Goku is the hero of Dragonball Z. He is a peaceful, good-natured, honest, trusting, and protective
soul. He is also the most powerful warrior on Earth and the first to become a Super Saiyan
in over 1000 years. Having honed his skills and strengthened his spirit to a level never
achieved by any being on Earth, Goku is able to fly, shoot energy beams from his hands, move at
incredible speeds and, when in a pinch, power-up to a fighting level so high it creates an energy
aura around his body and makes him turn blond with green eyes... becoming in effect a walking
nuclear war. Goku hasn't learned these skills just for fun, his life is forced down this path as
he battles the evil Saiyans in the final battle to save the Earth.

When the Saiyans arrive on Earth it is a shock in more ways than one. Goku finds out
the mysterious secret of his own past: he is Saiyan formerly known as Kakarot who was sent to
Earth as a baby with the mission to conquer the planet. Luckily for Earth a near fatal head
injury "scrambles" his programming and instead of becoming a destructive super-warrior he
becomes an innocent pure-of-heart defender of Earth. Goku was raised by a peaceful, wise old
man named Gohan, after whom Goku later names his first son. Goku is always there to help his
family and friends and he is very protective of them. If he has a weakness, it is his trusting
nature.

Goku has many powerful fighting techniques including the powerful Kamehameha Wave and
the Kaio-ken which he learns from King Kai. His last and most powerful weapon is an immensely
powerful energy ball which garners energy from all sources on the planet, concentrates it into
one sphere, and then releases it in one mighty swoop. This ball can be used only once and must
be guided carefully for it can destroy the planet if used inappropriately.
