A short, hairless (for most of the series) warrior monk, loyal Krillin provides comic relief during tense moments. Like Chiaotzu, Krillin doesn't have a nose. He is a good-natured, outgoing and competitive martial artist. His only true vice seems to be his interest in women, though as the series progresses, his intentions lean more romantic, and in dangerous situations, he sometimes despairs about possibly dying unmarried. One of the most powerful and talented Human martial artists on Earth, Krillin is courageous, a faithful ally and good-natured. He is a prominent Z Fighter, despite usually being overpowered by the major enemies.
Once a fierce rival of Son Goku, he quickly became his best friend while training under Master Roshi. He also is close to Goku's son, Gohan. He eventually marries Android 18 and settles down, having a daughter named Marron.
