The Missing and the Lost
An extra-terrestrial race known for their mastery of bioengineering. Occasionally they establish outposts on Earth to harvest rare metals and human organs for use in their strange technologies. The Migou on Pluto (Yuggoth) are just a branch of a mighty empire that spans galaxies.
The Migou are not insects. The conception of an emotionless, uniform hive-mind ruling the buzzing masses is a fiction, dreamed up by writers of such popular adventure serials as “Carter’s Crusaders” or cartoons like “God Engine Abaddon”. But the Migou are not a race of individuals like Humans, they are neither, yet both at once.
There are only around 300 distinct personalities shared amongst the fungal invaders, and these personality “strains” come with their own quirks & habits, favored occupations, likes & dislikes, and have pre-set notions concerning other strains. Some get along naturally with particular strains, utterly despise others. There are strains that exist that cannot stand others from their own strain. It is not uncommon to see the same few personalities at the top of command structures in entirely separate legions.
Resistant to bullets: the Mi-go do not have specialized organs the way that terrestrial organisms do, but have a physiology more similar to fungi
Memory control: the Mi-go have the ability to shape, create, and erase human memories if they can establish a physical connection
Surgical modifications: it is common for the Mi-go to enhance their bodies with a variety of tools and weapons, from retractable scalpels to arc casters
