Rhoark was one of the royal guards in service to Queen Kalista of Euphorix. He also served under Alonzo Dulak during his brief reign as regent. Along with another guardsman named Presk, Rhoark was instrumental in saving Queen Kalista when her body had been compromised by a parasitic creature known as a Greeshagurt. Rhoark was also present during the "Crisis of the Shield" in which a distraught Primus attempted to permanently destroy Euphorix's planetary shield in order to reunite with his beloved Queen Kalista.

However, some elements of the character's Pre-Crisis history may have been altered or removed for Post-Crisis New Earth continuity, and should be considered apocryphal.
