Dr. Rick Spartan is a jungle explorer, who worked for a time as a biology teacher at Crystal Cove High School. His long experience with escaping traps has made him the hero (and somewhat of a role model) of Fred Jones, Jr..
Rick is a Caucasian male, with a short, blond buzzcut; with his lantern-jaw and muscular body, he looks like the typical man of action. He has tanned skin, suggesting he spends a lot of time out adventuring.
He neglects the safety and comfort of his wife in favor of jungle adventures, which is what led her to create the Headless Horror in the first place, and in the end, briefly leave him.
