Goku (Son Goku), born Kakarot. Is a male Saiyan and the main protagonist of the Dragon Ball series. Goku is a Saiyan originally sent to Earth as an infant. However, an accident alters his memory, allowing him to grow up to become Earth's greatest defender and the informal leader of the Dragon Team. He constantly strives and trains to be the greatest warrior possible, which has kept the Earth and the universe safe from destruction many times.

​

Essentially, Goku is the spitting-image of his father, Bardock, possessing the same spiky black hairstyle, dark-coloured eyes, and facial features. However, he has softer eyes, a kind demeanor, and a lighter-pale skin complexion from his mother, Gine. Goku's most distinguishing physical characteristic is his hair. He has 3 bangs hanging to the right of his forehead and 2 bangs hanging to the left. His hair also stands up in the front with 4 spikes and 3 bangs in the back later in the anime his front spikes become 5 and his back spikes become 4. Goku was born with the signature tail of the Universe 7 Saiyans, which was long and prehensile with brown fur. While occasionally having it removed and later regrew it, by his late teens, it was permanently removed by Kami (to prevent his Great Ape transformation so Kami could safely bring back the moon).
