I am sooooooo happy how he turned out! Caleb Faust is a demogorgon, set in an AU where his kind break free of the hivemind and are capable of assimilating into the human/furry world. He arrived in the human/furry world in 1994 as a 'demodog' and was a part of the initial batch of test subjects to attain 'personhood.' Studying things like mathematics, physics, chemistry, and psychology(online courses) eventually led him to become the primary official in charge of assimilating his kind into the new world. Below are stats, but he can very slowly change his body. Currently he has a German shepherd skin design but no fur.

Stats-
Height: 8' 2"/248cm(standing straight, top of head with closed petals)
Weight: 350 lbs./158kg (dense muscle)

You should check out the artist! She did such an awesome job, even coming up with a upside down design for his back! https://twitter.com/DemogorgonFluff
