Transform into Super Saiyan
Taught Kung-Fu by his late Grandfather who raised him out in the wilderness, Goku is very strong, very agile and virtually fearless. He'll take on any fight no matter what the odds are if he thinks that someone has been wronged. And he'll usually win. That's because Goku is not a typical eight year old. He is able to fly short distances and carries a magic fighting stick that stretches to incredible lengths.But Goku is more that just a good kid with cool hair and a great karate kick. He's a little naive which can really annoy Bulma at times!
But no matter how far from his home Goku travels, the spirit of his grandfather is always with him, providing him with a wealth of knowledge that he can call upon in times of need. It's Goku's quotes of his grandfather's views and observations about the world and life in general that keep him anchored as the temptations and intrigue of the world swirls around him.
That's what sustains him. His grandfather's wisdom, and about 200 pounds of food a day. The kid eats like a horse!When Goku grows up, he is still 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 later episodes) 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. A near-fatal head injury scrambled his programming and instead of growing up to become a destructive super-warrior, he became innocent and pure of heart, 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.
Goku's power level changes rapidly rising from a 330 level in the beginning peaceful episodes to 5000 after training with King Kai to 8000 when he is angry to 21000 when doing the famous Triple KAIO-KEN. And all of this is before his Super Saiyan stage! To further aid him, Goku still has the famous Nimbus Cloud and Power Pole.
Goku has many more adventures fighting Freiza on planet Namek, where he becomes the first Saiyan to transform into a Super Saiyan in 5000 years!
Several years after the Frieza Saga, Goku contracts a life threating virus. The Trunks intervenes and gives goku the antidote. Goku sacrifices his life to kill Cell by teleporting himself and Cell to King Kai's planet.
In the afterlife, Goku fights in the Outer World tournament and wins against a powerful fighter named Pikon from a different planet in the galaxy. Goku is then granted one day of life on Earth, which he uses to fight Buu and his henchmen.
