The RX-0 Unicorn Gundam 03 Phenex[1] (aka Phenex) is a mobile suit that appeared in Mobile Suit Gundam UC: One of Seventy Two. It also appears in the manga Mobile Suit Gundam U.C. 0096: Last Sun and the Mobile Suit Gundam Unicorn novel. It makes its animated debut in the movie Mobile Suit Gundam Narrative, which succeeds the events of the Mobile Suit Gundam Unicorn OVA. It is piloted by Rita Bernal.

Technology & Combat Characteristics

The RX-0 Unicorn Gundam 03 Phenex was a new machine that was secretly built under the direction of a EFSF official who disapproved of the Vist Foundation's involvement in the UC Project. Using a psychoframe 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.


  • 60mm Vulcan Gun
A basic armament found on many Federation mobile suits. While essentially ineffectual against mobile suit armor, they are useful in intercepting incoming missiles/rockets, destroying mobile suit sensors, and engaging lightly-armored vehicles.
  • Armed Armor DE
The normal I-field equipped shield used by the Unicorn Gundam with additional parts containing a propulsion system and a mega cannon, it is similar to Shield Boosters that were used in the Gryps Conflict. The Phenex is equipped with two such shields and they are mounted on the back like a pair of wings, demonstrating explosive accelerations. DE stands for Defense Extension. The version featured in Mobile Suit Gundam Narrative also has tail-like stabilizers on the Armed Armor DE for attitude control and can be used as remote-controlled weaponry.
  • Beam Saber
The standard close range armament for most Federation mobile suits. The Phenex is equipped with four beam sabers, two on the forearms and two in the backpack. In Unicorn mode, the MS only has access to the two forearms mounted beam sabers. In Destroy Mode, the other two beam sabers flip out from the backpack, allowing access to all four sabers.
  • Beam Tonfa
The forearm-mounted beam sabers can be flipped over and used directly. In this form, the weapon is known as beam tonfa.
  • Beam Magnum
A highly customized beam rifle designed with an energy condenser, a single shot from the beam magnum is equal in power to 4 normal beam rifle shots but it uses up an entire E-pac. Each of the beam magnum's magazine is loaded with 5 E-pacs, allowing a total of five shots before a new magazine is needed. The Phenex can carry two spare magazines on its rear skirt armor.

Special Equipment & Features

The Newtype Destroyer (or NT-D) System is an anti-Newtype system developed by the Earth Federation and used on the RX-0 series. The system works by using the Psycoframe built within its body to seek out Newtype brainwaves. Should one be found, the NT-D System activates and turns the Unicorn Gundam (The Unicorn Gundam, the Banshee, and the Phenex) from its usual "Unicorn mode" into its "Destroy mode", improving its stats overall and allowing it to take control of Newtype weaponry used by others and turn them against them. However, the system has a number of flaws to it, among them being having a five minute time usage so it wouldn't kill its pilot and the fact that it doesn't discriminate against real Newtypes and Cyber-Newtypes. Its most ironic flaw is that, because of the massive stress to gives its pilots, a Newtype is the best pilot for the unit. Perhaps the greatest flaw in a weapon system is the automatic response. The NT-D activates automatically when a Newtype opponent is detected. Once active, it will attack, even against the pilot's wishes. Thankfully, those with strong wills can overpower the system and determine when it can activate.


The Phenex is fielded in December 3, U.C.0095. deployed with the RX-0 Unicorn Gundam 02 Banshee in a shoal zone filled with debris 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 Psycoframe resonance with the Banshee and the Rebawoo causes the Phenex to become uncontrollable. The Phenex attacked the Banshee, damaging it, and destroyed the bridge of the mothership Shallot. It went missing afterwards, and would not appear again until two years later in U.C.0097.

Following its return, the Earth Federation Forces cruiser Damascus was deployed as part of the "Phoenix Hunt" taskforce at the request of the Intelligence Bureau, with the intention of capturing the Phenex. The intervention of Jona Basta and the Narrative Gundam allows the operation to almost succeed in capturing the Phenex, however Jona allows it to escape. The Phenex later assists Jona in the battle against Zoltan Akkanen and the NZ-999 II Neo Zeong. It leaves afterwards, heading towards the center of the galaxy.[2]




Notes & Trivia

  • The Unicorn Gundam 03 gets its namesake from Phenex, the 37th demon of the Ars Goetia. Phenex is described as a Great Marquis of Hell who takes the form of a phoenix, commands twenty legions of demons, and teaches science and poetry.
  • In Gundam Breaker 3, the Phenex can detach its Armed Armor DEs to function as remote controlled weaponry in a manner identical to the RX-0 Full Armor Unicorn Gundam. This ability is carried over into the Mobile Suit Gundam Narrative film.
