Apocalypse World

Apocalypse World

It's Earth. But this Earth is locked in eternal war between Heaven and Hell. There are armies of angels fighting hordes of demons, and the few humans that remain are caught in between. – Castiel, 12.23 All Along the Watchtower

Apocalypse World is a version of Earth in an alternate universe, one in which the forces of Heaven and Hell are fighting with humanity caught in the middle. It is connected to the world of the Winchesters by rifts. The point of divergence for the two universes occurred on the night of May 2, 1973. In this world, when offered a deal by the Prince of Hell Azazel to resurrect John Winchester, Mary Campbell refused. As a result, Sam and Dean never existed and thus did not stop the Apocalypse from happening, which went as planned in 2010.

A portal was opened by the birth of the Nephilim Jack. An alternative method to open a rift was discovered by the Apocalypse World version of Kevin Tran, who was able to devise a spell (of which the key ingredient is the grace of an archangel) by studying the angel tablet of that universe, however the spell is designed to admit one traveler at a time. Later, Donatello Redfield was able to locate a different spell in the demon tablet for opening portals, but due to his soullessness, the dark energy within the tablet corrupted him. Castiel was able to strip the spell from Donatello's mind, leaving him brain-dead for over a year. The spell requires four major ingredients: The grace of an archangel, a fruit from the Tree of Life, the Seal of Solomon, and the blood of "a most holy man." Something that has been to the world is required to open the desired rift, which will remain open for 24 hours unless the spell is continuously replenished with archangel grace to extend the rift's lifespan.

History

Map of the United States in Apocalypse World.

In this world the Apocalypse happened, and the battle between Michael and Lucifer has left Earth a barren wasteland littered with the bodies of angels, demons, and humans. Death has been locked away and Michael has enslaved the reapers. Also it appears that while there may be multiple universes there is only one God who created them all. Large angel blade-like spikes can be seen protruding from the ground with bodies impaled on them, while the skies crackle with red lightning. Time appears to move differently, as when Castiel first steps through to the rift during the day, he finds himself on the apocalyptic landscape at night. At some point during the various wars that have gone on, the number of humans appears to have dwindled significantly, particularly females. Once Michael began his extermination of the humans, there was no thought of what would happen to the monsters with a dwindling food source. When starvation set in for the monsters they reverted to a more feral state, operating solely on pure, stupid appetite, while also seemingly going through various physical changes.

Under Michael's rule, the United States is divided into districts and restricted zones: The East Coast is split into "Northeastern" and "Southern Sectors," with Canada designated the "Northern Ice Fields." The Midwest from the Dakotas are designated the "Great Barren Plains," within which Michael's Fortress appears to be located somewhere in the vicinity of Kansas or Nebraska. Montana and Idaho are simply known as "The Void", and Utah, Nevada, Arizona, Colorado, and New Mexico make up the "Western District." The West Coast is simply marked as "The Rebels of California." Texas appears to have kept its name. The states of Pennsylvania, New York, New Jersey, Delaware, and Maryland have been marked as "Zone R4" and the rest of the states on the Northeastern tip of the United States are not present on the map. There is a wall running along the U.S. / Mexico border, where Mexico is simply designated as "South of the Wall." There also appears to be another wall along the U.S. / Canada border extending from the "The Rebels of California" to "The Void." There also appears to be impact/ground zero markings over Detroit and Los Angeles, which are later revealed to be the impact sites of EMP-like blasts that fried all the technology in North America.

Some demons have a physical form on the earthly plane and no longer require vessels, as evidenced when Castiel is attacked by a horned tempter demon. Angels are fierce and brutal, militaristic warriors, as Bobby Singer told Sam and Dean that the only reason he didn't kill Castiel on sight was because "he wasn't wearing a necklace made out of baby ears."

After becoming trapped in this world, Mary Winchester and the Nephilim Jack Kline work alongside a platoon of resistance fighters led by Bobby Singer to protect the remaining human population against Michael and the angels. From a conversation with Bobby, Mary determines that the divergence point between her world and this one was a simple choice in 1973: Mary's Apocalypse World counterpart refused the deal with Azazel to resurrect her deceased lover John Winchester. As a result, Sam and Dean never existed in this world to stop the Apocalypse, which went as planned in 2010.

In 2018, Sam and Dean led an exodus of dozens of humans from Apocalypse World through a portal to their own universe. Among those that made it were Bobby Singer, Charlie Bradbury and Maggie. However, the effort cost the life of Gabriel, who sacrificed himself to stop Michael from passing through the rift while Lucifer was left purposefully stranded by Sam. Lucifer made a deal with Michael to work together to reopen the portal and reach the Winchesters' universe themselves. Apparently abandoning his armies in Apocalypse World, Michael reached the Winchesters' universe with Lucifer. The subsequent conflict with a super-charged Lucifer allowed Michael to gain his true vessel, Dean Winchester and he was set loose upon the Winchesters' world in Dean's body. Months later, Michael was finally killed by Jack using the power of his soul after Jack had lost his grace to Lucifer.

It is eventually destroyed by God along with the rest of the alternate realities over a campaign of several months' time. The only survivors of the population of this entire world are the people still left alive from the exodus in Sam and Dean's world. When Billie plans to take power after the deaths of God and Amara, she intends to send everyone from Apocalypse World back where they belong. Sam states that this is a death sentence as Apocalypse World no longer exists. Billie's plan is foiled with her death, although the Apocalypse World survivors are some of the first targeted by Chuck when he wipes out all life on Earth except for the Winchesters and Jack. After Chuck's defeat, Jack restores everyone that Chuck erased from existence, including the survivors of Apocalypse World.

Characters in Apocalypse World

• Bobby Singer - Still a hunter in the post-Apocalyptic wasteland. This Bobby Singer has a self-described "passion" for hunting angels, for which he uses bullets forged from discarded angel blades, with his trusty machine gun, "Rufus." He also appears to be the leader of an encampment in Dayton, Ohio, consisting of a faction of the remaining humans. In Apocalypse World, Bobby had a son named Daniel while in the Winchesters' world he had no children. Bobby lost Daniel during the Apocalypse and is still haunted by his death. Bobby is currently working as a hunter in the Winchesters' world where Mary Winchester has developed a romantic interest in him that he appears to be too closed off to fully reciprocate.
• Mary Campbell - Killed ten years prior to the present by Azazel. She was a hunter that ran with Bobby Singer, was known to tell the same story about the man she loved, John Winchester, with enough pints of moonshine in her. She was indirectly responsible for creating the world by refusing to make the deal with Azazel to resurrect John, resulting in the Winchesters never existing to stop the Apocalypse. She is described as looking like her counterpart, only a year or two younger.
• John Winchester - Has been dead for over 40 years, due to Mary refusing to make the deal with Azazel in May 1973 to resurrect John, causing Sam and Dean to never be born.
• Azazel - After Azazel killed John, Mary refused to make the deal to bring him back. Bobby would go on to tell Sam and Dean that Azazel killed Mary ten years prior. It is unknown if he survived the Apocalypse that followed Lucifer's rise.
• Michael - Defeated his world's Lucifer, claiming to have ripped him apart over Abilene, Kansas. Michael has become a conqueror, bringing death and destruction to the planet rather than paradise. He is currently creating an army of monsters in Sam and Dean's world to destroy it as he did his own. He is killed and his grace absorbed by Jack Kline after Michael takes Rowena as his vessel.
• Lucifer - Counterpart of the main universe's Lucifer. Due to Sam and Dean Winchester not existing when he rose, the Apocalypse occurred and Lucifer was not locked away again. According to Michael, he tore this Lucifer to pieces in the skies over Abilene, Kansas.
• Kevin Tran - A prophet of the Lord like his counterpart. However, with no God to serve, Kevin believed that he must serve the ranking deity of the world, Michael. Much like his deceased counterpart, Kevin spent his days translating the various tablets to help in Michael's war machine. In 2018, Kevin used himself as a suicide bomber in an attempt to "break" Jack Kline, under Michael's orders, in order to be granted entry into Heaven to be with his mother once again.
• Linda Tran - Mother of Kevin Tran who was killed when the Apocalypse began. A major part of Kevin's motivation for helping Michael is that Michael promises him that he will ensure that Kevin is reunited with Linda in Heaven.
• Zachariah - A subordinate of Michael. Like his counterpart, Zachariah preferred to use mental manipulations to achieve his ends. He is killed by Jack Kline when he attempts to kill Mary Winchester.
• Charlie Bradbury - A fighter in the war against the angels, this Charlie is a member of the human resistance's inner circle. She shares many personality traits with the main universe's Charlie Bradbury.
• Balthazar - Like all angels, this Balthazar served under Michael. In 2018, he lead his army in an attack on Jack and Bobby, but was unprepared for the resistance and was killed by Jack Kline.
• Castiel - With Sam and Dean having never been born, this version of Castiel never rebelled against the angels or stopped the Apocalypse, instead turning against humanity along with the rest of angelkind. He became a master torturer/interrogator for Michael's army. In 2018, he was confronted by his counterpart, who killed him while Jack and the rest of the Winchesters saved Ketch and Apocalypse World's Charlie. Michael would later complain that this Castiel would never be as "anemic" as the Winchesters' Castiel.
• Jakob - A soldier in the human resistance, Jakob led a small group who were keeping their eyes on Michael's Fortress. He was killed when Kevin Tran used himself as a suicide bomb.
• Floyd - Floyd was making his way to Dayton alongside a group of humans to join the resistance. When attempting to pass through the Morehead Tunnel, the entire group was killed by a group of rabid vampires except for Floyd and Maggie. After meeting Sam, Dean, Castiel, and Gabriel, they all traveled through the Morehead Tunnel, but Floyd was killed when the group tries to fend off the vampires.
• Maggie - A survivor of a rabid vampire attack, Maggie traveled with Floyd, the Winchesters, Castiel, and Gabriel to make their way to Dayton. She is one of the many humans from Apocalypse World who make their way to the Winchesters' world. She was killed by Lucifer, but Jack gets him to revive her in exchange for exploring the universe together. She later becomes a hunter in the Winchesters' world. After Michael takes Rowena as a vessel, he smites Maggie.
• Ryan - A refugee from Apocalypse World and a close friend of Maggie's.
• Karen Singer - The wife of Bobby Singer and the counterpart to Karen Singer. Like the Karen who was the wife of the Bobby that the Winchesters knew, she also died under unnatural circumstances, driving her husband to hunting. Unlike her counterpart, she and Bobby had a son named Daniel who was also driven by her death to become a hunter.
• Daniel Singer - Bobby Singer's son in Apocalypse World who has no counterpart in the Winchesters' world. After the death of his mother, Daniel became a hunter alongside his father until the onset of the Apocalypse. Daniel fought in his father's platoon during the war, but was abducted and killed by the angels. His body was never found and his death continues to haunt his father.
• Jules - One of the many refugees who arrived from Apocalypse World. She and Castiel attempted to help Lora, who was suffering from an aging spell, but Jack ultimately discovered how the spell worked and neutralized it. She later assists the Winchesters with the Ghostpocalypse.
• Smithy - Among the Apocalypse World refugees, he appears to be their chef, making food for the other hunters. He was killed by one of Michael's rugarus during a monstrous incursion into the Bunker.
• Stevie - Among the Apocalypse World refugees, she helps defeat the Ghostpocalypse and later forms a romantic relationship with Charlie Bradbury after being introduced by Bobby Singer.

Episodes

12.23 All Along the Watchtower

After Jack inadvertently causes a rift in space and time, Castiel crosses over to investigate. Once through he finds himself on a dark and barren landscape, and is soon attacked by a tempter demon, which is shot and killed by that universe's Bobby Singer.

Bodies of demons, angels and humans strewn over the land.

When Sam and Dean learn about the rift they too, cross over with Castiel, where they meet with Bobby. Castiel and Bobby explain what happened in that universe -- Sam and Dean were never born on that world and thus never saved it from the Apocalypse. Soon after leaving, Sam, Dean, Castiel, and Crowley formulate a plan to trap Lucifer on the other side.

When Lucifer finally locates Kelly Kline's location, Sam and Dean lure him into the Apocalypse World, where Crowley has set up the ingredients for a ritual to close the rift, telling Sam he is missing only the final element: a sacrifice.

Lucifer tells Crowley that no matter what he tries, he will lose. Crowley turns to Sam and Dean and bids them a final "Bye, boys" before stabbing himself with an angel blade and completing the ritual.

Jack and Mary's group soon arrive at the old church, where Jakob finds Kevin Tran locked in the dungeon. Kevin pleads his innocence, telling the group he was forced into helping Michael, who promised to save humanity. After they find a map, with toy soldiers representing forces gathered to the south, Kevin reveals that Michael has found a place where the wall between worlds is thin and plans to cross over. He warns that Michael doesn't make mistakes and that he left the map for a purpose.

13.21 Beat the Devil

Arriving in Apocalypse World, Sam, Dean, Castiel, and Gabriel find themselves in Northern Kentucky, roughly two days away from their destination of Dayton, Ohio. As the group begins their two-day trek, they hear screams nearby. They rush over, much to Gabriel's protests, to find a feral vampire attacking two humans, Floyd and Maggie. Dean kills the vamp, and the two reveal to the group that when the angels began their extermination, they didn't consider what would happen to the monsters. With a smaller food supply, monsters like vampires devolved into a more feral state. Maggie tells them they were also en route to Dayton, having heard about Jack and Mary's satellite colony, but when attempting to cross through the Morehead tunnel, their group of nine came across a vampire nest, leaving only Floyd and Maggie as the survivors. With the Morehead tunnel the quickest route through to Dayton, Sam offers Maggie and Floyd protection through the tunnel.

Upon entering the tunnel, they quickly come across a vampire feeding off of the body of one of Floyd and Maggie's group, and it is swiftly decapitated by Sam. As they continue on, they find that their exit is blocked and have Castiel and Gabriel clear the path. As Gabriel and Castiel begin moving the rubble, the group is attacked by vampires. Sam and Dean do their best to fight them off, but Floyd is dragged away down a dark tunnel. As Dean saves Maggie from a vampire Sam has his throat ripped out and dragged away.

A feral vampire in Apocalypse World.

Finally arriving in Dayton, Gabriel shuts down the camp's warding sigils, allowing Castiel entry. The group is set upon by human resistance fighters and reunited with Mary and Jack, who learn of Sam's death. Back in the tunnels, Sam's dead body suddenly comes back to life thanks to Lucifer, who reveals to Sam he has consumed the grace of Michael's angels allowing him to bring Sam back and hold the nest of vampires at bay. He tells Sam he will strike a deal with him: in exchange for getting out of the tunnel, he wants to meet his son, Jack. Otherwise he will let the vampires attack Sam.

At the base camp, Dean prepares to leave to retrieve Sam's body as Jack admonishes Castiel and Gabriel for letting Sam die. Just as Dean is about to leave, he is shocked by the sudden arrival of a bloody but alive Sam, followed by Lucifer entering the camp.

13.22 Exodus

With the arrival of Sam and Lucifer to the camp, tensions quickly boil, causing Jack to teleport away from the fighting.

Sam and Dean reunite and go talk to Mary about finally leaving Apocalypse World, only for Mary to regretfully refuse their offer, telling her boys that she has been fighting with the refugees for nearly a year and can't abandon them. Sam, however, thinks of a compromise -- they take everyone back to their universe.

On the road to Bobby's salvage yard, the camp runs into a group of angels, but before they can smite anyone, Lucifer snaps his fingers and disintegrates them all, revealing to the group he only allowed them to restrain him for their own benefit as the handcuffs melt off his wrists.

At Bobby's salvage yard, the Winchesters put forth their plan to the leadership of the resistance who agree to put it to a vote. However, they then get news that Charlie Bradbury and Ketch have been captured by angels after falling into a trap. The angels torture the two for information on the resistance, but they refuse to break so the angels call in an expert torturer - the alternate Castiel. Before the torture can begin, Sam, Dean, Mary, Jack, and Castiel attack, rescuing the two and killing their captors. The alternate Castiel attempts to escape but is caught and killed by the Winchesters' Castiel after a confrontation.

After returning to Bobby's salvage yard, the Winchesters learn that the resistance has voted unanimously to evacuate through the portal to the Winchesters' world. Dean and Lucifer repair a bus to carry everyone and the evacuation begins with less than two hours to go. The Winchesters lead everyone to the portal just as it's on the verge of closing, but Rowena is able to hold it open using power from the Black Grimoire. The resistance travels through the portal with almost everyone making it through, including Jack and Mary, before Michael arrives to stop them, killing three resistance fighters with his arrival. Lucifer and Gabriel's attempts to stop Michael fail, resulting in the death of Gabriel. Before leaving, Sam purposefully strands the injured and weakened Lucifer in Apocalypse World again. Michael tries to follow Sam through the portal, but it closes before he can reach it.

Trivia

• Dialogue in 13.20 Unfinished Business suggests that the Apocalypse began in roughly 2010 in this world. In 14.02 Gods and Monsters, Bobby Singer comments that he has been fighting it for fifteen years, meaning since around 2003. However, this comment may also refer to Bobby trying to stop the events leading up to the Apocalypse.
