This is a custom made version of the very first gundam built Wing Zero (as noted by the name "Wing Zero Custom"). Wing zero custom is the most powerful gundam ever built, but includes a very dangerous system called the "Zero system". This feeds tactical data and combal simulations into the pilots mind. Only a few pilots are able to handle this system, for example Treize Khushrenada with Epyon and Heero Yuy with Wing Zero & Wing Zero custom. This model of Wing Zero does not include "Bird Mode", which previously allowed the suit to take flight like a plane, but now is updated with feather-like wings. This enables the suit to survive re-entry into the atmosphere of the Earth and to also fly around the world. As in Wing Zero the primary weapon is the twin buster rifle.
