Ph'yzzon was a Tamaranean general and the second husband of Princess Koriand'r (Starfire). He was introduced to the Titans when an evil version of Raven, one of Starfire's former teammates, attacked Tamaran with the intent of killing Starfire, who was unknowingly housing the remnants of Raven's soul. Ph'yzzon helped the Titans fight Raven and in the process revealed his ability to create duplicates of himself called "binaries," a power that he gained through experimentation by the Psions. However, the Tamaranean fleet was defeated and the planet Tamaran destroyed. Despite calls for evacuation, many Tamaraneans were killed, including Starfire's parents Myand'r and Luand'r.
The Titans managed to restore Raven's soul, and Ph'yzzon and Starfire led the remaining Tamaraneans to settle on another planet which they called New Tamaran. Ph'yzzon then revealed to the Titans that he and Starfire had married three months prior, and Raven implied that Starfire was pregnant with their child, though she was apparently mistaken as this was never referenced again. Starfire later stated that her and Ph'yzzon's relationship was "more of politics than passion."
Some time later, Starfire came into conflict with her sister, Queen Komand'r (Blackfire), when an alien named Dusk attempted to warn them of New Tamaran's impending destruction by the Sun-Eater. Starfire believed Dusk while Komand'r did not, resulting in Komand'r banishing her sister from New Tamaran. Ph'yzzon remained on the planet and led Tamaran's military forces, but was killed along with many of the remaining Tamaraneans when the planet was destroyed by the Sun-Eater as Dusk had predicted.
