I, like many others, am really excited for Arkham Knight, even though if I do get it I would technically be breaking the law because I'm not quite 18 yet and my biggest problem is I don't have a PS4 but I will get This!
Anyway, here lies a list of who I think could potentially be yours truly, the arkham knight. (This not listed by the most likely just who it could be).
1. Damian Wayne:
He would have had the training with the league of Assassins, We know that Talia and Bruce had a wild night in Metropolis because Talia says so in Arkham City. He would have been brought up to hate his father but he wouldn't be very old and when we hear AK (Arkham Knight) speak he sounds like an Adult. Likeliness 6/10.
2. Jean Paul Valley:
We've all heard the prophecy that he says in Arkham City so I won't put it in here but anyway he has the training and that's about it. He doesn't really have a hatred towards Batman and all he would get of it is making the prophecy come true. I think that he will be the one to defeat the Arkham Knight once Batman becomes critically injured. Likeliness 2/10.
3. Lincoln March
He has the training, he tries to kill batman and he thinks he's Bruce Wayne's brother. I personally think that it is him because he makes the most sense to me. Likeliness 8/10.
4. Tommy Elliot / Bruce Wayne:
He hates Batman, He has the resources and also we left him Arkham City wondering, I bet in 2 games time he will come back as an awesome looking guy trying to kill Batman. I don't think it is because of my Owlman theory. Likeliness 7/10.
5. Ra's Al Ghul:
He has the training, a hatred against Batman/Bruce, the resources and the lazarus pit to heal himself after the events of Arkham City. There is a really high chance that it will be him. Likeliness 9/10.
We might not even get to find out.
