In Ukrainian mythology, a werewolf person, for a certain time, takes the form of a wolf. The wolf was more often described as an ordinary wolf, sometimes oddities in appearance and behavior were indicating his human origin. Volkolak retains intelligence, but cannot speak.
There were beliefs about people who had a tendency to periodic werewolf from birth as a result of the behavior of their parents or appeared as a punishment for their own sins. Also among people there were rumors and tales that the Volkolaks were the scouts of the Cossack Sich. They had a great advantage in battle over humans, so they were recruited for wars.

I decided to adapt and portray it in my "style". Turned out pretty fluid and I really liked to draw him so maybe in the future there will be more :D
