Sky Riders from Hell Episode 25

A spaceship from Earth is suddenly attacked by meteorites, and the Science Ninja Team hurries to the bottom of the sea, to the spot where the meteorites fell. But there, mysterious robots that arrived a bit earlier, are already collecting the meteorites. Is it Galactor...?? Joe follows the robots and corners them, but they are not Galactor. On the contrary, they greet him as "brother". They are cyborgs as well who have been made by Dr. Raphael. A cyborg who introduces himself as Ulf leads him to their colony. There he meets Ulf's comrades, who are equally friendly, as well as Dr. Raphael. Then he learns that they want to invite him to a strength experiment. Before Joe's eyes, many cyborgs die when they are tested under extremely hard conditions. Then Joe is called by Ken and has to return to G-Town. Elsewhere, Galactor has noticed the existence of Ulf and the others. Using the meteorite's guidance system, they let meteorites fall onto the colony and destroy it. Joe sees this on the monitors of G-Town and hurries to the colony, meeting a dying Ulf. Then he goes to Dr. Raphael. The strength experiments of Ulf and the others were intended to make Joe's body stronger. Joe tells Dr. Raphael "I did it so far, but I don't want to become a perfect cyborg! I want to live as a human being!". Dr. Raphael answers: "Then listen, Joe! Your body has to absorb the result of their blood and sweat, you have to become stronger because of them!" Since his cyborg comrades have become victims, Joe honours their will and submits himself to an operation which transforms and strengthens him. Joe can now resist very high temperatures and stand high pressure. He can even use the pressure and heat as his own energy. Thus strengthened, Joe saves Ken from a Galactor base where Ken got shot down, trying to destroy it with his G-1.
