Whereas Doc Savage was known as “The Man of Bronze”, the Avenger was described as “The Man of Steel”. The Avenger's “marksman's eyes” echoed the “burning eyes” of the Shadow, who continued to be referred to as “The Masked Avenger.” When creating the Avenger, Paul Ernst drew on elements from characters he had previously created; Seekay (a private detective with a disfigured face who wears a plastic mask); the Wraith (a crimefighter who used a knife and a gun); Dick Bullitt (with gray features); Old Stone Face (a G-man with the emotionless visage); the Gray Marauder and Karlu the mystic.

Biggles first appears as a teenaged “scout” (fighter) pilot in the Royal Flying Corps (RFC) during World War I. He has joined the RFC in 1916 at the young age of 17, having conveniently “lost” his birth certificate. Biggles represents a particularly “British” hero, combining professionalism with a gentlemanly air. Under the stress of combat he develops from a slightly hysterical youth prone to practical jokes to a calm, confident, competent leader. He is occasionally given “special” (secret) missions by the shadowy figure of Colonel (initially “Major”) Raymond (Wing Commander or Air Commodore in later books, reflecting the creation of the Royal Air Force with its own ranks), who is already involved with the intelligence side of operations.

Biggles is accompanied by his cousin Algernon ('Algy') Lacey and his mechanic Flight Sergeant Smyth, who are to accompany Biggles on his adventures after the war; added to the team in 1935 is the teenager Ginger Hebblethwaite.

The Continental Op is a private investigator employed as an operative of the Continental Detective Agency's San Francisco office. His name is never mentioned in any story. The Continental Op is a master of deceit in the exercise of his profession. In “$106,000 Blood Money”, for instance, the Op is confronted with two dilemmas: shall he expose a corrupt fellow detective, thereby hurting the reputation of his agency; and shall he also allow an informant to collect the $106,000 reward in a big case even though he is morally certain — but cannot prove — that the informant has murdered one of his agency's clients? The Op resolves his two problems neatly by manipulating events so that the corrupt detective and the informant get into an armed confrontation in which both are killed. Decades of witnessing human cruelty, misery, and ruin, as well as being instrumental in sending hundreds of people to jail, or to the gallows, have greatly weakened the Op's natural sympathy with his fellow men. He fears becoming like his boss, “The Old Man”, whom he describes as “a shell, without any human feelings whatsoever”.

Doc Savage's real name was Clark Savage, Jr. He was a physician, surgeon, scientist, adventurer, inventor, explorer, researcher, and a musician. A team of scientists assembled by his father deliberately trained his mind and body to near-superhuman abilities almost from birth, giving him great strength and endurance, a photographic memory, a mastery of the martial arts, and vast knowledge of the sciences. Doc is also a master of disguise and an excellent imitator of voices. “He rights wrongs and punishes evildoers.” Dent described the hero as a mix of Sherlock Holmes' deductive abilities, Tarzan's outstanding physical abilities, Craig Kennedy's scientific education, and Abraham Lincoln's goodness. Dent described Doc Savage as manifesting “Christliness.” Doc's character and world-view is displayed in his oath, which goes as follows

“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. ”

Lieutenant Colonel Andrew Blodgett “Monk” Mayfair, an industrial chemist. Monk got his nickname from his simian build, notably his long arms, and his covering of red hair. He is in a constant state of “friendly feuding” with “Ham” Brooks. This began when his friend taught him some French words to say to an officer and Monk repeated them, not knowing they were a string of insults. The result was a lengthy stay in the guardhouse.

Brigadier General Theodore Marley “Ham” Brooks, an accomplished attorney. Ham was considered one of the best-dressed men in the world, and as part of his attire, carried a sword cane whose blade is dipped in a fast-acting anesthetic. His nickname was acquired when Monk, in retaliation for his guardhouse incarceration, framed Brooks on a charge of stealing hams from the commissary. In the only case which Ham ever lost, he was convicted of stealing the hams.

Colonel John “Renny” Renwick, a construction engineer. Renny was a giant of a man, with “fists like buckets of gristle and bone.” His favorite pastime was knocking the panels out of heavy wooden doors. He always wore a look of depression, which deepened the happier he grew.

Major Thomas J. “Long Tom” Roberts, an electrical engineer. “Long Tom” got his nickname from using an antiquated cannon of that nickname in the successful defense of a French village in World War I. Long Tom was a sickly-looking character, but fought like a wildcat.

William Harper “Johnny” Littlejohn, an archaeologist and geologist. Johnny had an impressive vocabulary, never using a small word when a big one could suffice. (“I'll be superamalgamated!” was a favorite expression). Johnny wore eyeglasses with a magnifying lens over his left eye in early adventures (that eye having been damaged in World War I). Doc later performed corrective surgery that restored Johnny's sight in that eye, but Johnny retained the magnifier as a monocle for use both as a magnifying glass and as a memento.

Doc's cousin Patricia “Pat” Savage, who has Doc's bronze skin, golden eyes, and bronze hair, also was along for many of the adventures, despite Doc's best efforts to keep her away from danger. Pat chafes under these restrictions, or indeed any effort to protect her simply because she is female. She is also able to fluster Doc, even as she completely charms Monk and Ham.

The novels are set in a dark, fog-shrounded version of Washington, D.C. Yen Sin, described as the “Yellow Doctor” and the “Invisible Emperor”, combines the mysticism of the East with the latest devices of the West with diabolical results. He uses blow guns, Dacoit stranglers, death rays and science laboratories to achieve his evil ends. He is opposed by Michael Traile, a man who is incapable of natural sleep (owing to a bungled brain operation) and who has to resort to periodic yoga-like relaxation sessions in order to recharge his vitality.

The Domino Lady is really University of California, Berkeley-educated socialite Ellen Patrick. When her father, District Attorney Owen Patrick, is murdered she puts on a domino mask and a backless white dress to avenge him. She would arm herself with a .45 pistol and a syringe full of knockout serum, but often her best weapon was her beauty, which often distracted and entranced opponents, or at the very least led them to underestimate her, allowing her to outwit them. Such wiles rarely worked upon her female adversaries, however. She steals from her targets, donating most of the profits to charity after deducting her cut, and leaves a calling card with the words “Compliments of the Domino Lady”.

The Eel is a gentleman thief of “courageous action and questionable morals,” The author introduces the character thus: “I like my name, The Eel. People have been calling me that ever since I began working on the theory, years ago, that the world owed me a living and damned if I wouldn't collect it. Matter of fact, the gentry of the law who tagged me with the name now like it a whole lot less than I do. Eels tend to be slippery, no?”

A master criminal, Fu Manchu's murderous plots are marked by the extensive use of arcane methods; he disdains guns or explosives, preferring dacoits, Thuggee, and members of other secret societies as his agents armed with knives, or using “pythons and cobras… fungi and my tiny allies, the bacilli… my black spiders” and other peculiar animals or natural chemical weapons.

Fu Manchu claims to hold doctorates from four Western universities. Emperor Fu Manchu reveals he attended Heidelberg, the Sorbonne, and Edinburgh. Dr. Petrie believed that Fu Manchu was around 70 years old in 1911 at the time of their first encounter. This would have placed Fu Manchu in the West studying for his first doctorate in the 1870s.

Fu Manchu had been a member of the Imperial family who backed the losing side in the Boxer Rebellion. In the earliest books, Fu Manchu is an agent of the secret society, the Si-Fan and acts as the mastermind behind a wave of assassinations targeting Western imperialists. In later books, he vies for control of the Si-Fan which is more concerned with routing Fascist dictators and halting the spread of Communism. The Si-Fan is largely funded through criminal activities, particularly the drug trade and white slavery. Dr. Fu Manchu has extended his already considerable lifespan by use of the elixir vitae, a formula he spent decades trying to perfect.

Opposing Fu Manchu in the early stories are Denis Nayland Smith and Dr. Petrie. They are in the Holmes and Watson tradition, with Dr. Petrie narrating the stories while Nayland Smith carries the fight, combating Fu Manchu more by dogged determination than intellectual brilliance (except in extremis). Nayland Smith and Fu Manchu share a grudging respect for one another, as each believes a man must keep his word even to an enemy. Nayland Smith is a colonial police commissioner in Burma granted a roving commission which allows him to exercise authority over any group that can help him in his mission. He resembles Sherlock Holmes in physical description and acerbic manner, but not in deductive genius. When the series revived, Smith (who has been knighted) is Assistant Commissioner of Scotland Yard. He later resigns this post and accepts a position with British Intelligence. Several books have him placed on special assignment with the FBI.

Prominent among Fu Manchu's agents was the “seductively lovely” Kâramanèh. Her real name is unknown. She was sold to the Si-Fan by Egyptian slave traders while still a child. Kara falls in love with the narrator of the first three books in the series, Dr. Petrie. She rescues Petrie and Nayland Smith many times. Eventually the couple are united and she wins her freedom. They marry and have a daughter, Fleurette, who figures in later novels.

Fu Manchu's daughter, Fah lo Suee, is a devious mastermind in her own right, frequently plotting to usurp her father's position in the Si-Fan and aiding his enemies within and outside of the organisation. Her real name is unknown; Fah lo Suee was a childhood term of endearment. She was known for a time as Koreani after being brainwashed by her father, but her memory was later restored. She is infamous for taking on false identities, like her father, among them Madame Ingomar and Queen Mamaloi.

G-8 was a heroic aviator and spy during World War I. His stories were often outlandish, with many supernatural or science fiction elements. G-8's true identity was never revealed. He had a girlfriend, a nurse who aided his group, and her name as well was never revealed. His English manservant was named Battle. His wing-men were the short Nippy Weston, who flew an aircraft numbered 13, and the tall and muscular but superstitious Bull Martin, whose aircraft was numbered 7. Both of them were Americans. His adventures entailed fighting against the lethal super technology that was constantly created by the Kaiser's mad scientists. Reoccurring villains included Herr Doktor Krueger, the Steel Mask, and Grun.

The Green Lama is an alias of Jethro Dumont, a rich resident of New York City. Born July 25, 1903, to millionaire John Pierre Dumont and Janet Lansing. He received his A.B. from Harvard University, M.A. from Oxford, and Ph.D. from the Sorbonne; he also attended Drepung College in Tibet. He inherited his father’s fortune, estimated at ten million dollars, when his father and mother were both killed in an accident while he was still at Harvard. Spent ten years in Tibet studying to be a lama (a Buddhist Spiritual Teacher) and learning many mystical secrets in the process. He returned to America intending to spread the basic doctrines of Tibetan Buddhism (remove ignorance and relieve suffering), but realized that he could accomplish more by fighting crime. He never carried a gun, believing that “this would make me no better than those I fight.” Dumont was also endowed with superhuman powers acquired through his scientific knowledge of radioactive salts. Dumont has two alter egos: the crime-fighting Green Lama, and the Buddhist priest Dr. Pali. He also had additional alter-egos including the adventurer “Hugh Gilmore.” Among the Green Lama's litany of associates were a Tibetan lama named Tsarong, the college educated reformed gangster Gary Brown, the post-debutant Evangl Stewart (who would go on to marry Gary), radiologist Dr. Harrison Valco, New York City police detective John Caraway, actor Ken Clayton, Montana-born actress Jean Farrell, and magician Theodor Harrin. The Green Lama was also frequently assisted by the mysterious woman known as “Magga”, whose true identity was never revealed. Crossen's pseudonym “Richard Foster” was also established as a character and friend of Jethro Dumont.

Jim Anthony was described as “half Irish, half Indian, and all-American”. He inherited great wealth and physical attributes. He could see in the dark, was super strong, and had a sixth sense. He excelled in several subjects, including physics, psychiatry, and electro-chemistry. He owned businesses around the country, including the Waldorf-Anthony Hotel in New York, where he maintained a penthouse apartment and secret laboratory. There was also the Tepee, his hidden mansion in the Catskills Mountains, and the Pueblo in the southwest, a hotel/resort built at an oasis by Anthony. His father was Shean Boru Anthony, an Irishman who had traveled the world as an adventurer, becoming rich in the process. His mother was Fawn Johntom, daughter of a Comanche chief.

Anthony was aided by several others: Tom Gentry, large, Irish, served as chief pilot, chauffeur and man Friday. Dawkins, English butler. Mephito, Anthony's grandfather, a Comanche shaman who guarded the Tepee. Delores Colquitte, daughter of Senator Colquitt and Anthony's love interest.

Born in South Africa in 1918, three-year-old David Rand accompanied his British parents John and Constance on a flight to Cairo to visit his grandfather. Unfortunately, their plane crashed in the jungles of Congo. Constance died in the crash and John was driven mad. Living in the jungle with his father, isolated from the local tribes, David grew under the jungle’s hardships into an unusually powerful youth and developed strong empathy with wildlife, notably rescuing Zar the Lion from quicksand. When a criminal named Paul de Kraft discovered emeralds in Congo, John died opposing him only for Zar to scare Paul de Kraft off. With the support of Zar, David became the jungle's leading warrior within a few years challenging different animals like Bardak the Ape and N'Jaga the Leopard. Considered to be “god-like” by the natives, David Rand ended up named Ka-Zar (native for “Brother of Zar”). When Paul de Kraft returned to seize the emerald deposits, Ka-Zar killed him thus avenging his father. With the help of the local animals, Ka-Zar established himself as the guardian of the jungle which involved meting out harsh retribution to any intruder seeking to exploit his resources-but he frequently aided more benign explorers, such as when he protected Prof. Rice and his daughter Mara from the criminal pilot “Red” Skelton, rescued Rita Grey from the Wabi tribe, and helped two Scotland Yard detectives capture murderer London Jack. When Zar the Lion was captured by the vicious Rajah Sarput and a big game hunter named Bradley, Ka-Zar stowed away on a ship when Zar was shipped to the United States. Though he managed to free Zar, Ka-Zar ended up arrested when he tried to free the zoo animals. Fortunately, Ruth Wilson (another woman whom Ka-Zar had rescued during an African expedition), vouched for him. Ka-Zar and Zar were granted passage back to Africa on a British ship. Surviving attacks by entrenched Nazi forces, Ka-Zar and Zar confronted Sarput who was ultimately slain by their ally Trajah the Elephant. Soon after, Ka-Zar learned he had inherited his father’s Transval diamond mines. After preventing his inheritance’s theft by John Rand’s law partner Alec Wright, donated the wealth to war relief in England. While on an expedition to the mysterious Black River Region, Ka-Zar encountered giants and subterranean lizard people. Ka-Zar managed to befriend a giant named Bogat. Ka-Zar later waged a series of campaigns against the Axis forces in Ethiopia, Somaliland, and anywhere else in Africa where the Axis forces were camped killing them with their own weapons with help from the French and British forces. Following one such encounter, Ka-Zar was restored to health by an aged witch doctor, who gave him a brew used centuries before to grant his tribe superhuman strength, Ka-Zar’s exploits earned him such fame that he was invited to attend a meeting of superhuman champions in mid-1940s. Last time anyone heard from Ka-Zar, he protected his region’s wildlife when Africa was threatened by monstrous tidal waves from Atlantean warfare. The rest of Ka-Zar's life after that was left unchronicled.

The Moon Man was so named because he concealed his identity with a spherical helmet of argus glass, which gave a mirrored appearance. He wore a black robe with black gloves. Because the Moon Man robbed from villains, he was viewed by the police as another criminal. All the loot he took was instead distributed secretly to the poor of Great City by the Moon Man's ally, Ned “Angel” Dargan. The Moon Man was really detective-sergeant Stephen Thatcher, son of Great City's Police Chief. His main opponent was Detective Gill McEwen, who worked to stop the Moon Man. Sue McEwen, Gill's daughter, was Thatcher's love interest.

Jimmy Christopher was a secret agent, codename “Operator No. 5” for the United States Intelligence in a series about America's enemies who pledged war, death and bloody destruction in their efforts to take over America. The enemies were many, but often from countries with fictional names. Christopher had two trademarks: a skull ring and a rapier which was kept curled inside his belt. He was aided by a number of people in the various wars: Diane Elliot, his girlfriend; Tim Donovan, who quickly grew from a youngster to a two fisted young man; Nan Christopher, his twin sister; John Christopher, his father who was a retired operative known as Q-6; Chief of Intelligence Z-7; and friend “Slips” McGuire, among many others, some of whom gave their lives for America.

The Phantom is actually the wealthy Richard Curtis Van Loan. The Phantom is introduced as a world-famous detective, whose true identity is only known by one man — Frank Havens, the publisher of the Clarion newspaper. Richard Curtis Van Loan is orphaned at an early age, but inherits wealth. Before World War I, he leads the life of an idle playboy, but during the war he becomes a pilot and downs many German planes. After the war, Van Loan has a difficult time returning to his old life. At the suggestion of his father's friend, Havens, he sets out to solve a crime that had stumped the police. After solving it, he decides he has found his calling. He trains himself in all facets of detection and forensics, and becomes a master of disguise and escape. He makes a name for himself as the Phantom, whom all police agencies around the world know and respect. When dealing with law enforcement officials he carries a platinum badge in the shape of a domino mask as proof of his true identity. The initial stories were less about a detective than an adventurer using disguise and lucky escapes to conclude his cases. The Phantom employs several alternate identities, including Lester Cornwell and Dr. Paul Bendix, a chemist.

Other people in Van Loan's life include Muriel Havens, Frank Havens' daughter, with whom he is in love, and Clarion reporter Steve Huston. Laurence Donovan introduced a kid sidekick named Chip Dorlan in the 1939 novel, The Sampan Murders. After Pearl Harbor, Chip joins the Army as an Intelligence officer, returning briefly to the series after the war. Van Loan's former mechanic and pilot, Jerry Lannigan, assists him in several cases, as do others from time to time.

Raffles was a Victorian era gentleman thief and a born member of nobility. The first issue of the original German series reveals that the notorious thief John C. Raffles is really Lord Edward Lister. A number of different, somewhat conflicting origin stories exist to explain why a genuine Lord would become a thief, involving having been robbed from his inheritance, poverty in childhood, boredom or overindulgence in charity. With his secret identity exposed Raffles is forced to create and maintain a large number of false ones, of which the main one is Lord William Aberdeen. Depending on the origin story this title could be genuine, the name and identity are false. The character, though originally a sort of a hero villain, grew more and more into a heroic character, a thief, certainly, but a thief like Robin Hood, embodiment of the ideals of the nobility, protecting the weak, punishing and reforming the bad guys (by theft), supporting the poor and often curing the ill. Raffles is a medical doctor, a chemist, an engineer and an inventor. That combination results in his most remarkable ability: Raffles can by means of his medical/chemical knowledge change the colour and texture of his hair and his skin and the colour of his eyes. He used this ability almost exclusively for his own disguises, combined with more conventional disguise tricks. As a result of this his true age is always somewhat unclear. As a very handsome and muscular man he cannot disguise himself as a female person convincingly, unlike his companions, be it that Henderson seems always a remarkably tall and muscular lady. Raffles cannot be hypnotised by normal means, but can hypnotise people himself. Raffles speaks quite some languages, including Dutch, French, Russian and Hungarian. Considering less exceptional abilities, they can be simply summarized by stating that, but for eating with chopsticks, Raffles can do everything. For a Victorian gentleman, Lord Lister is refreshingly free from racist views. Scenes in which topless ladies occur are sometimes noticeable, but those scenes are rather free from erotic implications, as they tend to involve Raffles as a doctor or a detective discovering something clearly of great importance. As such the series was seen as one of the better pulps, not unfit for children. His arch-enemy is the rather incompetent inspector Baxter (Scotland Yard), whose more competent assistant is an admirer of Raffles. Sidekicks to Raffles are the giant James Henderson, his driver and servant, and Charles Brand, his secretary, financial manager and friend. Henderson is very strong, he lifts 800 kg with ease and a good hand to hand fighter. Charles Brand however is the best shot and the fastest runner of the three, as well as the only one who can disguise himself convincingly as a girl or a woman. Relations between the three are warm, but Lord Lister is the master.

The true identity of Secret Agent X is never revealed. He is a master of disguise, known as “the man of a thousand faces”, who adopts several different identities in each story. Although he is a dedicated crime-fighter working undercover for the U.S. government, this is unknown to the police who consider him an outlaw. His true role is known only to newspaper reporter Betty Dale and his mysterious Washington controller, K-9. Agent X come close to being undone once by a woman who could recognise him no matter what his disguise. She turned out to be blind and recognised his manner of walking. Originally X was bank-rolled by an anonymous group of millionaires who made any amount of money he might need available. He maintained a number of identities and had bank-rolled a failing detective business into a thriving business where alongside their usual work, they did work for him, gathering news reports, getting information, leg work, guarding people, etc. They did not know his real identity. Later X became more of a mysterious government figure. His weapon of choice was a gas gun which quickly rendered people unconscious for a short time without any side effects.

The Shadow was an invisible avenger who had learned, while “traveling through East Asia,” “the mysterious power to cloud men's minds, so they could not see him.” The character was given the power to escape human sight. In order to explain this power, The Shadow was described as a master of hypnotism. The Shadow's real identity is Kent Allard, a famed aviator who fought for the French during World War I. He became known by the alias the Black Eagle, although later stories revised this alias as the Dark Eagle. After the war, Allard finds a new challenge in waging war on criminals. Allard fakes his death in the South American jungles, then returns to the United States. Arriving in New York City, he adopts numerous identities to conceal his existence. One of these identities—indeed, the best known—is Lamont Cranston, a “wealthy young man about town.” Cranston is a separate character; Allard frequently disguises himself as Cranston and adopts his identity. While Cranston travels the world, Allard assumes his identity in New York. In their first meeting, Allard/the Shadow threatens Cranston, saying he has arranged to switch signatures on various documents and other means that will allow him to take over the Lamont Cranston identity entirely unless Cranston agrees to allow Allard to impersonate him when he is abroad. Terrified, Cranston agrees. The two men sometimes meet in order to impersonate each other. The disguise works well because Allard and Cranston resemble each other. His other disguises include businessman Henry Arnaud; elderly Isaac Twambley; and Fritz; in this last disguise, he pretends to be a doddering old janitor who works at Police Headquarters in order to listen in on conversations.

The Spider was in actuality millionaire playboy Richard Wentworth (who had been a Major in World War I), living in New York and unaffected by the Great Depression. Wentworth fought crime by donning a black cape and slouch hat. Later vampire-like makeup appeared and then a face mask with grizzled hair and hunchback were added to terrorize the criminal underworld with The Spider's brand of violent vigilante justice. Wentworth also ventured, at times, into the underworld disguised as small time hood, Blinky McQuade, to gain needed information. The stories often involved a bizarre menace and a criminal conspiracy and were often extremely violent, with the villains engaging in wanton slaughter of thousands as part of sometimes nationwide crime sprees.

Richard Wentworth was aided by his longtime fiancé, Nita Van Sloan. Though they were as close as man and wife, they knew that they could never marry and have a family, as Wentworth believed that he would eventually be unmasked or killed as The Spider, and his wife and family would then pay the price. Nita disguised herself as The Spider a few times, covering for Wentworth when he was seriously injured. Ram Singh, a Sikh (originally Hindu), was Wenthworth's manservant; he was a deadly knife thrower and usually carried several knives with him, including the deadly Kukri. Ram Singh never saw his position as a servant demeaning or having a negative impact on his self-respect, feeling that he served a man totally above other men. Ronald Jackson was Wentworth's chauffeur. Jackson had served under Wentworth in World War I and often referred to him as “the Major”. Harold Jenkyns was Wentworth's butler, a man who had been in the Wentworth family's service for a long time. Wentworth's main ally/antagonist was Police Commissioner Stanley Kirkpatrick or simply “Kirk”, who suspected Wentworth was The Spider but could never prove it. An old war colleague and inventor named Professor Ezra Brownlee featured heavily in the early Spider novels before being killed. Brownlee's son made some appearances afterwards, taking over for his late father.

Tarzan is the son of a British lord and lady who were marooned on the Atlantic coast of Africa by mutineers. When Tarzan was only an infant, his mother died of natural causes and his father was killed by Kerchak, leader of the ape tribe by whom Tarzan was adopted. Tarzan's tribe of apes is known as the Mangani, Great Apes of a species unknown to science. Kala is his ape mother. Tarzan is his ape name; his real English name is John Clayton, Viscount Greystoke. In fact, both Clayton and Greystoke may be fictitious names – implying that, within the fictional world that Tarzan inhabits, he may have a different real name. As a young adult, Tarzan meets a young American woman, Jane Porter. She, her father, and others of their party are marooned on exactly the same coastal jungle area where Tarzan's biological parents were twenty years earlier. When Jane returns to America, Tarzan leaves the jungle in search of her, his one true love. Tarzan and Jane marry. He lives with her for a time in England. They have one son, Jack, who takes the ape name Korak (“the Killer”). Tarzan is contemptuous of the hypocrisy of civilization, and he and Jane return to Africa, making their home on an extensive estate that becomes a base for Tarzan's later adventures.
