(U.C. 0079.12.31 - 0080.01.01) Just as Gihren Zabi proudly announces to his troops the decimation of the Federation fleet by the Solar Ray, the 603rd received its latest prototype weapon — the massive Big-Rang mobile armor. When the Federation launches a large-scale desperate attack on A Baoa Qu from two directions, the Kuspen Combat Battalion is assigned to defend the E field, and Oliver (to his shock) is ordered to pilot the Big-Rang. When the Jotunheim encounters a vanguard detachment of the Federation fleet, Oliver manages to inflict heavy casualty on the Federation forces with the help of Monique and Kuspen. Although the Big-Rang pushes back the first wave of attack, vengeful Federation soldiers eventually overwhelms and destroys the mobile armor, as well as killing Kuspen. As the retreating Jotunheim mourns the loss of their friends, a small group of survivor mobile suits approaches, among them an alive Oliver held by Monique's heavily damaged Zudah.
