Terrakors have a head start, and stage a flash flood to wash the Protectons away. Attack of the Rock Creatures - Boltar's bulk shields the Protectons from the flood, and they continue on their search for the crystals. Both races are captured by a bizarre race of rock creatures, who also feed on the crystals. The creatures separate the humans from their Robotix partners and imprison them in their subterranean realm within a volcano. As the humans watch, they see the rock creatures smelt their ship (it is unexplained how the ship that was back at the Protectons ended up being where everyone was being held hostage), and it soon becomes apparent that the Robotix are to share the same fate, with Jerrok going first. All for One - Held captive in a pit by the rock creatures, the humans are threatened by a monstrous many eyed feline, which Exeter uses to escape. After snatching a Siliton crystal, he recharges Jerrok, who saves himself and holds off the rock creatures while the humans recharge the other Robotix and interface with the nearest ones they can find. This leads to some unstable partnerships, as Argus ejects Gaxon from his control capsule for forcing him to kill the rock creatures. Goon and Bront fuse into a battering ram that smashes open a path to freedom, but when Tyrannix opens fire on the rock creatures, he triggers the volcano, forcing all the Robotix and humans to partner up correctly to most efficiently save both themselves and the rock creatures from destruction. The rock creatures lead the Protectons to safety, but the Terrakors manage to survive on their own, and once again attack Zanadon, as Tyrannix buries the city in a rockslide. 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
