|First Appearance||Dragon Ball|
Son Goku, addressed only as Goku in most English dubs, is a fictional character from the Dragon Ball series created by Akira Toriyama as the main character and protagonist for the Dragon Ball anime and manga series. Goku is introduced as a weird, monkey-tailed boy who is abnormally strong for even an adult. In Dragon Ball Z, he is revealed to be a descendant of an extraterrestrial warrior race called the Saiyans. Goku appears in all Dragon Ball Z movies and briefly in the Dragon Ball Z special, Bardock: The Father of Goku. His Saiyan name given to him by members of his race as we learn in Dragon Ball Z, is Kakarot.
Goku, being a typical full blooded Saiyan, appears with black hair and black eyes in his regular state. He is easily recognized by his rather unusually styled hair that sticks out in multiple directions.
As a Super Saiyan, Goku's hair turns to a blonde color, and his eyes go from black to turquoise. As a Super Saiyan 2, the basic characteristics remain. His hair slightly changes in style, and in addition, lightning currents appear when he has his aura activated. As a Super Saiyan 3, Goku's hair drastically increases in length, and his eyebrows mysteriously vanish. In Dragon Ball GT, Goku discovers another transformation, Super Saiyan 4. This stage is noticeably different from the other Super Saiyan forms, as Goku's hair doesn't turn golden blond, but remains black and extends down to his back and over his shoulders. In addition, unlike the traditional physical characteristics of a Super Saiyan, Goku grows pinkish-red colored fur from the waist up and around his chest and abs, ending at his hands, which makes him appear like a miniature Oozaru.
Goku was only seen once with a Saiyan uniform when he trained in the hyperbolic time chamber with Gohan his son, preparing for the Cell Games. Originally, Goku appears in a blue uniform in Dragon Ball, but he later starts wearing orange uniforms in the latter stages of the series, and throughout most of Dragon Ball Z. In addition, Goku is initially seen wearing outfits with his training masters' symbols, which are actually words written in Kanji, on the back. The first symbol is Master Roshi's "kame" symbol, which translates into "turtle". The second is the symbol of King Kai's, which is Kanji for "kaio" and translates into "world king". The third symbol he is seen using is his own trademark which is the Kanji for "Go", which means "wisdom", or "enlightenment". From the Android Saga on and forwards, Goku is no longer seen wearing symbolized combat uniforms. At the end of Dragon Ball Z, Goku drops the orange outfit and adopts a new one which consists of a turquoise shirt, pink-red wristbands, dark blue-green pants, a white sash, and black shoes with orange leg wrappings. In Dragon Ball GT, Goku wears a similar outfit, only this time it consists of a blue shirt, pink wristbands, yellow pants, white sash, and unchanged from his previous outfit, black shoes with white leg wrappings. However, as a Super Saiyan 4, Goku's outfit changes slightly, wearing no shirt (no need because most of his upper body is covered in fur), a blue sash, blue wristbands, and black shoes with blue leg coverings. The only article of clothing that remains unchanged is the yellow pants.
Goku has a very large family due to the Alternate Timeline, and even without it, his family is very large. As he is the main character of the entire series, his family's continuation is necessary in order to keep the family going.

During Dragon Ball Z, Goku was often thought of to be the best warrior, as well as the Earth's only hope. He did get help from many of his friends, known as the Z-Fighters, when it came to saving the world.
During the Saiyan and Namek Sagas, however, the Z-Fighters were almost all killed. This forced Piccolo and Goku to work together to gather all seven Dragon Balls and revive their friends. After all of his friends were revived, the Z-Fighters went out on missions to save the world, stopping enemies such as Cell and the Androids.
Being a member of the Saiyan race, Goku has a generally higher Power Level than normal human beings from Earth. This makes it easier for him to manipulate his own energy and sometimes manifest it into a concentrated ball or blast which can inflict damage to his opponent. Goku also has achieved heightened power and speed. Throughout his adventures he has developed specific techniques that he has used during fights. Some of these he continued to use consistently until the end of the series while others became less important and generally neglected.
 Saiyan Transformations
Because of his Saiyan heritage, Goku can transform into a number of different forms exclusive to descendants of his race.
- When his Saiyan tail is intact, Goku can transform into an Oozaru by looking at the full moon or an artificial copy of one. In Dragon Ball GT, Goku can transform into a Golden Oozaru, which is a stronger variant of an ordinary Oozaru. The trigger from Oozaru to Golden Oozaru is unknown, as it was not mentioned in the anime. </font>
- Super Saiyan
- Goku's Saiyan blood allows him to transform into a Super Saiyan, a form in which his strength and speed is increased fifty fold. Unlike the Oozaru transformation, it doesn't require a tail or the action of looking at the full moon. Furthermore, Goku retains his human-like form, however bulkier due to his increased strength. As a Super Saiyan, Goku's hair stands upright and turns golden blond in color. In addition, his eyes become keener and the color of his pupils turn turquoise. Throughout Dragonball Z and GT, Goku develops his Super Saiyan power further and is able to transform into a Super Saiyan 2, Super Saiyan 3, and lastly Super Saiyan 4. Each of these heightened Super Saiyan forms have their respective characteristics, but they all share the common yellow aura.
