Rattlesnake Jake is a large western diamondback rattlesnake. He wears a black leather cowboy hat with a cross-laced leather band, shed skin resembling a vest, and a Gatling gun in place of his missing rattle on the tip of his tail. He is also shown to have small black scales on his upper lip that greatly resembles a mustache as well as other darker areas. In addition to his massive, venomous fangs, he also has numerous sharp and cruel fangs across his jaw that compliment his sinister demeanor.
