball, Dragon Ball Z and Dragon Ball manga. His counterpart is Gogeta Fusion Dance. This article is inspired from the Dragonball Wikia
