Van, Thomas, Irvine, and Zeke work on improving the Liger's attack boosters. Moonbay and Fiona watch them for a while, and Fiona senses something. Then Fiona and Moonbay go to bed. Meanwhile, Hiltz stands over a huge tank and says that the Zoid is almost ready to wake up. The only problem is that if the Zoid core's temperature keeps increasing at that rate, it will only be a matter of time before the Guardain Force detects the heat signature, unless Fiona is already aware of it. In a cave, Hiltz talks to the Dark Kaiser (might be Prozen). Hiltz explains how they were able to fuse the cores of two scorpian Zoids together to form a more powerful Zoid and it's almost time for it to awaken. Raven and Shadow come and then leave without saying anything. Hiltz smirks as Raven walks away. Later, Raven and Shadow look at the stars and Raven vows that he will kill Van.

The work on the Liger is done. Thomas and Irvine argue, and Van fails to stop them from fighting. There are Gun Snipers at that base with special bullets that can penetrate shields. Fiona dreams about the Death Saurer, and feels the evilness of the Zoid in the tank. She gets up and searches for something using a computer while Thomas and Moonbay watch from a distance. Fiona finds what she was looking for and runs off to find Van, who isn't at the base at the moment, so she gets in a Pteras and flies off. Fiona and Thomas decide to follow her. Raven and Shadow watch Fiona fly away and then get into the Geno Breaker. Van gets back to the base and Irvine tells him about Fiona. He wants to go look for her, but then the Geno Breaker approaches the base.

Fiona lands somewhere and Thomas, in the Dibison, and Moonbay, in a Pteras, get there too. Fiona has picked up a Zoid core signature that's temperature is the same as the surface of the sun, the strongest ever. Hiltz watches them and laughs, since they're too late to stop him. A huge Hammerhead-like Zoid appears and then a huge tank rises out of the ground. Hiltz announces the beginning of the end of the world. Meanwhile, Irvine and Van battle Raven, who's shield gets penetrated by the Gun Snipers' bullets. Hiltz says that the Zoid in the tank is the most evil Zoid of legend, the bringer of death, messenger of doom, the Death Stinger, and the tank opens to reveal it. Thomas fires a megalo max at it, but there's no effect. Hiltz explains that the ancient Zoidians made two ultra-violent scorpian Zoids to contain the Death Saurer. He fused the cores of the two Zoids together to make the Death Stinger. Hiltz orders the Death Stinger to fire a huge charged particle beam, which misses Thomas, Fiona, and Moonbay.

Hiltz's target wasn't Thomas, Fiona, or Moonbay, but Van. Raven and Van are still fighting when they see the huge beam approaching. Van manages to get away, but Raven gets knocked around a bit by the edge of the blast. The Death Stinger is loaded onto the Hammerhead-like Zoid, which flies off. Fiona figures out that Hiltz was aiming for Van and tries to contact him. Meanwhile, Raven falls out of the damaged Geno Breaker and Shadow ejects. The Organoid is a burning red color and Raven runs to him, but Shadow turns to stone. Raven cries for his Organoid.
