Bates, Swan and Chiaramonte bring back the Galactic Golem in Action 502 (Dec. 79).
The story has Superman and Supergirl discover an alien infant, the Star-Child. It will grow to maturity in a day, and they have been asked to oversee that. Superman brings the rapidly aging child to the Fortress of Solitude. They need to teach it what it is to be human, as it will be an extremely powerful being when fully mature.
The Galactic Golem, last seen in the early 70s in the pages of Superman, is drawn back to Earth, and Superman heads out to battle it. Supergirl stays with the Star-Child.
They see the Golem defeat Superman, and the Parasite emerge from its body. Supergirl theorizes that the Parasite drew the Golem here, and merged with it to drain Superman.
Good guess, but totally wrong. It was all a ruse by Superman, to evoke emotions from the child. The only way he could figure out how to teach him emotions was to traumatize him. Fortunately, the Star-Child is fully grown by the end, and leaves for a less stressful life.
