8 Intriguing Theories About The Man In The Iron Mask’s Identity In The Flash

6) Eddie Thawne

When we last saw Eddie Thawne, he shot himself through the heart in order to wipe his descendent Eobard (a.k.a. Reverse-Flash) from history. His body was then sucked into the Singularity, and who knows what sort of changes it could have gone while passing through that doorway.

In fact, there’s a chance that Earth-2 technology could have been used to save his life, and if that’s the case, it means that the Reverse-Flash could make a return somewhere down the line, too.

However, with Iris and Barry seemingly about to finally embark on a romantic relationship, Eddie’s return would throw a real spanner into the works for them, and if he has been given powers of some sort, his presence in season three of The Flash could shake things up in a very big way.
