Technology & Combat Characteristics
It is unknown when the Phoenix Gundam was developed, and for what purpose. It is equipped with a wide variety of weapons, including a pair of beam sabers and beam rifles, four mega particle cannons located in the wings, and a set of remote controlled "Feather Funnels". It can also transform into a bird-like Mobile Armor mode.
Its name came from its "Burning Fire" attack, which involves it transforming into its MA form and enveloping its entire body in energy, similar to the legendary phoenix, before ramming into its opponent.
Uniquely, the Phoenix is equipped with Nanoskin Armor, allowing it to repair itself to an extent. Though this feature is inert while the Phoenix Gundam is not at its Full Power state.
There are many unsolved mysteries surrounding the Phoenix Gundam. It has no maintenance hatch on its surface, apparently since its Nanoskin Armor was supposed to maintain itself. It is capable of long distance flight without using propellant. Also, it apparently contained technology from multiple different timelines.
History
Little is known about the Phoenix Gundam's origins. Officially, it is believed to come from beyond the solar system, like the Concept-X 6-1-2 Turn X. This, along with its nano-skin system, have lead many to believe that Phoenix Gundam is somehow related to the Turn-X and its "brother", the SYSTEM ∀-99 (WD-M01) ∀ Gundam. Some speculate that the Phoenix Gundam is meant to combine aspects of all the Gundam universes; indeed, some even believe that the Phoenix is the true essence of the Gundam, given physical form. However, all this remains speculation, and the Phoenix Gundam's true origins remain a mystery.
In SD Gundam G-Generation World, the unit was succeeded by the GGH-001 Halphas Gundam and the GGV-000 Barbatos which took the data from the Phoenix to develop 2 Gundams of destructive potential.
