When Zoom was "killed" at the end of The Flash season 2, observant fans noticed how the character's grotesque transformation made him resemble a certain other iconic speedster from DC Comics -- namely the Black Flash. A grim reaper who punishes speedsters for creating time aberrations, the visual similarities between Zoom's final form and the Black Flash were simply too blatant to be shrugged off. Instead, many fans began to wonder if Black Flash would be returning to The Flash at some point down the line, in case Barry or any of his fellow Speedsters made more mistakes in the timeline that they (once again) tried to run away from.

However, it was recently revealed that Black Flash would not be returning to The Flash, but actually Legends of Tomorrow. The reason for the character's crossover was left mysterious at the time, but thanks to tonight's episode of Legends, that mystery has been solved.

As it turns out, Black Flash is after Eobard Thawne, who is busy trying to get the grim reaper off his path -- through any means necessary. A new gif from the show's official Twitter account has revealed the first look at the Black Flash's return in the series, which you can check out for yourself below:

Revealed tonight, Legends of Tomorrow finally explained why Eobard had been mostly absent from a majority of its season so far, and it all has to do with Black Flash it seems. Originally erased from existence at the end of The Flash season 1, Eobard himself is basically an aberration for merely still being around, which has made him a prime target for the Black Flash to try and hunt down. As with most of the prominent speedsters that have been introduced thus far, Eobard is busy trying to rewrite history so that he will no longer be said target.

Now, considering just how heavily Legends has focused on time travel and the ramifications of altering with the timeline previously, Black Flash seems like the perfect antagonist to be introduced into it. But with that being said, there's no telling what exactly the character's existence has turned into since Zoom was first torn apart by the time wraiths, and it'll be interesting to see if the Black Flash is ever fleshed out as a full character, or is merely just a force meant to punish Eobard for his past sins. Either outcome could make him a formidable villain to be reckoned with on the series -- who just adds yet another exciting new layer to the show's ever-evolving second season.

Legends of Tomorrow continues Tuesday, February 7 with ‘Turncoat’ at 9pm on The CW.
