There's a new Gravion called sol Gravion. Zieg recognizes its power source as a device that decimated an alien race. It turns out the main pilot of the Sol Gravion is Ena. Ena tells us she's a clone of the original that died, but has all the memories of the original. The Zerivire apparently leave (yet another unexplained plot hole.) The Gravion team takes the Sol Gravion for a test spin. Sandman tells us that the Sol Gravion has the power to destroy the world - or create a new one. Eiji and Toga make up for their fight. Sandman frees Eiji, saying he has no obligations to Sandman anymore.
Later Sandman talks to the President. The president pleads for continued support of Gravion. Then Sandman tells Raven that the true power behind Gravion Sol is the friendship and love that the team has for each other.
Hugi then tells via a hologram that he will destroy earth in 48 hours. Some of Hugi's holograms attack Gravion. Then St. Germain castle takes off, shocking a lot of the maids on board. They form Sol Gravion, preparing for the final battle...
ゼラバイア本星ゴーマから、大量に転送されてくるゼラバイアに大苦戦するゴッドグラヴィオン。もはや、各グラントルーパーも力つきようとしていた。そこへ太陽を背に新たな機体、ソルグラヴィオンが現れる。
Sandmann hat Sol Gravion auf die Erde herabgerufen! Die Gran Knights können ihren Augen kaum trauen, als sie sehen, wer ihn steuert. Hugi, erzürnt wegen Sol Gravions Erscheinen, setzt Earthgartz ein Ultimatum.
