Also known as: フルアーマーガンダム(MSV), ガンダムフルアーマータイプ
A Mobile Suit from Gundam MSV.
The FA-78-1 Full Armor Gundam is a variant of the RX-78-2 Gundam equipped with extra armor plates, missile launchers, a twin barreled beam rifle and even a huge shoulder mounted rocket launcher. It was developed into the Heavy Gundam.
Not to be mistaken for the FA-78 Full Armor Gundam from Gundam Thunderbolt - a vastly different machine.
