Deep within each sperm cell is a fully formed, miniaturized individual called a homunculus. These microscopic "little men" simply need time to gestate until they grow large enough to be born. This is the basis of preformationism, which has risen to prominence in the 19th century. Using alchemical sciences, an individual is able to grow these humans without the use of a second parent, creating their own children from scratch. By discovering this secret to creating life, human beings can make God irrelevant and take his place as their own supreme beings.

The human male produces millions of sperm in a single day. I plan to use my own cells to create an army of homunculi, which I will then use to conquer the world. Due to this method, I have created millions of my own "children" who are subservient to my will. There have been a few hiccups, however.

These sexless humanoids have grown to be grotesque representations of humanity, being completely deformed in appearance. They contain exaggerated features, such as elongated arms, overly-large lipps, giant hands, etc. Being unfully formed humans, they also lack a large degree of organs that people normally have. this should make them far weaker than humans and unable to survive for a significant degree of time. Instead, they are stronger and more resilient than normal. However, their physical forms are biologically immortal, and possess a remarkably strong healing factor that makes them difficult to kill.

How can this be explained?
