As a young boy, Krillin studied martial arts with Goku under Master Roshi. Originally he and Goku were fierce rivals, but now they are best friends. A short, bald warrior, Krillin provides comic relief in tense situations as he tries to keep up with Goku and some of the other more powerful warriors. A good fighter on his own accord, he's always there to help Goku. He can and has saved his friend's life more than once. In fact, Krillin unleashes an incredibly powerful energy blast shaped like a flying disk that can slice through mountaintops. Goku constantly encourages Krillin to have confidence in his own abilities as Krillin learns to be a remarkable fighter--that is, for an earthling. Loyal, courageous and dedicated to his friends, Krillin is willing to fight against the Saiyans even though he doesn't want to die and knows that he can't be brought back to life again by the Dragon Balls. Krillin and Gohan become very close friends through their adventures on Earth and Namek, and Krillin would do anything for Gohan.
