Death by Irony: All seven of Father's creations are defeated in ways that reflect each of their respective deadly sins they represent.

Dark Is Evil: Often decked out in black, lurk around in shadows, and are Eerie Pale Skinned Brunettes.

Born as an Adult: More or less, from what we see from the 2nd Greed's creation, Homunculi have sentience, intelligence and awareness of their powers once made, and with the exception of the human-based Wrath, they don't age or have childhoods.

When a Homunculus shows up, expect the fight to be a brutal one.

Badass Family: An evil family nonetheless, consisting of superhuman artificial humanoids with varying powers and their Physical God of a father.

Father himself was the very first artificial human.

Artificial Human: All of them except Wrath were created by Father in order to create pawns and means for Father to achieve perfection.
