The Return of Joe?!

Overview

In the country Amelia, between the cities New Jork and Scratton, there's the Dera Desert. Below that desert, Galactor is building a scecret base which is supposed to become a very important military strong point. But because they have rushed its completion, a huge explosions occurs and triggers a 9.2 magnitude earthquake in the area. The two cities get into a very critical situation. In order to find out what is happening, the team launches a sensor-equipped rocket drill into the Earth. The data is sent to the New God Phoenix and analyzed by Nambu. However, after the launch, the team is ambushed by Galactor and, yet again, the mysterious person saves them. The only way to save the cities is to dive under the desert in the Condor Attacker, since it can take the pressure. Through the explosive power of the Fire Targetter, which is equipped with the ultra powerful Tektay explosive, the mantle convection can be calmed down. However, there's no G-2 to pilot the attacker. Just at this moment, Condor Joe finally appears alive before the Science Ninja Team. Then Ken and the others face the mecha which has appeared, while Joe accomplishes his task perfectly.
