Hank Ryan is a tough military soldier who lives in an army base in Dimmsdale. The markings on his uniform and his manner of speech suggest that he is in the United States Marine Corps.
Hank wears a green camouflage military cap and uniform. He has huge arms and a massive chin. He resembles a human version of Jorgen but his arms are much bigger in proportion to his body.
Hank has a son named Nathan who is also in the military, and Sanjay is his step son through marriage to his mother, Amisha Patel, as Hank lost his former wife during a war. He trains Sanjay early in the morning every day by making him do military-style physical work outs (Sanjay seems to be used to this since he had no complaints against this). He says he is not very good at math and this is examplified when he loses count of Timmy Turner's sit-up reps (causing him to start over every time he loses count) and that is why he joined the military.
