After Psimon's having been banished by Trigon to another dimension for his failure to destroy the Earth, the other members of the Five later attacked the Titans at their newly unveiled headquarters, Titans Tower, in "New Teen Titans" #7 (May 1981), using Silas Stone, the father of the superhero Teen Titan, Cyborg, and the Titans’ dimensional transmitter to return the apparently alive Psimon back to them. The Five were again defeated. Psimon later allied himself with the immortal dimensional traveler known as the Monitor during the seminal 1985 event known as "Crisis on Infinite Earths". Feeling betrayed, the rest of the Five turned on Psimon and apparently murdered him.
