Gravion

After Gravion unleashed its ultimate attack, the Zeravire threat appeared to be over-at least for a while. But when the enemy suddenly resurfaces, Earth Gult has no choice but to rely on its last line of defense, the super robot Gravion, once more. Meanwhile, the EFA is working on their own weapon to fight the Zeravire: the Grand Trooper. As the battle rages on, the people of Earth Gult and the EFA must not only protect their future but also face their pasts and uncover the secrets behind the Zeravire's origins.
