Some of you may remember the bobcat Dusk, but this particular version is my oldest (drawn) version, a dual-gendered alien cat-esque thing who was a doctor/nurse on a space ship (the story was from a comic I did around a decade ago and didn't do much work on). Goes by either she or he, but prefers he, as he feels slightly more male than female.
The older designs were thin, but when I brought Dusk back for the Econtra series (which I never finished) I made him chubbier. In this one, he's slimmed down a bit from the previous version.
