He's a bit of a... weird mix of inspirations...

At first, I got inspired to make a husky because of visual novel characters Walter(After Class) and Spencer(Extracurricular Activities), which also happened to be huskies.

Then, I built on him more by borrowing from a couple of canines in some mythologies like Fenrir, Garmr and Cerberus, anime characters/concepts such as Joseph Joestar for his goofy personality, Yami Sukehiro and Naruto's shadow manipulation techniques for the void powers. In addition to this, I added in a bit of smiledog in him as well to expand on his enigmatic nature.
