A brief explanation of the Doc Savage world:

Clark Savage Jr., known by his friends and the general public as "Doc" Savage, was trained by his father, a team of scientists and several specialists from around the world to be a righter of wrongs, a protector of the innocent and an opponent to evil-doers. He was trained in every aspect, and was a physician, surgeon, scientist, adventurer, inventor, explorer and researcher. He was mentally and physically trained to become a sort of "super-man," and even had his own "Fortress of Solitude" five years before Jerry Siegel and Joe Shuster came up with the idea of Clark Kent. He travels the earth, seeking out those in need of his help and those in need of punishment.

On his adventures, Doc is accompanied by up to five assistants, often called the Fabulous Five. Doc and his five assistants first met together at the POW camp Loki during the Great War.

Lieutenant Colonel Andrew Blodgett "Monk" Mayfair: a brilliant chemist, Monk got his nickname from his simian appearance, most obviously his arms, which are six inches longer than his legs. He is little over five feet tall, with red hair and a chest thicker than it is wide. He's in a constant state of friendly fighting with Ham Brooks, which originated during the Great War when Ham taught Monk some French words to say to an officer. The words turned out to be a string of insults, which resulted in a stay in the guardhouse.

Brigadier General Theodore Marley "Ham" Brooks: an accomplished attorney, considered one of the best-dressed men in the world. He is never without his black sword-cane, whose blade is coated in a fast-acting anesthetic. His strange nickname was acquired when, in response to his imprisonment in the guardhouse, Monk framed Brooks on a charge of steamling hams from the commissary. "Ham" was convicted in the only case he ever lost.

Colonel John "Renny" Renwick: a construction engineer and architect, Renny is a giant of a man, nearly as tall as Doc himself. His fists are enormous and contribute to an eccentric pastime - knocking out the panels of heavy wooden doors. His expressions work in reverse: as his look of depression deepens, the happier he is. His favorite expression of exclamation is "holy cow."

Major Thomas J. "Long Tom" Roberts: an electrical engineer. Long Tom got his nickname from employing the use of a long tom cannon in defense of a French village during the Great War. Sickly looking and often compared to death walking, Long Tom has rarely, if ever, been ill, and can fight like a wildcat.

William Harper "Johnny" Littlejohn: an archeologist, geologist and topographer. He will never use small words when he can use big ones - "I'll be super amalgamated!" is a favorite expression. During the Great War, he was tortured and as a result lost sight in his left eye. A monocle or a pair of glasses (the left lens of which was thicker and served as a magnifying glass) was worn by Johnny in the early years. Later, Doc performed corrective surgery that restored his sight.

Patricia "Pat" Savage: Doc's cousin, she has sthe same bronze skin and hair and golden eyes as he does. Despite Doc's best efforts to keep her away from danger, Pat likes to tag along on many of his adventures. She often gets frustrated when Doc discourages or prevents her from coming, the reason often being that she is female.

The character and world view of Doc and his five companions is displayed in his oath:

"Let me strive every moment of my life to make myself better and better, to the best of my ability, that all may profit by it. Let me think of the right and lend all my assistance to those who need it, with no regard for anything but justice. Let me take what comes with a smile, without loss of courage. Let me be considerate of my country, of my fellow citizens and my associates in everything I say and do. Let me do right to all, and wrong no man."
