Thor (Chris Hemsworth) landed on Earth in the 2011 standalone movie after his father, Odin (Anthony Hopkins), deemed him unworthy, stripped him of his armor and powers, and cast him out of Asgard.He first encountered Jane (Natalie Portman), her intern Darcy Lewis (Kat Dennings), and astrophysicist Erik Selvig (Stellan Skarsgård) in a desert in New Mexico as they were investigating an aurora-borealis-esque phenomenon.In 2015's Avengers: Age of Ultron, Thor mentioned that Jane's work on the convergence in Thor: The Dark World (2013) made her the world's most popular astronomer. Little is known about Jane's life prior to the events of the first Thor film. She attended Culver Universe, where her dad and Erik met. Jane also has an ex-boyfriend named Donald Blake, M.D., who she described as good with patients and bad with relationships.After returning to Asgard at the end of the first Thor movie, he and Jane didn't reunite until Thor: The Dark World, which took place after the events of The Avengers (2012). When the God of Thunder returned to Earth, he told Jane that he was preoccupied with trying to bring about peace among the Nine Realms. But by the end of Thor: The Dark World, Thor left Jane again, this time to figure out some stuff with his dad on Asgard. It sounded like their relationship started to become rocky in Age of Ultron. When asked why Jane wasn't at Tony Stark's (Robert Downey Jr.) party, Thor said he wasn't even sure what country Jane was in at the moment.By 2017's Thor: Ragnarok, after snapping a photo with two girls on Earth, one of them said they were sorry to hear that Jane dumped Thor. Thor tried to convince Loki (Tom Hiddleston) that it was a mutual break-up.Early in Avengers: Endgame (2019), Captain America (Chris Evans), Tony, Rhodey (Don Cheadle), and Captain Marvel (Brie Larson) looked at a hologram display that rotated through the faces of people lost during the Blip.Jane's face appeared alongside Peter Parker (Tom Holland), Wong (Benedict Wong), Groot, Drax (Dave Bautista), Doctor Strange (Benedict Cumberbatch), Selvig, and more. This was confirmed in the official script for Endgame. In addition to blaming himself for not killing Thanos, it's likely that Thor heavily blamed himself for Jane's death and disappearance for five years during the Blip. In order to stop their all-powerful sister, Hela (Cate Blanchett), in the third film, Thor and Loki were forced to unleash the fire demon Surtur. While fighting to the death, Surtur destroyed Asgard.After Asgard was destroyed in Thor: Ragnarok and half of their people were killed by Thanos in Avengers: Infinity War, the remaining Asgardians took root in Tonsberg, Norway.Before his death in Thor: Ragnarok, Odin went to Norway and told his sons, Loki and Thor, Asgard is not a place. Never was. This could be Asgard. Asgard is where our people stand.It sounds like Thor paid tribute to his father by picking the country as the new home for his people. At the end of Avengers: Endgame, Thor proclaimed Valkyrie (Tessa Thompson) the ruler of New Asgard, telling her that she's a natural leader. Valkyrie promised to make a lot of changes before bidding Thor farewell.Thor's sister, Hela, shattered it during her first encounter with him and Loki. Thor replaced Mjolnir with an ax forged on Nidavellir called Stormbreaker in 2019's Avengers: Infinity War.Its handle is constructed of Groot's arm and allows Thor to access the Bifrost, which allows him to travel throughout the Nine Realms.Thor also retrieved his hammer when he traveled back in time and brought it to the present-day to fight Thanos (Josh Brolin) in Avengers: Endgame. Don't expect to see that here. Captain America brought it back to its proper timeline at the film's end.Vision (Paul Bettany) wielded it in Avengers: Age of Ultron and Captain America used it during one of the most thrilling moments in Avengers: Endgame.Jane will wield Mjolnir in Thor: Love and Thunder.He was killed by Thanos in Avengers: Infinity War after a failed attempt at the Mad Titan's life.However, there is a variant of Loki running around the multiverse from the current Disney+ series, Loki. This version of Loki only has memories up until he was captured in 2012's The Avengers.It's unlikely we'll see him show up, but since we're seeing a version of Jane with Thor's mighty hammer in Thor: Love and Thunder, there's a chance other familiar characters could show up as well.Thor's mother, Frigga (René Russo) was killed in Thor: The Dark World. His father, Odin, died in Thor: Ragnarok. His friend, Heimdall (Idris Elba), was killed by Thanos in Avengers: Infinity War.His closest friend now is Korg (Taika Waititi) who he met in Thor: Ragnarok on Sakaar. Korg's pal, Miek, stays in New Asgard with Valkyrie.Hela killed Fandral, Hogun, and Volstagg in Thor: Ragnarok. The only one of Thor's friends who remains alive is Lady Sif (Jaimie Alexander) who did not appear in Thor: Ragnarok because of her role in Blindspot.Sif will appear in Thor: Love and Thunder. The last time we saw her in a movie was in an end-credits scene for Thor: The Dark World when Sif was giving the Aether to the Collector (Benicio Del Toro) to protect.Most recently Sif appeared in season one, episode four of Disney+'s Loki in a past memory of the trickster.The last time we saw Thor in Avengers: Endgame, he was out of shape.He sank into a deep depression after originally failing to bring back the people the Mad Titan snapped away, including Jane.Thor received a vital pep talk from Frigga when he traveled back in time to retrieve the reality stone. By the film's end, he was mentally in a better place and focusing on bettering himself and finding what he wants from the world.Thor lost his right eye in a fight with his sister, Hela, on Asgard in Thor: Ragnarok. He wore an eyepatch like his dad until Rocket Racoon gifted him with a replacement eye in Avengers: Infinity War.Thanos sacrificed Gamora (Zoe Saldaña) in Avengers: Infinity War in order to get his hands on the soul stone.An earlier version of her, from before she crossed paths with Peter Quill (Chris Pratt) and formed the Guardians of the Galaxy, was brought into the current MCU timeline in Avengers: Endgame.In a deleted scene, Gamora walked off into the unknown after Tony's death as the rest of the heroes took a knee and honored Stark. Quill, heartbroken over losing his Gamora and never expressing his love for her, will likely be searching for her with the Guardians, in Thor: Love and Thunder.Thor joined the Guardians on their ship, the Benatar, at the end of Avengers: Endgame to travel through space. He tried playfully referring to them as the Asgardians of the Galaxy. Star-Lord clearly wants to try and find Gamora (who may not want to be found). The Guardians have been seen in the film's trailer so we'll see where they wind up.Thor surprised Rocket Raccoon when he starts speaking to Groot in Avengers: Infinity War. Thor tells both of them that Groot's language was taught in his home of Asgard as an elective.Since Thor was last seen traveling with the Guardians of the Galaxy, this is probably worth remembering.
