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.
