Ep. 2: Eiji pilots the G-Attacker to defeat the evolved Zeravire threatening the world leaders.

Sandman watches as the Zeravire withstands the navy's particle projection cannon. The Gravion is destroyed, sinking Toga and Gran Kaiser, while the alien forms a protective cocoon. Sandman expels the world leaders and reveals to Eiji that his sister Ayaka is missing. He explains that Eiji possesses a G-factor enzyme, making him the only one who can pilot the G-Attacker. After initial hesitation, Eiji agrees to fight. The Zeravire emerges from its cocoon, significantly stronger than before. The damaged Gravion proves ineffective against the evolved enemy. However, utilizing the Graviton Pressure Punch, the Gravion finally inflicts damage. It concludes the battle by firing the Graviton Arc, completely obliterating the Zeravire and ending the immediate threat.
