#duspituop

They're both of a species called 'Duspituop", which primary characteristic is that their bones and horn(s) are actually 'organic' precious stone that have healing property. When they're in a humanoid form, they can also take their horn(s) down and morph them into various tools or weapons.

One big subspecies is the equine one or "unicorns", which Arty is, and that was until recently not even a subspecies but just the whole species (I got more ideas since). 

And Oqwuji is now of another subspecies, ressembling the Greater Kudu, hence the two big curly horns at his sides.

Also, Arty's stone is an emerald (certainly with a bit of quartz or something, I'm not sure yet), and Oqwuji is a tigereye.

Another thing about the Duspituops is that they mostly all (or maybe just all, I have yet to think it too) have gloves with a two length depending of if they're male or female: short for male (covers hands and wrists), long for female (goes up nearly all the arm). (Other species often use that fact to identify them as each or the other if they really want to know, cause the two gender often look similar)

Another good thing is that with their special characteristic, Duspituops are capable, little by little, of altering their own body by manipulating hormones and others. So the trans like them can mostly transition by themself! Not completely turn but come really close to the gender they feel they are. As a consequence, their gloves change length, not completely either but really close

Hence why they look at each other gloves. (Wow that was actually very long just to explain that ^^")
