The RX-0 Unicorn Gundam 03 Phenex was a new machine secretly built under the direction of a E.F.S.F. official who disapproved of the Vist Foundation's involvement in the UC Project. Using a psycho-frame body delivered in advance, it was assembled independently by the Earth Federation Forces and reflects the data of Units 1 and 2. Rather than that of a Unicorn, the Phenex's motif is that of a phoenix, illustrated with a much more elaborate horn/V-fin and a golden body.

In December 3, U.C.0095, the Phenex was deployed with the RX-0 Unicorn Gundam 02 Banshee in a debris-filled shoal zone due to reports of a Neo Zeon MS performance test. It then encountered the Sleeves and engaged in a heated battle against the AMX-107R Rebawoo. After repelling the Rebawoo, a Psycho-Frame resonance with the Banshee and the Rebawoo caused the Phenex to become uncontrollable. The Phenex attacked the Banshee, damaging it and then transformed into its Destroy Mode before destroying the bridge of its mothership, the Irish-class ship Échalote with its Armed Armor DEs. It went missing afterwards and only reappeared a year and a half later in U.C.0097.
