These were drawn before I changed Raptor's usual hairstyle, so these sketches kept the original, longer hair for the androgyne form.

I haven't given Reaper (the newly named Fehrr inside of Raptor) much love recently, despite having plenty to vent and rage about. So I doodled it a bit in my new sketchbook.

Information on the Fehrr species is found here (body structure), here (owner-given info) and here (information from the Top Fehrrologist).
The species creator and owner is Felisrandomis

I have permission from Felisrandomis from when I first created Reaper to have it so that Raptor's daemon blood allows them to keep the Fehrr's nature at bay for a certain amount of time. Each time they fight Reaper off, it gets harder and harder to maintain control. Eventually Raptor is either forced to give in, or is taken unaware during a time of severe emotional stress. If Raptor gives in, they hole up inside their head and try to block out the emotions Reaper feeds on, and the pain and fear of its victims as it hunts and kills. Eventually Raptor regains their strength and uses their daemonic abilities to overpower Reaper's "personality" and regain control of the mutilated body they inhabit. From there, Raptor usually is forced to go into hiding for a few days in a safe and protected location in order to heal the immense damage to their body caused by the Fehrr transformation.

Another small detail is that I've made Reaper's eyes the default bright red because I haven't quite figured out a way to alter Raptor's natural eye colors into Fehrr colors that actually looks good. Fehrr turn the host's main fur/body color black and alter their colors, including eye colors, but I don't quite know how to make Raptor's eyes look decent.
