From his first MCU appearance in 2011's Thor, Loki revealed his ability to create duplicates of himself and fake his death. At the end of the film, Loki was seen careening through space to his apparent death, only to resurface during the end credits scene.
Loki has always delighted in cheating death, manipulating others into believing he was dead in order to hatch his next scheme. At the end of Thor, he apparently took his own life — but Loki survived death by plunging into one of the many portals he knew could be found in Yggdrasil.
Loki seemingly fell to his death at the end of the first Thor movie. The entire film was a struggle for the character as he dealt with living in Thor's shadow, learned his true Frost Giant lineage, and desperately tried to prove himself to his adoptive father, Odin.
With the help of the Chitauri, Loki opened a portal to Earth and arrived at an underground S.H.I.E.L.D. facility where Thor's friend, Dr. Erik Selvig (Stellan Skarsgård), was studying the Tesseract—aka HYDRA's secret weapon.
So, to be fully clear, Loki only ever actually died one time. When he dropped from the bifrost in Thor, he didn't die, but rather went directly into a wormhole that eventually led him to a world called Sanctuary, where he met a guy you may have heard of: Thanos.
With Odin disapproving of his actions, Loki allowed himself to fall through the deep abyss of space, entering a wormhole created by the sudden termination of the Bifrost Bridge. Transported by the wormhole to Sanctuary, Loki encountered The Other who offered to serve under Thanos' command and gave him the Scepter.
Ages ago, Odin fought and defeated Laufey and the Frost Giants of Jotunheim in a great war. Abandoned and left for dead as a baby due to his diminutive size, Odin took Loki, son of Laufey, to Asgard to raise him as his son and a prince in order to one day unite the Frost Giants and the Asgards in peace.
Stormbreaker has the additional power to summon the Bifröst, allowing Thor to teleport anywhere in the Nine Realms. Screen Rant has identified Stormbreaker as the more powerful of the two, based on this ability, as well as it being a much larger and edged weapon.
Here, holding on to all of the timelines, he became a kind of tree god, physically representing the Norse tree of life, Yggdrasil. It was a poignant and painful ending for Loki, who now seems to be sentenced to being alone for eternity as he watches over the timelines.
This stemmed from his childhood and the belief that Odin didn't love him. While Odin's hiding of Loki's true parentage and Thor's demeaning behavior may have influenced Loki, ultimately he is to blame for his villainous actions due to his own issues with self-acceptance and misinterpretation of his upbringing.
Although Loki was unusually small, he still initially had blue skin and red eyes like other Frost Giants. He transformed to look like an Asgardian after Odin picked him up, though, and continued to appear that way even after Odin died.
Loki laughed in disgust, both at Thor's newfound "love" of Frost Giants, and his apparent naivity- he explained that he despised the race even more now that he knew he was one.
But if you're wondering how he's even alive, we have the details you need to know. Loki is a Trickster, and he's very good at what he does. From his first MCU appearance in 2011's Thor, Loki revealed his ability to create duplicates of himself and fake his death.
It's not unlike Iron Man's sacrifice in Avengers: Endgame, except that Loki doesn't die. So, while Loki is still alive and could technically return in the MCU, the Loki season 2 finale does give him a fitting sendoff if it's his final appearance.
Believing that Loki was of no benefit to him during this skirmish due to his lack of physical strength, Kurse decided to leave Loki inside his cell, who went on to give Kurse directions as to find what he was looking for within Asgard.
Many viewers have pointed out that Thanos was able to lift Stormbreaker without a problem, but this is because the ax isn't enchanted as Mjolnir is. Others believe Thanos lifted Mjolnir (although briefly) and have even argued that he would be worthy of doing so.
While no one besides Thor has been able to truly wield the awesome might of Stormbreaker, Groot was the very first being to hold this weapon when one of his arms became the handle for the mighty axe.
The movie doesn't explain Thor's motivations for giving up Stormbreaker, but it makes sense that Chris Hemsworth simply wanted Love to have a powerful weapon to aid her in battle. It's unlikely that he could give her Mjolnir, considering that so few people in the MCU have been deemed worthy of its power.
Now Odin did tell Thor he was stronger then him (Odin) which some interpret as Odin meaning Thor is stronger than Odin cause Thor now has his fathers power plus his own. But we have to remember two things. Odin himself said Mjølnir only channeled Thor's power, Thor just needed to learn to use it naturally.
In modern literature (such as Marvel Comics) it has become popular to portray Loki as the adopted son of Odin. This however has no basis in Norse mythology, where Loki is portrayed as the blood brother of Odin.
When Odin's own wife Frigga was killed at the hands of the Dark Elves' leader Malekith, Odin vowed revenge on them, no matter the cost, putting him at odds with his son. After faking his death, Loki cast a spell on Odin, banishing him to New York City while masquerading as Odin and ruling Asgard himself.
Yes Loki is dead, he got killed by Thanos in Avengers Infinity War (2018). But the Loki from the Loki series, is indeed Loki, but not the same Loki that died in Infinity War.
The short answer is that he's a God. There's more to it, some of it was that Loki's “Time Slipping” actually was the temporal energies of the Loom trying (and failing) to “spaghettify” him. So he was already as unstuck from time as he was going to get.
After Loki arrived on Earth and used the Scepter's power to build a small army of human soldiers, including Erik Selvig and Hawkeye, he went to a flashback where he was speaking to Thanos, with the Other being the one who was speaking with him on behalf of Thanos.
