While the first post-credit scene teased an iconic race around the country between The Flash (Ezra Miller) and Superman (Henry Cavill), the second hinted that the Legion of Doom could be just around the corner. This is your last chance to avoid spoilers, so read on at your own risk.

It seems that the DCEU could be in store for big changes, which could lead to the Legion of Doom coming together on the big screen. While Justice League didn't post the massive second-weekend drop that both Batman v Superman and Justice League did, it still had the worst box office debut in DCEU history, earning $93.8 million, which, to put in some perspective, is less than the debuts of 11 of the 17 Marvel Cinematic Universe movies. There will particularly be spoilers for one of the post-credit scenes, which apparently could have a big impact on DC's movie universe as it now stands. For those of you who haven't seen Justice League yet, there will be SPOILERS below for that movie, and the future of the DCEU as a whole.
