I don't care for Sten really, Asharok just has a certain quality to him. It's not even because he's big, muscular or horny. It's simply because I find him to be oddly ADORABLE. Which you may find odd. However, Merill mentioned how they scratch their heads with those horns in the way. So she mentioned them using trees. = Adorable
Then of course I saw a chibi Asharok, it was adorable.
Oh, and he's excessively angry and wise. The wisdom is sexy and so is the ambition. The angry just means great sex of course.
The next thing being his voice, it's pretty hot.
Oh, and back on the cuteness factor. His running attack before you kill him? When he runs into walls? #Adorbz
