Can Fala rise the occasion and form the head of GoLion without Kogane?

A mysterious young man known as Saint rescues Princess Fala after her Lion crashes. Back at the Castle Gradam, Raible is convinced that Saint is indeed his long lost son who he had sent away years ago during an attack to the Planet Altea. But Saint is actually a resurrected agent of Galra and when he is left at the controls of Castle Gradam he keeps GoLion busy giving Sincline time to transport a powerful new weapon to Altea…

Raible realizes that Saint is in fact an agent of Galra and Princess Fala’s former nanny Hys is shot and killed by Saint! Raible gains control and orders a recon squad to locate the Lions as the GoLion team regroups and plans to destroy the giant gun before it can be fired again.

Thanks to the GoLion team, Altea now has control of Sincline’s ultimate weapon and plan to use it to break through Planet Galra’s force field and take down Emperor Daibazaal once and for all.
