The RX-0 Unicorn Gundam 03 Phenex is a mobile suit that appeared in Mobile Suit Gundam UC: One of Seventy Two, a short animation feature at Gundam Front Tokyo's "DOME-G" on August 3, 2013. It is based off a short story written by Gundam Unicorn's author, Fukui Harutoshi. To celebrate this short animated feature, Bandai Hobby produced a limited Gundam Front Tokyo HG model kit of this design.

Technology & Combat Characteristics

The RX-0 Unicorn Gundam 03 Phenex was a new machine that was secretly built under the direction of a certain EFSF official who disapproved of the Vist Foundation's involvement in the UC Project. Using a test full-psychoframe body which was in an incomplete state before delivery, it was assembled independently by the Earth Federation Forces and reflects the construction 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.
  • Beam Saber
The standard close range armament for most Federation mobile suits. The Phenex is equipped with a total of four beam sabers, two on the forearms and two in the backpack. In Unicorn mode, the MS only has access to the two forearm mounted beam sabers. In Destroy Mode, the other two beam sabers flip out from the backpack, allowing the MS access to all four sabers.
  • Beam Tonfa
The forearm mounted beam sabers can flip over and be used directly, in this form, they are known as beam tonfa. This mechanism is a modified version of the Sinanju Stein's.
  • Beam Magnum
A highly customized beam rifle designed with an energy condenser, mirroring the output of large mega-particle cannons. Normally, it functions like an ordinary beam rifle, but utilizes a special E-cap magazine mechanism to produce mega-particle cannon yield at the expense of an entire E-cap battery.

Special Equipment & Features


The Phenex is fielded in December 3, 0095 U.C. where it is 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 causes the Phenex to become uncontrollable. The Phenex attacked the Banshee, damaging it, and destroyed the bridge of the mother ship.

Notes & Trivia

  • The Unicorn Gundam 03 gets its designation from Phenex, the thirty-seventh demon (out of seventy-two) of the Ars Goetia. Phenex is described as a Great Marquis of Hell who takes the form of a phoenix (his namesake), commands twenty legions of demons, teaches wonderful sciences, is an excellent poet and hopes to return to Heaven after 1,200 years.
