Goku begins his life on the Saiyajin Home world of Planet Vegeta. He is
born to a low class saiyan named Bardock who was later killed by Frieza. Born under
the Saiyajin name Kakkarrott, Goku only had a power level of two when he was born
which was considered to be a low fighting potential. Because of this, he was to be sent to
another planet in order to destroy it. Goku’s constant crying as a baby beside of another
Saiyajin child, Brolli, caused an intense hatred for Goku in the evil Saiyajin. Finally,
right before Frieza destroyed his father and Planet Vegeta, Goku is sent in a space pod to
Earth.
Bardock Special

When Goku arrives on Earth, his space ship crash lands on a forested
mountain and Goku is found by Grandpa Gohan. Grandpa Gohan takes gives him the
name Goku and raises him. Goku was wild as a child, but an accident where Goku falls
from a cliff and bumps his head, changes him into a calmer child.
Goku begins his training in the martial arts under Grandpa Gohan. He
meets his best friend Krillin and ends up continuing his instruction with others including
Master Roshi.
Goku goes in search of the dragon balls and meets Bulma for the first time
during his travels. He has encounters with the Red Ribbon Army and Dr. Gero’s
creations.
Goku transforms into his Oozaru form and accidentally steps on Grandpa
Gohan. To prevent him from causing more destruction, Goku’s tail is removed.
Dragon Ball Z

Dragonball Z begins when Goku, who is married to Chi Chi, goes to visit
his friends at Roshi’s island. He has had a child in the time between Dragon Ball and
Dragon Ball Z and has named him after Grandpa Gohan. After he introduces his son,
Gohan, to Bulma, Krillin and Roshi, a mysterious alien arrives and reveals that he is
Goku’s brother, Radditz, and that Goku is from the Saiyan race. Goku is forced to fight
Radditz to rescue his son. During the fight, Goku, who is wearing the orange gi that is
seen through most of the series, removes his weighted clothing. He removes the
weighted boots, armbands and shirt before confronting Radditz with Piccolo.

During the fight with Radditz, Goku is able to restrain him long enough for
Piccolo to blast the evil saiyan with the new attack he had been developing. Piccolo hits
Radditz with a huge blast from his special beam cannon, or better known as his
makankosappo attack. Unfortunately, the blast also kills Goku. In the afterlife, Goku
must travel down snake way in order to train with King Kai for the upcoming battle with
the Saiyans. Goku successfully completes his training with Kai and learns a new attack,
the Sprit bomb or Genki-Dama Goku has a halo over his head and must be wished back
to life with the dragon balls.

Goku is wished back to Earth and is able to defeat Nappa and Vegeta. He
asks Krillin to allow Vegeta to live and Vegeta escapes. Goku recovers in the hospital
while Bulma, Krillin and Gohan all leave to retrieve the Namek dragon balls in order to
wish their friends that were killed during the battle with Nappa and Vegeta back to life.
Goku later follows them in order to confront Frieza. During the battle with the evil
alien, Piccolo is injured and Krillin is killed. This pushes Goku anger to the point that he
makes his first major appearance change into a Super Saiyan. Goku’s hair changes from
black to golden yellow and his eyes change to green. In this form, Goku is able to defeat
Frieza but is trapped on the doomed planet Namek.

Planet Namek explodes and everyone thinks that Goku has perished. The
Namekian dragon is summoned again and he is wished back. It is then that Goku’s
friends learn that he is alive. Goku returns to Earth after Frieza and King Cold arrive and
are defeated by Future Trunks. His friends learn that he was able to leave the planet in
on of the Ginyu force’s space pod. He crashed on a planet Yardrat. The people of the
planet are friendly and teach Goku a new technique, Instantaneous Movement (or the
yucky FUNi dub, Instant Transmission). Goku is wearing clothing from the planet when
he arrives back on the Earth.

Goku is warned of his future death by Trunks and is given an antidote to
counteract the heart disease that will affect him. Unfortunately, Goku shows no signs of
the illness and does not take the antidote. Goku, in his Super Saiyan form, begins his
fight with Android 19 and is struck with the disease suddenly. Luckily, Vegeta steps in
and saves Goku, who is rushed home by Yamcha to be given the medicine that will save
his life. It looks as if Goku is not going to recover but the antidote finally works. Goku
is seen again training this time with his blue shirt on.

After his recovery, a new menace has arrived on the planet. Cell, another
android created by Dr. Gero has emerged and is absorbing many humans to increase his
power level enough to fight Androids 17 and 18. Cell must absorb them both to reach is
“perfect” form. Goku and Gohan enter the Room of Spirit and Time, while Vegeta and
Trunks fight Cell. While training, Goku wears one of the modified Saiyan uniforms that
Bulma created.

Cell is allowed to absorb Android 17 and 18 by Vegeta and reaches his Perfect
form. Vegeta is no match for him and Trunks steps in to fight. After seeing that Trunks
new Ultra Super Saiyan form is too slow to be a challenge to him, Cell proposes a
tournament that he calls the Cell Games. He gives thee Z fighters nine days to prepare.
During this time, Goku and Gohan both relax and continue their training by remaining
in their Super Saiyan forms.

During the fight with Cell, Goku again wears his orange gi. Unfortunately,
during the battle, Cell tries to blow himself up in order to destroy the planet. Goku uses
his Instantaneous Movement technique to take Cell to King Kai’s planet where he blows
it up and kills everyone there. Goku is now dead again and can not be wished back to life.
Goku again has the halo and is allowed to fight in the afterlife tournaments.
NOTE: Goku’s Super Saiyan form 3 was attained in Movie 12 during his fight with
Janemba. During the series he transforms into Super Saiyan Level 3 when he fights
Buu.

A few years go by and Gohan is now attending High School. Another
Tenkaichi Budoukai takes place and Goku is granted a day on Earth in order to
participate. Goku retains his halo and his Orange gi. During the tournament, the Z
fighters learn that a new villain, Babidi, is planning to release Buu, a powerful fighter
that lives to destroy the Earth. Goku, Gohan, Vegeta go to fight the evil being but Bebidi
is able to make Vegeta his slave and is able to use his power to release Buu. Goku fights
Buu and reaches Super Saiyan form 3. Goku’s hair gets extremely longer and his
eyebrows disappear. He is defiantly more powerful but is unable to sustain this form for
long.
Dragon Ball GT

Ten years go by and Pilaf, on his quest to rule the world, has gathered the
Dragon balls and summons the eternal dragon. He is about to make all his wishes come
true when he accidentally wishes Goku was a kid again so that he would be easier to
defeat. His wish is granted and Goku is transformed into a child again. This causes the
series to begin as Goku, Trunks and Pan must travel the Galaxy in search of the Black
Star Dragon balls.

After Goku gets back to Earth he must fight a new menace
that followed them back to the planet. During the search for the Black Star Dragon Balls, the
trio arrive on Dr. Myuu’s planet. One of Dr. Myuu’s projects is the sole surviving
Tsufuru-jin, who, seeking revenge on all Saiyans, follows them back to Earth. When he
arrives, he takes over Vegeta’s body and Goku is forced to fight him. Goku must transform into his Super Saiyan 3
form to fight Bebi Vegeta. Unfortunatly, he is not strong enought to defeat him.

During the fight,
Goku transforms into Golden Oozaru and then attains a new level, Super Saiyan form 4.
In this form, Goku is able to defeat Bebi, who leaves Vegeta’s body. Goku also uses this
form during the Evil Shenlong series.
