Behind the scenes

  • This Earth's designation is likely a reference to the number of the beast out of the sea in Revelation 13.
    • Although 666 is generally believed to have been the original Number of the Beast in the Book of Revelation in the Christian Bible.In 2005, however, a fragment of papyrus 115 was revealed, containing the earliest known version of that part of the Book of Revelation discussing the Number of the Beast. It gave the number as 616, suggesting that this may have been the original.
  • Supergirl is an in-universe television series that exists in the Lucifer universe.
