Ep. 97: Namek's Destruction?
Ipinalabas noong Hunyo 26, 1991
Not willing to be beaten, Frieza fires an attack to destroy Namek so Goku will be killed, as the Super Saiyan is unable to stop the attack. However, Frieza held back too much power, since he feared that he would be hurt by the blast, and the planet isn't destroyed. Nonetheless, the blast has destabilized Namek's core, and the planet is going to blow up. (Source: Wikipedia)
