Gabriel

Gabriel is the last Archangel mentioned in the show. When his older brothers, Lucifer and Michael turned on each other and began fighting one another he couldn't bear it. Unable to choose sides he left Heaven and "took off" to Earth. After he gained a vessel, he went under "witness protection" and he began posing as a trickster, a Pagan god. It was later revealed in "Hammer of the Gods" that Gabriel made quite a name for himself and that among other Pagan gods, he was no ordinary trickster and that he was in fact the famous Norse god, Loki. Throughout the show he appears creating mischief for the Winchester brothers. According to Gabriel, "The Apocalypse" as humans call it was what he used to call "Sunday Dinner" between his family and says that The Apocalypse isn't even about the End of the World, but some massive feud between Michael and Lucifer who once loved each other but betrayed each other.

Season 2
He makes his first appearance in the episode "Tall Tales" as the Trickster, where he is the source of several violent urban legends coming to life and punishing those residing there. Sam and Dean investigate and eventually figure out his assumed identity. However, the trickster is waiting for them, and offers them a peaceful resolution so long as they let him leave to terrorize another town. Naturally, the Winchesters refuse and attack him, along with the help of Bobby. After fighting with various familiars conjured by the trickster, Dean manages to stab the latter while he is distracted, causing his creations to disappear and the fight to end. The Brothers assume the vanquished trickster was a copy, not knowing Angels are immortal nor knowing that he was Gabriel.

Season 3
Later reappears in "Mystery Spot". He traps Sam in a seemingly infinite time loop, where Dean continually dies in increasingly strange ways (once by Sam's own hand), with Sam continually failing to save him. After a countless number of repeats, Sam eventually realizes that a trickster must be at work, and manages to locate the culprit. He threatens their tormentor with a blood covered stake, causing the trickster to reveal himself and agree to break the loop. However, when Sam then considers killing him anyway, the trickster restarts the loop. Dean once again dies, but this time there is no loop to revive him. Throughout the next several months, Sam becomes a far colder and more calculating person as he attempts to track down the trickster, killing whatever threat he can along the way. Eventually, it is the trickster who calls the younger Winchester to him, where he tries to drive in a point: that the two brothers continually sacrificing themselves for one another would bring no good, and when people die, they just have to learn to accept it and live with it. Nonetheless, Sam pleads with him to turn back time so that he can save Dean. Reluctantly, the trickster agrees, lamenting that the whole situation had become boring months ago for him anyway.

Season 5
In "Changing Channels", the brothers investigate death of a man in Wellington, Ohio who apparently was killed by the Incredible Hulk. After the brothers learned that the man who died was well known for a having a bad temper and Sam found several candy wrappers at the crime scene, they deduce that the Trickster was responsible for the man's death. Realizing that the Trickster was one of the most powerful beings they ever met, Sam convinces Dean that they should ask for his help. Gabriel then sends a fake distress call to the brothers' police scanner to lure them to an abandoned warehouse. When the brothers enter the warehouse, Gabriel transports them into Dr. Sexy M.D., a television show that Dean watches. After the brothers are confronted by the show's main character, Dr. Sexy, Dean was able to figure out that he was the Trickster in disguise so Gabriel transforms back into his original form. Gabriel deduces that they came to ask for his help and clean up their mess. Sam asks for him to just hear them out, to which Gabriel agrees that if they survive "the game" for the next 24 hours then they can talk. Gabriel then teleports away, not answering Dean's question how what the rules to the game are.

Castiel attempts to get the brothers out of Gabriel's television world, but is teleported away from the Winchester brothers by Gabriel. The brothers eventually realize that "the game" is to play their roles. Castiel manages to escape from Gabriel and teleports to the brothers again. Castiel then tells the brothers that the Trickster is much more powerful than it should be and that Gabriel may not actually be a trickster. Before he can continue, Gabriel telekinetically throws Castiel into a wall and teleports him away. Dean then tells Gabriel that they get it and that "the game" is playing their roles. Gabriel corrects him and states that that's only half the game. He continues and says the other half is for the brothers to play their roles as the vessels of Michael and Lucifer. Sam tells Gabriel that if they say "Yes" then the world will end. Gabriel responds saying that's their fault and that they started the Apocalypse and there is no stopping it so they might as well get it over with. Dean asks Gabriel whose side he's on Heaven or Hell? Gabriel answers that he's on neither side and that he doesn't work for Michael or Lucifer. Dean doesn't believe him and tells him that he's bitch for one of them. Gabriel becomes angered and pins him against the wall and tells him to never presume what he is. He then the tells the brothers that they will accept the roles destiny has chosen for them or he will keep them in his television world forever.

Gabriel snaps his fingers and transports the brothers into a cop show. Dean stabs a man, who displayed traits of the Trickster, with blood covered wooden stake. A cop then begins to laugh and reveals himself to be Gabriel in disguise telling Dean he got the wrong one. Dean asks him, "Did we?" as Sam surprises Gabriel by stabbing him from behind with a wooden stake. It seems that Gabriel was killed as the television world disappears and the brothers are back in the real world.

The next day, the Winchester brothers realize the Trickster is not dead and they are still in his television world since Sam is in the Impala making it a talking car. Dean and Sam then yell out to Gabriel that they give up then Gabriel teleports in front of them. Dean refuses to say "Yes" until Sam is normal to which Gabriel complies and turns Sam human again with a snap of his fingers. Then brothers set fire to a circle of holy oil that Gabriel is in the middle of. Dean accuses Gabriel of being an angel due to the stake not working. Gabriel tries to deny this, but it's no use due to his inability to step outside of the circle so he teleports the three of them out of the television world.

Gabriel asks the brothers how they figured out. They explained what gave him away was how he easily overpowered Castiel and how he talked about Michael and Lucifer, Dean saying that no one gets that angry unless they're talking about their family. Sam then asks who he really is. The brothers are surprised when he reveals his true identity as the Archangel Gabriel. Gabriel explains to the brothers that he left Heaven and went into "witness protection" and became a trickster. He explains to Dean and Sam that he loves his brothers, but he couldn't take them fighting each other so he left. Sam then tells him to help them stop the Apocalypse, but Gabriel replies that it can't be stopped. He goes on saying that because of them he has to watch his brothers kill each other and he just wants the Apocalypse to be over with and couldn't care less whether Heaven or Hell wins. Gabriel continues saying that what humans call the Apocalypse was Sunday dinner for him with his family and that the Apocalypse isn't about a war but about two brothers who loved each other and betrayed each other. He then states that the brothers should be able to relate. The brothers are confused by this statement so Gabriel explains Michael, like Dean, is "the big brother" whose "loyal to an absent father" and Lucifer, like Sam, is "the little brother" whose "rebellious to daddy's plan".

Gabriel asks the brothers if they ever wondered why he was so interested in them. He answers that it was because the brothers were born to be the vessels of Michael and Lucifer and that all the angels knew that they going to fight and that one will kill the other. Dean says that that won't happen, but Gabriel apologizes and says it will. Dean tells Gabriel to bring Castiel back threatening to kill him by pouring holy oil on him and setting him on fire. Gabriel complies and brings Castiel back with a snap of his fingers. Castiel says hello to Gabriel revealing that he figured out his identity. Gabriel greets his brother and sarcastically asks him how the search for Dad is going. The three begin to leave and Gabriel asks if they plan on leaving him trapped forever. Dean turns around and says no because they don't screw with people the way he does. Dean goes on and says the Apocalypse isn't about a ultimate match between his brothers or a destiny that can't be stopped, it's about him being to afraid to stand up to his family. Dean then hits the warehouse's fire alarm activating the sprinkler system extinguishing the burning holy oil. The three then leave Gabriel.

In "Hammer of the Gods", Gabriel comes to save Dean and Sam after they are captured by a group of Pagan gods. Before Dean and Sam say his name, Gabriel uses his powers to take away their voices. The Norse god, Baldur, asks Gabriel, who he knows as the Norse god Loki, why he's here. Gabriel answers he's come to talk about the Apocalypse and how they can't stop it. Before he goes on, he teleports Dean and Sam back to their room telling them that the "adults" need to talk.

Shortly Gabriel joins the brothers interrupting their planning on what to do about the situation. Dean immediately accuses Gabriel of being behind the predicament that he and Sam are in. Gabriel corrects him and states that he's here to save them. He explains that the Pagan gods are either going to use the brothers as bait or kill them. Dean notes how ironic it is that a couple of months before Gabriel was trying to force he and Sam to "play their roles". Gabriel replies saying that Michael and Lucifer are still going to fight just not tonight and not here. Dean then asks Gabriel, why he cares. Gabriel reveals to the brothers that he and Kali, the Hindu goddess, had a "thing". Sam asks Gabriel if the Pagan gods have a chance against Lucifer wondering if this was Dean and his best chance to kill him. Gabriel tells him that they stand no chance against him and that Lucifer's "gonna turn them into finger-paint". Gabriel then explains that he can't teleport the brothers out since Kali has their blood and performed a blood spell, which essentially puts them on a leash. But, Gabriel plans on seducing her and getting their blood. Dean then tells Gabriel that they have to save the other guests and employees that the Pagan gods plan on feeding on as well. But Gabriel tells Dean to forget them since it'll be hard enough to break him and Sam out. But Dean remembering that the other gods referred to him as Loki, threatened to expose Gabriel's true identity to them if he doesn't help the others. Gabriel having no choice reluctantly agrees.

Gabriel then teleports to Kali and trying to retrieve the blood of the Winchester brothers. He attempts to seduce her but he is quickly turned down by her. It is then revealed that Kali was the one who invited him to the gathering of the Pagan gods, hoping that he would take the situation seriously. He tells Kali that is taking this seriously and tells her that if she and the other Pagan gods fight they will die. Kali asks how he's such an expert. He tells her that he's tangled with angels before. He then begs her not to fight, but Kali says that she has to. Gabriel responds saying that he had to try and asks Kali if she still loves him. Kali says no, but then pulls him in to kiss him. As they kiss, Gabriel attempts to take the brothers' blood, but is interrupted when Kali scratches him and takes some of his blood. She reveals to him that she knows that he is the Archangel Gabriel and now that she has his blood he is bound to her forever.

Gabriel is then taken to the meeting room and soon joined by the captured Winchester brothers. Kali then takes Gabriel's archangel blade. Kali accuses of him of being a spy, but he corrects her and says that he is a "run-away". He then says that even though he lied about his identity, that doesn't mean he's wrong about them losing to Lucifer. He tells her and the other gods that he's "skipped ahead" and seen how this ends. Kali then lectures him about how arrogant angels are for thinking that they can just "rip the planet apart" and how his Father isn't the only god. She then says that they were here first and if anyone is going to destroy the world, it's her. Kali apologizes and then stabs Gabriel with his own blade, killing him.

After Dean makes a truce with the Pagan gods and escorts the captured employees and quests out of the hotel, he finds that Gabriel is alive and hiding in the Impala. Gabriel tells him that the sword was a fake and that he made it from a can of soda. Gabriel then tells Dean to grab their blood because Kali seems to like him meaning he can get close to her then once he does he'll be able to teleport him and Sam out. Dean refuses and asks for Gabriel's real archangel blade then tells Gabriel that he should actually help them kill Lucifer. Gabriel asks Dean if he's serious, unable to believe that he would team up with a bunch of "monsters". Dean replies saying this is the best idea he has for taking out Lucifer. Gabriel sarcastically tells Dean good luck and that he's leaving and that it's not his problem if the Pagan gods want to commit suicide. Dean tells Gabriel that he knows he's lying and that he does actually care about the Pagan gods like they were his actual family. Gabriel tells Dean that he can't kill his own brother to which Dean asks him, "Can't or won't?" before he leaves.

Later, after Lucifer has killed all the Pagan gods except Kali, Gabriel teleports next to the Winchester brothers who are taking cover while Lucifer and Kali fight. Gabriel hands Dean something telling him to guard it with his life. He then uses his telekinesis to throw Lucifer stopping him from killing Kali. He tells Dean and Sam to get Kali out of here, leaving him to take on Lucifer alone. Lucifer can't believe Gabriel is doing this over a girl, especially a disgusting Pagan goddess. Gabriel tells Lucifer that he is his brother and that he still loves him. But then he lectures Lucifer how he can play victim all he wants, but they both know that "Dad" loved him best over himself and Michael. Gabriel goes on saying when God created humanity he couldn't handle it and he went on a temper tantrum and now it was time for him to grow up. Lucifer originally believes that Gabriel is doing this for Michael, but Gabriel states that if Michael were here he would stab him too. Lucifer then insults him calling him disloyal, but Gabriel states that he is loyal, not to the Pagan gods but humanity. He then tells Lucifer that their Dad was right and that humans are better than angels, they maybe flawed but they try to do better and forgive. Lucifer asks his brother to not make him kill him. Gabriel tells Lucifer that no one makes them do anything. Gabriel tries to kill Lucifer by having him talk to a copy while the real Gabriel is behind Lucifer. Gabriel attempts to stab Lucifer with his archangel blade, but Lucifer turns around and stabs his brother with his own blade. The copy disappears and Lucifer calls it "amateur hocus-pocus" reminding his little brother that he learned all his tricks from him. Gabriel then dies with his older brother looking down on his corpse crying.

Later, Dean and Sam view what Gabriel gave Dean before they left. It at first seems like a regular pornographic video, but then they see Gabriel is in the video. In the video, Gabriel explains that if the brothers are watching this that means that he died and failed to kill Lucifer. Gabriel goes on to say that he was their only shot at killing Lucifer, but the brothers can still trap him. He explains that the cage that they freed Lucifer from is still there and that can use it to trap him. Gabriel then explains that the cage has four keys and that not even Lucifer knows this but the keys are the rings of the four horsemen. Gabriel then tells Dean that he was right and that he was afraid to stand up to his brother. The brothers then stop the video.

Powers
As an Archangel of the Lord, Gabriel has many supernatural abilities. He appears to be able to teleport himself and others. He is immune to almost every known way of killing the supernatural. Each Archangel's powers would be unique to them as all archangels are patrons of certain things (e.g Raphael: doctors, Michael: soldiers, etc), and the higher ranking archangels like Michael would be more powerful. Also like demons, angels appear to have telekinetic capabilities. Angels are immune to all human diseases.
