After Constantine, Five DC Comics Characters Who Should Appear on Arrow

GANGBUSTER

This one's kind of a cheat, since we thought at one point that it might be an identity Diggle might take on.

Still, the character of Jose Delgado -- an advocate for troubled youth who eventually lost his patience with the system and decided to battle gang violence and the occasional supervillain in an armored suit -- would fit right in with Arrow, where a mayoral candidate, his campaign staff and the distict attorney are working outside the law to protect the city.

And, in spite of an increased representation in the pages of the comics, hispanic superheroes haven't really broken through to the screen yet. It seems like introducing a character who represents diversity without having to swap out the race of the character with that of a new actor, would be a win.

If there's a big downside, it's that Delgado and the Gangbuster persona are associated not only with Superman -- but specifically with Cat Grant, whom he dated for a long while in the comics. It might, therefore, be hard to wrest him away from Supergirl, unless executive producer Greg Berlanti (who works on both shows) sees more potential for Delgado in Starling.

JIM CORRIGAN/THE SPECTRE

One character introduced in Constantine and begging to be explored a bit more is Emmet Scanlan's Jim Corrigan.

Scanlan, recognizable to comics fans as one of the Kyln guards from Guardians of the Galaxy, appeared in a few episodes of Constantine during its 13-episode run...and his comic book destiny as an agent of God's wrath was certainly hinted at pretty strongly (see above).

Scanlan did a great job embodying the show's vision of Corrigan, and while the sheer level of power wielded by The Spectre might be a difficult sell for a show as grounded as Arrow...but in a season dominated by magic, having a powerful spirit come in for the wrap-up could be cool.

And, hell, I just want to see how Scanlan's no-nonsense version of Corrigan bounces off Lance.

DOCTOR THIRTEEN

Dr. Terry Thirteen never quite made it onto Constantine, although he would have if the show had lasted just a little bit longer.

But in a season dominated by so much magic and mysticism, you know what would be great? If we had a skeptic. So far, Oliver tells people stuff and they just believe it. Terry Thirteen would add something dimensional to the existence of magic in this world.

Also, Traci 13. 'Nuff said.

DAVID CAIN

A meticulous hitman with ties to both Deadshot and the League of Assassins, David Cain seems like an obvious choice for Arrow.

One has to assume that not everyone in the League of Assassins is happy with Merlyn's leadership -- both because he was an enemy to the League for so long and because he didn't come by Ra's al Ghul's ring honestly.

He could be a return to form for Arrow, whose first two seasons featured control-freak League of Assassins-trained loners but whose third and fourth seasons have been Team Arrow versus a giant mob of largely nameless villains (yes, there were elements of that in Season Two as well, but it was very much Arrow v Deathstroke). It could also challenge and inform Oliver's moral code, allowing him to come to the same conclusion Batman did after training with Cain: that just because one knows how to kill, doesn't mean they must or should use that knowledge.

And, most important of all, using Cain would give Arrow the chance to title the second-to-last episode of one of the seasons "Adam Raised a Cain," which is a Bruce Springsteen song (they name the second-to-last episode of each season after one of his tunes).

Slide 5

This is one that comes up every year, but there's a good reason for it: he would be a great fit.

As written in the comics, The Question is often depicted as Randian in his philosophies politically, a counterpoint to Oliver Queen's outspoken liberalism. While showrunners have expressed that it's nearly impossible to make a character too political on TV given how divided the country is, carrying that over and making The Question an invaluable ally on the battlefield but one Oliver can't stand personally -- maybe even going the Watchmen route, there -- could be an interesting dynamic.

They flirted with that a little bit with Merlyn last season, but Merlyn is a special case. His status as Oliver's arch-nemesis tends to supercede any one storyline they try to put him in, and so they can't play a "wow, I hate that guy" subplot too straight lest the audience basically collectively say, "Well, OF COURSE."

And, hell: The Question has already kinda/sorta been hinted at; two episodes ago, Merlyn talked about a "sage" in Nanda Parbat who could help Thea. He later said that person didn't really exist, but it hasn't stopped readers, tweeters and even comics writer Adam P. Knave from suggesting he could have been talking about VIC Sage, who has a connection to Nanda Parbat.
