RX-0 Unicorn Gundam 03 Phenex is a golden, psycho-frame mobile suit from Kidou Senshi Gundam, created as a variant of the Unicorn Gundam series. Unlike a human character, it is a machine and does not have a personal given name and family name in the usual sense, so the designation is used as its full name. Phenex plays a mysterious and symbolic role in the series and related works, representing the dangers and transcendence of Newtype technology, while appearing as an elusive, almost ghost-like presence on the battlefield.
