Starting with the first Doc Savage story in 1933 and running throughout the pulp adventures a group of recurring characters appeared either as Doc's supporting cast or antagonists.

Ham Brooks is one of the characters referred to as "The Fabulous Five", the primary assistants of Doc Savage, and first appears with the full name Theodore Marley Brooks.

The character is presented as a Harvard-educated lawyer, holding the military rank of brigadier general, and known as a dandy. He is also shown as always carrying sword cane with a blade coated with a knock-out chemical.

He is also shown to love fighting with his friend "Monk" Mayfair. This began during World War I, when a practical joke landed Monk in a military jail. Ham had taught Monk some insulting French words, presenting them as compliments. Monk used them while speaking to a French general and got locked in the guard house. Shortly after that, Ham was framed for stealing a truckload of hams, resulting in his insulting nickname. Ham was able to defend himself, but the fact that he was never able to prove that Monk was behind this has always been a source of irritation for him.

During the story "Dust of Death" an odd ape took a liking to Ham. He kept it due to its similarity to Monk. He named it Chemistry, to infuriate Monk. Monk often calls it "the what-is-it", since it looks to be either an ape, chimpanzee, gorilla or baboon, or a mixture.

William Littlejohn is one of the characters referred to as "The Fabulous Five", the primary assistants of Doc Savage, and first appears with the full name William Harper Littlejohn.

The character is presented as geologist and archaeologist and referred to as "Professor". Physically he is described as tall, extremely thin, with black hair and a large nose, and wearing spectacles. In the earlier books he wore a monocle, being blind in one eye from a war injury. Later, Doc restored his full vision with an operation. Johnny still carried the monocle, now converted into a magnifying glass for use in field work.

Within the novels, it is stated that he first met Doc Savage in a prisoner of war camp during World War I. He is the only one of Doc's aides whose military rank is never mentioned. In the book Escape from Loki by Philip José Farmer, it is stated that Johnny was in Germany in a civilian capacity when the war broke out. He was arrested on not entirely falsified espionage charges.
