I tried to recreate the red 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, the red work-type Zaku (I arbitrarily named them A and B). The base is the GQ Char's Zaku.

Like the other civilian Zakus featured on the mecha page, the lower legs have been slimmed down and guard pipes have been added. The guard pipes are made from Tamiya soft plastic rods.

The left hand, taken from another GQ Zaku, has been modified to look like an open right hand.

Because it's a civilian Zaku (?), the inside of the thrusters is white.
