The Flash: Who Is Savitar?

Since Savitar has begun wreaking havoc on Central City, Barry has been tormented by this seemingly unbeatable foe.

[...] if you switch up the punctuation a bit, you could also read his answers as "I'm the Future Flash," thus revealing he is either someone who took up the Flash mantle in the future or is literally a future version of Barry Allen.

During the Legends of Tomorrow portion of the massive four-way crossover last fall, Barry sent Rip Hunter a message from the year 2056.

In it, Future Barry revealed he made a choice that drastically affected the timeline and that when Rip and his crew returned to the new timeline they shouldn't "trust anything or anyone, not even me."

Wally (Keiynan Lonsdale) discovering he was a speedster in Flashpoint and chasing that identity, Caitlin (Danielle Panabaker) doing everything she can to repress her evil alter ego Killer Frost, Julian learning that he was unwittingly the villain Alchemy, etc.

[...] while there's always a chance Savitar's identity will follow that storyline and he'll be revealed as someone we've never met before, that's highly unlikely (and would be a major disappointment, tbh).

[...] The Flash does love to draw inspiration from the DC comics and put its own spin on it -- something they might be doing by combining the Savitar storyline with a complicated Barry vs.

[...] of this, Barry was unable to prevent the death of Wally West.

What Young Barry doesn't know is that Murderer Barry is killing all these people -- and plans on killing his younger self -- to prevent all the future horror he caused by messing with the timeline (which is, conveniently, already an issue our Barry has been dealing with all season).

[...] although the storyline doesn't match up completely, we think there are more than enough similarities between the two to securely position Barry as the most likely suspect in the "Who is Savitar?" debate.
