Krillin (クリリン, Kuririn) is the best-friend of Goku and a Z Fighter who is short in height and bald (with the exception of the Majin Buu Saga onwards) and provides comic relief during tense moments. 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.
Once a fierce rival of 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. Krillin is known for being very cunning during his fights often relying on tricking his opponents to defeat them.
