Tom Ellis’ Lucifer Morningstar is officially part of the Arrowverse canon - but the move comes with several intriguing questions. Ellis made his debut as the infamous fallen angel on Fox’s Lucifer back in 2016. Based on a version of the character created by Neil Gaiman - and then spun-off into the solo series by Mike Carey - Lucifer offered a fresh take on the well-known character. After countless millennia ruling over Hell, Lucifer and his trusted lieutenant Mazikeen abandoned their duties. Heading to Earth, Lucifer opened a piano bar called Lux and dedicated his life to indulging the desires of himself and select humans. After a chance meeting with a detective named Chloe Decker, however, the carefree lives of Lucifer and Maze were forever changed and made altogether more complicated.
After three seasons, Lucifer was canceled by Fox and then resurrected by Netflix. Lucifer season 4 debuted on the streaming service in mid-2019, garnering even more popularity. Shortly after the shortened, 10-episode run, Netflix renewed Lucifer for a fifth and final season. So the conclusion of Lucifer’s story is wrapped up successfully, it was also confirmed that Lucifer season 5 will be comprised of 16 episodes. Fans didn’t have to wait for those new episodes to see Ellis return to the besuited role, however. Despite numerous denials, Ellis popped up for a brief appearance in the Crisis on Infinite Earths crossover event. The cameo immediately provoked a desire to see a show centered on Lucifer and John Constantine developed as the next Arrowverse spin-off.
So as not to mess with the established continuity, it was revealed that his Crisis on Infinite Earths appearance takes place before the events of Lucifer’s pilot. With Oliver Queen having sacrificed his life, Constantine, Mia Smoak, and John Diggle set out to restore him. With magic weakening due to the actions of the Anti-Monitor, the trio sought out Lucifer to gain access to Purgatory and thus retrieve Oliver’s soul. Established as owing Constantine a mysterious debt, Lucifer honored his end of the deal. After the excitement of Lucifer’s appearance died down, many fans found themselves with questions for what it meant for the Arrowverse.
Primarily, many wondered whether this meant that there were potentially infinite versions of Lucifer lurking out in the multiverse. After all, doppelgängers for many characters - both heroic and villainous - have emerged across the wider Arrowverse. As such, it’s reasonable to think that the same could go for the King of Hell. Unfortunately for those who looked forward to different iterations of Lucifer potentially showing up in the future, there’s a vital clue that implies there is only one version of him - even throughout infinite universes. That clue is the fact that Constantine, Mia, and Diggle had to venture to the aptly named Earth-666 to encounter Lucifer. Given how much easier it would have been to call upon the Earth-1 version instead, the only explanation is that there simply isn’t one.
That would also no doubt go for Hell, Purgatory, and, presumably given the established lore of Lucifer, even Heaven. Similar to The Vanishing Point that Pariah ultimately sent the seven prophesized paragons, Hell and the rest are most likely extradimensional. Existing outside of space and time, the biblical destinations are probably infinite in their own right and no doubt connected to each and every possible universe. As such, though each Earth was decimated as part of the huge Crisis on Infinite Earths Part 3 cliffhanger, there’s every chance Lucifer was able to survive by simply going home. Whether or not that means Ellis will make another appearance in the final two Crisis on Infinite Earths installments - or ever again within the Arrowverse - is unknown. One thing is for sure, though. The fact that he has no doppelgängers is actually kind of fitting, given Lucifer’s evidently one of a kind nature.
