Goku

Goku is the star and main protagonist of the incredibly successful anime Dragon Ball Z. He one of the last surviving members of the Saiyan race, an extraordinary alien race with awesome powers. He takes advantage of these powers throughout the series, even becoming a Super Saiyan.

Concept and Creation
The story of Dragon Ball Z was created by Akira Toriyama. Son Goku was based off Son Wukong, from the Chinese story Journey to the West. Originally the two characters were very similar, but as the series went on, Goku lost his fantasy element in return of science fiction. Goku's other inspirations were Tanton and Tongpoo, both of which were made by Akira.

Appearance
The most notable trait of Goku's appearance is his spiky hair. In the beginning of the series, it was said that this was because he never washed his hair before in his life. When it was revealed he was a Saiyan however, it was changed to be a genetic trait. He was born with hair that way, and a Saiyan's hair always stays the same. Goku's other signature appearance is his gi. This gi is normally a light orange, and is worn over a blue undershirt. In most recent material, he has the turtle kanji over his heart. Other times it is also on the back, or just not there at all.

Personality
Goku is also known for his overly cheerful personality and tenacity. He does not want to harm others, but is still excited to fight if it must be done. He will not kill enemies unless they have no chance of going legit. When he had defeated the overlord Frieza, Goku offered him energy so he could escape Namek. This kindness can sometimes have consequences, such as in that situation. Frieza turned on him, and tried to destroy Goku.

Like all other Saiyans, he enjoys to eat large amounts. He will devour entire buffets in minutes, and then ask for more. Eating does not make him any fatter or less fit, but instead gives him energy. He can most likely eat as much food as Monkey D. Luffy or Toriko.

Biography
Born as Kakarot, a member of the barbaric Saiyan race, Goku was sent of Planet Vegeta in hopes of taking over Earth. Goku was sent off the planet minutes before it was destroyed by the tyrant Frieza. On Earth, he was adopted by Grandpa Gohan, and became a peaceful and fun loving child.
