10 DC Universe Canon Questions The Flash Movie Can Answer

The Flash (2023) can settle multiple DC Universe canon debates. While the multiverse has been part of DC Comics for decades, The Flash movie will bring it to the silver screen for the first time. The Flash is expected to be one of DC’s biggest releases in years and will feature multiple characters.
Despite being the first theatrical Flash movie, The Flash will not be a small-scale superhero adventure. The Flash will dive intothe DC multiverse, loosely adapting elements from DC Comics’ Flashpoint arc. In addition to all the questions about the multiverse, The Flash can also solve a few mysteries regarding Barry Allen’s origin story and the Justice League in the DCEU. Here are 10 DC Universe canon questions The Flash can answer.
10 How & When Did Barry Allen Become The Flash In The DCEU? The DCEU skipped the Flash’s origin story. The DCEU's Barry Allen first appeared in Batman v Superman: Dawn of Justice, when a future version of the Flash showed up at the Bat-cave to warn Bruce about Superman. Batman would later find security footage from a meta-human from Central City in Lex Luthor’s files. Therefore, Barry Allen already had his powers during the events of Batman v Superman. However, it was not clear whether the Flash as a superhero already existed at that point. Present-day Barry Allen appeared as the Flash for the first time in Suicide Squad (2016).
Considering that Superman was the first known superhero in the original DCEU, Barry Allen became the Flash somewhere between 2013 and 2016. The Flash’s origin story usually involves Barry being struck by lightning at a lab, which is what probably happened to the DCEU’s Barry. That said, the DCEU’s Barry Allen only got a job at a forensic lab during Justice League. Therefore, how the Flash gained his powers in the DCEU may be slightly different from the usual DC canon. Regardless, The Flash will probably revisit Barry’s origins, as suggested by the trailer.
9 How Did Nora Allen Die In The DCEU? Nora Allen’s death is a major event in Barry Allen’s life. In the modern DC lore, Nora’s mysterious death, which happens when Barry is still a kid, is what inspires Barry to use his powers to become a superhero. The death of Barry’s mom was the foundation for the Flashpoint storyline and has been revisited in adaptations like The Flashpoint Paradox and CW’s The Flash. Now, the DCEU will get to add its own spin on it. Barry going back in time to save his mother is what will break the universe in The Flash.
However, how the Flash's mother died in the DCEU remains unknown. In DC Comics lore, the Reverse Flash killed Nora Allen. However, there has been no indication from trailers or spots that the Reverse Flash will appear in The Flash movie. So far, General Zod and the Kryptonians from Man of Steel are the only officially announced The Flash villains. It will be interesting to see how the events of Nora Allen’s death played out in the DCEU, and who was responsible for it.
8 Which Justice League Version Is Canon To The DCEU? There are two versions of the Justice League movie. The theatrical Justice League cut was released in 2017, while Zack Snyder’s Justice League, the Snyder Cut, was released in 2021. The Snyder Cut, which was more than two hours longer than the theatrical cut, was vastly different from 2017’s Justice League. The Snyder Cut and the theatrical Justice League cut differ not just in terms of tone and runtime but also in terms of lore. For example, Silas Stone dies in Zack Snyder’s Justice League but survives in the theatrical cut. Likewise, Barry Allen mentions and uses time travel in the Snyder Cut but not in the theatrical cut.
