As Tien gets beaten up by Nappa, Chiaotzu latches on to Nappa's back and explodes. As the smoke clears, it is discovered Nappa has only been slightly wounded by Chiaotzu's attack. Piccolo and Krillin do their best against Nappa, but the Saiyan is much too strong for them. Using all the power he has, Tien fires an attack to avenge his fallen friend, but it is still not enough to stop the rampaging Nappa.
