Winston and Egon when escaping, ask Leda where the others of the town were. Leda then leads them to the jail all the citizens were imprisoned. The Leader asks if it's a full moon, to which Winston a bit confused answers "Yes", and then "Why?". The leader and his fellow citizens confront Gregor and the vampires. It is then realized by Ray that Lupus means "wolf" meaning the town is of wolves. The leader and all the citizens turn into werewolves and begin to battle the vampires. The Ghostbusters leave all the werewolves and vampires (including the leader) behind and block off the town with water.
- The Leader was voiced by Frank Welker.
