Hello everyone! Now if you haven't watched [Batman v Superman: Dawn of Justice](tag:711870), and you don't want to be spoiled, DO NOT GO TO THIS ARTICLE. SPOILERS SPOILERS SPOILERS! I have warned you, also, I may be wrong at some points, and I am sorry If I am wrong with some of this. So let's start!
Cyborg (Victor Stone)
We could see Silas Stone trying to bring his son ( Victor Stone - Cyborg ) back to life after a terrible accident that destroyed half his body. We also see the "mother box" which you can hear Cyborg scream as his father Silas turns off the recording.
At this scene, we see an underwater drone camera(?) search some part of the ocean. As it headed deeper into this sort of black space, we see Aquaman. And.... well... he just basically destroys the camera.
So The Flash has two cameos in this film. It was really unexpected for me because I thought Aquaman will be a bigger portion of the cameos.
The First Cameo : The First Cameo starts with Bruce Wayne waking up from the Darkseid dream sequence ( We will head there later ). After the dream sequence, a portal comes out of nowhere, and The Flash appears with a "post-apocalyptic" armor, a nod to Injustice : Gods Among Us. So basically, in this first cameo, The Flash traveled back in time. He told Bruce Wayne that "Lois Lane is the key", "You were right about him", "Find us Bruce". This is probably another nod to Injustice : Gods Among Us, because there, Superman kills Lois Lane ( thinking she was Doomsday ) and kills the Joker, And rules the whole Earth. And, The Flash tells Bruce Wayne to find the other metahumans, obviously setting up the Justice League.
The Second Cameo: So here, Barry Allen is at a store, and moments later, the store was being robbed. At a "flash" (haha.) a streak of red light appears. We could see Barry move so fast that it looked like he didn't even move.
And that's all. I hope you guys enjoyed my review and take care.
