S1·E24 Gigant

As new earthquakes begin to herald Industria's incoming destruction, Lepka, who has survived the crash of his flyer, and a troop of loyalists secretly channel some solar power underground to charge up the Giganto, a giant warplane left over from the last war. When the power leak is discovered and cut, Lepka's forces covertly seize the control room and continue to divert power to the plane. Noticing the takeover, Lana and Monsley escape aboard the Falco to inform the others. Conan and his friends have just finished raising the sunken passenger ship when Lana and Monsley warn them about Lepka, and they return to Industria; but having completed recharging, the Giganto takes off. Conan's group attempts to stop it, but ends up crashing through the plane's surface. After pushing the Falco back out to enable Monsley and Lana to return to Industria, Conan, Jimsy and Dyce infiltrate the Giganto.
