As Arrow careens towards its upcoming finale, one of the biggest Season 3 surprises is that Ra's al Ghul hasn't quite turned out to be the villain every one expected. It sounds like someone bigger, and badder is coming in the Arrow Season 3 finale, though. And it might just turn out to be Ra's al Ghul's grandson.

TVLine reports that the Arrow Season 3 finale is set to introduce a major villain that will recur in Arrow Season 4. This will be a fierce, formidable new foe for Oliver Queen (Stephen Amell), and this villain is set to unleash an unstoppable 'reign of terror'. At The CW, those working on the series have referred to the character as 'Damian Dark'. This has led to some strong speculation that Damian Dark is actually Bruce Wayne's son Damian Wayne.

TVLine thinks that the Bruce Wayne connection will have to be tweaked, but that this is a very plausible scenario. Damian Wayne is the son of Bruce and Ra's al Ghul's daughter Talia. It is unclear how Damian's backstory will be changed, but the DC Comics character fits the new show's villain description quite well. What do you think?
