The Flash Season 2: 7 Theories On The Man In The Iron Mask's Identity

7. A Character We Don't Know

This is the one that would, to an extent, require the least explaining, and yet also be the most disappointing.

I don't envisage that it'll just be any random character under that mask, but it could be someone of importance that we haven't met yet. There are still plenty of comic book characters that haven't turned up on the show, and it could be a stealthy way of introducing them here, someone like Bart Allen, for example.

To people aware of the character it would certainly be a big twist, but not necessarily a good one, and a bit of a waste. Would it be beautiful and blow our minds? Probably not. Unless it's the Green Lantern under there (we can keep hoping the character will make his way to The CW, right?), this seems the least likely scenario, but still one that can't be fully ruled out just yet.
