Olibu

Olibu is a deceased fighter representing the North Quadrant and next to Goku, is its greatest fighter in Other World. King Kai stated that most of Earth's heroic legends are based off of Olibu's acts of heroism during his life.
After his acts of great heroism on Earth during his lifetime, Olibu was granted access to live and train on the Grand Kai's planet. He was working on his 10,000 years of training when Goku meets him in the Other World. During the Other World Tournament, Olibu beats Chapuchai, and later battles but loses to Pikkon in the quarter-finals.

Later, Olibu makes a cameo appearance, along with Mijorin and Maraikoh, in the movie Dragon Ball Z: Fusion Reborn.

During the Kid Buu Saga, he is seen with another fighter sparring with Yamcha, and taunted Kid Buu along with Pikkon. Olibu's last appearance in the TV series is when he along with hundreds of other fighters watch Goku's battle with Kid Buu.
