10. Valentin Michael Smith from A Stranger in a Strange Land by Robert A. Heinlein

Rounding out the top 10 list is Valentine Michael Smith from the book A Stranger in a Strange Landby Robert A. Heinlein.

Robert Heinlein's Hugo Award-winning all-time masterpiece, the brilliant novel that grew from a cult favorite to a bestseller to a science fiction classic.

Raised by Martians on Mars, Valentine Michael Smith is a human who has never seen another member of his species. Sent to Earth, he is a stranger who must learn what it is to be a man. But his own beliefs and his powers far exceed the limits of humankind, and as he teaches them about grokking and water-sharing, he also inspires a transformation that will alter Earth’s inhabitants forever…

9. Roland Deschain from The Dark Tower series by Stephen King

At number 9 is #1 national bestseller, The Gunslinger which introduces readers to one of Stephen King’s most powerful creations, Roland of Gilead: The Last Gunslinger. He is a haunting figure, a loner on a spellbinding journey into good and evil. In his desolate world, which mirrors our own in frightening ways, Roland tracks The Man in Black, encounters an enticing woman named Alice, and begins a friendship with the boy from New York named Jake.

Inspired in part by the Robert Browning narrative poem, “Childe Roland to the Dark Tower Came,” The Gunslinger is “a compelling whirlpool of a story that draws one irretrievable to its center” (Milwaukee Sentinel). It is “brilliant and fresh…and will leave you panting for more” (Booklist).

8. R. Daneel Olivaw from Isaac Asimov's Robot and Foundation series.

R. Daneel Olivaw is a fictional robot created by Isaac Asimov. The “R” initial in his name stands for “Robot,” a naming convention in Asimov's future society. Daneel appears in Asimov's Robot and Foundation series, most notably in the novels The Caves of Steel, The Naked Sun, The Robots of Dawn, Robots and Empire, Prelude to Foundation, Forward the Foundation, Foundation and Earth as well as the short story “Mirror Image”. He is constructed immediately prior to the age of the Settlers, and lives at least until the formation of Galaxia, thus spanning the entire history of the First Empire, the Second Empire run by the Second Foundation, and finally the group consciousnesses of Galaxia, although this last is uncertain as no book about this was ever written.

7. Andrew “Ender” Wiggin from Ender's Game by Orson Scott Card

“Ender's Game tells the story of a young boy, Ender Wiggin, who is sent to a training academy named Battle School, located in orbit above the Earth, built to train people to become soldiers that will one day battle against a vast alien race known as “Buggers”. Ender goes up there, trying his best to become promoted in the difficult training scheme; his brother and sister are trying to restore the world and to make it a better place. For Ender, the training is tough. He is granted a very special teacher, who will help him to become a commander to save humanity from the Third Invasion.”

Coming in at #7, Andrew “Ender” Wiggin is the main character in Ender's Game by Orson Scott Card, which won the 1985 Nebula Award for Best Novel and the 1986 Hugo Award for Best Novel.

6. Arthur Dent from The Hitchhiker's Guide to the Galaxy by Douglas Adams

“Join Douglas Adams's hapless hero Arthur Dent as he travels the galaxy with his intrepid pal Ford Prefect, getting into horrible messes and generally wreaking hilarious havoc. Dent is grabbed from Earth moments before a cosmic construction team obliterates the planet to build a freeway.”

Nominated as one of America’s best-loved novels by PBS’s The Great American Read, Discover Sci-Fi fans agree, placing Arthur Dent from The Hitchhiker's Guide to the Galaxy by Douglas Adams at #6 on your top list for most iconic sci-fi character.

You'll never read funnier science fiction; Adams is a master of intelligent satire, barbed wit, and comedic dialogue. The Hitchhiker's Guide is rich in comedic detail and thought-provoking situations and stands up to multiple reads. Required reading for science fiction fans, this book (and its follow-ups) is also sure to please fans of Monty Python, Terry Pratchett's Discworld series, and British sitcoms.

5. Honor Harrington from the Honor Harrington series by David Weber

Honor Stephanie Alexander-Harrington is a fictional character created in 1992 by writer David Weber as the heroine of the eponymous “Honorverse“, a universe described in a series of best-selling^[1] military science fiction books set between 4003 and 4025 AD.

Harrington is an officer in the Royal Manticoran Navy (RMN), the space navy of the Star Kingdom of Manticore, an interstellar monarchy that counterbalances its relatively small size with superior space combat technology and capability. She has a genius for tactical command, often overcoming significant odds in critical battles and frequently finding herself at the centre of significant military actions. Her dedication to duty and uncompromising performance results in receiving numerous awards and promotions, earning the respect of interstellar empires, and accumulating implacable enemies. She is a skilled martial artist and through her association with her treecat companion Nimitz, develops an empathic sense that assists her in understanding the emotions of those around her.

4. Lazarus “Woodrow Wilson Smith” Long from multiple Robert A. Heinlein books.

Lazarus Long is a fictional character featured in a number of science fiction novels by Robert A. Heinlein. Born in 1912 in the third generation of a selective breeding experiment run by the Ira Howard Foundation, Lazarus (birth name Woodrow Wilson Smith) becomes unusually long-lived, living well over two thousand years with the aid of occasional rejuvenation treatments.

The Lazarus Long set of books involve time travel, parallel dimensions, free love, individualism, and a concept that Heinlein named World as Myth—the theory that universes are created by the act of imagining them, such that even fictional worlds are real.

3. Paul Atreides from Dune by Frank Herbert

Set on the desert planet Arrakis, Dune is the story of the boy Paul Atreides—who would become known as Muad’Dib—and of a great family’s ambition to bring to fruition humankind’s most ancient and unattainable dream.

A stunning blend of adventure and mysticism, environmentalism and politics, Dune won the first Nebula Award, shared the Hugo Award, and formed the basis of what is undoubtedly the grandest epic in science fiction.

2. HAL-9000 from 2001: A Space Odyssey by Arthur C. Clarke

HAL 9000 is a fictional character and the main antagonist in Arthur C. Clarke's Space Odyssey series. First appearing in the 1968 film 2001: A Space Odyssey, HAL (Heuristically programmed ALgorithmic computer) is a sentient computer (or artificial general intelligence) that controls the systems of the Discovery One spacecraft and interacts with the ship's astronaut crew. Part of HAL's hardware is shown towards the end of the film, but he is mostly depicted as a camera lens containing a red or yellow dot, instances of which are located throughout the ship.

1. Hari Seldon from Asimov's Foundation series

Coming in at #1, Hari Seldon from Isaac Asimov's Foundation series is your choice for most epic sci-fi character of all time. This comes as no surprise, as you also voted Asimov's Foundation trilogy as your #1 pick for top sci-fi book of all time in a recent poll (click here to view the complete list).

In his capacity as mathematics professor at Streeling University on the planet Trantor, Seldon develops psychohistory, an algorithmic science that allows him to predict the future in probabilistic terms. On the basis of his psychohistory he is able to predict the eventual fall of the Galactic Empire and to develop a means to shorten the millennia of chaos to follow. The significance of his discoveries lies behind his nickname “Raven” Seldon.

In the first five books of the Foundation series, Hari Seldon made only one in-the-flesh appearance, in the first part of the first book (Foundation), although he did appear at other times in pre-recorded messages to reveal a Seldon Crisis. After writing five books in chronological order, Asimov went back with two books to better describe the initial process. The two prequels—Prelude to Foundation and Forward the Foundation—describe his life in considerable detail. He is also the central character of the Second Foundation Trilogy written after Asimov's death (Foundation's Fear by Gregory Benford, Foundation and Chaos by Greg Bear, and Foundation's Triumph by David Brin), which are set after Asimov's two prequels.

10. The Postman by David Brin

He was a survivor–a wanderer who traded tales for food and shelter in the dark and savage aftermath of a devastating war.  Fate touches him one chill winter's day when he borrows the jacket of a long-dead postal worker to protect himself from the cold.  The old, worn uniform still has power as a symbol of hope, and with it he begins to weave his greatest tale, of a nation on the road to recovery.

Rounding out the top 10 list is “The Postman” by David Brin. This is the story of a lie that became the most powerful kind of truth.  A timeless novel as urgently compelling as War Day or Alas, Babylon (which also made this list), David Brin's The Postman is the dramatically moving saga of a man who rekindled the spirit of America through the power of a dream, from a modern master of science fiction.

9. The Road by Cormac McCarthy

“A father and his son walk alone through burned America. Nothing moves in the ravaged landscape save the ash on the wind. It is cold enough to crack stones, and when the snow falls it is gray. The sky is dark. Their destination is the coast, although they don't know what, if anything, awaits them there. They have nothing; just a pistol to defend themselves against the lawless bands that stalk the road, the clothes they are wearing, a cart of scavenged food—and each other.”

At number 9, Pulitzer Prize winning novel The Road by Cormac McCarthy is the profoundly moving story of a journey. It boldly imagines a future in which no hope remains, but in which the father and his son, “each the other's world entire,” are sustained by love. Awesome in the totality of its vision, it is an unflinching meditation on the worst and the best that we are capable of: ultimate destructiveness, desperate tenacity, and the tenderness that keeps two people alive in the face of total devastation.

8. Farnham's Freehold by Robert Heinlein

“Farnham is a self-made man who sees nuclear war coming and who builds a shelter under his house; only to find it thrust into a strange universe when the bomb explodes. In this future world all civilization in the northern hemisphere has long been destroyed, and Farnham and his family are fit to be slaves under the new regime.”

Heinlein's story is as engrossing now as it was in its original form decades ago. In it, a nuclear holocaust throws a brave and tough-minded family into a future where they are considered traitors and sub-humans and where they must fight tooth-and-claw to avoid becoming slaves to the benighted survivors of the war.

7. Alas, Babylon by Pat Frank

““Alas, Babylon.” Those fateful words heralded the end. When a nuclear holocaust ravages the United States, a thousand years of civilization are stripped away overnight, and tens of millions of people are killed instantly. But for one small town in Florida, miraculously spared, the struggle is just beginning, as men and women of all backgrounds join together to confront the darkness.”

Coming in at #7, “Alas, Babylon,” is a harrowing, human story published 50 years ago, in 1959. The novel, set in a small Florida town after a nuclear attack on the United States, was an instant hit. It’s been reprinted many times; it’s found on high school reading lists; and it’s invariably put high on lists of the best post-apocalyptic fiction – including this one.

6. The War of the Worlds by H.G. Wells

“Shortly after astronomers observe explosions on the surface of Mars, meteor-like objects begin crashing into Earth. Martians emerge from their craters in large tripods, wiping out army units with heat-rays as they roam the English countryside. When the order is given to evacuate London, all seems lost. But there is one minor detail that the Martians did not plan for.”

H. G. Wells is credited with the popularisation of time travel in 1895 with The Time Machine, introducing the idea of time being the “fourth dimension” a decade before the publication of Einstein’s first Relativity papers. In 1896, he imagined a mad scientist creating human-like beings from animals in The Island of Doctor Moreau, which created a growing interest in animal welfare throughout Europe. In 1897 with The Invisible Man, Wells shows how a formula could render one invisible, recognizing that an invisible eye would not be able to focus, thus rendering the invisible man blind. With The War of the Worlds in 1898, Wells established the idea that an advanced civilization could live on Mars, popularising the term ‘martian’ and the idea that aliens could invade Earth.

5. Fahrenheit 451 by Ray Bradbury

“Guy Montag is a fireman. In his world, where television rules and literature is on the brink of extinction, firemen start fires rather than put them out. His job is to destroy the most illegal of commodities, the printed book, along with the houses in which they are hidden. 

Montag never questions the destruction and ruin his actions produce, returning each day to his bland life and wife, Mildred, who spends all day with her television “family.” But then he meets an eccentric young neighbor, Clarisse, who introduces him to a past where people didn’t live in fear and to a present where one sees the world through the ideas in books instead of the mindless chatter of television. 

When Mildred attempts suicide and Clarisse suddenly disappears, Montag begins to question everything he has ever known. He starts hiding books in his home, and when his pilfering is discovered, the fireman has to run for his life.”

Coming in at #5, Ray Bradbury’s internationally acclaimed novel Fahrenheit 451 is a masterwork of twentieth-century literature set in a bleak, dystopian future. 

4. A Canticle for Leibowitz by Walter M. Miller, Jr

“Down the long centuries after the Flame Deluge scoured the earth clean, the monks of the order of St. Leibovitz the Engineer kept alive the ancient knowledge. In their monastery in the Utah desert, they preserved the precious relics of their founder: the blessed blueprint, the sacred shopping list and the holy shrine of fallout shelter.

Watched over by an immortal wanderer, they witnessed humanity's rebirth from ashes, and saw reenacted the eternal drama of the struggle between light and darkness, life and death.”

Coming in at #4, “A Canticle for Leibowitz” was one of the first novels to escape from the science-fiction ghetto and become a staple of high-school reading lists. Its legacy can be seen in the works of Gene Wolfe, Margaret Atwood, and many other speculative-fiction authors who came after him, as well as in the current flood of end-of-the-world novels, TV shows, and movies.

3. Childhood's Ends by Arthur C. Clarke

“In the near future, enormous silver spaceships appear without warning over mankind's largest cities. They belong to the Overlords, an alien race far superior to humanity in technological development-and their purpose is to dominate the Earth. Their demands, however, are surprisingly beneficial-end war, poverty, and cruelty. Their presence, rather than signaling the end of humanity, ushers in a golden age-or so it seems.”

Originally published in 1953, Childhood's End is Clarke's first successful novel-and is considered a classic of science fiction literature. Its dominating theme of transcendent evolution appears in many of Clarke's later works, including the Space Odyssey series. In 2004, the book was nominated for the Retro Hugo Award for Best Novel.

2. Lucifer's Hammer by Larry Niven and Jerry Pournelle

“In this bestselling novel by the authors of THE MOTE IN GOD'S EYE, a massive comet breaks apart and bombards the Earth, with catastrophic results: worldwide earthquakes, volcanic eruptions, thousand-foot tidal waves and seemingly endless rain… With civilization in ruins, individuals band together to survive and to build a new society.”

Published in 1977, Lucifer's Hammer, #2 on our list, was the first major science fiction novel to try to deal realistically with the planetary emergency of an impact event. It plumbs those depths of fascination on an epic scale, rewarded at the time with sales far beyond the normal expectations of the genre.

1. The Stand by Stephen King

“This is the way the world ends: with a nanosecond of computer error in a Defense Department laboratory and a million casual contacts that form the links in a chain letter of death.

And here is the bleak new world of the day after: a world stripped of its institutions and emptied of 99 percent of its people. A world in which a handful of panicky survivors choose sides — or are chosen. A world in which good rides on the frail shoulders of the 108-year-old Mother Abigail — and the worst nightmares of evil are embodied in a man with a lethal smile and unspeakable powers: Randall Flagg, the dark man.”

Coming in at #1 is Stephen King'sThe Stand, the novel that is now considered to be one of his finest works. But as it was first published, The Stand was incomplete, since more than 150,000 words had been cut from the original manuscript.

Now Stephen King's apocalyptic vision of a world blasted by plague and embroiled in an elemental struggle between good and evil has been restored to its entirety. The Stand : The Complete And Uncut Edition includes more than five hundred pages of material previously deleted, along with new material that King added as he reworked the manuscript for a new generation. It gives us new characters and endows familiar ones with new depths. It has a new beginning and a new ending. What emerges is a gripping work with the scope and moral comlexity of a true epic.

For hundreds of thousands of fans who read The Stand in its original version and wanted more, this new edition is Stephen King's gift. And those who are reading The Stand for the first time will discover a triumphant and eerily plausible work of the imagination that takes on the issues that will determine our survival.
