Thor was asked by Col. Nick Fury to investigate Beta Ray Bill's starship when it was detected by a S.H.I.E.L.D. hyper-spatial probe. Entering the ship, the central computer alerted its protector and in the ensuing battle, Thor was separated from his hammer Mjolnir and reverted to Dr. Donald Blake, as well his hammer reverted to it guise as a walking stick. Seizing the walking stick and striking it against the wall, Beta Ray Bill was transformed into a variation of Thor.
Requiring Thor, Odin cast a spell to return him to Asgard, but the newly transformed Beta Ray Bill arrived instead. Odin transported Dr. Blake to Asgard as well - restoring his form as Thor. Beta Ray Bill initially though the Asgardians were in league with Surtur's demons, but when convinced otherwise refused to return Mjolnir, insisting he has won the weapon fairly in combat and needed it to battle Surtur's demons. Odin decreed the matter be settled by a combat to the death, without the advantage of the war hammer. Beta Ray Bill proved victorious but refused to kill Thor. Satisfied that the alien was noble, Odin had another war hammer forged and enchanted it with the ability to transform the alien with the powers similar to Thor's - christening the weapon Strom Breaker.
Odin also transferred the spell that allowed Thor to transform into Dr. Donald Blake to allow Beta Ray Bill to transform himself, as well as transforming Storm Bringer into a walking cane when not in the form of Beta Ray Thor.
