As in the comics, Loki has generally been a villain in the MCU, variously attempting to conquer Asgard or Earth, and having allied himself with more powerful villains to achieve his aims.
Loki (Tom Hiddleston) was introduced in Thor as the jealous younger brother of the titular hero, making moves to steal Asgard's throne. He made his next appearance in The Avengers as the main villain.
Loki is considered a trickster god, known for being neither fully good nor evil since his main aim was always to create chaos. Despite his father being a giant, he is still counted a member of the Aesir—a tribe of deities including Odin, Frigg, Tyr, and Thor.
Loki, the God of Mischief, became the God of Evil. But, in time—thanks to a little bit of influence from his heroic brother—Loki became an agent of chaos instead of evil. From supervillain to a Young Avenger, Agent of Asgard, and even the Sorcerer Supreme, Loki's journey in the comics has been anything but predictable.
Instead, rather than trying to be the Chosen One, Loki shut himself off and turned evil as he felt the love was an illusion that would fade, hurt him and he'd eventually be seen as the enemy and a failure.
The Loki whom fans fondly remember is the one who returned to Asgard, evacuated its people from Hela's (Cate Blanchett) attack, and joined Thor on his journey to Earth. In the eyes of many, Loki was redeemed and finally became one of the good guys. . The protagonist of Loki is not the same person.
Some people utterly believe that Loki sacrificed himself for his brother's sake, and the truth is his actions and words alone were very telling―he loves Thor, he always has, and though both have their disagreements, he would easily trade his life for his brother's.
The Avengers may hate the villainous brother of Thor, but they regard him with human hate, whereas Loki carries the ever-growing and ever-persistent self-loathing of an ageless god.
On Asgard, Loki finally proves himself to be a hero and has all the Asgardians get on the Statesman.
Loki, Prince of Asgard, Odinson, rightful heir of Jotunheim, and God of Mischief, is burdened with glorious purpose. His desire to be a king drives him to sow chaos in Asgard.
Villains usually enjoy hurting people. The question becomes, does Loki enjoy hurting people? “I don't enjoy hurting people,” is his answer. “I don't enjoy it.
But maybe that's another question left for Hiddleston to answer himself. The bottom line is, we love Loki because Loki is human… Well, metaphorically speaking, given he's a Frost Giant with Asgardian pride. But in a cinematic world of clearly defined good guys and bad guys, his emotional depth is pretty refreshing.
The main villain prior to Thanos' introduction, there are many times Loki proved himself to be the best villain in the MCU. The Marvel Cinematic Universe has had a lot of great villains throughout its movies, with few being as beloved or iconic as Loki.
KING LOKI. By far the most evil incarnation of Loki, and one of his oldest. During the AGENT OF ASGARD run, King Loki was literally the worst enemy of his younger self.
Loki has appeared in Thor, The Avengers, Thor: The Dark World, Thor: Ragnarok, Avengers: Infinity War, Avengers: Endgame, and Loki, making him so far the most recurring villain of the series. Loki is also one of two characters to be the main antagonist in more than one film, the other being Thanos.
Thor is one of the main heroes of the series and can be seen as a central character.
Thanos is one of the main antagonists of the Marvel Cinematic Universe, serving as the main antagonist of the Infinity Saga and the posthumous overarching antagonist of the Multiverse Saga.
Why did Loki turn into a woman? In the comics, Loki is reborn as a woman, known simply as Lady Loki, after the events of Ragnarok in Asgard, but even that wasn't too innocent: When Thor and his fellow Asgardians are to be reborn in new bodies on Earth, Loki actually stole the body intended to be for Sif.
Loki tampered with the signal, but it was received by not only Thor, but also Ant-Man, Wasp, and Iron Man. All four heroes handled Loki and even made amends with Hulk before deciding to join forces as the mighty Avengers.
Thor despises Loki for tricking everyone into believing that he had passed away. After all, Thor was mourning the loss of his brother when it was discovered that the God of Mischief was still alive. Meanwhile, Loki hates Thor for being next in line for the throne of Asgard.
While in Leah's cave, Loki told Thor everything he had done since the war against the Serpent to his alliance with the Manchester Gods. Though Thor was angry with Loki's actions and berated him, the boy burst into tears and cried out that he was only trying to help.
Thanos employed Loki to invade New York, offering him his army in exchange for Loki getting him the Tesseract which would later be revealed as the Space Stone. Even when he was power-hungry and arrogant, Loki was smart enough to know to fear Thanos.
And yet, for all that's the case, anyone familiar with the Norse legends will know Thor's one true love is in fact the Lady Sif. This truth is demonstrated in the Thor: Son of Asgard series, which reveals how Thor first became worthy of Mjolnir.
Loki and Thor are both gods and have immense godly powers that make them somewhat impervious to harm, though they can be beaten; they can lose eyes (Thor) and they can die (Loki). If the metric is physical strength, then Thor is easily the winner.
Loki often hid a degree of jealousy that Thor was to become King, and felt that Odin perhaps favoured Thor over him. As Thor was always the center of attention, Loki found himself longing for a spotlight over the years, which manifested itself in extreme attention-seeking behaviour.
