MS-06F Zaku II (MS-06F ザクII), commonly known as Zaku, has an early claim to fame as being the very first Mobile Suit to display its abilities to the audience within the Gundam universe. Its mechanic roots are born from the desire of enhancing the powers and maneuverability of a tank, thus leading to a weapon with a human-like figure and two legs. Built from plans originally stolen from the Earth Federation early within the One Year War, it became a common weapon of mass destruction for the Zeon forces. As the name suggests, it's an improved version of the first walking mass-produced Mobile Suit, the Zaku I.
