What if you would have a special “profession”, kind of a field medic… but there would be a catch. He would have a good side and a bad one.
The good one… would heal your soldiers if they are wounded, just like you expect him to do.
The bad one… well. Sometimes, his darker ego would gain the upper hand. He might be indicating that he will change his behavior and you might be able to prevent him to do so (small hits on the head?). However, if you do not, he still will turn towards your injured and weak soldiers, but maybe not focus too much on healing… “Oh, what a beautiful head you have!”. The result would be, that Dr. Frank Stein adds another body part to his collection.
As an alternative, he might not be a field medic, but more of an undertaker and simply collect body parts from fallen soldiers.
One or the other way, the result would be a collection of parts. In the sense of the actual recycling movement, well… a small workshop somewhere, maybe in a tower. The lightning strikes. A table located in the center of the room. The flash moves along some wires and hits the flesh. The rest is history…
Kind of interesting?
