At the end of the movie Thor 2: The Dark World, Loki, the god of trickery, disguises himself as Odin and becomes the ruler of Asgard, while Odin, the father of the gods, is sealed and exiled to Earth!

Under Loki's management, Asgard was loose and without a sense of crisis, and even Heimdall, the most loyal gatekeeper of the Divine Domain, was banished and exiled! When Thor arrives in Asgard, he punctures Loki's ruse and captures Loki to earth to find his father Odin. With the help of Doctor Strange, the two succeed in finding Odin, who is recuperating in Norway, and Odin tells them that the twilight of the gods has arrived and that their sister Hela, the goddess of death, is about to be resurrected, after which Odin disappears without any worries!
It didn't take long for the resurrected Hela to come to Earth and appear in front of the two brothers. Thor, unwilling to submit to Hela, prepares to fight with him, but the powerful Hela smashes Thor's hammer with one hand. Loki, who saw this scene, knew that the two were not Hela's opponents at all, so he quickly summoned rainbow bridge to flee with Thor, who knew that Hela was in hot pursuit, and between the electric light and flint, the two brothers were all thrown to the alien planet Saka (the edge of the known and unknown worlds)! Loki, who has fallen to Saka, becomes the guest of the Saka Grandmaster through his tongue, while Thor, who falls to the junkyard, is tied up and captured by a female samurai and sold to the Saka Grandmaster as a gladiator.
On the other hand, Hela killed a large number of soldiers and civilians in Asgard who refused to submit to him, and knocked out the frescoes on the walls of the palace. It turned out that Hella and Odin fought together in all directions, but because Hella was too ambitious, she was locked up by Odin. Hela then used the Eternal Fire to revive his army and the wolf mount Fenrir (Fenris), sending them to hunt down innocent people in Asgard who refused to submit to him. Fortunately, Heimdall, the gatekeeper, was there, who helped the people to hide and escape the pursuit.
At the Saka Arena, Thor meets his friend Hulk, who has been lost for more than two years. But at this time, the Hulk was dumbfounded, completely unable to remember the previous events, and began to beat Thor violently, the two were equal in strength, the fight was inextricably linked, and no one won anyone. However, Grandmaster Saka, fearing that the Hulk would not be able to defeat Thor after the awakening of the divine power, directly knocked down Thor with an electric shock. After waking up, Thor asks Hulk to help him rescue Asgard and persuades the female warriors to return with them. And the female warrior was once a member of the Asgardian Valkyrie Legion, when Odin sent the Valkyrie Legion to meet Hela, unfortunately, she was the only one left in the team to live and wander to the planet Saka, where she did not want to face the past, and has been drinking wine to dispel her sorrows and live in confusion until now!
Ready to leave, Thor finds the Kun-style fighter that the Hulk drove and successfully unlocks it. At this time, the Hulk Hulk rushed in and made a violent attack, but as soon as he saw the video image left by Black Widow on the fighter, the Hulk instantly regained his sanity and changed back to Dr. Banner. In Avengers 2: Age of Ultron, in order to no longer cause damage to The Earth, the Hulk alone pilots a Kun fighter jet to the planet Saka!
Due to the Hulk's recklessness, the fighter plane was destroyed, so Thor had to find another way to get out of here. After that, Thor secretly drives the Saka Grandmaster's Commander spaceship and takes the Hulk and the Female Samurai to asgard, while Loki and the other Saka Gladiators follow in a giant spaceship.
In Asgard, Thor fights Hela, who is no match for Hela and is wounded in one eye. When he saw that he was about to be completely defeated, Thor saw his father Odin in a trance, and under Odin's enlightenment, Thor once again awakened his divine power. However, after the awakening of the divine power, Thor was still unable to defeat Hela, and even the strongest lightning power had no effect on Hela.
On the Rainbow Bridge, the gatekeeper Heimdall is evacuating with a large number of civilians, but is surrounded by the giant wolf Fenrir (Fenrir) and hella's legions. At a critical moment, the female samurai and Dr. Banner appear, and Dr. Banner transforms into the Hulk vs. the Giant Wolf, defeating him in the deep water. Heimdall and the Samurai struggle to fend off the Hella Legion, and at this critical moment, Loki makes a brilliant appearance and transfers all the civilians to the giant ship.
Asgard is the source of Hela's power, and only by destroying Asgard can he defeat Hela! The enlightened god of thunder tells Thor that we are not trying to stop the gods from twilight, but to trigger the twilight of the gods, so that we can destroy Hela. Then let Loki travel to the bunker to resurrect the Flame Giant Surtel, loki arrives at the bunker and places the Surtel Crown in the Eternal Fire. After the resurrection of the Flame Giant, Hela rushed up to confront the Flame Giant alone, and the Flame Giant, who was not willing to let the source of power be destroyed, rushed up to confront the Flame Giant alone, but in exchange for the fate of being completely destroyed, the Flame Giant inserted the Twilight Sword (Flame Sword) into the asgardian ground, and in an instant Hela and Asgard disappeared into the vast universe.
At this time, the people of Asgard also boarded the ship safely, and Thor took them to Earth. On the distant spaceship, Thor and the crowd looked at the flaming home and had mixed feelings.
Surrounded by the crowd, Thor became the new king of Asgard. It was also at this moment that Loki, the god of trickery, had begun to truly abandon his dream of becoming King of Asgard and began to support his brother Thor. That is, in the movie "Thor 3: Twilight of the Gods", Loki, the god of Marvel's tricks, has completely turned right and become a true messenger of justice!
