Deformed and crippled, violent and just plain nasty. The hideous creature was grown by the Doctor from a single human tooth. It may be of diminutive size and a bit lacking in the arm department (they never developed properly, they're just a couple of little stumps), but it can bite and it can headbutt. The Homunculus shows cruelty towards all living things and posesses near human intelligence.
This was a very simple one. The hardest part was shaving off the Night Goblin's shield, head and spear. Then it just needed some greenstuffing and a Flagellant head. I like that head. It's a good head. And the paintjob was simple and quick.
Homunculi in sixteenth century alchemy refer to miniature humans created by alchemists, usually out of human semen. Paracelsus and others give in their writings descriptions of alchemical procedures for making the little buggers. 'Homunculus' is Latin for 'little man', and there's another word of the same meaning, only Greek: 'anthroparion'.
