Gravion faces off across from the Zeravire whilst Sandman and his guests watch on. The President orders the navy to launch the particle projection cannon at the Zeravire. Mizuki wonders who is piloting the G-Shadow, no one knows. Eiji tries to escape the Gravion but realizes he cannot just walk out. The particle projection cannon hits the alien to no effect. Gravion is smashed into its constituent pieces, and Toga and his Gran Kaiser sink to the bottom of the ocean. The Zeravire stops attacking and builds a cocoon around itself. Sandman expels the world leaders from his castle. Eiji meets Sandman and demands his sister back. Sandman explains the letter he sent was a fake to get Eiji to come to the castle to pilot the G-Attacker, as Eiji, like his sister, has a G-factor enzyme in his body that allows him to adapt to changes in gravity. Mizuki explains that Ayaka is missing since training. The Zeravire breaks out of its cocoon, ready to attack again. After some taunting, Eiji agrees to fly the G-Attacker. The Zeravire has evolved to be stronger than before and the Gravion is powerless against it. Using the Graviton Pressure Punch, Gravion is finally able to inflict damage on the Zeravire. Gravion fires its Graviton Arc and obliterates the Zeravire.
