Host to Thor

Dr. Donald Blake was created by Odin to be the host for his son Thor.[4] He later gained a life and sentience of his own, separate from Thor's.

Thor the God of Thunder

Odin decided that it was time Thor learned humility. Odin had Thor surrender his hammer to him, and then sent him to Earth in the mortal guise of a crippled young Harvard University medical student named Donald Blake, stripped of his memory (again) of his true identity. As Blake, Thor learned the value of humble perseverance in dealing with his injured leg, and he came to care for the sick and dying, first as a medical student, and later as a successful physician. After leaving medical school, Blake opened a private practice in New York, and quickly gained renown as a great surgeon.[4]

After Thor had spent ten years in the role of Blake, Odin planted within Blake's mind the suggestion to take a vacation in Norway. There, Blake encountered a party of alien Kronans, also known as the Stone Men from Saturn. Blake fled from the Kronans into a cavern, the very same one that had served as Thor's birthplace millennia ago, where Odin had left Thor's hammer in the enchanted form of a wooden cane. Trapped in the cavern by a great boulder, Blake struck the boulder with the cane in frustrated anger, and was transformed back into his true godly form of Thor. As Thor, he escaped the cavern and drove off the Kronans.[3]

At first Thor still had no memory of his past life as an Asgardian god, although as months passed, more of his memories returned. Finally, a few years later, Odin revealed to him the false nature of the Blake identity and the reason for it.[4]

Thor maintained his Blake identity on Earth and continued his medical practice. Part of his affinity for Earth was his subconscious realization that his maternal heritage was on this world. The other part was simply his love for humanity and his need to experience those things that only mortals could know. Thor came to divide his time between Earth and Asgard, and does so to this day.[citation needed]

For years, Thor was in love with Jane Foster, who worked as a nurse for Blake. Odin disapproved of Thor's love for this mortal, but eventually the romance between Thor and Foster came to an end, and Thor renewed his past relationship with Sif. Thor was a founding member of the team of superhuman champions known as the Avengers, and continued to serve with the team from time to time until the present. As such, Blake was often also involved in their adventures.[citation needed]

Thor eventually gave up his identity as Don Blake. In fact, Odin transferred the enchantment enabling Thor to change into mortal form and back from Mjolnir to that of his ally and alien counterpart, Beta Ray Bill. With the aid of Nick Fury, Public Director of S.H.I.E.L.D., Thor adopted a new "secret identity," that of construction worker, Sigurd Jarlson. In this identity, Thor did not actually become mortal in his Jarlson identity; he simply dressed as a normal contemporary Earthman and wore glasses.[citation needed]


When Thor returned to life after Ragnarök, it was Donald Blake who resurrected Thor by reclaiming Mjolnir, becoming Thor and bringing Asgard to Broxton, Oklahoma.[5][6]

Shattered Heroes

After Thor's death at the hands of the Serpent, Donald Blake somehow became a separate entity from Thor again. When the Odinson returned to life, Blake was distressed to discover that his life had never happened.

Later, he asked Enchantress to help him gain his divine power back. She managed to give him a Golden Apple of Idunn, to which he reacted violently. Enchantress used this opportunity to decapitate Blake and, through her magic, give life to a construct god she named "the Keep".[7]

Blake's happily ever after.

When they arrived in Asgardia, Thor was already waiting for them. Blake's head confronted him and after Thor understood and dispatched the Keep, Blake was given a new life within a dream crafted by the Mares.[8]

Shadow of Thunder

When wondering through his neighborhood oblivious to everything that happened during his absence, the Midgard Serpent arrived and revealed the truth about his fake life, in an attempt to make Blake his pawn against Thor. However, Blake attacked the serpent and took his power which combined with his own making him more powerful than ever.[9] After realizing that his life was nothing but a simulacrum, Blake begged for Thor to help him. However, when Thor never responded, Blake was disillusioned by the god of thunder and went mad, killing the simulations of people within his dreamscape, including the Midgard Serpent. When Thor swapped places with Blake in an attempt to fix Mjolnir, Blake was finally free of his false life. Blake then faced off against Loki, easily defeating him, while stating that he would never be Thor ever again, breaking the cane he used to switch into Thor.[10] Blake then went on to defeat Sif, Beta Ray Bill, the Warriors Three and many Asgardian soldiers, afterwards pledging to kill all who had carried the mantle of Thor,[9] starting with Roger "Red" Norvell by mutilating him, before proceeding to attack Throg.[11]

Throg was aided in his fight against Blake by the Inhuman dog Lockjaw and were able to defeat Blake. Throg and Lockjaw then took Blake to the Sanctum Sanctorum to be interrogated by Doctor Strange. However, Blake easily overpowered Strange and stole the Asgardian power he used to fight Loki when he took the title of Sorcerer Supreme from him. Blake also discovered where Strange got that power: Yggdrasil. After defeating Strange, Throg, and Lockjaw, Blake went to Yggdrasil and began cutting it down with Jarnbjorn.[12]


Odin-Force: As a construct of Odin, Donald contains the Odinforce, and when it interacted with Jormungand's own power, it became amplified and corrupted, resulting:[9]

  • Superhuman Strength: Don has enough strength to take on Asgard's forces, seriously wound the world serpent, defeat Loki, the Warriors Three and Sif effortlessly.[9]
  • Asgardian Magic: Able to operate the Bifrost to send the Asgardians realms away using Hofund, as well as remove Beta Ray Bill's worthiness and power.
    • Asgardian Magic Absorption: He is capable of absorbing "Odin-magic" from a variety of sources, including the Midgard Serpent,[10] Beta Ray Bill's enchantments,[9] the powers of various Thors,[11] and Asgardian magic used by Doctor Strange before trying to take it directly from the lifeblood of Yggdrasill itself.[12]
  • Superhuman Durability: Blake was able to withstand Throg's lightning attacks.[11]


Medical knowledge: Considered to be one of the best doctors and surgeons in the country.[4]

Blake also has all the knowledge and skills that Thor has, claiming whatever Thor can do, he can do better. This was shown when he defeated Sif, the Warriors Three, and many Asgardian soldiers.[9]

  • The transformation from the Mighty Thor to Don Blake is capricious. The transformation from Blake to Thor creates a bright light and appears to be impactful. The transformation has caused a Storm Giant to lose his grip on the Thunder god[13] and has freed Blake/Thor from rubble that the Thunder god himself was unable to move.[14] However, the transformation has also taken place in Don Blake's office with individuals outside the room not cognizant of this mystical event.[15]
  • The emanations from the transformation from Don Blake to Thor (and vice versa) has also been portrayed as substantial. After months/years of the mystical transformation, the residual energy was enough to power Mercurio's Dimensional Oscillator and open a channel to his 4th Dimension.[16]
  • Don Blake's origins changed frequently over the years:
    • Beginning with Journey into Mystery #83, Don Blake was implicitly presented as a normal doctor who found the hammer of Thor and began channeling the Thunder God (for lack of a better word) as they shared a single life and experiences.
    • In Thor #159, Odin revealed that Don Blake was merely a magical construct, specifically engineered to present Thor with the opportunity to learn the lesson of humility Odin sought to teach him. Blake had no past before Odin willed him into being to be inhabited by Thor.
    • In Thor Annual #11, while reviewing the saga of Thor, the Norns witnessed Odin's statement, made when he had exiled Thor, that the mortal shell he had created possessed the form and memories of a young medical student whom Odin had selected to be Thor's mortal template.
    • In Thor #415, Eric Masterson accessed the memories that he now shared with Thor and recalled that Odin had used Keith Kincaid, then a young medical student, as a template for a physical, mental and emotional duplicate who became Donald Blake.
    • Many years later, this was called into question when Thor discovered Don Blake in stasis, a being separate from him and preserved at the exact moment he first struck his magical cane to unleash Thor. Blake awoke from stasis with no memory of any events after that fateful trip to Norway. Over time, Thor learned that Odin indeed used a REAL man named Don Blake as his human host. When Blake discovered Mjolnir, he was placed in suspended animation while Thor retained an aspect of Blake within himself that he could transform into. Odin then admitted that he had lied about using Keith Kincaid as a template because he wished for Thor to believe that Blake had not been a real mortal. However, a further and complicated series of events revealed that the Blake found by Thor was not the original, but a magical construct left in place of the original by Sigyn after she accidentally killed the real Blake while in stasis.[17]
    • In recent years, the magical construct or aspect of Don Blake resurfaced after Ragnarok. It was this incarnation of Blake that reconnected with Mjolnir and resurrected Thor, becoming a part of him once more.[5][6]
  • He usually vacationed in Florida.[18]
