The Alligator is a minor nuisance in the animated movie, Highlander: The Search for Vengeance. Though, the Alligator does not appear directly in Heroes vs. Villains War, his archive footage is mainly used in the final events of the war.
Heroes Vs Villains War
The decapitation scene of the alligator is used for the death of Dil, a villain from another movie. He is chopped by Hercules, as the alligator attempted to devour, unsuccessfully, Snow White and Dahlia. This is the only depiction of the Alligator, as it does not reappear again.
