The Full Armor Mode was an enhancement plan devised by Takuya Irei while aboard the Nahel Argama and is based on Takuya's extensive knowledge of mobile suits. After Banagher's Newtype potential manifests itself, the psycoframe changes color to a vibrant green. Unlike other mobile suits with the Full Armor designation, the FA Unicorn does not consist of any additional armor for the MS frame itself (except extra shields). However it does introduce a large array of weapons, which are added to the legs, backpack and forearms.
