Even though Goku is still a kid, he is very powerful. He is strong, 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. He sports a tail, is able to fly short distance, and carries a magic fighting stick that stretches to incredible lenghts. Goku is very powerful because he is one of the extinct saiyans.
