With just a few weeks left untilThe Flash Season 3premiere, The CW has unveiled a new extended trailer, which shows more of the alternate universe Barry Allen created. In the Season 2 finale, Barry Allen (Grant Gustin) used the speed force to go back in time and save his dying mother. In the comics, when Barry did this, it resulted in the Flashpoint Paradox, a new alternate universe which is starkly different from his own world. If that wasn’t enough, we also have a new poster with Barry Allen.
Grant Gustinfirst revealed that this season will center on theFlashpointcomics two months ago, where he teased on Twitter thatThe FlashSeason 3 premiere will be calledFlashpoint. The Flashpoint Paradox comics debuted in 2011, written byGeoff Johns. It is set in a world that has been drastically altered, where Barry Allen wakes up one day and realizes he has no powers, and he is also the only one that realizes how other DC Comics characters have been altered. For instance, Captain Cold has become Central City’s hero, the Justice League no longer exists and it was actually Bruce Wayne who was killed when he was just a boy, instead of his parents. These comics lead into DC’s New 52 reboot of their comic book lineup.

In the Season 2 finale, when Barry saved his mom, it resulted in the Flashpoint Paradox, and we learned in the sizzle reel shown at Comic-Con that the show is following the comic books in this respect. This new trailer also gives us another look atDoctor Alchemy, who will be voiced byTobin Bell. In the DC Comics, the villain has the ability to turn elements into anything he pleases, even turningThe Flashhimself into water vapor at one point.
It has also been confirmed thatThe Flashwill team up withSupergirlfor amusical crossoverat some point this season. Last season,Grant Gustinguest-starred in a crossover episode ofSupergirl, when the show was airing on CBS. Executive producerGreg Berlantihas said that the crossover will largely feature cover songs, but there may be a few original songs thrown in the mix as well. There have been rumors thatJoss Whedonwill direct this episode, but that has not yet been confirmed.
