I have had this kicking around in my brain for awhile. Seems like a logical villain for Captain Spectre when the war breaks out on the western front. I guess there should be a Japanese version also, since they exchanged technologies at the end of the war.
Anyway I tried to keep the image and all of the German infantryman during World War 2, including the famous 'potato masher' in the boot, only on a large scale. I figure he should be about 12 ft tall, to make them scary on the battlefield and in the sky.
Yet another of the weird world war two weapons that are so fun to make up.
