Real Name-- Thor; once known as Sigurd Jarlson/Donald Blake/Sigmund/Siegfried

Class-- extradimensional (Asgardian)

Occupation-- adventurer / warrior; god of thunder; former doctor and surgeon (as Donald Blake); former construction worker (as Sigurd Jarlson); paramedic / EMT (as Jake Olsen)

Affiliations-- Avengers; member of the Asgard pantheon; son of Odin and Gaea; half-brother of Loki; Sieglinda (Sigmund's sister), Gunthra (Siegfried's wife)

Scale of Operation-- pan-dimensional ; New York City

Powers-- Thor's Asgardian physiology grants him superhuman strength as well as increased resistance to physical attacks, heat, cold, radiation, toxins, aging, and disease. (A special enchantment was placed on Siegfried by the former Valkyrie, Brunnhilde, which provided Siegfried with invulnerability against any form of physical damage, unless he was attacked from behind.)

While fighting Fafnir, Siegfried accidentally tasted some of his blood. This granted Siegfried the ability to read minds and understand and speak with normal animals. Siegfried and Sigmund used a magical sword enchanted by Odin, named Needless. The sword was made of a mystical material. The Tarn Helm was a special helmet possessed by Siegfried, allowing him to make himself look like someone else.

Thor's hammer, Mjolnir, is made of Uru, a mystical metal of indestructible material. No one can forcibly take the hammer away from Thor, unless he wishes it. Mjolnir was further enhanced with magical powers, including the following:

• Upon Striking Mjolnir on the ground or a hard surface, Thor could transform into his mortal form. If Thor was kept away from the hammer for over one minute, he automatically reverted back to his mortal form. When he assumed his mortal form, Mjolnir appeared like a simple wooden cane. Striking the wooden cane against a hard surface reverted Thor back to his immortal form.
• When thrown, whether it hits or not, Mjolnir flies back to the spot from where it was thrown.
• Mjolnir can open an aperture to travel between Earth and Asgard, and even a special pocket dimension where Thor keeps his battle armor and his Belt of Might. By focusing all of Mjolnir's energy, Thor can create a rift in the fabric of the universe, breaking the barriers between dimensions. Thor can determine into which dimension the victims arrive in, travel into random dimensions, and even cross the time-barrier to travel back or forward in time (although this ability was later lost by burning out its enchantment after a trick staged by Immortus and the Space Phantom.)
• Thor can fly at amazing speeds by spinning the hammer around and then throwing it. As it takes off, he grabs hold of the hammer's leather thong and rides behind the hammer.
• Thor gains additional protection against physical, energy, and magical attacks by spinning the hammer in front of himself, creating a shield-like vortex.
• Thor can control the weather through Mjolnir, including producing lightning bolts from the sky or through the hammer. When calling forth lightning, or on command, Mjolnir can release a blinding burst of light . He can create intense winds which can also be used to provide increased protection from projectiles to everyone within Thor's vicinity. This ability can also be used to carry others with him in flight.
• Only a pure and noble person is able to pick up Mjolnir and use it. (Although a machine of sufficient strength can pick up Mjolnir, it cannot use it.) So far, only Odin, Thor, Captain America, Dargo, and Beta Ray Bill have been able to pick up the hammer.
• Thor's special attack of "Unfettered Might" does phenomenal damage and surrounds Mjolnir with a blazing blue aura. Unless he is wearing his special gauntlets, Thor suffers similar damage when he uses this attack.
• Mjolnir can absorb energy and visual psychic attacks, and Thor can then release the energy, in any direction he wants.
• Mjolnir can sense the use of Asgardian magic.
• Thor can draw out the life force of an Asgardian god through Mjolnir, utterly destroying that immortal.

Thor owns two large pet war goats, Tooth-Grinder and Tooth-Gnasher , who pull his war chariot. They have the ability to fly through the air and travel across the ground at fantastic speeds.

History-- Thor is the son of Odin, lord of the gods of Asgard, and Gaea, the eldest goddess of the Earth. Odin wanted a child of Asgard and Earth, which is why he mated with Gaea, the Earth Mother. Gaea gave birth to Thor in a small cave in Norway. A few months later, Odin took the baby to Asgard to be raised by his wife, the Asgardian goddess Frigga. (Thor did not learn that Gaea was his mother until many centuries later.)

The young Thor was raised with Loki, his step-brother. Loki had been the son of the Frost Giant leader Laufey, who had been killed by Odin. Even when they were growing up, Loki was jealous of Thor's powers and popularity. This jealousy grew into an all-consuming hatred.

When Thor was eight years old, Odin sent him to Nidalvellir, the land of the dwarves. Thor was to order the dwarves Brokk and Entiri to create three special items for Odin. One of these items was the Uru hammer called Mjolnir. Loki somehow sabotaged the creation of the hammer so that its handle was made too short.

Odin enchanted the hammer with many powerful magicks, including one that made it impossible for anyone to lift the hammer unless he or she were truly worthy. Odin proclaimed that Mjolnir was intended for Thor's use someday, when he had proven himself worthy to wield it. For the next eight years Thor trained to become a mighty warrior, and he performed many heroic deeds. Odin then presented Mjolnir to him, and declared him to be the greatest warrior of Asgard.

In the Ninth Century, A.D., Thor went to the Earth for the first time. While on Earth he promoted his worship among the Vikings. Later on, the Norsemen and Germanic people would also come to worship Thor and the other Asgardians. While on Earth, Thor encouraged his worshipers to glorify the ways of combat. One day, Thor discovered that some of his Viking worshipers had killed the defenseless inhabitants of a Christian monastery.

Shocked by the fact that some of his more fanatic worshipers were killing innocents in his name, Thor left Earth and cut himself off from his worshipers. Over time, the worship of the gods of Asgard died out.

At one point, Odin had plucked out his eye and threw it in the Well of Wisdom. This eye attained sentience, and grew to a large size. The eye eventually told Thor many stories about himself and Odin, none of which Thor remembered. The eye told Thor that he was not the first Thor, the previous one having been killed during the last Ragnarok while fighting the Midgard Serpent.

The eye also told Thor that Odin had once stripped Thor of his godly essence and placed it in two successive mortal forms. These two incarnations were the two Germanic heroes of legend, Sigmund and his son Siegfried. In these two mortal guises, Thor played an important part in Odin's schemes to regain the powerful cursed Ring of the Nibelung. Sigmund was killed by the warrior Hunding, but Thor was then born as Siegfried.

Siegfried was the son of Sigmund and his lover Sieglinde. Siegfried gained the Ring of the Nibelung after killing the giant Fafnir, who had taken the form of a dragon. (This Fafnir should not be confused with the dragon Fafnir whom Thor has fought several times over the years.) Siegfried also gained the Tarn Helm, which enabled its wearer to magically appear as someone else. During the battle with Fafnir, Siegfried accidentally tasted some of Fafnir's blood, which gave him the ability to understand the speech of animals. It also gave him the ability to read the minds of those nearby. Siegfried then fell in love with Brunnhilde, a Valkyrie who had been stripped of her godly abilities by Odin when she had disobeyed his commands. Using the last of her powers, she enchanted Siegfried so that he could be harmed only by attacks from behind.

Siegfried was eventually killed by Hagen, the son of Albreich, the dwarf who had originally created the Ring and placed a curse on it. Odin then resurrected Siegfried as Thor, but Odin wiped out all memories of his two mortal identities.

As the centuries passed, Thor had many perilous adventures in Asgard. But over time Odin became concerned with his son's headstrong ways and lack of humility. After Thor broke a truce by chasing a monster into the land of the Frost Giants, almost causing a war, Odin decided it was time to teach Thor a lesson. Using the body of a young medical student as a template, Odin created a mortal body for Thor. This mortal body was given a lame leg, and then Thor, stripped of all his power and memories, was sent to Earth to live in the mortal body. He appeared on the campus of the New York State College of Medicine, with a false history and background implanted in his mind. Thus did the life of Donald Blake begin. (It was only until relatively recently that Thor learned that Blake was not a true person.)

Blake applied himself to his studies with great care, and eventually graduated with top honors. Blake soon gained a reputation as a caring family doctor and a brilliant surgeon. He opened a private practice in New York City and hired a nurse named Jane Foster. As time went by, the two began to fall in love.

Odin, knowing that such a love could only end in despair, became worried. About that time, Odin sensed the arrival of an alien space ship in the Solar System. The ship was a scout ship for a main invasion fleet of the alien Kronans. They planned to land on Earth and scout it out for the main fleet. Odin magically altered the ship's course so that it would land in Norway.

Working quickly, Odin placed a compulsion in Blake's mind causing him to suddenly go to Norway for a vacation. While walking along the Norwegian coastline, Blake came upon the Kronan ship and he was discovered by the aliens. Losing his walking cane during his flight from the aliens, Blake took refuge in a cave. A secret door opened up in the back of the cave, and he found a chamber containing nothing but a gnarled wooden walking cane. Unknown to Blake, the chamber was where Thor had been born so many centuries earlier.

Exploring, Blake found that the only other way out was blocked by a huge boulder that he could not budge at all. Frustrated, and scared by the thought of the eventual arrival of the aliens, Blake struck out at the boulder with the wooden cane. Blake was surrounded by a blazing light, and then he found his body transformed into a powerful form. The cane had been transformed into a mighty hammer. Blake instinctively knew that he had become the legendary Thor, even though he still had no memory of his former life.

Thor attacked the Kronans, who fled from his power and strength. Fearing that the whole planet was inhabited by men like Thor, they called off the invasion. For several years, Blake acted as the heroic Thor, and his memories slowly returned. Finally, Odin restored Thor's complete memory and revealed himself.

Thor spent the next few years maintaining his Blake identity and his medical practice. During this time, Thor saved the Earth many times, fighting many super villains. Thor helped found the Avengers, a group to which he still belongs. Later on, he gave up his Blake identity permanently.

The love affair between Thor and Foster continued for many years. It eventually ended when Jane Foster fell in love with a mortal man, Kevin Kincaid. Their engagement was cut short when Foster lay dying. Sif allowed herself to merge with Foster, saving the woman's life. The two were later separated when Foster was sent to a limbo-realm called the Runestaff of the Possessor. Thor, Sif, and Kevin Kincaid were later able to rescue Foster, and the two mortals were then married.

Nick Fury, leader of the espionage agency SHIELD, later helped Thor set up a new identity as Sigurd Jarlson, a construction worker. In this identity, Thor simply pulled back his hair, wore glasses, and dressed like a normal human.

Meanwhile, the demon Surtur caused the destruction of the Burning Galaxy, intending to re-forge the Sword of Doom. The disaster destroyed most of an alien empire, whose survivors fled, pursued by Surtur's demons. The survivor's fleet was discovered by SHIELD, and Nick Fury asked Thor to investigate. Thor faught the alien's guardian, Beta Ray Bill, and during the fight Thor was separated from his hammer, causing him to turn back into Don Blake. Bill picked up the wooden cane (Mjolnir) and struck a wall of the ship. Bill was then transformed into an alien version of Thor, holding Mjolnir.

When Odin then summoned Thor to Asgard, the summons carried Bill to Asgard instead. Odin then summoned Blake to Asgard and transformed him into Thor. Thor and Bill made up, but Bill refused to give up Mjolnir; Bill felt that he had taken it in fair combat, and he needed the hammer to protect his people. Odin ordered a trial by combat, which Bill won. But Bill felt guilty about taking the hammer that had been made especially for Thor, so he returned it to Thor. Odin then ordered a new hammer to be made, with the same enchantments and materials as Thor's. Odin gave this new hammer, Storm Breaker, to Bill. Thor, Beta Ray Bill, and Sif then went to Bill's armada and drove off Surtur's demons. Since then, Bill has helped protect Earth and Asgard from Surtur and other menaces.

Surtur then joined forces with the renegade Dark Elves. The Dark Elves and Surtur's demon army attacked Earth, after opening the Ancient Casket of Winters on Earth. The armies of Asgard and Earth, along with a number of super heroes, drove the invaders back. Meanwhile, Thor, Loki, and Odin protected Asgard from Surtur himself. The three gods mingled their essences, which increased their powers so that they might be able to defeat the demonic fire elemental. During the battle, a great deal of Asgard was destroyed, including the Rainbow Bridge. Surtur and Odin grappled with each other. They two combatants then fell down a huge chasm, which then closed up.

While Beta Ray Bill and the Asgardian army prepared to return home, preparations were made to select a new leader since Odin had disappeared. Lorelei, with the help of Loki, enchanted Thor and caused him to fall in love with her. Loki planned to get Thor to choose him as the new leader. Thor broke free of the enchantment, but the incident had strained Thor's relationship with Sif. Luckily, Sif later realized what had happened and forgave Thor.

Thor, Baldur, and some Asgardians then traveled to Hel, the realm of the Asgardian death goddess, Hela. They went to rescue a number of Earth souls that had been unrightfully taken by Hela. Thor and his allies were able to save the souls, but Thor's face was badly scarred in a fight with Hela herself. Thor returned to Earth and returned the souls to their mortal bodies. While on Earth, Thor also became involved in a conflict with the omnipotent Beyonder. The Beyonder resurrected the leader of the Dark Elves, increased the Elf's powers, and re-named him Kurse. Thor was able to beat Kurse, and send him to Hel, where he caused Hela many problems.

Meanwhile, the gods of Asgard began the Great Althing, to chose a new leader. Thor tried to return to Asgard, but before he could he could, he was turned into a frog by Loki. Thor then helped the frogs of Central Park defeat their enemies, the rats. Thor the frog then regained his hammer, and turned into a frog-like humanoid, the Thunder Frog.

In Asgard, Harokin, an Asgard warrior, pretended to be Thor. This deception postponed Loki's attempt to become the new leader of Asgard. Thor arrived in time and secretly captured Loki before the evil god revealed the deception. Meanwhile, Volstagg discovered Surtur's sword. Loki had hidden the sword and was using a machine to drain magical energy from the sword. The magical energy had provided Loki with the power to transform Thor into a frog. Volstagg destroyed the machine, which freed Thor from the spell and transformed him back into his normal form. Thor then talked the Asgardians into making Baldur their new leader.

Hela, who had guessed that Thor had sent Kurse to Hel, cursed Thor that so his bones became as brittle as a normal human's. She also cursed him so that he could not die from his injuries. Thor grew a beard to conceal the facial scars caused by Hela, and donned a suit of battle armor to support his fragile body. Despite the curse, Thor was able to kill the Midgard Serpent. Thor survived the battle, even though the prophecies said that he should die in the fight too. He survived partially thanks to Hela's curse. Unfortunately, his body was completely broken and battered, still alive, but unable to move and in a great deal of pain. Loki sent the Destroyer armor to torment Thor, but instead Thor was able to send his spirit into the Destroyer armor and command this ultimate weapon.

Thor then traveled to Hel, planning to force Hela to free him of the curse. Hela was stunned by his new form, as the Thor Destroyer set about obliterating Hel. Thor pretended that the basic soul of the Destroyer had taken over, which meant that he acted like he was going to destroy Hela and Hel. The desperate Hela had no choice but to return Thor to his original body, and in return, release him from her curse. Thor made Hela promise never to take a soul she was not entitled to by the ancient laws, before he agreed to return his soul to his original body. The frightened Hela agreed and sent Thor back to Asgard. Thor arrived in time to save Asgard from an invasion by the Frost Giants, who were secretly backed by Loki.

Thor and Asgard next became embroiled in a battle with the Egyptian god of death, Seth. While Seth and his armies attacked Asgard directly, Thor and some of his friends attacked Seth's Black Pyramid, the source of Seth's powers. Thor discovered that Seth's powers were backed by the captured Bes, the Egyptian god of luck. Thor also found and rescued the lost Odin from the pyramid. Odin had been captured by Seth after separating from Surtur during the long fall and battle with Surtur.

Odin and Thor's allies returned to Asgard to stand in the final battle against Seth and his army. Odin granted Thor a portion of his power and left him behind in Seth's dimension, to battle the arriving Surtur. As Surtur and Thor fought, the nearby Black Pyramid was destroyed. The resulting energy backlash thrust the grappling foes through time and space. Meanwhile, Odin led the surviving Asgardians in a desperate battle with Seth and his army. While Odin was busy fighting Seth, Hogun killed the death god with the Black Knight, whose body had been cursed to become a living magical blade. Thor and Surtur then arrived in Asgard, and Thor managed to stun Surtur. Odin then absorbed Surtur's life essences, imprisoning the demon within his own body.

After the battle, Thor returned to his life on Earth. Unfortunately, it became harder and harder to communicate and travel between Earth and Asgard. Asgard drifted into the Negative Zone and was apparently stuck there. Odin imbued Mjolnir with the ability to contact Asgard one last time.

On Earth, Thor was having many problems of his own. Unknown to him, his body had been infused with a portion of his evil step-brother's power. This had happened when Thor, Loki, and Odin had mingled their essences during Surtur's first attack on Asgard. This caused Thor to have unexplained moments of weakness during stressful situations. Thor also became friends with the architect Eric Masterson and Masterson's son, Kevin.

During this time, Odin would enter his Odin-sleep, and noble Heimdall would take over as Asgard's ruler during this time. Some time later, the mysterious Mongoose attacked Thor several times, trying to gain a cell sample from the god of thunder. Finally, Mongoose kidnapped Eric Masterson and left a trail that led Thor to Wundagore, the High Evolutionary's home. Thor saved Masterson and the two learned from the High Evolutionary's New Men that the god Hercules and the High Evolutionary had been missing after evolving to a higher state. Masterson accompanied Thor and helped him free Hercules and the High Evolutionary from Celestials holding them prisoner in the Black Galaxy. They returned to Earth, while the High Evolutionary turned Wundagore into a spaceship and headed for the Black Galaxy. Unknown to Thor, a cell sample was obtained from him before Wundagore left.

Hercules, Thor, and Masterson were then viciously attacked by Mongoose using weapons he had stolen from Wundagore. Mongoose almost killed Thor using a powerful energy beam. Masterson took a killing blow for Thor, giving Thor and Hercules a chance to defeat Mongoose. Unfortunately, Masterson was dying from his wounds. Thor used his hammer to contact Odin, and begged Odin to spare Masterson at any cost. Odin reluctantly agreed, merging Thor and Masterson together, body and soul. They began to share the same life, much as Blake and Thor had, although the two were separate beings.

While Thor and Masterson dealt with their new condition, more problems arose. Masterson's private life suffered from his time away as Thor. Masterson eventually gave up custody of his son, Kevin, to his ex-wife Marcy. While Eric thought it was best, his secretary, Susan Austin, disagreed, as she had come to love Eric and Kevin.

Thor's spells of weakness came more often, almost causing his death several times. Thor asked for help from Doctor Strange, who entered Thor's mind. Thor accompanied Dr. Strange on this journey. Inside Thor's mind, they discovered an evil version of Thor, whom the real Thor was able to defeat. They then discovered that it was actually a portion of Loki's evil essence.

Thor and his friends became plagued by more problems, which Thor soon found were caused by Loki. Thor and Masterson were briefly separated by a Celestial while they were involved in the birth of a new Celestial in the Black Galaxy.

After this they journeyed to Asgard with the help of Sif. At the time, Asgard was the scene of a tremendous battle between the fire elemental Surtur and the ice elemental Ymir. This battle signaled Ragnarok, the end of the universe. Following Odin's plan, Thor recovered Surtur's sword from the Sea of Eternal Night. He then confronted the two elementals. Unfortunately, he was weakened by his separation from Masterson, and was easily stopped by the two creatures. Masterson willingly merged with Thor again, even though it meant giving up part of his life. While Ymir and Surtur fought over the sword that would light the Eternal Flame of Destruction, Thor opened a dimensional rift that sucked them both into the Sea of Eternal Night, placing them both in suspended animation forever.

Thor then returned to Earth and found himself once more plagued by Loki and his evil designs. Loki kidnapped Kevin, Masterson's son, and then stole the Wrecker's Asgardian-given powers. More powerful than ever before, Loki attacked Thor when he came to rescue Kevin. After Kevin was taken out of harm's way, Thor beat Loki but could not bring himself to kill his step-brother. The arrogant Loki surrendered and then shot a magical blast at Kevin and Marcy on the streets below. The Enchantress, Loki's ally, feared Odin's wrath for her aid to Loki and she mind-controlled Susan Austin to make her take the blast. Susan saved Marcy and Kevin, but she died from the blast.

The enraged Thor drew out all of Loki's life force with his hammer, destroying the evil god forever. This broke Odin's sacred rule forbidding Asgardian gods to kill each other.

Foreseeing this, Loki had previously entered into an alliance with the demon Mephisto. As Loki perished, his own soul displaced that of the sleeping Odin to Mephisto's realm. Then Loki, who now inhabited Odin's body, awoke and declared to Heimdall that Thor should be banished. Heimdall argued against it, but was compelled to obey. Thor begged that Masterson be spared and that Earth not be left unprotected. Heimdall agreed, and then Thor's soul was eternally banished.

On Earth, Masterson soon discovered that he could now assume Thor's mighty form by striking his cane on a hard surface. Masterson took on Thor's heroic identity, including his membership in the Avengers, and engaged in many heroic endeavors.

Eventually, Odin awakened from his Odin-sleep, but remained controlled by Loki. He banished Heimdall and began a reign full of rash judgements and actions, including the persecution of the Warriors Three. Mephisto then betrayed Loki, giving the soul of Odin over to Masterson/Thor, Sif, and Balder the Brave. Masterson promptly battled Loki, who was slowly absorbing Odin's power. Defeated by Loki and left near-death, Masterson was saved by Balder, Sif and the Warriors Three, and together the heroes released Odin, who went on to defeat Loki and thus regain his own body. Loki, for his troubles, was then claimed by Mephisto, who claimed this as his true goal all along. Odin then went on to reveal that Thor's soul wasn't truly banished, but resided within Masterson's own mind. Masterson freed the thunder god, leaving them separate beings once more. However, Masterson was still able to transform into a version of Thor, and he created a separate heroic identity as Thunderstrike.

However, the recent events had left Thor mentally unbalanced and vulnerable. A beautiful Valkrye started to appear before him and convinced Thor to reject his heroic nature and start looking out for himself. (This Valkyre was really only a figment of Thor's fractured mind.) During this time the being known as the Goddess convinced the unbalanced Thor to join her cause to forcibly bring order to the galaxy in the so-called "Infinity Crusade." Although Thor was released from this mania when the Goddess was defeated, he nevertheless remained unstable.

Sif and Beta Ray Bill began a quest to find a cure for Thor, whom Sif feared was loosing himself to the incurable Warrior's Madness. Before Thor could kill Sif and Bill, the alien Silver Surfer intervened as well as Adam Warlock and the Infinity Watch, but to no avail. Infinity Watch member Moondragon attempted to cure Thor with her Mind Gem, but succeeded only in making the Valkrye a physical being. Thor then stole the Power Gem from Drax the Destroyer, making himself virtually unstoppable, and retreated to an abandoned part of Asgard's realm. The assembled heroes, along with Doctor Strange, summoned the mad Titan, Thanos, as the only one to stop Thor, and Thanos eventually managed to restrain the mad Thor in a block of pure force. Together, the entire group attempted to excise Thor's mania. However, they failed and nearly became lost in madness themselves, returning to reality only when Thanos asserted his willpower. The resulting backlash caused the Valkrye to vanish into Thor's mind once more. The group then decided the only way to cure Thor was to take him to Odin.

The arrival of the group was misconstrued as an act of aggression, and Odin ordered his Asgardians to attack before the truth became known. Odin entered Thor's mind in an attempt to cure Thor, and with Doctor Strange and Warlock, journeyed across Thor's mental landscape. There, Odin found his son chained unto a mountain. There Odin realized that by continually attempting to teach his headstrong son humility, he had driven Thor to madness by splitting off his power among others such as Beta Ray Bill and Eric Masterson. Odin freed his son, and was faced with the Valkrye. Thor himself fought his own madness and destroyed the Valkyrie, thus curing his madness.

Afterwards, Thor dreamed of Ragnarok and grew angry at his father's past efforts to discipline him. Deciding to leave Asgard, Thor allied with the High Evolutionary and his newly created godlike beings, the Godpack, becoming the group's leader. Soon, however, Thor returned to Asgard to find another Thor taking his place there. This Thor was a man named Roger Norvell, who had once before held the mantle of the thunder god and had died defending the realm. After Thor had departed, Odin decided that should Ragnarok come, he needed Thor at his side. Thus, Odin journeyed inside the Hall of Valhalla to find Roger Norvell. Then, Odin bestowed upon him the power of Thor, and even gave him a new version of Mjolnir. Then, Odin declared Roger "Red" Norvell his own son and thus disowned the true Thor. In the aftermath of Odin's latest decision, Odin told Thor the truth about Donald Blake, leading to a split with his father.

During this time, others possessing the powers of Thor fell ill or died. This culminated in the fall of Asgard, and the banishment of its Gods to Earth. Before Thor could help restore Asgard and return its Gods to their immortal status, he fell in battle to the creature known as Onslaught. Thor vanished, along with other heroes such as the Avengers. But, like them, he has appeared again in another dimension and was eventually returned to our own universe.

When Thor returned, he found the Golden Realm overtaken by an overwhelming evil force. A group of Dark Gods had conquered Asgard ( following the return of the Asgardians from their banishment ), and now held Odin, along with the remaining Asgardians, captive. During this time, the Asgardian robot known as the Destroyer began a rampage on Earth. Thor, along with the Avengers battled the animated suit of armor. Over the course of the battle, Thor's obsessive desire to stop the Destroyer resulted in the death of a mortal man named Jake Olsen. The Avengers fell, and Thor battled the armor alone until he was defeated and left near death. A mysterious being named Marnot appeared to Thor and offered him a chance to return to the land of the living if he would take the place of the mortal Jake Olsen. Thor accepted, and returned to battle the Destroyer, ultimately banishing it to another dimension. As with his bargain with Marnot, Thor tried to continue the life of his alter ego of Jake Olsen.

Later still, Thor and Hercules journeyed to Olympus to find it in ruins. There Thor found that the Olympians had been attacked by the Dark Gods, masquerading as the Asgardians. Thor became even more determined to defeat the Dark Gods, and eventually discovered that they had previously invaded centuries before, during Thor's childhood, but were defeated and banished. After a protracted battle, the Dark Gods were eventually defeated and both Asgard and Olympus was freed from their rule. Then, Marnot was revealed to be Hescamar, one of Odin's ravens. After the Dark Gods had been defeated the first time, Odin had prepared for their return by casting a spell on Hescamar that would transform the raven into a powerful being named Marnot should Asgard fall. This being was then to find a way to defeat the Dark Gods, a mission Marnot eventually fulfilled by aiding Thor. Afterwards, Thor elected to remain on Earth in his obligation of the mortal guise of Jake Olsen.

Among his subsequent adventures, Thor rescued Tarene, the cosmic being known as the Designate, who would later take on the identity of Thor Girl out of admiration of Thor. Thor and Thor Girl battled the alien Gladiator, who vowed to destroy Thor in a preemptive strike to prevent a terrible horror that he believed Thor would inflict in the future. As such, Thor was unable to defend Asgard against an army of Asgardian trolls that overwhelmed the city's defenses. Odin was forced to defeat the trolls, and he confronted Thor, disappointed in his son's inability to remain loyal to Asgard. As punishment, Odin stripped Thor of his immortality and left him on Earth.

Shortly afterward, Loki brought the Destroyer back to Earth, animating it with the soul of Tarene. Ultimately, the Destroyer was thwarted and Tarene was restored, but during the battle, Thor was severely wounded. Dr. Jane Foster could heal Jake Olsen's wounds but remained unable to treat Thor's. Odin brought Thor to Asgard and physically separated Thor from his alter ego to allow Thor to heal and to allow Jake Olsen to return to his life on Earth.

When Surtur appeared on Earth, an assemblage of Asgardian heroes and their allies confronted the demon and his hordes. Tarene used her powers to restore Thor to full health, joining with Odin and the Asgardian warriors against Surtur. In the end, Odin tapped into both Thor and Tarene's powers to deliver a fatal blow against Surtur, sacrificing himself in the process.

In mourning the loss of his father, Thor initially refused to take Odin's place, until a discussion with Jake Olsen convinced Thor to assume the responsibilities of the new monarch of Asgard. He also left Tarene to take his place as a crime-fighting super-hero on Earth, under the guidance of Jake Olsen.

When Thor Girl was nearly destroyed in a battle with the criminal Grey Gargoyle, Jake Olsen sought help from the Enchantress and was transformed into a version of Thor, a transformation that robs Thor in Asgard of some of his power. At the same time, Desak, the self-styled destroyer of gods, confronts the Olsen-Thor, nearly killing him. Thor managed to return from Asgard to defeat Desak, with the help of the Executioner's mystic axe, given to Thor by the Enchantress. However, Thor seemed to be influenced by a corruption of the Odin-power he now possessed coupled with the influence of the Executioner's axe.

Thor's preoccupation with Earth made many Asgardians lose faith in Thor as their new lord. Although Thor vowed not let his Earthly concerns interfere with his royal duties, he moved Asgard into the Earth's plane of existence. Thor confronted the President of the United States, telling him how he intends to provide a moral example for mortals to follow.

Note: Another version of Thor exists in 26th-century Earth, in the alternate time line inhabited by the Guardians of the Galaxy. By this time, the governments of Earth had fallen and the corporations had taken over.

A rebellious cult of workers hoped to someday be free of the tyrannical rule of the corporations. They tried to find someone who could lift a holy weapon (Mjolnir). Government forces attacked a cult meeting one night, causing a skeptical cultist, Dargo Kyto, to reach for the hammer. To his amazement, Dargo found himself transformed into a futuristic version of Thor.

This new Thor destroyed the evil corporation, which was secretly backed by Loki. During the battle, a troll revealed that the real Thor had been held for centuries in some sort of prison dimension (Loki wanted to make sure that Mjolnir didn't get back to its rightful owner).

Dargo attempted to open a mystical gateway and throw the hammer through, hoping the weapon would find its way back to its owner. Some time later, the hammer returned to Dargo. Dargo has since served as the Thor of his time period.
