Hal Hunt is the typical hero: tall, handsome and muscular, but still fast on his feet despite his broad build. He has survived an attack by a Portuguese man o' war and fought and defeated a panther unarmed and single-handedly. With remarkably little practice, he learns to hold his breath underwater for more than 2 minutes while diving for pearls in the South Seas. He also has a scar on his shoulder blade caused by a spear, courtesy of Merlin Kaggs. He's the older and more mature of the two brothers, and is often left in charge of the mission when their father is absent.
