Roshi
Master Roshi is the oldest member of the Z warriors that also is one of the most experianced in Martial Arts.
He is a weird, down to Earth guy who will never underestamate his enemies. He trained many of the
Z warriors. He also likes to watch the women's exersize show and read the same type of magazines.
Family
 I don't know a lot of Roshi's family. I know he has great ancestors but I'm not quite sure of their names.
Besides that the only family he has is the gang at Kame-house, The place where he lives.
 History
    In the Dragonball he trains Goku, Krillin, Tien, Yamcha, Choutzu and some others but mostly those.
Training is pretty much everything he does but in the past he wins one of the Martial Arts Tournaments.
