Grandpa Gohan
Son Gohan Ojisan "Grandpa Gohan"- Born in the year 658, Gohan was a martial arts master who basically lived a hermit's life in Mount Paozu. He was trained by the Muten Roshi at the same time Gyuu Maou was also being trained by him. Gyuu and Gohan knew each other very well. Gohan was the man who wielded the legendary Nyoi Bo, a powerful extending staff. Gohan found the young Saiya-jin baby Kakarroto in the forest of Mount Paozu he named him Son Gokou. He raised Gokou and taught him martial arts, he and Gokou lived happily together. However, one unfrotunate evening, Gokou looked up at the full moon and transformed into his Ohsaru form. Gohan was no match for the beast and was unfortunately crushed by him. Gokou gets to meet up with Gohan's spirit later in the series though. Gohan is actually the last competitor in Uranai Baba's line-up up foes who Gokou faces off against. Gokou doesn't even know that it's his grandfather's spirit, (because he's wearing a cat mask), until after the match. Gokou meets up with his grandfather one last time in the anime at the end of Dragon Ball at the border between the underworld and the Earth.
