Barry Allen, The Future Flash
The DC Comics Universe has already dealt with a "Future Flash" in its New 52 era, with an older Barry Allen coming to realize that his jaunts back and forth through time (dozens more than even the show has featured thus far) haven't been as harmless as it appeared. Twenty years into the future, Barry begins to sense that time is disappearing. When he runs at full speed, minutes evaporate without a trace - resulting in his inability to save Wally West from a fatal car accident. Realizing that he has caused the Speed Force to be torn apart this far into the future, he accepts that his only course of action is to travel back in time and seal the rift when it began... and to do it, he's willing to gain the necessary power by whatever means necessary. Generally, that means killing his enemies.
He leaps backward years at a time, preventing his enemies from their most terrible, unintentional acts. He still leaves them to be killed, justifying it to himself by saying that none of these murders will matter if he can undo the entire timeline from taking place. Finally arriving from the future, this murderous version of Barry confronts his younger self - noting that his costume is far less advanced than his own metallic, blue, glowing armor - and revealing that only the young Barry possesses enough energy to seal the Speed Force rift completely. Killing his younger self will release that energy and prevent all the damage he caused in his future, even if he appears to all as a murderous, crazed, desperate monster.
For the modern Barry, it's a nightmare come true: he sees himself, older, armored, and hellbent on killing anyone with the Speed Force connection needed to undo his mistakes - mistakes caused by altering the timeline, leading to a future far worse than the one that could have formed naturally. Do we need to spell it out any clearer?
Barry May Have Warned Us Already
The show clearly isn't adapting that story ("Out of Time") beat for beat, but with a few tweaks, it does seem like a possible basis for the season's threat. It's not hard to imagine that decades into the future Barry realizes just how horribly he impacted the future by traveling back in time and creating Flashpoint - or who knows, maybe it's another upcoming change to the timeline that causes it (the cost of saving Iris, even). Knowing the only way to fix the future is to travel back to the past, but lacking the speed to do so due to his fracturing the Speed Force beyond repair, Barry has only one option. Track down speedsters, capture their Speed Force energy as Zoom once did, and begin his long trek back in time.
It's not the heroic future fans would hope for, even if that sacrifice and commitment to do unspeakable acts could be viewed as noble, in some sense. But Barry Allen may have already offered a warning stating that is exactly what winds up happening. And he delivered it all the way from the year 2056, directed to Rip Hunter, the last remaining Time Master, as seen in the "Invasion" crossover of 2016:
"A war is coming, Captain Hunter, and at some point you’re going to be called back to Central City to fight it, so you need to know that — while you and your team have been in the temporal zone — I made a choice that affected the timeline. As you know, whenever you alter the past, those changes affect the present and get compounded in the future. When you return, you will be in a new timeline I created, where everyone’s past and everyone’s future has been affected, including yours. When you come back, don’t trust anything or anyone, not even me.”
The message was delivered in the midst of the Dominator invasion, and was therefore taken as relating directly to it. Barry changed the timeline, and maybe that's why the Dominators arrived. But pull out the facts: Barry altered the past, saw how the effects "compounded" four decades into the future, and warns that in the new timeline being formed nobody is to be trusted... not even himself.
If you ask us, that sounds an awful lot like the kind of message Barry might send before beginning his mission to make a more terrible present throughout the timeline in hopes of changing the past to save the future. And THAT would be a brand new way to say that Barry Allen created his greatest enemy - himself.
Savitar Reveals Himself
The latest twist may reveal the truth behind Savitar's identity... or keep things exactly as they were. We speak, of course, of Savitar revealing himself to Killer Frost. Meeting Caitlin Snow finally in the form of her alter-ego, Killer Frost, Savitar lays on the same kind of language all over again. He has been "waiting" for her to arrive, and seems to possess so much knowledge of the future, that these people locked into making it a reality as almost his "children." Needless to say, Killer Frost is in need of some convincing before she will trust this hulking, glowing villain at all.
Instead of relying on words, Savitar gets down on all fours, and opens his armor... revealing a living, breathing (seemingly fleece-clad) man. And while the audience may only see his boot and leg, Killer Frost needs no more convincing. She knows the man well enough to know that her best bet is to do as he says. Some have taken this as a sign that the figure is her presumed dead husband, Ronnie Raymond (Robbie Amell). That seems like a bit of a stretch, since it's based on little actual evidence - sure, Ronnie may have been sucked into the Speed Force and thrown backwards in time to become the first speedster... but we just made that up whole cloth.
It seems just as likely for fans to see this scene as further evidence that it's an older Barry Allen - since that reveal would convince Killer Frost she was out of her element, or clearly a pawn in a far more dangerous game. We won't know for sure, but we would advise fans to not waste too much time analyzing the physical person in the suit. Earlier reports claimed that actor Daniel Cudmore (the X-Men movies' first Colossus) would be performing the part of the massive Savitar, which makes him the obvious answer. We don't expect him to be the "revealed" Savitar Barry Allen will apparently also recognize.
Let us know what you think of our theory, and share your own prediction for Savitar's identity in the comments.
The Flash airs Tuesdays @8pm on The CW.
