Battle for Zanadon

After brief concern from the Terrakors that the rockslide may have destroyed Compu-Core, Zanadon becomes airborne, and the Protectons try to move it out of reach. While Venturak and Compu-Core monitor city functions, the other Protectons explore various regions of the city. However, when Argus is attacked by Nemesis, he realises that Kontor has opened the city's dome to allow the Terrakors access. Tyrannix and Bront battle in the city's sporting stadium, while Steggor pursues Nara into the medical bay. Defeating Steggor, Nara discovers Venturak, the charade over, preparing to abscond with Compu-Core. No match for both Venturak and Tyrannix, Nara is defeated, and Nemesis and the Terrakors escape, with Compu-Core in their clutches. As the Protectons struggle to even close the city's domes without Compu-Core, the now-airborne Terrastar soars overhead, and begins its attack.
