I've been asked this before, cause people question how he's really a wolf demon
He's a huge ass mutt of things
Theres inspiration from:
Wolves
Demons
Jacobs Sheep
Boar
Bats
Saber tooth cats
Shukaku (hahaha, his original design came from my own version of Shukaku actually)
And mostly, without a doubt... and I've never liked to show people cause it makes him seem less unique...
