Winchester Wolf is a large, slender, muscular brown wolf with a white muzzle, a pink nose, orange eyes, a purple cape with a red interior, black pants, and purple gloves.
Walt Fleischman soon added new characters to his cartoon world. Among them was Winchester Wolf. Wolf was evil and became too powerful to control. Winchester Wolf held Fleischman prisoner and had him tortured in a manner similar to slapstick comedy for many decades primarily to pay back Walt for torturing his own creations. He was eventually defeated by the combined efforts of Dopey Dog, the Ghostbusters, and all of Walt Fleischman's cartoon creations.
- Winchester Wolf is possibly a reference to the Disney villain, Pete.
- He was voiced by Frank Welker.
