Tsuru-Sen'nin (Crane Sage) is the older brother of Tao Pai Pai, and master to Tenshinhan and Chaozu. In an early Harmony Gold English dub from the 1980s, he is known as Lord Wu Zu.

He was once comrades with Muten-Roshi and studied under the same Martial Arts school. However, they were defeated by the evil forces of the Piccolo Daimaō and their mentor and sensei Mutaito-sama died after sealing the demon away. Over time, bitterness and resentment began to grow in his heart and he eventually turned away from his master's old teachings and began a school where his hatred of the world began to spread among his pupils.

In the 22nd Tenka-ichi Budokai, he entered his two star pupils, Tenshinhan and Chaozu to counter Muten-Roshi's pupils, Goku, Kuririn, and Yamcha.
