Both cinematic universes will find a powerful villain from another galaxy arrive on earth in order to collect a series of powerful objects (aka Infinity Stones and Mother Boxes).

Previously we saw how both Batman v Superman and Captain America: Civil War featured superhero team ups and infighting among the good guys.
Interestingly enough, this revelation is another case of the DCEU and MCU mirroring their stories.
