This version of the mythological Loki was created by Stan Lee, Jack Kirby, and Larry Lieber.

Personality
Loki is the God of Mischief and an expert liar, despite being unable to trick Thanos (although few can sucessfully trick the Mad Titan). Loki is motivated by his love for Thor and his desire of redemption for his criminal past. A cunning, gifted, good hearted and intelligent man, this along with his overwhelming ambition meansthat he never surrender.

Powers and abilities

 * Superhuman Strength: Loki possesses superhuman strength that is substantially superior to that of an average Asgardian female or male. He possesses sufficient physical strength to lift up to 50 tons.
 * Supernatural Dense Tissue: Like all Asgardians, Loki's bodily tissues have roughly 3 times the density of the same tissues in a human being. While he has the looks and physical proportions of a much smaller person, the increased density of his body actually makes him several hundred pounds heavier than he appears. This increased density also contributes to his superhuman strength to a limited degree.
 * Superhuman Durability: The tissues of Loki's body are superhumanly durable and are roughly equal to those possessed by the average Asgardian male. However, at times, Loki had imbued himself with magical abilities that enable him to withstand injuries that would prove fatal to another Asgardian if hit.

 * Intelligence: Loki has a genius level intellect and possesses a great deal of knowledge of the mystic arts,. He is also extremely cunning and skilled, an expert battle strategist, and highly skilled and charismatic manipulator.

Thor
Loki is the son of Frigga and adopted son of Odin, as well as Thor's half-brother. He is seen as an envious and a violent man who will stop at nothing to banish Thor and kill him. Loki first appeared in Thor when Thor was supposed to be crowned. As a prank to 'ruin his brother's big day', Loki allowed several Frost Giants to steal the Casket of Ancient Winters. Thor, upset by the turn of events, leads Loki, Sif and the Warriors Three to Jotunheim where a battles begins. During the fight, Loki is touched by a Jotun and does not react to the Frost Giant's freezing touch. The fight is interrupted when Odin comes and takes them back to Asgard. Odin, disappointed for Thor's actions, banishes Thor powerless to Earth until he became worthy once more by picking up Mjolnir.

Loki then appears in the armory and questions Odin about his true heritage. Odin reveals that Loki's real father is a Frost Giant, and Loki is actually a Frost Giant-Asgardian hybrid. Odin then falls into the 'Odin-sleep'. While Odin is asleep, Loki becomes king of Asgard and forbids Thor from returning. Loki then travels to Earth and tells Thor that he is banished to keep Asgard from going to war with Jotunheim and that Odin is dead.

When Loki discovers that Sif and the Warriors Three have gone to earth to retrieve Thor, he dispatches the Destroyer to make sure they do not return. Loki then brings in Jotuns to kill Odin, but later betrays them. After Thor regains Mjolnir and defeats the Destroyer, Thor then returns to deal with Loki. Loki likewise orchestrated an invasion by the Frost Giants, although he quelled the invasion and killed their leader in an attempt to gain Odin's trust. When Thor comes back to face Loki in Asgard and he tries to fight him as he wants to stop Loki from destroying Jotunheim. Thor then breaks the Rainbow Bridge that binds Asgard to other worlds. As Thor and Loki cling to the broken bridge, Odin wakes from the Odin-sleep and rescues them both. Loki then tells Odin that he could have been king and that destroying Jotunheim was for the best. Odin denies him and Loki lets go, falling into a dark abyss.

Loki is seen again after the credits, alive and well, who influences Dr. Erik Selvig to research the newly found Tesseract.

The Avengers
"Kneel before me! I said, KNEEL! Is not this simpler? Is this not your natural state? It's the unspoken truth of humanity, that you crave subjugation! The bright lure of freedom diminishes your life's joy in a mad scramble for power, for identity. You were made to be ruled! In the end, you will always kneel."

- Loki before a crowd of kneeling humans

After falling through the wormhole, Loki arrived in a part of the universe unknown to both the Asgardians and humans and came into contact with The Other, a servant of Thanos, who offered a pact that would allow him to become ruler of the Earth while Thanos and the Chitauri would take the Tesseract, the cosmic cube left on Earth being studied by S.H.I.E.L.D. Thanos gave him ancient knowledge through the powers of the Tesseract, providing him with a golden bladed staff with a blue gem that was powered by the cube itself. It acted as a very powerful weapon, and also as a mind control device, bending those who were touched by the gem's power to its will.

After accepting the deal, Loki turned his focus back to Earth in search of a suitable agent, someone close to the Tesseract. He found Erik Selvig, a friend of Thor's and a renowned astrophysicist, who had been summoned to the task of unlocking the secrets of the mysterious cube. In time, Selvig came to understand some of the Tesseract's capabilities, and through Loki's influence he developed equipment that would focus some of that power. When the time was right, Loki activated the Tesseract, forming a temporary portal that pulled him through to its location on Earth. He was immediately confronted by S.H.I.E.L.D. agents who fired guns at him only to learn that bullets bounced off of his body. Nick Fury attempted to keep him away from the Tesseract after, but Loki managed to use the scepter to subjugate and control Hawkeye and Selvig, as well as a number of other agents by placing the tip of the scepter at their chest near their heart and allowing the power of the gem to overtake them. He explained to Nick Fury that he wanted the Tesseract as part of his 'glorious purpose' which was to free the earth and humanity from 'freedom... life's great lie' as their one supreme king.

Fury tried to flee with the Tesseract, but then decided to stay and allow himself to die with the cube if it meant stopping Loki as well. Selvig and Hawkeye informed Loki of Fury's intent, prompting Loki to gather the turned agents and leave with the Tesseract after attempting to kill Fury, avoiding Maria Hill's attempt to stop them. The energy it had unleashed consumed the area and the entire S.H.I.E.L.D. compound with it. After securing an area to determine the next course of action for the cube, Loki noted the scepter's gem glowing and calling out to him. He allowed himself to enter a trance where he could appear to the Chitauri leader and his army in a metaphysical form. The Chitauri leader warned Loki that if he failed at his pursuit of earth and the Tesseract did not fall into their hands to be given to Thanos, that there would be no place for him to hide from the overlord's wrath and that he would beg for something as sweet as pain. Now unsettled about potential failure and more determined than ever, Loki went to Stuttgart, Germany with Hawkeye and other turned agents in order to retrieve iridium, necessary to stabilize the portal.

Here he disrupted a gala at a large museum while Barton raided a secure installation for iridium. Loki struck terror into the hearts of patrons and guests by securing the one thing needed for Hawkeye to breach the iridium lock's security measures: the curator's eyeball. Loki strode out after the screaming crowd into the streets where he made several copies of himself, trapping the people and demanding that they kneel before him. Loki bragged that this was man's purpose, but a single man challenged him and his intentions. When Loki prepared to kill the old man, Captain America appeared and challenged him. Seconds later, the Quinjet carrying Black Widow also challenged him from the sky. After a brief battle with the super-soldier, during which Loki had the upper hand, Iron Man arrived and threatened to fire upon Loki, daring him to make a move. Outnumbered, he allowed himself to be captured, secretly plotting to use this to his advantage. As they journeyed to the S.H.I.E.L.D. Helicarrier, Thor arrived and extracted Loki from the jet.

Thor attempted to reason with Loki, imploring him to remember that they were brothers (even if not by blood) and to return home to Asgard and surrender the Tesseract. Loki, however, still resented his brother, and refused to cooperate. Thor was tackled by Iron Man before he could say any more, and Loki remained on his perch as he watched them battle before agreeing to ally themselves. They took him into S.H.I.E.L.D. custody aboard the helicarrier, where he was placed in a confinement capsule designed to hold the Hulk. Loki taunted Fury about his attempts to control the Tesseract and his gathering of misfits to defend Earth. Loki's mere presence was enough to provide a disruptive element that would fragment the only group of heroes that had any hope of stopping him. When Black Widow arrived to speak with him, apparently to offer a deal in exchange for Hawkeye's freedom, he subjected her to a play of wits where he ferreted out her deeper misgivings, but was completely caught off guard when she tricked him into revealing that there was already a monster among them and that it was not him. From this, she concluded that the monster was Banner and that he had planned to use the Hulk to destroy the ship and the heroes as well.

However, Loki's plan to use the Hulk, only one aspect of his real intentions, did follow through as another jet carrying Hawkeye and the rogue agents came to his aide, following a signal from the scepter. The wounded Banner transformed into the Hulk, destroying much of the helicarrier, while one of Loki's controlled agents freed him from the cell. Loki then used illusions of himself to trick Thor into entering the cell and to distract Agent Coulson. Loki mortally wounded Agent Coulson and ejected Thor's cell from the helicarrier. Though he retrieved his scepter, Hawkeye was released from the mind control, and Loki headed to New York, where Selvig waited with the Tesseract at Stark Tower.

Loki prepared to welcome his army and begin his glorious, but brief, war on the earth. Tony Stark, still alive after the raid and having figured out his plan, caught up with him at the Tower and abandoned his wrecked Iron Man suit to threaten him. When Loki grew weary of the threats he tried to subjugate Stark with the scepter, only to be physically blocked by the arc reactor. Annoyed, he threw the inventor out of a window, and was surprised when a freshly built Iron Man armor rocketed out after the man. Loki found himself briefly under attack when the fully suited Iron Man rocketed back up to retaliate before the Tesseract opened the portal, allowing Loki's Chitauri army to come pouring through. With his triumph near at hand he was confronted by his brother, Thor, who demanded that he at once deactivate the Tesseract or the thunder god would destroy it. Loki refused, claiming that nothing could stop his war.

The brothers fought a second time, Loki's scepter matching Thor's hammer. Blasts from the gem almost completely destroyed the Stark Tower logo on the side of the balcony, blasting the giant letters and debris off the side. When the confrontation came to stalemate with them grappling each others' necks, Thor urged Loki to look around him at the destruction he caused and asked if he truly believed it would all end with his rule. While Loki was unsure of himself, his eyes reverted to their normal green state temporarily as he claimed it was too late to stop the madness, but briefly considered Thor's appeal to work together to end it all and redeem himself. The will of the Tesseract over his mind was stronger than his guilt, however, and he instead stabbed Thor with a throwing knife, preparing to strike him down with the scepter as he knelt before him and laughing in amusement at the sentiment. This did little more than enrage the thunder god, who disarmed his adoptive brother of his staff and picked him up before slamming him down hard on the ruined balcony.

Loki threw himself off the building as he was defeated and managed to land on one of the Chitauri's small flying craft. From there, he led an attack on the city. When the first of the Chitauri's massive Leviathans was destroyed by the Hulk, he commanded the Chitauri on the other side of the still-open portal to send the rest of their massive armada, overwhelming the city's defenses. An aerial chase after Black Widow left his craft destroyed by one of Hawkeye's arrows and Loki landed back on Stark Tower, where the Hulk confronted him. Loki's frustrated rant goaded the Hulk into simply picking him up and repeatedly slamming him into the ground. Loki was too stunned to fight or threaten any longer, more wounded physically than he had ever been before.

When he eventually summoned the strength to crawl, he found himself face to face with six of the Earth's mightiest, having defeated the Chitauri army and closing the portal, he quietly requested the drink that Stark had offered before. After the Tesseract was relinquished to Thor, Loki was bound and placed in a metal muzzle (likely to prevent pleading, threatening, or perhaps use of magic) and led to an open area in Central Park with his brother. From there, Thor used the power of the Tesseract to transport both of them home to Asgard.

Thor: The Dark World
Continuing from The Avengers, Loki is taken back to Asgard and brought to his father Odin to answer for his crimes. While Frigga is more than relieved to see him alive, Odin is disappointed in his crime for not only causing treason, but for also leading the Chitauri attack on New York. Loki shows no sign of remorse, thinking he committed a benevolent act as a god. Odin thinks otherwise and adds that if it weren't for the compassion of Frigga, Loki would probably be dead. Odin sentences him to spend the rest of his days in the dungeon. While Loki dwells within confinement, he watches from his cell as Fandral and Volstagg bring in some prisoners, including a disguised Algrim. Loki is visited by Frigga, in the form of a hologram, and expresses her concern toward him, he still has deep compassion for his mother though he brushes it off, becoming further doubtful of his family's acceptance of him.

When Algrim, who turns into a Kursed, causes a prison break, Loki's cell is left untouched by the dark elf, but he does give advice to Algrim on how to sabotage Asgard's defenses. Loki then returns to his boredom, but is then informed by a guard that Frigga was killed in the attack, evidently causing despair for Loki, as he nearly destroys everything in his cell in a fit of grief and rage. It is not until later on that Thor eventually comes to Loki and sees the effect Frigga's death had upon him. Thor then offers Loki his freedom in exchange for aid against Malekith, in order to enact vengeance for Frigga. Loki knows that Thor is desperate to come seek help from him, though Thor believes that the man he once called his brother is still in Loki. He agrees to help Thor in using diversion tactics. When they meet with Jane Foster (the current host of the Aether), and Sif, Jane slaps Loki for his attack on New York. Sif also promises to kill Loki if he betrays them. With the aid of his allies, Thor, Loki, and Jane escape into the crashed dark elf ship. The Asgardian warriors chase after them until they hop out of the ship and onto a smaller craft flown by Fandral. As he lets the trio make their way out, Loki uses a hidden passageway within Asgard to get to Svartalfheim.

Once they arrive, Loki betrays Thor by stabbing him and then slices off his hand to prevent him from summoning Mjolnir. He throws Jane before the dark elves, claiming his allegiance with them to spite Asgard. Malekith begins to transfer the Aether within Jane to himself. However, the process is interrupted by Thor, where it is revealed that Loki's betrayal was all an illusion to allow Thor to attack unexpectedly. Thor then uses Mjolnir to destroy the gathering Aether with lightning; unfortunately, as Aether cannot be destroyed, the substance quickly reforms and completes its transfer into Malekith. Malekith and the dark elves then make their way toward their giant vessel as Thor attacks them. Algrim throws one of their vortex weapons in the air, which almost catches Jane. But Loki pushes Jane away from it, and is nearly sucked in until Thor pulls him away. Thor fights back against Algrim, but the Kursed beast brutally beats him down. Algrim proceeds to kill Thor himself, but Loki uses a sword to stab Algrim from behind. However, the sword proves ineffective on Algrim, who then grabs Loki and impales him with the very sword he had used against him, and is thrown to the ground. While Algrim gloats in his victory, Loki declares, "See you in Hel, monster," as Algrim quickly realizes that the blade is attached to his own vortex weapon, destroying Algrim before he can react. As Loki lies dying, Thor clutches his brother in his arms, calming him down and vows to tell Odin about Loki's deed, but it is too late; Loki replies to Thor, "I didn't do it for him" before closing his eyes and quietly dies as his skin returns to its blue Frost Giant form. A grief-stricken Thor is left to mourn for Loki's sacrifice.

After Thor and Jane depart for Earth, Loki awakens, confirming his death to be false and disguises himself as a warrior and returns to Asgard to tell Odin that Thor had disappeared with his hammer left behind, and reports to Odin that Loki's body has been found.

After Thor defeats Malekith, Thor returns to Asgard and declines Odin's offer to take the throne while telling Odin of Loki's sacrifice. He offers Mjolnir to Odin, but he tells him it belongs to him if he be worthy of it. Thor thanks Odin and walks away. As he leaves, Odin's image shapeshifts into none other than Loki. Now seated in the throne he had long desired, he quietly answers, "No. Thank you."

Thor: Ragnarok
Four years after the events of The Dark World, Loki continued to rule Asgard still under the disguise of his adoptive father, Odin. It is revealed that Loki did not kill his father and merely sent him to live on Earth under a spell. Although Loki was able to keep up the act, eventually Thor realizes that Loki is, in fact, alive. To prove it to be true, Thor holds his brother with his hammer hand and threatens to have Mjolnir hit Loki in the face. The former king quickly changes back from Odin and into Loki and promises to lead him to where their father is.

The two of them come to Earth where Loki left their father in a nursing home, only to find the whole building to be demolished.

Detecting the two in New York, Doctor Strange imprisons Loki in an endless loop and only releases him after striking a deal with Thor. Upon arriving in Norway, they find Odin. Much to Loki's surprise, Odin has lost any animosity he had towards him and even says that Frigga would be proud that Loki could cast a spell on him. Loki watches with concern as Odin reveals that he is dying and was shocked when Odin reveals the existence of Hela, their sister. Loki watches on as Odin dies, afterwards Thor angrily confronts Loki and furiously blames him for Odin's death.

However, before Thor threatens Loki, Hela arrives from her prison and confronts the brothers. Loki approaches Hela and tries to peacefully talk to her, and Hela sarcastically notes he sounds like Odin.

As Hela proceeds to attack them, Loki orders to Volstagg to bring them back to Asgard with the Bifrost but in the portal, he and Thor are chased by Hela. Loki is kicked out of the portal by Hela and falls to an alien planet named Sakaar, where he meets the ruler of the planet, Grandmaster. Believing Thor perished in the Bifrost, Loki allies with Grandmaster to survive the planet. Weeks after his arrival, Loki is shocked to find Thor is alive and brought to the Grandmaster. When Grandmaster asks to Loki if he knows Thor, Loki, to maintain his ties with Grandmaster, denies before Thor adds that they are brothers. As Loki is unable to directly help him, Thor discovers he must first defeat the Grandmaster's champion to earn his freedom.

Later, Loki uses an illusion of himself for visit Thor in his prison cell and proposes to Thor to join him and the Grandmaster. However, Thor refuses to talk and remains adamant of returning to Asgard, and still blames Loki for Odin's death and Hela's appearance. Despite his concern for Thor, Loki leaves unable to persuade Thor, although he warns him that the Grandmaster's champion is extremely savage. Loki then wishes luck to Thor in his fight.

In the Grandmaster's quarters, Loki watches Thor in the arena when he and his brother discover the Grandmaster's champion is Hulk. Loki, remembering what Hulk did to him in New York, tries to leave Sakaar but is encouraged to stay by the Grandmaster. Loki watches his brother fight the green monster but luckily, Thor taps into his storm abilities to weaken the Hulk to Loki's shock. However, Thor ultimately loses the fight due to the Grandmaster's intervention, although he survives.

Later, Thor and Hulk escape and attempt to leave the planet, so the Grandmaster orders to Loki and Scrapper 142 to capturing them. Loki and Scrapper then fight for the bounty, during which Loki finds out Scrapper 142 is a lost Valkyrie and makes her relive the moment when Hela killed all of her teammates, but Valkyrie regains her senses and punches Loki unconscious. Loki is then imprisoned with chains by Valkyrie who decides to help Thor for revenge on Hela.

After Valkyrie shows Loki to Thor as a peace offering, Loki sees Bruce Banner, who makes it clear he doesn't trust Loki, although Loki still makes Bruce uncomfortable with his volatile ambitions. Loki offers to help Thor to use the Commodore to escape from Sakaar and Thor accepts, so Loki is freed and the four join together as the Revengers. The group then start a revolution on Sakaar and free the other gladiators. Loki and Thor defeat the guard to retrieve the ship. Once they find the Commodore, Loki tries to betray Thor to escape Sakaar but Thor expects this and activates the control disk he surreptitiously placed on Loki, paralyzing Loki into submission. Before he leaves, Thor encourages Loki to be more than he is now and he leaves the remote to the disk away from Loki.

Loki remains paralyzed until Korg and the Saakarian Rebels find the remote and deactivate the disk. Loki thanks Korg and request that he join them in their escape to help Thor defeat Hela, eager of redeeming himself. Together, Loki and the rebels escape from Sakaar sailing in the Statesman.

Loki and the rebels then arrive on Asgard to help evacuate the Asgardians to the Statesman and fight off Hela's army. While Loki, Thor, and Valkyrie confront Hela, Thor realizes they must revive Surtur to stop Hela. Instructed by Thor to retrieve Surtur, Loki goes to Odin's Vault and takes Surtur's crown and, noticing the Tesseract, takes it with him. Loki then throws Surtur's crown into the Eternal Flame and teleports himself with the Tesseract to outside as Surtur arises now a giant. Loki escapes with Thor, Hulk, and Valkyrie on board the Statesman while Surtur destroys both Asgard and Hela. Inside the ship, Loki appears to Thor remarking that Thor (sporting an eyepatch) now looks like their father. Assuming Loki already left them, Thor jokes if Loki was there, he would hug him before realizing Loki is physically present. The two reconcile and make their way to the other Asgardians, where Thor decides to bring them to Earth as their new home.

In a mid-credits scene, the redeemed Loki is uncertain if the humans will accept him on Earth after all he has done, but Thor assures them everything will be alright, Just then, the Sanctuary II ship blocks their path and they are boarded by Thanos.

Avengers: Infinity War
After Thanos and the Black Order decimate half of the Asgardians on board the ship, Loki finds himself at knifepoint by Proxima Midnight and at the mercy of Thanos as the latter threatens Thor's life to get Loki to give up the Tesseract. Loki complies and gives the item to Thanos, who crushes it to gain the Space Stone, before revealing he was distracting Thanos so that Hulk could get the drop on the Mad Titan. Hulk puts up an impressive fight until he is swiftly defeated by Thanos in combat. Hearing Thanos prepares for Earth to gather the remaining Infinity Stones, Loki pretends to offer his loyalty to Thanos while preparing a dagger to stab him. Unfortunately, his act is seen through by Thanos as he stops Loki from carrying out his attempts using the Infinity Gauntlet.

Thanos mocks Loki for his effort, but Loki remains defiant and warns Thanos that he will never become the god he seeks to be. An unfazed Thanos ignores Loki's words and he apparently crushes Loki's neck, dropping his body nearby a horrified Thor prompting the thunder god to cry helplessly. Following the ordeal, Thanos and his underlings leave Thor with Loki's body as they destroy the Statesman and Thor is left floating among the debris.

Due to the fact that Tom Hiddleston is confirmed to return as Loki in Avengers 4, it's likely that the Loki who is dead was an illusion of himself or a clone and the real Loki escaped on a escape pod and joined Valkyrie and the refuged survived Asgardians.

The Avengers: Earth's Mightiest Heroes
In this incarnation, Loki is more or so the same as the comic book incarnation of Loki (unlike his current animated counterparts).

Loki tries to conquer Asgard with the Frost Giant army, but they are defeated by his adoptive brother, Thor, and he takes Loki to Odin after a short fight. Odin banished him to the "Isle of Silence". It is revealed that he manipulated the whole situation with help from the Enchantress who later frees him from the Isle and says that "no one is ready for what comes next" before making a long sinister laugh. Loki appears again as a silhouette speaking with Enchantress.

To prepare for this victory, Loki manipulated the whole situation of Thor where he posed as the Leader to have the Wrecking Crew attack a boat containing a shipment of Stark Industries technologies, had Enchantress in the form of a woman send Thor that way, and posed as Balder to tell Odin about Thor's actions on Earth. After the Frost Giants were defeated, Loki ended up fighting Thor and was defeated. Loki was then brought before Odin who banished Loki to the "Isle of Silence" where he can not use magic and trickery. After the Enchantress frees him from the Isle, Loki sends her to gather the Masters of Evil to start the next phase in his plan.

After the Avengers destroy the Norn Stones, Loki takes to the throne and had Thor imprisoned in Asgard. He told Thor that he was responsible for anything that happened to Thor for causing his banishment from Asgard, causing the supervillain breakout, forming of the Masters of Evil and while he was occupied, Loki took over the rest of the Nine Realms. Thor told he failed to take over Midgard, which was responsible of the Enchantress' love for Thor. Thor also told him that the Avenger will stop his schemes, but Loki laughed maniacally since he believed that the Avengers would not survive in the Nine Realms. Loki then orders Thor to be executed, but before this is carried out, the Avengers arrive along with the rest of the resistance. Enraged about the arrivals of the mortals, Loki calls forth the Asgardian Wolf Hoarfen. He watches how the Avengers took on the wolf and is chided by Thor about the underestimating of the mortals. Loki boasted about himself to be powerfully with the Odinforce in his command, but when Thor questions why he has not still win the war yet, Hoarfen crashes into the throne room where the Avengers, the Warriors Three, Sif and Faradei arrive.

Loki laughs maniacally and challenges the Avengers, taking them easily all out. He walks towards Captain America, telling him not to go against him anymore and breaks his shield. Before Loki can finish them off, Iron Man arrives in his new armor. Noticing that his armor was made of Uru, Loki challenges Iron Man in the sky above along challenged by Wasp, Hulk and Captain America. Thor eventually arrives to fight him as well, but to no avail as Loki goes berserk with the Odinforce. Meanwhile, the other Avengers destroy the Tree of Life which causes a new one to grow out, returning Loki's power over the Odinforce to Odin and allowing the allfather to reawaken. Cornered by the Avengers, Loki still chooses to fight them until he is approached by the waking Odin, enraged by Loki's actions. Instead of sending him to the Isle of Silence, Odin sends Loki to a dimension where he was trapped and in which he is tortured by the Midgard Serpent with its acid saliva dripping on the eyes of the Asgardian.

Some time after his banishment, the Enchantress visits Loki and strikes a deal to get him to kill Thor. After Loki agrees to it, the Enchantress puts Loki's soul into the Destroyer and sends him to Midgard. There, he battles Thor, Iron Man, Captain America and Hawkeye, all of whom had been made powerless by the Enchantress (except for Hawkeye). The spell is broken, when Thor discovers humility, enabling the restored heroes to defeat Loki. After his defeat, Loki's soul returns to his body. When his soul was back in his body, the Enchantress tells the Midgard Serpent that it can have him, much to its delight.

Since that was the final episode that he was featured in, it remains unknown if Loki is ever freed from the Midgard Serpent.
