In any case, the potential for a very different Barry has been foreshadowed by the CW series all season.

It would also make sense for Earth 2 Barry to have some beef with Earth 2 Dr. Perhaps Zoom is a peek into what the world would look like if the Flash did not have that kind of support system. Could Barry's Earth 2 self be an evil villain determined to be the only speedster? Barry started this season attempting to push away those who were close to him out of fear of putting them in danger. Maybe the only speedster in the universe faster than Barry is, well, Barry! Harrison Wells (Tom Cavanagh) has already proven that characters' Earth 2 versions can have drastically different personalities. Here are four possibilities about Zoom's true secret identity: Zoom (Tony Todd, left) pins Barry Allen (Grant Gustin) in episode 6 of Season 2 of 'The Flash.' The CW The photos of the masked foe raise one very important question: Who is Zoom? Tony Todd has been the man behind the digitally altered voice of the bad guy, but who is hiding beneath the mask? Earth 2 and the multiverse allow for a crazy number of wacky possibilities, so the Internet has been getting crowded with theories - Reddit users even began spreading a theory that Zoom is Patty Spivot (Shantel VanSanten) as a sarcastic response to all the speculation. Now, thanks to promotional photographs (shown above and below) of episode 6, 'Enter Zoom,' viewers can actually see what all the fuss is about - to be fair, the character has made a few cameo appearances this season already, but now fans can really size up the usually-supersonically vibrating speedster before he and Barry get down to business. The villain has left a pretty big impression on Barry's (Grant Gustin) new Earth 2 friends, and every metahuman the Flash has faced this year has been sent by Zoom to kill him. Throughout five episodes of 'The Flash' Season 2, all fans have been hearing about is Zoom (Tony Todd). Zoom (Tony Todd) makes his debut in episode 6 of 'The Flash' Season 2.
