Don't quite know if anyone else pays attention to the BS-12 forums. But the Baystation community (Specifically Zuhayr and a couple other delightful individuals) created this species, coded them completely (as far as I know), sprited a whole new set of clothing/icons specifically for this species and wrote a great lore-background for them.
The species to-which I am referring to is the Resomi (Roughly based on the Avali mod from starbound). I like to call them Fluffy space raptors.
The main draw to this race in my mind is their ACTUAL MECHANICAL DIFFERENCES FROM HUMANS. Listed below
-Due to their nature as Herd animals, they hallucinate if away from people for long amounts of time
-They're 4'5'' at tallest, can fit under flaps and can be picked up
-They have horrible visions, so they constantly have a welder-vision debuff
-They have amazing hearing, and so have thermal vision to simulate this (Thermal vision is lost if their hearing is damaged though)
-Due to their unique sprites, they have species-specific clothing!
-Due to being tiny, and...birds (hollow bones for gliding) they only have 50hp compared to a Human's 100hp
BS-12 lore-wise the Resomi are redonkulously hyper-advanced their society is in a state of post-scarcity and they have lots of ringworld-manufactories that make it so very few individuals in their society have to work. They use nanotechnology-injections to create (Lamely named) 'skill shots' that teach you things instantly, but as far as I know they're isolationist. They trade and all, but individuals have to be directly invited by a Resomi to enter their territory. Annnnd they're banned from Sec on Bay afaik, because 50hp is...just too fragile. Scopes seemed to like the idea of the species, and since several of you guys have complained about aliens species just being resprited humans. A species with actual mechanical differences would be welcomed!
