Chao-Tzu and Tienshan stayed together throughout the series. They trained together on Kame's Lookout, and fought together against Nappa. Chao-Tzu cleverly pretended to be dead, then clamped on to Nappa's back and tried to send them both to the next dimension. Though he failed, his attack was a noble sacrifice. He ended up being able to train with King Kai at the end of Snake Way in the next dimension.
