It was recently announced that Matt Ryan would be reprising his role as John Constantine in The CW's Arrow Season 4, following the cancellation of NBC's Constantine. A statement released by Arrow Executive Producer Marc Guggenheim stated that "the introduction of magic and mysticism on the show [Arrow] this season has provided a truly organic opportunity for us to bring John Constantine to Arrow and The CW's DC Universe". One piece of magic which we have already seen in the show, and which will play a huge role in the whole Arrowverse this coming year, is the Lazarus Pit. It will be through use of the Lazarus Pit to bring back Sara Lance that will see Constantine introduced into the show.
While Guggenheim went on to say that this was a "one time only deal", it is possible that if the episode garners success then it will become a two time deal, then a three time, and so on. Constantine's role in Arrow could provide the character with enough exposure to resurrect the Constantine solo series, but this time within the Arrow Universe itself.
One thing that the introduction of Constantine allows The CW to do is bring other characters into their universe. Constantine will be the first real sorcerer we have been subjected to, and he could open a gateway to similar characters or other characters from the Hellblazer stories.
One important magician in the DC Universe is Zatanna. She is immensely powerful, even more so than Constantine, and is an integral character in many DC Comics storylines. Moreover, she has the ability to show a fun side but is committed to a fight for justice. Zatanna and John Constantine have actually been shown have a relationship together on multiple occasions.
Another character who is truly vital to Constantine, because it was on his DC Comic series that Constantine was introduced, is Swamp Thing. Swamp Thing is literally what he sounds like...a swamp...thing. He is a mass of mutated swamp with the memories of human scientist Alex Holland, taking the form of an enormous, horrific-looking creature. Swamp Thing, among many of his powers, can control vegetation and use this to transform his own body. Using these, and other powers, he acts as a hero with the appearance of a monster.
Doctor Fate, another being able to control and use magic in the DC Universe, could be introduced through John Constantine. Doctor Fate's helmet grants him an almost completely mastery over magic, although unable to counteract spells which have already been cast. He plays a big role in the Justice Society of America and in the greater DC Universe.
Other characters include Deadman, Shade, Doctor Mist and Animal Man, among many others.
If The CW were to introduce all of these new people (some of them aren't people) could we be seeing a Justice League Dark Spin-Off somewhere down the line? For those who aren't aware, The Justice League Dark is a superhero team up of characters who are able to use magic, created under the realisation that the traditional Justice League were poorly equipped to handle supernatural foes. Currently, Doctor Fate is not a member of the JLD, nor is Animal Man, but were they all to be introduced into the Arrowverse then they could become members. This could be another way for The CW to successfully expand their roster of DC TV shows.
It would not be difficult for The CW to gain the rights to these characters. While there is a Justice League Dark film in the early stages of development, written by Guillermo del Toro, it is not in the DC Cinematic Universe's current slate of planned releases. This means that DC will be less protective over these heroes. Furthermore, as many are not familiar with these characters it would make sense for DC to want to let them gain traction with an audience and popularise them before a cinematic release.
The CW have a good track record for making successes out of little known DC characters, such as The Atom and many villains including Rainbow Raider and The Pied Piper. I am sure that they could be able to write these characters well and integrate them fully into the universe they have already built.
So what do you guys think? Which characters would you like to see introduced into the Arrowverse? Do you think Constantine will be a success on Arrow and, if so, do you think success could mean a potential reinstatement of a solo series? Let me know what you think down below.
