The Flash Season 2: 7 Theories On The Man In The Iron Mask's Identity
1. Future Barry Allen
Although a couple of the theories on this list already could be considered a bit 'out-there' (and indeed I've tried to simply go with the more sensible/doable ones, rather than throwing just any character in), this would be the whackiest.
The one thing we know about Barry's future is that, in 2024, he goes missing (oh, and he marries Iris, but that's rather less important to the identity of the man in the iron mask). So, what if it was Zoom who stole him from the future, brought him back to the past, and locked him up? For what reason, I'm not sure - maybe future Flash travelled to Earth-2, or Zoom realised he needed him in order to steal present Flash's speed.
The tapping of JAY could be explained as trying to inform the others of Zoom's identity, if that's the name he goes by (that could go for the other theories too, I suppose), and, well, it'd certainly be a big, mind-blowing twist on things.
Who do you think is the man in the iron mask? Is it one of these, another character, or just Leonardo DiCaprio? Share your own theories down in the comments?
