Around the internet there is a theory that Damian Wayne, (Bruce Wayne AKA Batman's son) is set to play a major character on CW's [Arrow](series:720988). TVLine.com posted a Q&A between a fan and Michael Aussiello, who is a TV Guide senior writer. It was a short Q&A, only one question but here it is.
Q: "Anything cool coming up on Arrow?
A: "The show’s Season 3 finale will introduce a major, formidable, fierce new foe for Oliver, and his reign of terror will continue well into Season 4. The mysterious character is being referred to internally as “Damian Dark,” which got Matt Mitovich and I (but mostly MM) pulling up and skimming the Wiki page of one Damian Wayne. Get it? Damian Wayne. Son of the Dark Knight. They’d probably have to tweak the Bruce Wayne connection, but it’s a plausible theory, no?"
Now introducing Damian Wayne without Bruce or Talia, and making him an adult able to face Oliver, makes him almost nothing like Damian Wayne. Which got me thinking maybe Damian Dark is Damien Queen. No, I am not talking about Connor Hawke who we know is an eight year old living in Central City.
To explain this, you need to know Damian Wayne's backstory. Damian Wayne was created from the DNA of Bruce Wayne and was genetically modified to be perfect as he was growing in an artificial womb. Now they could have changed it a little bit and made it so he was grown from the DNA of Oliver Queen and artificially aged him to around Oliver's age.
Now another, more likely theory is that it is actually Damian Darhk, a H.I.V.E. operative from DC Comics, which would make more sense, as they've been leading up to H.I.V.E. being the big bad for season 4 and it wouldn't make much sense to have the attention taken away from that.
P.S. This is my first post thank you for reading and sorry it's not that great, it's 3:27 a.m. and i'm tired.
