The Garm Rodi is one of the many machines created through customization of the Rodi Frame, which was mass-produced during the middle period of the Calamity War, and is equipped with heavy armor. Making use of the frame's characteristic versatility, it achieves a fine balance between mobility and defensive performance. The Dawn Horizon Corps utilize this versatile unit as the organization operates in a wide variety of areas, and needs a machine that could adapt to various combat situations.

The Garm Rodi has an unique armored visor for the head camera, and the commander-use version has a different silver grey color scheme, an added blade antenna on the head and another shoulder shield. The Garm Rodi's weapons are the same for both the standard type and the commander type and its pilot can select from a wide variety based on preferences and combat situations. Including the commander type, Dawn Horizon Corps’ MS teams typically consisted of 6 machines.
