Krillin had a brief rivalry with Gokuwhen they first met and trained under Master Roshi, but they quickly became lifelong best friends.[8]One of the most powerful and talented Humanmartial 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. His short stature and baldness (with the exception of when he grows out his hair in the Majin Buu Saga onwards) aid him in his ability to provide comic relief during tense moments. During the latter half ofDragon Ball Z, he largely retires from fighting, opting to settle down with his family instead, becoming the husband of Android 18and the father of Marron.
