Marvel Comics has permanently altered Thor's history in the pages of The Immortal Thor #25, in which Loki uses the mystical Arrow of Eternity to erase Thor and Asgard from Earth's past and present. The retcon reshapes decades of Marvel continuity, replacing Thor with Beta Ray Bill as a founding member of the Avengers, while Thor himself is reborn as a powerless mortal, stripped of his godly status.

The new series Queen in Black #1 shows the fallout of this altered reality for the first time, though its main plot centres on Hela's invasion of Earth. A key moment in the issue instead focuses on Beta Ray Bill, revealing how isolating it has been for him to occupy Thor's former role as an Avenger following the timeline change. The development comes as Marvel signals a broader shake-up to Thor's story ahead of his anticipated return to the MCU.
