Power Girl
Vartox returns in the "Power Girl" ongoing series. All the women of Valeron have recently been made sterile by a "contraceptive bomb", prompting Vartox to search for the best female specimen in the universe, so that they may mate and repopulate Valeron. Selecting Power Girl as the prime candidate, Vartox comes to Earth, staging a fight with an Ix Negaspike, a creature that is indestructible, in an attempt to woo her. However, Power Girl accidentally breaks Vartox's containment device, making it impossible to send the Negaspike back. She attempts to stop the Negaspike by freezing and shattering it, only for the pieces to reform into a swarm of Negaspikes. Realizing that the Negaspike's intelligence is split between its parts, Power Girl and Vartox freeze and shatter all the individual Negaspikes, reducing their copies to "indestructible space-cows", before freezing them again and throwing them into space. Vartox then invites Power Girl to dinner, and she accepts. After Vartox describes his people's predicament, he has Power Girl enter a "fertility chamber", which combines their life-forces to send out a "pregno-ray" to Valeron, making all the females and males pregnant. His mission complete, Vartox departs.
