What you brought to His Earth, all the mayhem, the murder. Just the raw, wild invention of God's naked apes -- it was mind-blowing. But really it was your storytelling. That is the true flower of free will. At least as you've mastered it so far. When you create stories, you become gods, of tiny, intricate dimensions unto themselves. So many worlds! I have read as much as it's possible for an angel to read, and I haven't caught up.

Metatron is an angel and the scribe who recorded the Word of God on a series of tablets. God, having decided to leave Heaven, chose him to write down instructions related to his creations. After he left, the archangels began to plot to take over the universe themselves. Realizing that they needed the tablets and him, Metatron also left Heaven, fleeing to Earth where he lived amongst a Native American tribe. In return for them telling him stories, he gave them longevity. Metatron has been entirely cut off from Heaven, with no knowledge of the Apocalypse or surrounding events. He spent all his time reading in Colorado. After finding out what's going on from Sam and Dean, Metatron uses Castiel to get the ingredients for a spell to cast all the angels down from Heaven. He succeeds, turning Castiel human and killing Naomi along the way. Metatron eventually works on rebuilding Heaven under his rule, using Gadreel to do his dirty work and recruit angels while Metatron uses the angel tablet to gain God-like powers. After succeeding in uniting the angels under his control using brainwashed suicide bombers, Metatron turned his attention to humanity but Sam, Dean, Castiel, Gadreel and later Hannah worked together to stop him. Although he succeeded in killing Dean who tried to fight him with the First Blade, Castiel shattered the angel tablet and tricked Metatron into broadcasting his true intentions on angel radio, causing his own followers to turn on him and imprison him in Heaven's dungeon on Castiel's orders rather than kill him. Metatron's cell door was then made permanent and he was put in a straight-jacket to keep him locked up. Metatron has now vowed to one day escape and get his revenge. He was briefly taken to Earth to help remove the Mark of Cain from Dean, but after Dean nearly killed him, he was returned to his prison in Heaven. Castiel and Bobby Singer later broke him out in an attempt to once more learn information from him. In order to have leverage over him, Castiel removed Metatron's grace, rendering him human and vulnerable. Metatron admitted that he knew of no cure to the Mark and had been lying before, but promised to give Castiel the rest of his grace in exchange for his life. However, this turned out to be a trick so Metatron could escape with the demon tablet and Castiel's grace which he'd stored in the same place. While Metatron succeeded in getting away with the demon tablet, Castiel was able to get his grace and full power back though he and Sam worried about what Metatron could do with the tablet and his freedom. Following his escape, Metatron became a videographer, seeing himself as the "author of reality" through his new job. However, Metatron hated his existence as a human and wanted to die. After Castiel tracked him down, he retrieved the demon tablet and nearly beat Metatron to death due to his taunts. He stopped himself and got Metatron to tell him what he knows of the Darkness. Afterwards, seeing Metatron as no threat as a human and without the demon tablet, calling him "pitiable" now instead, Castiel let him go, knowing the angels would destroy Metatron if he did anything to draw attention to himself.
Metatron possesses a short, middle-aged man with black hair.

Metatron. He's an angel; he's the scribe of God. He took down dictation when creation was being formed.
Metatron is briefly mentioned by Castiel while examining a stone tablet containing the Word of God; he notes that Metatron is an angel who kept records of Creation. Dean believes that the angel may be able to help them against the Leviathans, but this is the last they speak of him.
Metatron is mentioned again by Kevin Tran, a prophet, whilst reading the Word of God tablet dedicated to demons. He says that Metatron left a "personal note" on the tablet which reads as a farewell and apology to God for choosing to leave this world. It also reveals that there are more tablets than just the ones about leviathans and demons, which are "for the defense of mankind." The note wrongly lists Metatron as an archangel.
- "I'm not one of them. I'm not an archangel. Really more run-of-the-mill. I worked in the secretarial pool before God chose me to take down the Word. Anyway, he... seemed very worried about his work, what would happen to it when he left, so he had me write down instructions. Then, he was gone. After that, the archangels took over. And they cried, and they wailed. They wanted their father back. I mean, we all did. But then... then they started to scheme. The archangels decided if they couldn't have Dad, they'd take over the universe themselves. But they couldn't do anything that big without the Word of God. So I began to realize, maybe they would realize... they needed me."
While reading Kevin's notes from his translation work on the demon tablet, Sam notices a recurring symbol which appears to be Metatron's signature. It is familiar to him from a course he took at Stanford on Native American art. Its a petroglyph from a tribe in Colorado called the Two Rivers. As the tribe is supposed to be protected by the Messenger of God, Sam and Dean realize this is where they might find Metatron and head to have a look.
As they check into a hotel, Sam becomes more unwell, hearing noises, developing a fever, and having vivid memory flashbacks to his childhood. They find Metatron in a hotel room, surrounded by thousands of books. He is unaware of any of the events related to Heaven, or Lucifer and the Apocalypse and hasn't even heard of the Winchesters. He explains that he left Heaven to protect the tablets and himself from the archangels who want to use them to take over the universe. Metatron further explains that as Sam has passed two of the trials, he is starting to resonate with the tablets, and with Metatron, allowing him to sense both when he is in close proximity. Sam and Dean are angry at him for ignoring all the suffering wrought by Heaven and the angels and tell him about Kevin Tran who they believe is dead as a result.
Metatron decides to catch up on current events and as a result, decides to get involved. Even though Crowley has angel-warding protecting where he is keeping Kevin, as the Scribe of God, Metatron is able to simply erase it and he rescues Kevin as Crowley is strangling him to death. Metatron's rescue of Kevin leaves Crowley burned. Returning to the hotel, Metatron heals Kevin and talks to Dean about what happens next. He is willing to join them now, but suggests that perhaps closing the Gates of Hell might not be a good idea, asking Dean what he is willing to do to achieve it and to consider what will happen when the gates are closed. Kevin wakes up and reveals he has the second half of the demon tablet and the third trial and before Kevin can reveal it, Metatron does: Sam must cure a demon. Kevin confirms it and asks who Metatron is.
- "Oh, you know, the trials -- God's little "pull in case of emergency." The Leviathans get out of control, you put them in Purgatory. Demons get a little too demonic, toss 'em into Hell. Angels get uppity, slam the pearly gates."
Metatron approaches Castiel to talk about the situation in Heaven. He's done some investigating and found many factions all at war trying to gain control -Naomi leads just one of them. Castiel feels responsible after all the destruction he wrought in Heaven. Metatron invites Castiel to join him for some crepes at a restaurant. He tells Castiel that he thinks they should close Heaven off from Earth - to force the angels to sort out their issues, and also to prevent any of their conflict from causing damage on Earth. He says that the angel tablet contains trials which when completed will close Heaven. As the Scribe of God, Metatron knows them without the tablet. Metatron says he's just a writer, but that Castiel is a warrior.
Castiel agrees to undertake the trials - even though Metatron warns that they will be more difficult than Cas can imagine. He then points out Jane, the young woman who has been their waitress. Metatron reveals the first trial is to kill her and cut out her heart becasue she is Nephilim and considered an abomination. That night, the two angels trail her to kill her, but she reveals her knowledge of what they are and begs them not to kill her. As she is an innocent woman, Castiel hesitates, but when she attacks him and Metatron, Castiel kills her with his angel blade while she attacks Metatron and completes the first trial.
- "God? Mm, pretty much like you'd expect. Larger-than-life, gruff, bit of a sexist. But fair -- eminently fair."
Metatron tells Castiel that the second trial is to obtain the bow of a Cupid. Metatron has ascertained that Dwight Charles - a bar tender - will be shot by a Cupid's arrow. He and Metatron start watching Dwight, but Naomi arrives and abducts Metatron.
As Naomi prepares to interrogate Metatron, he reveals the depth of his hatred for the angels. He describes how special he felt as God's scribe, and how bereft after God left. Then knowing the archangels would try and extract all of God's secrets from him, he fled Heaven. Now, he tells her, he wants revenge.
Castiel turns to Dean for help. When they see a delivery woman arrive at the bar, they think she will be the one that Dwight falls in love with. However she is the Cupid, and she causes Dwight and his regular customer Rod to fall in love. Outside the bar, Dean and Castiel tell the Cupid they need her bow, which appears as a mark on her hand. She tells them how chaotic Heaven is, and willingly helps them.
Back at the Bunker, Kevin has been examining the angel tablet, and calls Dean to tell him he cannot find any mention of the trials Castiel has undertaken. Just then Naomi arrives and having interrogated Metatron, she tells Dean and Castiel that Metatron's plan is to close Heaven - but also to expel all the angels. When she returns to Heaven, Metatron kills her with her own torture implement, having escaped in Naomi's absence.
When Castiel finds Metatron, he extracts Castiel's grace from him, telling him its the final part of a spell that will achieve what Naomi described. He sends Cas back to Earth, and completes the spell, causing all the angels to fall to Earth.
Its revealed that at least most of the angels are angry at Castiel for his role in Metatron's plot and want revenge on him.
As a result of Castiel's role in Metatron's plot, the angels are actively hunting him down. After capturing Castiel, a rogue reaper possessing April Kelly who is working for Bartholomew tortures him for information on Metatron's spell and how to reverse it. Castiel explains that he had no idea what Metatron intended and only knows that his grace was the final ingredient but suggests that as his grace was the key to Metatron's spell working, he himself might be the key to reversing it.
Kevin finds a reference to fallen angels in the footnotes of the angel tablet and realizes that its possible that Metatron may have written about the spell in the tablet's footnotes. Kevin is able to translate the tablet into Elamite cuneiform and he and Sam bring it to Crowley for translation. After completing a deal with the two, Crowley translates it to learn that the spell is in fact there, but that Metatron made it irreversible.
- "Rebuild Heaven as the place God envisioned it, only with a handpicked few. No more anemic functionaries like Bartholomew. And no more stupid angels... Maybe some funny ones."
Metatron speaks to the angel in Sam's body, revealing that he knows the angel possessing Sam is not Ezekiel, but Gadreel. Metatron tells Gadreel he plans to rebuild Heaven and restore it to its former glory. He invites Gadreel to be his second in command, and restore his besmirched name. Gadreel agrees, but Metatron demands a demonstration of his loyalty. He wants those who could oppose him killed, and gives Gadreel a piece of paper with the first target. Gadreel takes on the challenge - and kills Kevin Tran.
- "Not much for seizing the initiative, are we?"
Metatron continues to give Gadreel names of people to kill. Metatron has also "flipped a switch" in Heaven to prevent the continuation of Prophets after Kevin's death. Metatron also gave him that name of an angel who had abused Gadreel in prison. While at a bar, ironically with Gadreel's first vessel as the bartender, Gadreel arrives to give Metatron the tablets and is getting sick of killng humans and angels but Metatron gives him another which turns out to be a cellmate of Gadreel's in Heaven who he reluctantly kills. Metatron also tells Gadreel that his place isn't to question but to obey. Later Metatron is waiting at the bar again to a status update when Gadreel does not contact him. Gadreel does eventually arrive but in his angelic form and possesses his first vessel again. Metatron instantly assumes the Winchesters have set him back.
Bartholomew reveals to Castiel that he has been racing against Malachi to find Metatron, having successfully tracked him on Earth on three occasions in Washington, Michigan and Georgia through a massive ground operation.
- "What makes a story work? Is it the plot, the characters, the text? The subtext? And who gives a story meaning? Is it the writer? Or you? Tonight, I thought I would tell you a little story and let you decide."
Metatron has holed himself in a room with a typewriter, surrounded by Chuck's novels. He captures Castiel, bringing him to him under the illusion of a fictional scenario he created. In the illusion, the archangel Gabriel has returned to life to try and convince Castiel to lead the angels against Metatron. After Castiel breaks free from the illusion, Metatron tells him that he wants him to be the villain in his own story in which Metatron is the hero. Metatron then hears about his right hand man, Gadreel, being taken hostage by the Winchesters. Metatron proposes a trade, Castiel for Gadreel. When he arrives at the meeting place, he lets himself fall into a holy fire trap set by Sam and Dean to show that he cant get out of it, which he does. He then honors their deal but reminds them that no matter what they come up with, they can't win against him. Later, Metatron gets back to work and speaks to Gadreel who asks him if the Winchesters capturing him was part of Metatron's plan. Metatron explains that in a story, sometimes characters do surprising things but as long as he knows the ending, what happens on the journey is of little importance.
- "Well, that's an old writer's trick -- flipping the script. You start by building up a seemingly unbeatable enemy, like the death star, or a rival angel with a bigger army. That way, I look like the underdog. But then, oh, no! The competition gets greedy. He starts pushing things too much. With the help of my combustible double agents. And then, after a rousing speech, his true weakness is revealed. He's in love with humanity. And now... I'm inevitable."
Metatron tries on a trench coat similar to Castiel's and then meets with angelic faction leader Tyrus. Tyrus refuses to listen to Metatron's offer and points out that if Gadreel kills him, his faction will just join Castiel. He challenges Metatron to a round of bowling to see if he'll listen to the offer, but Metatron loses. As Metatron and Gadreel are leaving, Constantine arrives and blows himself up, killing Tyrus and injuring Gadreel. Metatron then contacts Castiel's faction and offers them all amnesty if they switch sides immediately, telling them about Castiel's fading grace and that he only cares about Sam and Dean. Metatron is pleased when Castiel's angels join him, revealing to a disgusted Gadreel that it was his plan all along and he planted the suicide bombers to draw all angels to his side. However, Gadreel is so disgusted by Metatron's actions, he switches sides.
- "Do you have any idea how much pan-cake makeup and soft lighting it took to get God to work a rope line? He hated it. And, you know, humans sense that. So they prayed harder and longer and fought more wars in his name. And for what?! So they could die of Malaria? Leukemia? And all the while, blaming themselves! 'Oh, if only I'd been more prayerful, God would have loved me! God would have saved me!' You know what?! God didn't even know their name! But I do. Because I've walked among them. And I can save them."
Metatron makes a broadcast to all the angels across "angel radio" stating that he is going to Earth and the portal to Heaven will be closed until his return. Metatron, taking on a scruffy homeless appearance, resurrects a young woman hit by a truck and heals a homeless man of his diabetes, earning him human followers who look to him as their new savior. When an angel reveals the truth, Metatron nearly attacks him until his new followers do it for him and kill the angel with Metatron's angel blade. That night, Dean arrives and faces against Metatron with the First Blade. Metatron is amused since the angel tablet grants him great powers and he knows that Castiel and Gadreel are failing in their mission to break his link to it. Metatron easily overpowers Dean and stabs him with his sword, mortally wounding him. At the same time, Castiel shatters the tablet, breaking Metatron's connection to it and removing his added powers. Metatron quickly flees when Sam swings an angel blade at him. Metatron goes to Heaven where he traps Castiel in a chair and taunts him about Dean's death and how the angels are just "sheep" who will follow Metatron wherever he leads them no matter what he's done to bring them under him and speaks down on humanity. As Metatron goes to kill Castiel, Castiel reveals that he broadcasted the whole conversation over "angel radio" and the angels storm the office and overpower Metatron. Rather than killing him for his actions, Castiel locks Metatron in Heaven's dungeon.
- "Well... Everybody wants something. Question is, are you willing to pay for it? Are you willing to... I don't know -- let me out? Oh, come on. don't look so shocked. You knew what I'd ask for. And you wouldn't have come here if you weren't willing to pony up."
Hannah pays a visit to Metatron's prison cell, wanting to know if there was any of Castiel's grace left after he did the spell to expel all angels from Heaven. Metatron tells her there is a little bit left, and promises to give it to her, if she lets him out -- claiming that he has grown sick of Earth and will seek out a new planet in a new galaxy if he is set free. As Hannah contemplates the deal, Castiel shows up and refuses; telling Metatron that he has come to accept his own fate, and that the thought of him rotting in a prison cell until the end time is solace enough. But before Castiel leaves Metatron threatens that one day he will be free, whether it is a century or a few millenniums, and when he is free he will kill everyone.
- "Ah. Well, information does happen to be a specialty. Got about two billion fun facts up here. Of course, whether I choose to cough one up or not is another matter."
Needing information on how to remove the Mark of Cain and with the demon tablet missing, Castiel has Ingrid bring Metatron to Earth to be questioned on how to remove it. Metatron is taken to the Men of Letters Bunker where he is questioned by Sam and Dean for information. Metatron eventually reveals that there is a way, but they need the First Blade to do it.
After Crowley refuses to give up the Blade until a way is discovered to remove the Mark, Dean goes to Metatron for the rest of the spell. However, Metatron reveals that with each tidbit of information he gives, he wants something in return and there will be a lot of that. Metatron taunts Dean into giving into the Mark's power, stating that each time he does, he falls further under its influence, resulting in Dean severely beating him. Eventually Dean turns an angel blade on Metatron and starts cutting him, seriously wounding Metatron. Before Dean can kill Metatron, Sam and Castiel break in and restrain him. Rather than risk Metatron's life further, Castiel takes him back to Heaven with Metatron telling them that next time he will choose death over helping. However, while ranting at Dean, Metatron leaves one possible clue that Dean mulls over: "the river ends at the source."
- "No, no! No! Your Grace! I wasn't lying about that. There's still some left. I'll take you to it."
As Dean gets worse, Sam gets desperate enough to try to get information from Metatron once again. Castiel reluctantly agrees to help, but Hannah refuses to let him take Metatron as he'd want his freedom in exchange for information and is too dangerous to be let free. With help from Bobby Singer, Castiel breaks Metatron out and takes him to Earth where he removes his grace with an angel blade. Now human, Metatron is left vulnerable and Sam shoots him in the leg to make a point. When Castiel threatens his life, Metatron finally breaks down and admits he knows of no cure to the Mark of Cain and was making things up before to buy himself some time until he could screw them over. While Sam doesn't believe him, Castiel is able to tell that Metatron is telling the truth. As he is no longer useful, Sam goes to kill him, but Metatron desperately reveals that he wasn't lying about there being some of Castiel's grace left and offers it in exchange for his life. Castiel reluctantly agrees and puts Metatron in his car to find it.
- "How many more rogue angels are there out there? And, what are you gonna do once you’re done with all that? Go back to Heaven? Please. The angel formerly known as Hannah has restored order up top. Smoothest it’s run since God cut the ribbon on the pearly gates."
Continuing on their road trip to the location of Castiel's grace, Metatron is ruminating on his new found humanity like his new found enjoyment of music and food -- much to Castiel annoyance, which is compounded with the fact that each of the safe houses Metatron has lead them to did not contain Castiel's grace. After stopping at a diner so Metatron can eat, the two come across a cupid who believes that the two of them have corrupted Heaven and attempts to kill them for it. Metatron attempts to run away, but his leg wound causes him to fall. Vulnerable, the cupid advances on him, but Castiel is able to tackle him to the ground. In the ensuing tussle, the cupid gets the upper hand, and is about to deliver a killing blow to Castiel when Metatron saves Castiel by stabbing the cupid in the back, killing him.
Soon after the fight, Metatron takes Castiel to a library, and find a clue to the location of Castiel's grace. As the two of them search the books in the library, Metatron demands to know the truth about what Castiel thinks he is going to do once he gets his grace back and there are no more rouge angels on the Earth for him to capture. When Castiel has no answer for him, Metatron uses his blood to draw an Enochian spell which incapacitates Castiel, allowing Metatron to get what he came for -- the demon tablet. When Castiel realizes that the riddles are quotes from books, and quickly surmises that his grace is in a copy of Don Quixote. However, Castiel is able to reach the book before Metatron, much to Metatron's dismay, and regain his grace. As Castiel takes in his grace, Metatron makes a hasty escape with the demon tablet in tow.
Efram and Jonah interrogate Castiel for information on Metatron's whereabouts, not believing that Metatron tricked him and escaped despite it being the truth. They even try to hack his brain for the information they want leading to a scuffle that leaves the two angels and Hannah dead.
Believing that Metatron may know something about the Darkness and how to stop her, the Winchesters and Castiel search for clues to his location, trying to find him through Castiel's car which he had stolen to escape. However, there's no sign of Metatron having an accident or even getting a ticket which Castiel finds surprising as he didn't believe Metatron, as a former angel and shut-in, would be a good driver.
- "Hey! Do you have any idea how much stuff I had to steal and then pawn to pay for that?!"
While watching a news clip of a violent crime, Castiel spots that the videographer is Metatron from his reflection in a car's mirror.
Metatron films the aftermath of a shooting, stealing the man's wallet and money only to discover that he is still alive. Metatron bemoans how he used to be able to heal such wounds with ease, though he can't anymore and wouldn't anyway. As Metatron tells the man that he's "not that guy" anymore and can't save him, Castiel appears behind him and tells Metatron that he can save the guy. Castiel heals the man's wound as Metatron video tapes, explaining that he found Metatron the same way he finds his crimes, by scanning the police radio and then getting to the scene of the crime before the cops. Seeing Metatron recording him, Castiel knocks the camera out of his hand and breaks it, to Metatron's annoyance. As a police car arrives, Castiel grabs Metatron and drags him away.
Castiel takes Metatron to an old warehouse where he is disgusted by what Metatron is doing for money. Metatron points out that Castiel only tried to live as a human for around a month but Metatron is human forever, he tells Castiel that he was nothing when Castiel took his grace, on the run from angels without money but he managed to build his own business. Metatron claims that religion and literature are dead so he has caught up with the times, telling him that reality is the new literature of the era and he's out on the streets every night capturing it, seeing himself as reality's author. An annoyed Castiel starts to ask Metatron about the Darkness, but Metatron misunderstands what he wants and believes he wants the demon tablet. Metatron tries to claim that he hid it where Castiel and the Winchesters will never find it, but Castiel pulls the demon tablet out of his coat and tells Metatron he found it under his mattress after searching his apartment. Castiel once again asks Metatron about the Darkness, but while Metatron admits he knows something, he refuses to tell Castiel. When Castiel threatens him, Metatron calls him broken, scarred deep and paralyzed by trauma and fear. Telling Metatron its not fear, Castiel attacks Metatron, beating him badly and demanding answers about the Darkness. Metatron simply continues to taunt Castiel about how everyone uses him enraging Castiel into further attacking and leaving Metatron badly beaten. Castiel nearly beats Metatron to death, but when Metatron asks Castiel to finish the job, he stops himself. Castiel realizes Metatron wants to die and asks him about what he said about being happy as a human and building a life for himself. Metatron admits he lied and can't stand a human life anymore. Castiel refuses to kill Metatron, telling him that Metatron was right about Castiel being tired of having his strings pulled and he won't let the former angel off easy. Castiel asks Metatron again about the Darkness and Metatron reveals the truth about it: the Darkness is God's sister that he had to give up in order to create the world.
After getting what he needs from Metatron, Castiel lets him go to the Winchesters' annoyance. Castiel explains that Metatron isn't going anywhere as if he draws any sort of attention, the angels will destroy him. Castiel tells the Winchesters that Metatron is now human "and a pitiable one at that" and that he left him in traction.
Metatron in Lore
Metatron is an archangel in Judaism. He is considered the highest of the angels, and serves as the celestial scribe. Mentioned briefly in the Talmud, he appears primarily in medieval Jewish mystical text. In the Zohar, he is identified as the angel that led the people of Israel through the wilderness after their exodus from Egypt.
