Master Roshi is a venerable martial arts master, also known as Master Roshi or Kame Sennin . He enjoys an undeniable reputation in the martial field because of his technical knowledge and in particular for having invented the legendary Kamehameha attack.
This wise man spent several years on a desert island with a turtle as his only companion, which earned him the evocative nickname of "turtle hermit". The pink house he erected there - the Kame House - remains to this day a place where his friends and disciples gather. Although it may seem incongruous, it should be noted that this elderly man has impressive physical strength.
