Kagaku Ninja-tai Gatchaman II EP43 - Invaders From Mars

While investigating Mars, an Earth satellite is blown up, and a second space base on Solkila Island is destroyed as well. But the culprit is not Gel Sadra. She faces the fact the Governor X praised the destruction of the first base as a hint. She assures that she can do this as well and goes out to do so. When a third space base is about to be annihilated, the Science Ninja Team goes out to help. But the New God Phoenix has to make an emergency landing because it's attacked by a mysterious UFO. The base is destroyed and Gel Sadra arrives too late to do it herself. The Science Ninja Team goes to protect the fourth space base which is working on launching an unmanned exploration probe to Mars. Just after the launch, the UFO attacks again. The probe is destroyed. What is there on Mars?! Without pausing, the UFO goes on to attack the fourth space base. The G-Mechas fight back and through their intervention, the UFO disappears somewhere. The owner of the UFO is Marstora.
