He's a character of Toriyama's work "Dr. Slump and Arale-chan" who also appears in Dragon Ball (manga and anime). Gacchan is somewhat like a little angel (as a cupid) come out dressed and with wings from a Prehistory's egg, speaking a language that only Arale and Turbo understand. The name Gacchan comes from "Gajira" (Japanese for Godzilla) and "chan" that means, in this case, child. Later in the story, Gacchan will create a second Gacchan, by reproducing himself with a cocoon.

He's one of the guards of the palace of Don Kir (Don Kea), the tyrant of Planet Imegga in Dragon Ball GT series. He usually teams up with Sheela, but they are both easily defeated by Goku, Pan and Trunks.

He's the son of Garlic Sr. who once challenged Kami-sama for the throne of God of the Earth, but was defeated and closed in a Dead Zone. Garlic Jr. looks like a short goblin and appears in DBZ movie #1 "Return my Gohan!! (The Dead Zone)" where he gathers the Dragon Balls and wishes the eternal life. But he's knocked down, just like his father, into a Dead Zone where he's sucked into by the little Gohan who gets angry and starts blasting things. Unlike his father, Garlic Jr. manages to come out and appears again in DBZ (only in anime, not in manga where he never existed) after Freeza's defeat. But once again he imprisons himself in the Dead Zone.

He's a scientist working for Red Ribbon Army. After Goku obliterates the army, he keeps on working to research and create very strong androids, capable of defeating this powerful boy. In order to increase his strength and to live forever, he implants his mind in one of his androids shells, and becomes himself the cyborg #20. He gets his energy the same way #19 does, by absorbing it from attacks and physical contact. He's killed by #17, one of his creature.

He's one of the three Garlic Jr.'s henchmen and appears in DBZ Movie #1 "Dead Zone". Ginger is green and short and later powers up becoming stronger and taller to face Goku. However he's defeated by Goku's Kamehameha.

He's the captain of Ginyu Force, Freeza's special team. Ginyu is by far the strongest of them all believes himself to be, after Freeza, the most powerful warrior in the Universe. But when he arrives to Namek and meets Goku, he realizes he isn't! Ginyu can perform the body change, that's to say he has the power to swap bodies with other people; so he performs his technique on Goku but at the ending... he'll find himself to be a frog!
See Ginyu Force.

The team is composed by five of the most powerful warriors of Universe and it's Freeza's special team. Its captain is Ginyu, the only one who gives Goku some trouble... but he's defeated too as his companions. The Ginyu Force briefly appears in Majin Buu saga too, when, from the Afterlife, its components watch the fight Goku vs Kid Bu.

Gogeta is the result of the Fusion between Goku and Vegeta without the Potara earrings, by doing the Metamoru Dance. This character doesn't appear in the manga but only in DBZ movie #12 "The Rebirth of Fusion!! Goku and Vegeta". At first Vegeta refuses to make the dance because he thinks it's just ridicule to put on these absurd postures. But soon he realizes that the enemy, the very powerful Janenba, is too much strong; so Goku manages to convince him. The first time they try, the two saiyans don't succeed in performing Fusion correctly, because Vegeta makes a mistake in the position of his hand! So, instead of Gogeta, they fuse into Vekuu (Fat Gogeta) a fat and funny character who, in spite of his aspect, is able to hold out against Janenba's attacks for all the 30 minutes of the bad Fusion. When Goku and Vegeta repeat the Metamoru Dance, this time correctly, they fuse into Gogeta. This new amazing warrior (he's already born as a Super Saiyan) easily defeats Janenba with a shining ki ball that disintegrates his body.

This very powerful fusion appears during the last Dragon Ball GT episodes, when the enemy to defeat is the awesome Super Ishinlon ( Super Ii-Shenlong). Unexpectedly it's Vegeta, just turned Super Saiyan 4 thanks to the Brute Waves, who invites Goku SSJ4 to perform the Fusion with Metamoru Dance, because he realizes that, separately, even as Super Saiyan 4, they shouldn't be able to face the opponent. Unluckily this Fusion is very short, only 10 minutes! During this time, Gogeta SSJ4 (called Super Gogeta in TV episodes), has fun to ridicule Super Ishinlon, without giving him the finishing stroke! Gogeta SSJ4 best technique is the Big Bang Kamehameha, but he's able to perform many other attacks.

He's Goku's adoptive grandpa, an old man who finds Goku when, as a baby, he falls on Earth with his spaceship, coming form Planet Vegeta where he was born.

Goku is the real protagonist of Dragon Ball. He's a Saiyan born on Planet Vegeta. But as all the Saiya-jin weak children, he is sent on a another planet in order to conquer it.

His best friend is Trunks and he really enjoys to fight with him. Just like Trunks, he's able to turn Super Saiyan when he's still a child and without a special training, so they both reach the Super Saiyan Full Power level. When peace is on Earth he neglects his training and prefers to look after girls, especially during Dragon Ball GT series.

Gotenks is one of most powerful and funny characters in Dragon Ball series. He's the result of the fusion between Goten and Trunks, performed with the Metamoru Dance, and is able to reach the Super Saiyan 3 level.

This is the camouflage used by Gohan to hide his true identity especially to his classmates at the Orange Star High School of Satan City. It's Bulma the inventor of this costume that is closed into a capsule of a watch: when Gohan pushes a button, the camouflage appears on him. Gohan, dressed as the Great Saiyaman, invents a dance to present himself as the defensor of the justice, but he seems very ridiculous.

He's Chichi's father and is an old pupil of Muten Roshi (Kame-sen'nin): under him he also had trained with Grandpa Son Gohan. Once he even won the Tenkaichi tournament. After his daughter marriage with Goku, he stops to be a warrior and becomes a kind and loving grandpa.

He's the weakest within the five members of Ginyu Force, but has the special capability to manipulate time and space.

He's killed by Vegeta who decapitates him just when Guldo is managing to eliminate Kuririn and Gohan.
See Ginyu Force.

He's one of Lord Slug's scientists. When Slug asks him how long it will take to fix Planet Earth, his answer does not satisfy his leader who kills him for that.

Gohan's pet friend, Higher Dragon appears in DBZ movie #3. During the story he's the only being that manages to calm Gohan down when he's in Ohzaru form. We meet him again in DBZ movies #4 and #5 and during Garlic Junior saga.

He's the terrible monster created on Planet Conuts (Konack) by some warlocks who possessed great dark powers and brought the legendary evil of Hildegarn to life to conquer the whole Universe. The monster was held at bay by Tapion's flute playing and split in two by a priest with the sword from the gods themselves. Then his top half was imprisoned in Tapion's body and the bottom half in his little brother Minosha's and both siblings are separately locked inside two music boxes and taken far away on opposite ends of the Universe, hoping that Hildegarn could not reunite. But a thousand years after, the evil Hoy manages to reunite the two halves bringing the terrible monster back to life. During the fight against Gotenks, Hildegarn even undergoes a transformation. Tapion tries to lock the whole monster in his body playing his flute, but he doesn't manage to check him and at the end it'll be Goku SSJ3 to destroy Hildegarn thanks to only his powerful Dragon Fist "Ryuken".
