That's what sustains him. His grandfather's wisdom, and about 200 pounds of food a day. He eats like a giant! He is a peaceful, good natured, honest, protective, and trusting 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 every villain's ultimate nightmare!

When the Saiyans arrive, it is a total shock in more ways than one! Not only does Goku meet his deadliest foe ever--one that is more powerful than he is--he learns the mysterious secret of his own past: he is a Saiyan formerly named Kakarot sent to Earth as a baby to grow up and destroy the planet as he went along. Fortunately, when he was discovered in the wild as an infant and raised by a peaceful old wise man, his life was changed forever. One day, when he was going with his grandfather, he accidentally fell down on his head and then from later on, he was a good kid, pure-hearted and was fighting for good!

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. Sometimes he is too trusting but Goku is always looking for the good qualities in people and can often find a spark of good when others don't see it.

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 pieces of energy from all sources on the planet, concentrates it on 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.
