Phenex is the 37th of the 72 Demon Gods, holding the title of Marquis. It is said to converse in rhymes.
Phenex was one of the pillars that administrated the Arsenal.
Final Singularity: Solomon
Phenex was one of the pillars that administrated the Arsenal. After the defeat of Goetia, it was one of the four Demon Gods that escaped from the Time Temple.
Subspecies Singularity II: Agartha
After escaping the Time Temple, Phenex summoned Scheherazade, and sympathized with her fear of death. Together they conspired to reduce the world's Mystery to render the Servant Summoning System and other related existences obsolete. Phenex empowered Scheherazade's Noble Phantasm, Alf Layla wa-Layla, to make her stories real. He then ordered her to use her newly enhanced Noble Phantasm to create the Agartha Singularity. After this was done, he ordered her to summon Heroic Spirits into the Singularity, and to incite conflict amongst them. The impending conflict between the Servants would eventually form a vortex of magical energy, and Agartha’s enclosed nature would trap the souls of the vanquished Servants. Agartha would then exploit the energy generated by the souls as they try to return to the Throne. Eventually the energy would turn the Singularity’s fictional nature into reality. Once this is achieved, it would be used to destroy a real city to damage human understanding to destroy the concept of Mystery, rendering all existences related to it obsolete. Phenex believed doing this would eventually result in humanity’s destruction.
Throughout the events of the Singularity, Phenex keeps himself hidden inside Scheherazade’s body. Because of his unique ability as the Demon God of death and rebirth, Chaldea could not detect him. Scheherazade eventually releases him from her body after Agartha turned into Laputa. Ritsuka’s party fight and kill him, though at the cost of Fergus mac Róich being severely injured. Even with his death and Scheherazade near death, Laputa continues to exist. Eventually Phenex resurrects himself through the corpse of a Resistance member. He declares Laputa will continue its descent even if he’s killed and reveals his true ambition regarding it. He then fights the group to ensure his promise to Scheherazade will be fulfilled, nearly killing them when Wu Zetian ambushes him. She had been biding her time after her supposed death until Phenex separated from Scheherazade. She then tortures him with her Noble Phantasm, Manual of Accusation, but he severely wounds her in retaliation. She pleads with the group to kill Phenex while he’s in a state of life and death. However, to the others’ surprise, Fergus walks into her Noble Phantasm to use its concept of mixing life and death together to essentially resummon himself through the use of Columbus’s Tamatebako. He soon achieves his goal when his short sword turns into Caladbolg and unleashes Caledfwlch Caladbolg on both Phenex and Laputa. With Phenex being constantly damaged by both Noble Phantasms, the group fight him once more. Afterwards, Phenex extends tiny tentacles from himself, and implores Scheherazade to give him her magical energy. She however refuses to die by him, and Fergus finishes him off.
Aside from the standard abilities displayed by the Demon Pillars, Phenex is a Demon God governing death and rebirth, seen in a similar fashion to the Phoenix. As such, it is capable of reviving by itself after being killed. Phenex is also capable of assuming a humanoid form.
Phenex was capable of bolstering Scheherazade's Noble Phantasm to the level required to create the Agartha singularity, an encroachment of fiction onto reality.
