'Arrow' latest news: 'John Diggle' puts up crazy Instagram shot with 'Iron Fist' star Finn Jones

David Ramsey and Finn Jones are from two separate comic book worlds, but that doesn't mean they cannot fool around. The actors who play John Diggle/Spartan and Danny Rand/ Iron Fist, respectively, shared a rare moment at the Puerto Rico Comic Con by posing side-by-side.

Seeing the two together is rare, mainly because both are from rival comic book companies. This means any hope of a crossover project between the two is improbable – at least for now. The Instagram post of Ramsey can be found here, complete with a caption that reads "John Diggle vs. Daniel Rand Spartan vs. Iron Fist DC vs. Marvel."

Other than that, comic book fans hoping for a potential crossover involving DC and Marvel should keep dreaming. Both companies are busy building their own base of TV shows, meaning DC and Marvel would prefer to hype their own superhero lineup than open doors to an uncanny alliance.

David Ramsey recently wrapped up season 5 of "Arrow," and most are eager to see what the sixth season will bring. For those who missed the finale, Diggle/Spartan was among Oliver Queen's (Stephen Amell) friends trapped on Lian Yu, which got blown up as planned by Prometheus/Adrian Chase (Josh Segara). Team Arrow is expected to survive the mishap, with season 6 picking up from there.

On the Marvel side of things, Jones finished his first season reprising the role of Dan Rand/Iron Fist. He is scheduled to join forces with other New York-based superheroes on "The Defenders" on Netflix this August. He joins the likes of Matt Murdock/Daredevil (Charlie Cox), Jessica Jones (Krysten Ritter) and Luke Cage (Mike Colter).

Aside from "The Defenders," Jones may end up working on a potential second season of "Iron Fist." Another possibility is seeing Danny Rand team up with Luke Cage, which would be based on the comic books series titled "Heroes for Hire."

With countless possibilities for either side, it would be interesting to see a rare DC-Marvel crossover coming to fruition. Anything is possible moving forward, though it would require heavy discussions and proper pencil-pushing. Seeing how the companies have invested pushing the stars of their respective series, a big obstacle would be the budget side of producing something that fans will certainly find interesting.
