• Hermod; god of speed based on the deityHermóðr, is Thor's half brother by Odin and Frigga. Hermod is employed as Odin's messenger due to his great speed.

• Mimir; based onMímir, is Odin's uncle and guardian of the well of wisdom. Mimir was beheaded during theÆsir–Vanir War and his living head was brought to Odin, who turned it into fire. In this state Mimir was given the power of prophecy and Odin made him his advisor.^[17] Odin sacrificed his right eye to Mimir's well for the wisdom to forestall ragnarök.^[18] Later Thor sacrifices both his eyes for insight on how to end the ragnarök cycle.^[19]
• Odin; the all-father, ruler of Asgard based on the deityOdin, is Thor's father. Odin with his brothers Vili and Ve slew the frost giant Ymir, who he was descended from, and with his body created the heavens and earth.

Their deaths also granted Odin the "Odinforce".^[20] Odin later fights Surtur on Earth, where both are killed.^[21] The Odinforce then passes to Thor who becomes lord of Asgard.

Thor regularly interacts with other Marvel superheroes as a member of the Avengers. A few, however, have marked a presence in the core Thor titles:

• Beta Ray Bill; An alien from the Korbonite race, the warrior Bill proved worthy to lift Mjolnir. He beat Thor in a battle for the right to wield the hammer, but when he decided to let the thunder god keep it after all, he was awarded the mystical hammer Stormbreaker by Odin as a reward.^[28] Since receiving Stormbreaker, Bill has been a loyal ally of Thor and the Asgardians, especially Sif whom he has developed a particularly close relationship.^[29] Bill even served as a member of the briefly lived Thor Corps.^[30] During Ragnarök Bill came to the aid of Asgard and when Thor left to find a means to end the cycle once and for all, he left Bill in charge of the Asgardian forces.^[31]
• Captain America; the honorary co-founder of the Avengers has developed a close bond with Thor over the years as a brother in arms. This bond was further strengthened when Cap proved worthy to lift Mjolnir.^[32] When Loki's forces overran Asgard during Ragnarök, Thor sought the aid of Captain America and Iron Man who were able to help the Asgardians regroup.^[33] Later Thor returns after the events of Ragnarök only to discover that Captain America had been assassinated and visits his grave. There he encounters Cap's spirit which is not able rest due to the mass media politicizing his death. Thor honors him by flying into space and disrupting every satellite signal for sixty seconds thus granting him a moment of peace.^[34]
• Hercules; the son ofZeus based on the heroHeracles from Greek mythology, is both the longtime friend and rival of Thor. Their friendly rivalry begins after Thor (without his powers) is beaten by Hercules but then rescues him fromHades.^[35] The two brawl again in limited seriesThor: Blood Oath and later inThe Incredible Hercules with Hercules disguised as Thor and Thor disguised as Hercules.^[36][37] Hercules joins the Avengers himself after assisting them in reserve capacity for some time.^[38]
• Hulk; a co-founder of the Avengers shares one of the most significant rivalries in theMarvel Universe with Thor. The rivalry begins after the Hulk leaves the Avengers and allies withNamor as the latter bids to rule over humanity. In the midst of the ensuing battle between the Avengers and the Hulk and Namor, Odin grants Thor's request to be able to retain his powers without his hammer for five minutes so that he might test his strength against the Hulk. The two fight to a stalemate before the tunnel they are fighting in collapses and are forced to separate.^[39] The two battle again inThe Incredible Hulk #255 (1968),The Defenders #10 (1973),Thor #385 (1987),Heroes Reborn #2 (1996),The Avengers (vol. 2) #5 (1997),The Incredible Hulk Annual 2001 andOnslaught Reborn #2 (2006). Despite this Thor respects the Hulk and they eventually become friends after Thor aids Hulk in defeating theRed Hulk.^[40] The rivalry comes to a head during the events ofFear Itself, in which Thor fights Hulk, who has been turned into Nul: Breaker of Worlds. During their battle Thor states that he has always thought of Hulk as "a pain in the ass." Once the battle nears a conclusion Thor says to Hulk "I cannot beat you, you know. And I never could," to bait the Hulk into moving in for the takedown. Thor then uses Mjolnir to knock Hulk into outerspace.^[41]
• Iron Man; a co-founder of the Avengers like Captain America has developed a friendship with Thor. Iron Man with Captain America even aided Asgard during Ragnarök.^[33] However this friendship was strained when Thor returns and learns that Iron Man and others used hisDNA to build aclone to fight in theCivil War.^[42] Despite this Thor comes to Iron Man's aid when he is left in a vegetative state after Iron Man is savagely beaten byNorman Osborn.^[43]
• Silver Surfer; a former herald ofGalactus became an ally of Thor after Loki attempted to use the Surfer as a tool to defeat his brother. Convinced Thor is evil by Loki, the Surfer is transported to Asgard and challenges Thor to a fight. However the Surfer realizes that he has been deceived when he sees Thor's honor in battle.^[44] Later the Surfer along withAdam Warlock help cure Thor of his "warrior's madness" when he becomes enraged by a valkyrie.^[45] Silver Surfer and Thor would also team up to defeat the villain Millennius after he creates a rift between Earth and Asgard in an attempt to escape his dimensional prison.^[46]
• Thor Girl; an alien destined to become the Designate, a being who will help evolve sentient beings to the next level of existence becomes an ally and admirer of Thor after he helps defeatThanos who destroyed her home world.^[47] She then comes to Earth, transforms herself into an Asgardian and takes the name Thor Girl.^[48] Thor Girl nearly loses all of her powers in battle against Surtur that also results in Odin's death.^[49] Thor Girl also played an important role in ending an alternate future where Thor rules Asgard and Earth with an iron fist known as 'The Reigning'.^[50]
• Thunderstrike; an architect by the name of Eric Masterson is initially bonded with Thor after the Thunder God is punished for apparently killing Loki.^[51] Masterson carries the mantle of Thor for several years, continuing Thor's dual roles as a member of the Avengers and protector of Midgard. Thor is eventually freed,^[52] and in gratitude for his services, Odin provides Masterson with an enchanted mace, which he uses under the alias ofThunderstrike.^[53] Masterson also served on the Thor Corps with Beta Ray Bill and a future incarnation of Thor named Dargo Ktor.^[54] Later Thunderstrike succumbs to the curse of theBloodaxe, which he used to defeatSeth but dies after finally being able to rid himself of the curse.^[55]
• Storm; a member of theX-Men, when she along with theNew Mutants were captured by Loki,^[56] he gave her a replica of Mjolnir called Stormcaster in order to discredit Thor,^[57] however, this backfired.^[58][59]

Thor has an extensive rogue's gallery, some of his most memorable villains include;Loki,the Enchantress,Malekith,Hela,Mangog,Surtur, andthe Wrecking Crew.

Thor has had several notable romances throughout his long history:

• Sif, a warrior based on the deitySif, is one of Thor's main love interests. However, Thor's draw to Earth has been a constant distraction. Sif did for a time try to live a mortal life on Earth, but found it to be mundane and returned to Asgard. Furthermore, their relationship has suffered from numerous interruptions by other women, particularly Jane Foster, the Enchantress, and Lorelei. Sif and Thor, however, have always found a way to rekindle their romance. After the events of Ragnarok, Thor was able to restore every Asgardian with the exception of Sif, whose spirit was trapped inside the body of a dying elderly woman. Thor eventually was able to restore Sif as well, just before the elderly woman died.^[60]
• Jane Foster, a nurse, was involved in a love triangle with Thor and Dr. Donald Blake, not knowing they were one. Thor eventually reveals the truth to Jane and takes her to Asgard where she is granted immortality and status as a goddess. Disapproving, Odin strips Jane of her newly acquired powers, returns her to Earth without memories of Asgard, where she marries Dr. Keith Kinkaid and has a child. Much later, Dr. Donald Blake returns to Earth after emerging from the void of nonexistence and encounters Jane, who has since divorced Dr. Kinkaid. After a rocky exchange, the two agree to go on a date.^[61]
• The Enchantress is one of Thor's most notable antagonists and lovers. Since her introduction, Amora, The Enchantress, has often tried to use her magic to seduce Thor and eliminate her competition for Thor's affections. However, Thor did form a willing romance with Amora during a vulnerable state when Odin abandoned him without his powers on Earth.^[62] This relationship reached its pinnacle when Thor assumed the throne of Asgard and took the Enchantress as his bride. Amora helped Thor create a dark future in which they ruled Asgard and Earth with an iron fist and even had a child,Magni. However, this was all undone when Thor traveled back in time to prevent this future from occurring.^[63]
• Shawna Lynde, a fellow doctor of Donald Blake's. Both had supposedly graduated from medical school together. Shawna had an open crush on Blake, but was unaware of his connection as Thor. She too was briefly caught in a love triangle between herself Blake and Sif, however she was unaware of Sif's identity and thought that she was Blake's cousin 'Sybil'.^[64] When Donald Blake ceased to exist, she became concerned, but had her memory wiped by Fandral. He reveals that even though she won't remember Blake in her waking life, she would still feel his presence in her dreams.^[65]
• Lorelei, like her sister Amora, the Enchantress, has also used magic to gain the affections of Thor. Loki persuaded Lorelei into giving Thor an elixir that would cause him to fall in love with her. Loki hoped Lorelei could then use her influence over Thor to gain his support for Loki's bid for the throne of Asgard. However, the Enchantress jealously cast a spell of her own, which caused Lorelei to fall in love with Loki.Heimdall in turn used this to expose Thor to their plot.^[66]
• Brunnhilde thevalkyrie attempted (to no avail) to save the life of Thor, who was incarnated asSigmund against Odin's wishes. Brunnhildewas, however, able to keep Sigmund's pregnant wife, Sieglinde, from harm. As punishment, Odin removed Brunnhilde's powers and cast her into a deep sleep. Brunnhilde is eventually awakened by Thor, who reincarnated asSiegfried, the son of Sigmund and Sieglinde. Brunnhilde and Siegfried become lovers, but Siegfried, under the influence of magic, betrays her. When Siegfried is killed, Brunnhilde, who is still in love with him, jumps into his blazing funeral pyre. Odin, so moved by these events, fully restores both Brunnhilde and Thor but wipes their memories.^[67]
• She-Hulk, during the battle against the DarkCelestials, Jennifer Walters became romantically involved with Thor,^[68] but was concerned that Thor was only interested in her Hulk persona, until they had a heart-to-heart moment.^[69]

• Dr. Donald Blake; a handicapped surgeon, is Thor's most significant mortal host. Blake discovered that he had merged with Thor when he found Mjolnir in the form of a stick while vacationing in Norway.^[70] Blake maintained these dual roles for some time until Odin removed Thor from Blake which unknowingly sent Blake into the void of nonexistence. However, when the Asgardians seemingly perished during Ragnarok, Blake was suddenly transported back to Earth. Blake then finds Mjolnir and returns to the void to awaken Thor so that they may remerge together.^[71]
• Frey; based on the deityFreyr, helped constructValhalla. After Valhalla was damaged in an attack Odin bribed two giants to restore it by promising to give themIdunn. Loki promised to Odin that he would keep Idunn safe and the debt would never be paid but Loki handed Idunn over to the giants anyway.^[72] Frey and Thor fought the two giants but were forced to stand down when Odin revealed his promise to the giants. However the giants did agree to relinquish Idunn in exchange for the ring of Nibelung.^[73]
• Freya; goddess of fertility based on the deityFreyja, is the sister of Frey. When Thor's hammer, Mjolnir was stolen by the giant, Thyrm, he offered its return in exchange for the hand of Freya in marriage.

Idunn was offered as payment to two giants for restoring the walls of Valhalla but the giants settled for the ring of Nibelung.^[77] Idunn was captured again by Loki and Tyr who wanted to feed her golden apples to the Midgard Serpent as part of their plan to lay siege to Asgard. She was later rescued by Balder and the Warriors Three while her apples were retrieved by Thor.^[78]

Magni then sought the counsel of Sif, found Mjolnir and confronted his father, Thor. During the confrontation, Asgard was attacked byDesak and Magni was critically injured in the battle. This act showed Thor the error of his ways and set back in time to prevent this future from occurring.^[80]
• Jake Olson; a paramedic that was bonded with Thor for a time. Olson was slain during a battle between the Avengers including Thor and a Dark Gods controlledDestroyer.

• Sigyn; goddess of fidelity based on the deitySigyn, is married to Loki. Sigyn's beauty caught the eye of Loki but she was already engaged to another. Before Sigyn's marriage Loki jealously killed her fiancé and used a spell to take his form during the ceremony. Loki revealed his true identity but Sigyn remained with him due to Asgardian law. After Balder's death, Loki is punished by being chained to rock where a snake constantly drips poison on his face. Sigyn being ever loyal comes to Loki's aid by catching the poison in a bowl. However Sigyn must periodically leave to empty the bowl and during the time she is gone the poison drips in Loki's eye. Loki abandons her for this after he is freed.^[84]
• Thialfi; based on mythological figureÞjálfi, was one of Thor's advisors during the time known asThe Reigning. Thialfi was born during theViking Age and his parents were killed by Viking marauders.
