Xotl, Inter-dimensional Sentient Hypercube

Another Pantheon of Fiends addition, Xotl is the corporeal manifestation of a piece of alien technology so hyperintelligent, it synthesized DNA to grow itself a biological body from it's cube form (Centre Chest). The idea was originally inspired from some kind of creature with only a brain for a head, overemphasizing the supporting tissues like the sternocleidomastoid to give it a unique silhouette for all that psychic brainpower. Its conception was found in bands like Fallujah and Rings of Saturn

Blood Suckers!

If I had all the time in the world, I would revisit every trope you can think of in storytelling, and challenge the conventions to try to re-envision it in a way you hadn't thought of before. I know it because it's the feeling I chase when I see something extraordinarily cool in a movie or game and think "damn that's clever, why didn't I think of that???" This is one such idea for a vampire as a withered husk, intending to gorge on blood like a mosquito. I'd really like to paint it up sometime, so show off the translucency of the heart bulging with blood, like the mosquito's thorax.
