UNPOPULAR OPINION/HOPE CRUSHING TIME!
*ollies out of fandom*
I can see why you'd say that, but personally, I actually find skulls to be rather cute. They're one of my favorite things to draw, as evidenced by my art thread, and her design, when you look past the creepy Cal eyes and initial shock, is actually quite fetching! ;D
But then, I think the stark contrast between her looks and her personality is charming as well. Like Ghouls in the Fallout canon, there are some that I find to be cute who have absolutely no pity for themselves whatsoever, like Willow. I think any dangerous looking creature, when given a polite and kind demeanor gains some level of cuteness. I will not lie, UU's appearance made me JUMP when I saw it, as I admitted a couple posts ago, but that was more the initial shock. I had absolutely NO idea what to expect and her eyes. HER EYES ARE CAL EYES
. Say we'd been led to believe Tavros was a human character for a long time, with hints he may be something more foreign. It would be unsettling if all of a sudden OH GOD HE'S A GRAY ALIEN WITH GIANT HORNS FUCK.
