Aired on November 26, 2002

Gravion defeats a Zeravire using the Gravity Crescent but disintegrates after reaching its critical point. Eiji argues with Luna while scientists analyze the machine's gravity-altering properties. Eiji enters the Gran Kaiser cockpit to learn Toga's role, but Zeravire emerge from a Gravion fragment inside the castle. Mizuki saves Toga from destruction. Sandman urges Eiji to fight alone, though he struggles with the mecha's power. After being knocked down, Toga orders Eiji to activate Elgo Mode. Despite severe pain, Eiji pilots the enhanced Gran Kaiser into space to destroy the remaining enemies. The machine returns to Earth seemingly lifeless after the battle concludes.
