20 Unanswered Questions From 2017's Comic Book Movies
5. Who Won The Race Between Superman & The Flash? - Justice League
The Question: Justice League's mid-credits scene features Superman and The Flash (Ezra Miller) preparing to race one another, but before the race begins, the scene cuts away, leaving viewers to debate the result. So, who actually won?
The Likely Answer: This will almost certainly never be answered officially because the mystery is just way more fun, but the history of DC Comics would generally side with The Flash.
Given that the main facet of his superpowers revolves around speed, it would make sense that he'd be faster - even if marginally so - than Supes, while the Man of Steel has plenty of other bells and whistles to ensure he's still a ludicrously powerful member of the Justice League.
If Superman wins, it's just another reason for his detractors to call him "over-powered", but The Flash potentially getting one over on Supes is way more interesting and satisfying, especially as the character was the best thing about Justice League.
