The osunax
This thing is a race I've had in mind for quite a while, problem is, because of their nature it's hard to draw what one looks like. The basic idea is that Osunax are devoid of an actual body, but they exist on the physical plane.
But rather than just being a walking ghost of sorts the Osunax gained the ability, or rather realized it, I suppose, to steal what they desired from things around them. The picture above is essentially a pure Osunax. and by that I mean they've yet to start stealing parts off other beings. But don't be mistaken, it's not like they hack up their victims and sew the parts onto themselves, it's a rather painless process (well.. that depends on which part they take) that involves grasping the desired appendage or trait and absorbing it right off the victim in exchange for the corresponding part of themselves.
Now, you see, this is problematic because a human cannot sustain an Osunax part, so while gathering their first few body parts, a fresh Osunax may very well have to kill a person or two to get a complete body. From there, instead of trading, or rather stealing, a part off a person they take said trait or part and exchange it with one they're already using.
But that's just how they work. To summarize - the Osunax can take any trait they want off a person as long as they make physical contact with it, but the desired part must be exchanged. A fresh Osunax can be quite messy because they start with nothing to trade and end up just taking (which is kind of taboo among their race)
Now, you see why I couldn't just draw them normally, they'd just look like normal people
But, onto the main points of this new species!
How they were created.. well.. I'm still working on that.
So, anywaysm whenever they came into being, it was a long time ago, but roughly around the time of the first physcial beings. the Osunax are an ageless species because, among everything else, they can take age too. But there is a point where a very old (timewise, not agewise) Osunax must give up their physical form and take a short refreshing period, usually disappearing for a month or two all together.
However, an Osunax may take on a human form, but the most distinguishing feature that sets them apart is their eyes. Regardless of what form they take, or in some cases create, an Osunax will always retail their monotone pupilless eyes. Usually a blueish tone, but in certain cases they can be other colors.
Aside from just that, but because of their large focus of body parts and appearance, they're all quite vain but also, they've developed quite an eye for quality body parts and can usually tell the state of an organ by examining the person. Because of this, they are also prone to collecting pets, usually of varying species, mostly for spare parts.
Also, due to their huge lifespans, their memories have become selective. It's a matter of remembering what they'd like to remember as opposed to storing everything that comes at them like humans.
