When it comes to Wally West, it’s worth pointing out that there are entire runs of The Flash where he is the hero who is known as the main Scarlet Speedster. He is technically the third person who has taken on the mantle of The Flash and he could one day take on that mantle in the DCEU. However, at the moment, both the television shows and the movies are focusing on Barry Allen being the speedy hero. In fact, Barry Allen is getting his own movie in the near future and Ezra Miller (at least for the moment) is still the one who is taking on the character.
