Also called the Patternmaster series, fully contained in the Seed to Harvest omnibus, the Paternist series is a science fiction tetralogy written by Octavia Butler. The series spans the appearance and rise of powerful psychics among the human race as well as the invasion of the Clayarks, containing the books Wild Seed, Mind of My Mind, Clay's Ark, and Patternmaster, in chronological order, though Patternmaster was written first.
This series contains examples of:
After the End: Mind of My Mind heralded the end of the world as we know it, From Bad to Worse in Clay's Ark, and Patternmaster took place in a future so alien it might as well be a different planet.
Bizarre Alien Biology: The "Clayarks" were orginally humans infected by an alien virus. Infected humans just turn pale and thin, but their children...
Blessed with Suck: Telepath-type psychics rarely learn to completely control their power, constantly being bombarded by other people's thoughts, emotions, and even dreams. They tend to slowly turn anti-social and unstable, even unable to raise their own children. By the time of Patternmaster, all psychics give up their children to boarding schools, where they're raised by special psychics who can handle them. The children usually never meet their own parents.
Body Surf: Doro's power to jump between bodies is completely instinctive, and also undirected. He always jumps into the nearest human being, even if he cannot see them. Despite the fact that he is essentially devouring the souls of the people he jumps into, he really does not care about this and will, for example, jump into somebody else to get across a river simply because it is convenient. The bodies he steals start to deteriorate soon after he enters them and he cannot use any psychic powers the victim may have possessed.
Death Activated Superpower: How Doro became what he was. His probable power was going to be some kind of Telepathy, but he died from the physical strain when it manifested. This warped his talent into the ability to Body Surf instead. He has been jumping from body to body for thousands of years, and he always jumps to the nearest person should his current body be injured or die.
Eldritch Abomination: Doro. He's an ancient psychic predator that eats people's minds and steals their bodies. He can sense other psychics, and it's his life's work to track them down for his selective breeding program. The only morality he follows is "Obey me," and he won't think twice about devouring anyone, ANYONE who crosses him or tries to escape him.
His "true" daughter Mary stops just short, preferring to draw other psychics into a "pattern" so she can feed off them evenly instead of killing anyone...whether they like it or not. She can also siphon other psychic's mental energy to use as her own, which allows her to fend off and absorb Doro. Her progeny become the titular Patternists.
Feudal Future: An interesting variation has been reached by the timeframe of Patternmaster. It is true feudalism in the sense that powerful Patternists form households in which they rule over a territory populated by ordinary humans and weaker Patternists, which they protect against the mutant "Clayark's". Sometimes particularly powerful Patternists will even dominate others who have their own households. Above everyone is the Patternmaster, who controls the Pattern and by extension all of the Patternists. Society has regressed to a comparatively primitive level because most Patternists do not bother to pursue extensive education in anything other than psychic powers and their human slaves are not encouraged to be very innovative. Patternists find it difficult to believe that humanity was once a great deal more technologically advanced.
Grand Theft Me: Doro does this by devouring the host's mind, and abandons the old body to die. Mary's the only one who's ever been able to stop him, and Doro can't even stop himself from switching bodies if he's badly injured or frightened. People who have known him long enough can identify him in any body.
Later Patternists tune this into a fine art, allowing them to temporarily take control of another psychic's body and mental abilities to use in tandem with their own.
Growing Up Sucks: Normally around young adulthood, a psychic will go through a kind of puberty wherein their bodies fall into a wreck and their abilities drastically increase, forcing them to handle their own abilities before they die of the strain. It is not unheard of for psychics to kill themselves or loved ones, forcing those same loved ones to put them down. Doro himself died during this, and it somehow warped his burgeoning power (which was supposed to be some form of telepathy) into the body surfing power he ultimately manifested.
Immortality Immorality: Despite the general horror of what he is, a bodiless entity that survives by devouring other people's bodies and souls, Doro actually wants to create other beings like himself. This is the goal towards which he continues to focus his breeding program, despite it producing people with a wide range of other potentially beneficial powers like telekinesis or psychic healing, all of which he considers to be of little value.
Mental Fusion: The Pattern. It connects all the telepaths, enabling them to co-exist, whereas originally they had been unable to endure each other's proximity. It also provides great power to the Patternmaster, who controls the whole network.
Moral Sociopathy: Thousands of years of body surfing has made Doro extremely amoral and he really just does not care about how his plans (or existence) affect other people.
Never Mess with Granny: Anyanwu is several hundred years old, but it doesn't show unless she allows it and it has no affect on her ability to produce supernatural strength. The last group of young idiots who that their could jump an old witch got straight-up eaten.
Psychic Powers: Doro's breeding program produces people with a wide range of different powers. He is looking to produce something similar to himself. What he gets is not what he wants.
Secret Keeper: Doro has people all over the world who handle business affairs for him.
Self-Made Orphan: Doro. His parents were the first people he ever absorbed, out of simple fear and confusion.
Shapeshifting: Anyanwu's hat trick, written as the culmination of her cellular manipulation abilities. She can make subtle changes like increasing her strength and agility, changer her sex, even turn into a different animal completely.
Shapeshifter Baggage: Averted. It is explained that Anyanwu, and later healer-type psychics, can grow, regenerate, and absorb cells at will.
Humanshifting: Anyanwu, healer-type psychics are implied to be capable of this, though it's much more difficult for them.
Supernatural Elite: The Patternists rule what remains of humanity, presumably including those with psychic powers other than telepathy.
Technically Living Zombie: The Clayarks more or less. The topic is one of some debate, as some aspect of the alien virus prevents most Patternists from reading or controlling the Clayark's minds (although they can still fry their brains). Evidence suggests that the Clayarks do retain some remnant of human sentience, although their predatory impulses and instinctive need to spread their disease make chatting them up unrealistic.
The Virus: The alien disease brought back to Earth on the spaceship Clay's Ark. The victims and their descendents become the bestial "Clayark's".
Zombie Apocalypse: Basically what happened to civilization on Earth when the "Clayark" virus spread. The Patternists were able to carve out reasonably secure fiefdoms due to being able to kill the "Clayarks" with their psychic powers. But even they must constantly be on guard against attacks.
