This robot paper model is the Wildgoat, a wanzer model that appeared in Front Mission First, Front Mission 4, Front Mission Online and Front Mission Evolved, the papercraft created by animaniac. In its first appearance, it had a tread as its default leg part, but it then become a two-legged wanzer model in Front Mission 4 and Online. It is produced by the Leonora Enterprise of O.C.U. Australia.
Wildgoat and its variants tend to have above-average armour and output, but rather poor mobility and evasion, indicating that it is best suited for providing long-range support fire. In most of its appearances, Wildgoat was seen equipped with shoulder weapons. It was seen being used by the U.S.N. Army and Spirit of Huffman in Front Mission First. [Source: wikia]
