I tried to recreate the blue work-type Zaku that appears in a still image at the beginning of the Zeek Axe anime.

In the opening of the first episode of the TV version of Zeek Axe, several civilian Zakus appear loitering around Sodom, and this is one of them, a blue (or green?) work-type Zaku (I arbitrarily named it A and B). The base is a military police Zaku.

Here it is alongside the red one that appears in the same scene.

Since it's a civilian Zaku without an installer device, the mono-eye is green. Painted with water-based hobby color fluorescent green.

The left shoulder armor has the spikes omitted and a guard pipe made from Tamiya soft plastic rods has been attached.
