Krillin
	Krillin is one of Goku's best friends.  He first appears early in the first episodes of the original DB series.  He, along with Goku, trained with Master Roshi at a very young age.  He has always been faithful to Goku and in the DBZ series he becomes really good friends with Gohan.      Krillin is definitely not one of the stronger characters in the series.  As a matter of fact, he's probably one of  the weakest character in the series.  But what makes him such a popular character is his comic relief, as he adds a lot of it in the series.  He always seems to be at the wrong place at the wrong time and always pays for it.      Later in the series, Krillin marries android 18 and has a daughter. He also grows hair later in the series (as most know, he's bald throughout most of the series).
