Goku is the main character of DB-Z-GT. When Goku was first introduce he was a nice sayian boy. Although he was sent by his race to destroy earth he hit his head and forgot everything. A man name Gohan (not Goku's son) found him and adopted him. He gave him a DragonBall which starts the adventure off. Well later on in the story Goku grows up becomes even stronger and smarter and learns of his race. Goku later finds out thanks to Vegeta that he can change into other forms of Sayians. He is nice and always looking on the bright side. If you are his arch enemy he will still be nice to you like give you a chance or let you live. Goku marrys Ox Kings daughter CHI-CHI. He has two sons Gohan (named after the man who adopted him) and Goten. He is the first to reach SS1, SS3, and SS4.
Gohan
Gohan is the son of Goku. He is a half Sayian half human. Although human blood is in him the Sayian gets the better of him. He is very smart because of him mom always making him do homework and study. He is also a good fighter. Even though when he is first introduce he is a winer and a loser and geek he still has a big power level. When you makie Gohan mad you better run for it because he can raise his power level so fast. He has many friends in DB-Z-GT Krillin and Trunks, but he mainly like Picallo maybe even more than his own dad... Picallo was the first person to teach Gohan how to fight and Gohan I think looks up to him for that. When Goku dies in Cell Game Gohan becomes the main character. He is the first to become Super Sayian 2. He is the strongest thoughout alot of the series because the bad guys are stupid enough to kill his friends. Gohan later on marries Mr. Satans daughter Videl and has a daughter name Pan.
Vegeta
Vegeta probably one of the most meanist...smartest...stupidest...well just all around everything. He is a true sayian like Goku. He respects no one but himself. He usally only wants to be the strongest of the warriors. He does not care about saving anyone. Vegeta goes the low of the low. He is that guy who would let a child die to just become a super sayian. He is so full of him self he lets Cell become perfect. Vegeta reaches three of the normal sayian stages. He is the first to reach the odd stage Ultra Super Sayian. He has a son and a daughter. There names are Trunks and Bra (ha ha). There mother is Bulma. Vegeta's father was killed by frieze. Vegetas dad was the King of the Sayians and Vegeta would have been the prince. He still calls him self prince just to show off. He thinks he can beat anyone but because of his arogance he gets beat. Vegeta is probably the 3rd most important character in DBZ-GT(No Dragonball for him he was first introduced in Dragonball Z)
Trunks
Trunks is a character introduced in two ways. After the Garlic Jr. Series Freiza comes to Earth the Z fighter are getting ready to fight them but a boy out of no where comes and kills all of freizas crew and freiza. They later find out that he is from the future and he to tell Goku of these androids and a virus. Well then the secret is out that he is a guy name Trunks and that his dad is vegeta and his mom is BULMA! The future trunks fights by the Z fighters side and then goes back to his own time. Bulma while future trunks is still around has baby trunks. He grows up to look like the future trunks he is pretty young so he is friends with GOkus son Goten. Trunks is a good fighter and becomes a Super Sayian at a young age. He reaches SS3 only as a fused person with Goten. The future trunks reaches SS1, USS, and SS2 I think.
Piccolo
Piccolo is a form different from human if you already did ot know that. He is from the planet Namek. He was once one form with Kami called Kamiccolo. Then for Kami to become pure good he had to let his bad out. Well since he wanted to be the gaurdian of earth he did so. An evil form Piccolo destroyed everything he saw. But a little boy Goku stoped him. He flew face first through Piccolos body. When he did so Piccolo spit out an egg. It became the Piccolo we see today. Piccolo wanted to be the ruler of Earth. But once again he had to face Goku. Well right when he was going to face Goku a person called Radizt came. He decided to fight along side Goku. Then after that he would face Goku. Well in that battle Goku died so Piccolo was happy but not happy. Piccolo took care of Gohan while Goku was away. Piccolo then help out Gohan and became a father figure to him since Goku was gone. Gohan grows up with Piccolo's wise. Piccolo is the wises Z fighter of them all. He knows pretty much all of everything. Piccolo forgets or just plain doesn't care about facing Goku anymore. Piccolo is very strong at first but later on becomes weak and is used to die or for wiseness. Piccolo in the Android/Cell Saga becomes 1 with Kami. Kamiccolo is who he becomes but his strenght is easily beat. Piccolo is smart and he knows how to fight and train (take it from Gohan).
Krillan
A former monk Krillan is best friends with Goku. When they first met they were enimies and after a while training with each other they became friends. Krillan has always came in a battle alittle scared but then he risk his life for his friends and earth. He also is the strongest man on earth but his powers are not of a sayian. He has to train not like a sayian that after every fight they become stronger. Krillin in the Android saga fall for Android #18 he then marries her and has a child called maron after Krillins first love. At first Krillin has a bald head but then he later grows out hair in the Boo Saga. Krillin is killed the most out of all of the Z fighters...twice when fighting freiza,then by Tambourine, and then by Super- 17.
Bulma
What to say about Bulma...Well Bulma is one of the first Characters introduced in DragonBall-Z-GT. She was a teenage girl when dragonball happen and a new adult in DragonBall Z and a old adult to old woman to dead in DragonBall GT. Bulma come into DragonBall as a girl who wants to find DragonBalls so she can have one wish. While on her way to find the dragonball she hits a boy with he bike/car. This was a hard hit but the boy was not harmed. This boy was later to be found out as Goku and from then on the adventure starts. Goku and Bulma pretty much are always in adventures together not because they like each other it is because Bulma is ALWAYS looking for the DragonBalls and Goku is defeating the bad guy who is looking for the DragonBalls. Bulma falls for a guy name yamcha and they stay together for a while. Then in DragonBall Z Bulma goes to an adventure to namek. That is the last trip i think she took. Then Bulma breaks up with yamcha and then goes with Vegeta. They have a baby name Trunks who after that Bulma takes care of so that is why she never went on any other adventures. Then in GT Bulma and Vegeta are kind of more in love and Bulma helps make a system for Vegeta to go into the next form of Super Sayian (4). Bulma then becomes old like everyone else and dies later. The odd thing about Bulma is that she acts like an air head but really is a geneius....?
Profiles for Goten, Cell, Majin Boo, Chi-Chi, and more coming later.
