Four Horsemen of the Apocalypse (Good Omens)

The Four Horsemen of the Apocalypse, otherwise known as the Four Bikers of the Apocalypse in modern times or, the Four Horsepersons of the Apocalypse (given War is female) are major antagonists in the dark fantasy book Good Omens by Terry Pratchett and Neil Gaiman.

War
She is a war correspondent. She always arrives in otherwise peaceful countries and within a week of her arrival, a major political outbreak begins which ends with almost everyone dead. She is a highly successful war correspondent and arms dealer by the name of Scarlett. She displays the powers of seduction and lust mainly, but she can be fearsome and intimidating when crossed.

War appears as a beautiful woman with long flaming red hair, and fittingly wears all red leather with a red motorcycle helmet when she hits the road.

Famine
"A measure of wheat for a penny, and three measures of barley for a penny, and see thou hurt not the oil nor the wine."

- Revelations chapter 6, as Dr. Sable signs his book for his next client

Appearing as a business acumen by the name of Dr. Raven Sable, Famine is the scariest of the Four Horsemen. He is, unlike the others, a highly elegant gentleman in a gray suit, but unlike the others, he is extremely cruel and sadistic, and takes pleasure in his victim's suffering. Unlike the other Horsemen who simply carry out their allotted tasks, Famine seems to actually enjoy the suffering he causes. His character is summed up as: "If you had told him there were starving children in Africa, he'd have felt proud you'd noticed." Famine is presumably second most powerful after his master Death. He is making humanity thinner and dumber through an additive in his food supplies. Those in his presence become extremely hungry, often eating themselves to death.

Pollution
Known as "Chalky", this guy seems to like enjoying wanton acts of violence for the sake of his pleasure. He worked at Chernobyl before the plant blew up. This Horseperson is the most enigmatic, and he appears in human form as an emaciated man with blond hair, clad always in white. His supernatural form appears as a humanoid gigantic form of oil, shape shifting constantly.

Death
Azrael. He who is always. The only known boss of the Four Horsemen and the harbinger of doom. All humanity fear him. For lack of a better voice, HE SPEAKS IN A GRAVEYARD TONE.

He is also impossible to be destroyed.

Role in the novel
The Horsemen appear first in different locations around the planet, awaiting the orders of the Apocalypse. Scarlett is introduced first, decimating an African nation, and then Dr. Sable, who is starving America to death. Next is Chalky, who is clogging up Earth's beauty with oil, while sadistically remarking how beautiful Earth is. Death is Another, mentioned to be everywhere, but not yet in human form.

Next, Scarlett causes a political rebellion and half of her town is shot dead. This heralds the start of the Apocalypse. A mysterious deliveryman is going round delivering a sword, scales, pollution devices and the sycthe to the respective Horsemen, and upon each visitation from the mailman, each Horseman seems vaguely satisfied as if he/she has found a new purpose.

When the Antichrist, Adam Young, is located in Oxfordshire, the Horsemen converge to him. In a storm which heralds the End, the Horsemen converge in a bar, recruiting some eager Hell's Angels bikers on the way. These four wannabe Hell's Angels name themselves the Horsemen's sidekicks before they have a fatal motorway accident leaving only one survivor. Inevitably, Death waits behind to collect their souls.

Stunned police see the Horsemen zoom over an upturned lorry outside London. When the Bikers of the Apocalypse arrive at Oxfordshire, they lament how cool the actual Apocalypse would be in Megiddo, Israel, which literally means Apocalypse. Death says this is the final battle, and its all been planned. He says the professionals need their work cut out.

When they meet a tyrannical village elder who berates Pollution for dropping a crisp packet, Pollution squirms with delight when the elder threatens to drop packets all over Pollution's house.

Pollution heralds the End by shutting down all electricity to the Earth. Chaos ensues. Armies begin to go to war until Adam Young and his outcast friends face the Four Horsepersons and respectively banish them apart from Death, who is the only true immortal one. He rises into the sky, proudly proclaiming he will never be defeated.

Newt Pulsifer returns electricity to the world with Adam's help and foils the Apocalypse.

Personality
Cruel, sadistic monsters, nothing marked the Horsepersons as vaguely human, no matter how hard they masqueraded. They fed off their attributes and loved destruction so much it was second nature.

Death was a fanatic, willing to believe a prophecy for the good of all. He was most eager to see the Apocalypse come about, although Famine and Pollution were both as eager. Pestilence had retired following the discovery of penicillin.
