This wolf character came from the "The real gosthbusters" episode "Who're You Calling Two-Dimensional?".

Winchester Wolf was one of the creations of Walt Fleischman, a famous aniamtor in the gosthbusters's world (as well as a parody of Walt Disney). Walt desired so much that his characters became real that at some point, for unexplained reason, his mind somehow created a parallel universe where all his cartoon characters existed as real living beings.
Unfortunately for him among his creations there was Winchester Wolf: Winchester was evil and very soon he became too powerful, so powerful that he was able to kidnap his own creator that was tortured by the cruel wolf for many years (altough being in the cartoon world he never aged) through his own slapstick cartoon comics. In the end Walt was saved by the gosthbusters and his other creation and Winchester's nemesis, Doopey Dog.
In the cartoon world Winchester proved to be a powerful entity: he demonstrated powers like omniscience of everything happened in his dimension, ability to warp reality and size growing abilities.

In this pic I wanted to show him also not just growing in size but also gaining muscle mass: I wanted to try to stay also on a cartoonish drawing style.
I hope you will enjoy!
