Prime were acting very aggressively and attacked the Knight and Cromwell. It was revealed that Prime, Lament, and Topaz were infected by the Progeny virus and fought his counterparts from 50 years in the future that came to cure them. The Progeny virus would have infected all the Ultras in Earth. After they cured the virus and took Foxfire with them, the Ultraforce from the future erased the memory of this event from their counterparts of the past. Searching in the base about what happened, the Black Knight and Topaz released Specimen 13, one of several beings being kept in the secret basement and who was also Cromwell's brother. The specimen overpowered the heroes but was convinced by his brother to return to his chamber. After this, the Ultraforce joined the New Exiles, who were fighting an alien robot called Maxis.

When Ghoul arrived at the scene, he was accepted back into the team as well. Back at their base, the Ultraforce met Hardcase, but did not recognize him. Hardcase explained to them he was not erased by the Black September, but was shunted instead into a limbo, where he created the creature Demonseed as a companion in the loneliness. However, Demonseed rebelled against his creator and escaped to the past via a portal, where he destroyed innumerable alien civilizations. Demonseed finally appeared and fought the Ultraforce, overpowering them, Ripfire was killed in the last attacks of the creature, but Hardcase sacrificed himself to send Demonseed back to the limbo, where he fought it for all
