The 4th season of the Full Metal Panic! TV anime, often shortened to FMP! IV. It is the only season animated by XEBEC, and adapts volumes 7-9 of the original light novels. Unlike previous seasons, the mecha in IV are rendered in 3D, while human characters and environments are in traditional 2D.
The ARX-8 Laevatein makes it's TV debut in this series, although the unit and the season's events both made their Super Robot Wars debuts before the series aired, in Z3.
