Master Roshi is over three hundred years old and enjoys reading, watching TV and using the internet mainly for adult sites. He is a little pervert who constantly watches wide-thigh aerobics on television or looks at dirty magazines in his spare time. He even accepts a bribe from Bulma, to show him her panties in exchange for a Dragon Ball (and got a very big surprise, as Bulma unknowingly was not wearing any panties when she exposed herself). Master Roshi often makes humorous sexual advances on any beautiful woman he can get close enough to, usually Bulma or Launch in Dragon Ball or Maron and Android 18 in Dragon Ball Z. He firmly believes that he is the ultimate stud and very cool, even though his fashion sense and mannerisms seem to be at least a few generations out of style. Dedicated to training his students in the way of the Turtle School, he remains the most powerful martial arts grandmaster of all time.
Master Roshi: Do your legs hurt? Cause you've been running all through my dreams!
Mermaid: Pardon? ... I don't have legs.
Master Roshi: [awkward laugh] So, you're a mermaid, are you?
Master Roshi: [thinking to himself] I knew there was something fishy about this ...
[looks at the mermaid's skimpy top]
Master Roshi: [thinking] I guess i can still try with her human half ...
Master Roshi: Well, I'm like a turtle and you're part fish, so what do you say you and me go inside and learn more about our species?
