Descendants of the Meteor Strike
These families intermarried in the following generations, reinforcing the gene mutated by the radiation of the meteor, eventually producing what Farmer calls a “nova of genetic splendor, this outburst of great detectives, scientists, and explorers of exotic worlds, this last efflorescence of true heroes in an otherwise degenerate age.”
The heroic contributors and inheritors of this gene are members of the Wold Newton Family, including:
Solomon Kane; Captain Blood; The Scarlet Pimpernel; Harry Flashman; Sherlock Holmes; Captain Nemo; Phileas Fogg; The Time Traveler; Tarzan and his son Korak; A.J. Raffles; Professor Challenger; Richard Hannay; Bulldog Drummond;Sir Denis Nayland Smith; G-8; The Shadow; Sam Spade; Doc Savage, his cousin Pat Savage, and one of his five assistants, Monk Mayfair; The Spider; Nero Wolfe; Mr. Moto; The Avenger; Philip Marlowe; James Bond; Lew Archer; and Travis McGee
And the villainous ones: 
Fu Manchu, Professor Moriarty, Carl Peterson, and Ernst Stavro Blofeld.
