Biology
Aminopius were Humanoids and covered their faces with blue cloths. Through these cloths it is easy to identify that they had large mouths. (Non-canon story: Tonight's the Night)

Technology
Aminopius used robotic limbs as weapons, whilst they also had certain machines that could scan victims in order to see the value of their body parts, which could also double-up as a dissintegrator. They had built factories that processed victims into food. (Non-canon story: Tonight's the Night)
