"Dirk Eric Pitt is a renowned adventurer. Cussler describes him as tall, 6 ft 3 in (190.5 cm) with craggy looks, dark wavy hair, and possessing a rangy build. His most striking feature is his opaline green eyes, which can be both alluring or intimidating, as need be. Pitt has a commanding presence which, combined with a quick, sly wit, often infuriates those opposed to him. His comical banter with his sidekick Al Giordino during stressful situations leaves the reader with little doubt that both are confident of their abilities."
