Early life Loki was born a Frost Giant and abandoned as an infant by his father
Laufey, only to be found by
Odin during an invasion of the realm of the Frost Giants in
Jotunheim. Odin used magic to change Loki to look like an Asgardian and raised him as a son alongside Odin's biological son,
Thor. During his upbringing, Odin's wife
Frigga taught Loki how to use his magic. He used these powers throughout his life, constantly tricking his adoptive brother Thor, as well as pulling a heist on Earth under the alias
D. B. Cooper. He was embittered throughout his upbringing, perceiving that he was neglected by Odin in favor of Thor, and thus grew closer to his adoptive mother Frigga instead.
Betrayal of Asgard Hundreds of years later, in 2011, Loki watches as Thor prepares to ascend to the throne of
Asgard. This is interrupted by Frost Giants, allowed in to Asgard by Loki, attempting to retrieve an artifact called the Casket, which was captured by Odin in a war centuries before. Loki then manipulates Thor into traveling to Jotunheim against Odin's order to confront Laufey, the Frost Giant leader. A battle ensues until Odin intervenes to save the Asgardians, destroying the fragile truce between the two races. Loki discovers that he is Laufey's biological son, adopted by Odin after the war ended. After Odin exiles Thor to Earth, Loki confronts Odin about his parentage, and a weary Odin falls into the deep "Odinsleep" to recover his strength. Loki takes the throne in Odin's stead and offers Laufey the chance to kill Odin and retrieve the Casket.
Sif and the
Warriors Three, unhappy with Loki, attempt to return Thor from exile, convincing
Heimdall, gatekeeper of the
Bifröst—the means of traveling between worlds—to allow them passage to Earth. Aware of their plan, Loki sends the
Destroyer, a seemingly indestructible
automaton, to pursue them and kill Thor. The Destroyer leaves Thor on the verge of death but his sacrifice sees him become worthy of returning from exile and he regains his powers and defeats the Destroyer. Afterward, Thor leaves with his fellow Asgardians to confront Loki. In Asgard, Loki betrays and kills Laufey, revealing his true plan to use Laufey's attempt on Odin's life as an excuse to destroy Jotunheim with the Bifröst, thus proving himself worthy to Odin. Thor arrives and fights Loki before destroying the Bifröst to stop Loki's plan, stranding himself in Asgard. Odin awakens and prevents the brothers from falling into the abyss created in the wake of the bridge's destruction, but after Odin rejects Loki's pleas for approval, Loki allows himself to fall into the abyss. In space, Loki encounters the Other, the leader of an extraterrestrial race known as the
Chitauri. In exchange for retrieving the
Tesseract, a powerful energy source of unknown potential, the Other promises Loki an army with which he can subjugate Earth. Later,
Erik Selvig is taken to a S.H.I.E.L.D. facility, where
Nick Fury opens a briefcase and asks him to study a mysterious cube. Loki, invisible, prompts Selvig to agree, and he does.
Invasion of New York In 2012, Loki attacks a remote
S.H.I.E.L.D. research facility, using a
scepter that controls people's minds and which, unknown to him, amplifies his hatred for Thor and the inhabitants of Earth. He uses the scepter to brainwash
Clint Barton and Dr.
Erik Selvig, and steals the Tesseract. In
Stuttgart, Barton steals
iridium needed to stabilize the Tesseract's power while Loki causes a distraction, leading to a brief confrontation with
Steve Rogers,
Tony Stark, and
Natasha Romanoff that ends with Loki allowing himself to get captured. While Loki is being escorted to S.H.I.E.L.D. on the
Quinjet, Thor arrives and takes him away, hoping to convince him to abandon his plan. Thor eventually takes Loki to S.H.I.E.L.D.'s flying aircraft carrier, the
Helicarrier. Upon arrival, Loki is imprisoned while
Bruce Banner and Stark attempt to locate the Tesseract. Agents possessed by Loki attack the Helicarrier, disabling one of its engines in flight and causing Banner to transform into the Hulk. Thor attempts to stop the Hulk's rampage, and Loki kills the agent
Phil Coulson and ejects Thor from the Helicarrier as he escapes. Loki uses the Tesseract, in conjunction with a device Selvig built, to open a wormhole above
Stark Tower in
New York City to the Chitauri fleet in space, launching his invasion. The
Avengers arrive and rally in defense of the city. As the Chitauri are ultimately defeated, the Hulk attacks Loki and beats him into submission in the Tower, before Loki is arrested and taken to Asgard.
Battle with the Dark Elves In 2013,
Dark Elves led by
Malekith attack Asgard, searching for
Jane Foster, whose body has been invaded by an unearthly force known as the Aether. Malekith and his monstrous lieutenant
Kurse kill Loki's adoptive mother
Frigga, who had taught Loki magic. Thor reluctantly frees Loki, who agrees to take Thor to a secret portal to
Svartalfheim, home of the dark elves, in return for Thor's promise to take vengeance for their mother. In Svartalfheim, Loki appears to betray Thor, in fact tricking Malekith into drawing the Aether out of Jane, but Thor's attempt to destroy the exposed substance fails. Malekith merges with the Aether and leaves in his ship as Loki appears to be fatally wounded saving Thor from Kurse, whom Loki was able to kill through trickery. Thor ultimately defeats Malekith in a battle in
Greenwich, and returns to Asgard to decline Odin's offer to take the throne, and tells Odin of Loki's sacrifice. After Thor leaves, it is shown that Loki has actually survived and taken Odin's place on the throne, disguised as Odin, having kept the real Odin under a spell on Earth. During this time, the disguised Loki sends Sif to Earth on a mission and later banishes her from Asgard.
Destruction of Asgard and death In 2017, Thor returns to Asgard and discovers Loki's ruse, making Loki reveal himself to the shocked Asgardians. After Loki tells Thor where Odin is, he is taken by Thor back to Earth to New York City. Loki is trapped through a portal by
Stephen Strange as a threat to Earth, before being dropped out of the portal into the
New York Sanctum. He and Thor are then sent into another portal to
Norway, where they find a dying Odin, who explains that his passing will allow his firstborn child,
Hela, to escape from a prison she was sealed in long ago. Hela appears, destroying Mjölnir to Loki's shock, and forces an escaping Thor and Loki from the Bifröst out into space. Loki lands on the planet
Sakaar, and quickly ingratiates himself to the ruler of that world, the
Grandmaster. Thor later crash-lands on Sakaar and is captured by the slave trader
Valkyrie, a former member of the ancient order of
Valkyries defeated by Hela. After convincing Valkyrie and Loki to help, they steal a ship with which to escape through a wormhole to Asgard – but not before Loki again attempts to betray Thor, causing Thor to leave Loki behind on Sakaar. However, Loki is found by
Korg,
Miek, and others who join him aboard a large vessel stolen from the Grandmaster called the
Statesman. He leads them to return to Asgard and help the Asgardians escape the battle between Thor and Hela's forces, proclaiming himself their savior in the process. During the battle, on Thor's order, Loki goes to Odin's treasure room and places the crown of Surtur in the eternal flame kept there, thus causing an enormous form of
Surtur to appear and destroy Hela and Asgard. In the process of doing so however, he steals the Tesseract from Odin's treasure vault. Thor, crowned king, decides to take the Asgardians to Earth despite Loki's concerns about how he will be received there. While en-route to Earth, in 2018, Loki and Thor are intercepted by a large spacecraft, the
Sanctuary II, carrying
Thanos and his
adopted children, alerted to their location by the presence of the Tesseract secretly being held by Loki. After wiping out half of the Asgardians onboard while the rest flee via escape pods, Thanos, wielding the
Power Stone, overpowers Thor and Hulk, kills Heimdall, and claims the Space Stone from the Tesseract that Loki hands over to him in order to spare Thor's life. In a last act of self-sacrifice, Loki pretends to swear allegiance to Thanos, only to attempt to stab his throat. Thanos intercepts the attack with the Space Stone and kills Loki by snapping his neck, leaving his body to be cradled in Thor's arms as their ship explodes.
2012 variant Capture and learning his original fate A variant of Loki, dubbed
Variant L1130, is subdued by the Avengers at
Stark Tower following the
Battle of New York. He is taken into custody by Thor and Stark but they get stopped by
Alexander Pierce and other agents at the Tower's entrance. Loki witnesses Stark going into cardiac arrest and sees
Ant-Man kicking the briefcase containing the Tesseract to
another Tony Stark. However, the briefcase gets knocked over by Hulk and lands at Loki's feet. Loki takes the Tesseract and escapes into a wormhole. The wormhole drops Loki off in
Mongolia and he is taken into custody by the
Time Variance Authority (TVA), while the new timeline is reset and destroyed. Loki is taken through a Timedoor into the TVA headquarters. He is taken into the TVA court room where TVA judge
Ravonna Renslayer labels him a rogue variant to be "reset", despite Loki saying that they should talk to the Avengers instead. He is told what
they did was supposed to happen. TVA agent
Mobius M. Mobius intervenes and takes Loki to a Time Theatre where he reviews Loki's past misdeeds and questions his real motive for hurting people. After Mobius leaves the room, Loki escapes and learns that the
Infinity Stones are powerless in the TVA, as they are being used as paperweights. He returns to the Time Theatre and views his main 616 counterpart's life, such as his relationship with Thor and death at the hands of Thanos. After seeing this, Loki agrees to help Mobius stop another variant of himself.
Working with the Time Variance Authority Loki goes with a TVA unit to 1985
Oshkosh, Wisconsin to look for the variant. Loki stalls for time, but Mobius understands his plan. After some research, Loki proposes that the variant is hiding near apocalyptic events like
Asgard's
Ragnarök, where the impending destruction means their actions cannot change the timeline, thus concealing them from the TVA. Loki and Mobius confirm this possibility by visiting
Pompeii in 79 AD. Travelling to 2050
Alabama, Loki meets the variant, who rejects Loki's offer to work together to overthrow the Time-Keepers, before revealing herself as a female variant. The variant then uses TVA Reset Charges to "bomb" the timeline, creating new timeline branches to keep the TVA's Minutemen busy, before escaping through a Timedoor, with Loki in pursuit.
Allying with Sylvie Loki and Sylvie engage in a confrontation at the TVA headquarters, but he using his TemPad, teleports them both to Lamentis-1, a planet set to be destroyed by a meteor shower. However, their TemPad runs out of power stranding them. Agreeing to ally with one another, the variant introduces herself as "
Sylvie" using an
alias and proposes a truce in order to escape the planet. The pair sneak aboard a train bound for the Ark, a spaceship intended to evacuate Lamentis-1, in order to siphon its power and recharge the TemPad. On the train, Loki gets drunk and starts a ruckus, causing him and Sylvie to be discovered and forced out by the guards. While walking to the Ark in order to instead hijack it and leave the planet, to prevent it from being destroyed as according to the Sacred Timeline, Loki enquires about Sylvie's enchantment ability, learning that the TVA are all variants themselves; Loki reveals to Sylvie that the TVA agents, including Mobius, are not aware that they are variants. They fight their way through the guards and through a meteor shower to the Ark, only to witness it being destroyed by a meteor just as they get to it, leaving them stranded again. Loki is told by Sylvie how she escaped the TVA when she was about to be arrested as a child. Loki and Sylvie form a romantic bond, creating a nexus event, that alerts the TVA. Mobius rescues them from Lamentis-1 and has them both arrested, punishing Loki by leaving him in a time loop from his past. After Mobius derides Loki for having fallen in love with Sylvie, Loki tells him that everyone working for the TVA are variants, which Mobius investigates. Now aware of his background upon finding proof, Mobius frees Loki from the loop, but is soon confronted by Renslayer and pruned. Loki and Sylvie are taken to the Time-Keepers, accompanied by Renslayer and her minutemen. B-15 intervenes, freeing Loki and Sylvie of their time twisting collars, and in the ensuing fight, the minutemen are killed whilst Renslayer is knocked unconscious by Sylvie. Sylvie then beheads one of the Time-Keepers, who turn out to all be androids. Loki prepares to tell Sylvie about his feelings, but Renslayer regains consciousness and prunes him. He awakens in a barren wasteland, dubbed
the Void at the end of time, and is met by other variants of himself.
Surviving in the Void and meeting He Who Remains Loki and the other variants,
Kid Loki, Classic Loki, Boastful Loki, and Alligator Loki, are chased by
Alioth, a universe-devouring cloud-storm entity. They pass several pruned objects such as a
Yellowjacket helmet and the Thanos-Copter and escape into Kid-Loki's underground tunnel. Loki is introduced to them and told that Alioth acts as a pet that protects the Void and devours anything that gets sent there. Loki is told by each of them their respective reasons for getting sent there. Loki decides to leave, but gets stopped from doing so by President Loki and other variants who barge into the tunnel. Boastful Loki reveals that he betrayed them on behalf of President Loki, causing a fight to ensue between them, while Classic Loki creates a portal for Loki, Kid Loki, and Alligator Loki to escape through. In the distance, they witness a
U.S. Navy ship arriving and Alioth subsequently devouring the soldiers. Loki then is reunited with Mobius and Sylvie, who drive up in a car. Sylvie proposes a plan to enchant Alioth, whilst Mobius leaves through a Timedoor. Kid Loki and Alligator Loki leave them while Classic Loki creates a large illusion of Asgard to distract Alioth and sacrifices himself in the process. This allows Loki and Sylvie to successfully enchant Alioth and see a rift opened, revealing the Citadel at the End of Time in the foreground, and walk towards it. Loki and Sylvie approach the Citadel and walk inside after the doors open. They encounter Miss Minutes and reject an offer from her creator, "
He Who Remains", to return them to the timeline with everything they desire. She leaves them and they continue walking through the Citadel until an elevator door opens and they meet He Who Remains. He invites them to his office and tells them about the multiversal war caused by
his infinite variants, taming Alioth to end the war, isolating a collection of universes that had no variant of his existing called the "Sacred Timeline", and creating the TVA. As the timeline begins to branch, he offers them a choice: kill him and expose the timeline to the multiverse, creating another multiversal war, or become his successors in overseeing the TVA. Loki believes his warnings and pleads with Sylvie to listen to reason after she tries to kill him. They kiss, but Sylvie uses He Who Remains' TemPad and sends Loki back to TVA headquarters. A defeated Loki warns B-15 and Mobius about the variants of He Who Remains, but they do not recognize him. To his horror, Loki sees that a statue in the likeness of He Who Remains has replaced those of the Time-Keepers.
Time Slipping throughout the TVA Back at the TVA, Loki discovers that he is uncontrollably warping across time. In the past, Loki is chased by Mobius and the TVA Minutemen. In the present, Loki reunites with Mobius and warns him and B-15 of the threat of He Who Remains' variants, telling them that He Who Remains created the TVA. Loki and Mobius go to meet TVA technician
Ouroboros "O. B.", who deduces that Loki is "time slipping", a phenomenon possibly caused by the instability of the timeline branches caused by He Who Remains' death. Loki slips to a point 400 years in the past in the same place, where he instructs O. B. to build a Temporal Aura Extractor device to stop Loki's time slipping. In the present, O. B. suddenly remembers that he has been holding onto the device for centuries, and instructs Mobius to approach the Temporal Loom with it to extract Loki from the time stream as Loki prunes himself. Loki time slips to the future, where he briefly encounters Sylvie opening an elevator before he is pruned at the last possible second. Mobius successfully pulls Loki from the time stream, and the two of them set out to find Sylvie. While in the future, Loki also witnesses the Temporal Loom going critical, forcing the evacuation of the TVA. In the present, Loki, O. B. and Mobius witness the beginning of this meltdown which O. B. begins working to stop.
Fixing the Temporal Loom Loki, Mobius, and B-15 go to 1977
London on Earth-616 and locate Brad Wolfe. They bring him back to the TVA and get him to tell them where Sylvie is. They find her in a branched universe's 1982
Broxton, Oklahoma working at
McDonalds and Loki tries to get her to come back to them, but she refuses until Wolfe warns them they are in danger of TVA general Dox's plans of pruning the new branches. They locate Dox and her Minutemen, stopping them and taking them into custody, although most of her plan had succeeded. Loki, terrified by the thought of He Who Remains' variants, convinces Mobius to find where the variants may be. They track Renslayer's TemPad and travel to the 1893
Chicago World's Fair. There, they see a He Who Remains' variant,
Victor Timely, presenting his Temporal Loom prototype. Timely flees as four groups chase him: Loki and Mobius, who want to bring him back to the TVA to use his aura to fix the Loom; Renslayer and Miss Minutes, who want him to take his variant's place with them at his side; Sylvie, who wants to kill him; and a
robber baron and his allies wanting revenge against Timely's fake invention scam. Loki, Mobius, Renslayer, and Sylvie find Timely at his Wisconsin laboratory. Sylvie relents from killing Timely and allows Loki to take Timely back to the TVA. As the Temporal Loom reaches critical, Loki and his friends attempt to fix it, but are blocked by Miss Minutes. In the midst of the group's attempts to fix the Loom, Loki encountered his time slipping past self and pruned his past self, realizing that it was actually he himself who had done it during his earlier adventure. After O. B. takes Miss Minutes off-line, Sylvie is able to enchant Wolfe into pruning Renslayer, but the temporal radiation spaghettifies Timely before he can place the Throughput Multiplier in the Loom. The Temporal Loom explodes and Loki is caught in the blast wave as it engulfs the TVA.
Forming Yggdrasil Having survived the explosion, Loki finds himself in the abandoned TVA and begins time slipping once again, barely escaping as the TVA disintegrates. Loki's time slipping takes him to the branched timelines where his friends Mobius, Hunter B-15, Casey and O. B. have been reset to their previous lives as Don, Dr. Verity Willis,
Frank Morris and Dr. A.D. Doug respectively. Of the group, only Doug believes Loki and, since Loki can't control his time slipping, proposes a plan to bring together the group that was present at the explosion to use their collective temporal aura to determine the coordinates that Loki needs to travel back in time to. Although Loki manages to collect the others, Sylvie, who retains her memories as well, is uninterested in helping and gets Loki to admit that his true motivation is a fear of losing his friends and being alone. Sylvie encourages Loki to write his own story like everyone else, but before he can send everyone home, Sylvie appears with the news that her branched timeline died and faded away. She and the group fade away as well, with Loki finally figuring out how to control his time slipping by focusing on a person rather than an event. Declaring that he can "rewrite the story," Loki successfully travels back in time to before the explosion by focusing on O. B. After centuries spent
time slipping to learn from O. B., and after successfully guiding Timely in setting up the Throughput Multiplier, Loki learns that the Temporal Loom cannot be fixed due to the multiverse as it was not equipped to handle it. Loki realizes he has to time slip back to the Citadel and speaks with He Who Remains, who tells him that he was responsible for Loki's time slipping. Loki is told that the Temporal Loom is nothing but a failsafe designed to protect the Sacred Timeline and that Sylvie must die in order to reverse what happened. Unwilling to kill Sylvie, Loki time slips to speak with past versions of Mobius and Sylvie, who tells him that they could fight the multiversal war. Believing that the TVA is the best line of defense against He Who Remains' variants and is necessary to exist, Loki decides to sacrifice his freedom by destroying the Temporal Loom, reviving the timelines with his magic, and rearranging them into
Yggdrasil. In doing so, he takes over He Who Remains' position, becoming the new keeper of time and the TVA. Inspired by Loki's actions, the TVA is reformed to preserve and protect the multiverse, and to hunt down He Who Remains' variants. Having finally found his glorious purpose, Loki sits alone on a throne at the center of the timelines that he now maintains, listening to his friends through them with a heartbroken but satisfied expression on his face. Sometime later, the
Watcher shows
Captain Peggy Carter the multiverse bringing her to Yggdrasil. ==Alternate versions==
