Cyborg's Accident and Evolution

Take this with a grain of salt. Apparently, the original plan was for Justice League to touch on the accident that set off Victor Stone’s transformation into Cyborg (in early trailers, he was seen playing football).

In the deleted scene, Victor’s driving home with his mother, angry because his father didn’t show up to support him – again. His mother tries to calm him, but he becomes even more angry, which is when the accident happens. Such a scene would have given us more information about the character, and his role as an outcast. In addition, it would have helped to explain his father's attempt to bring him back.

We know that the studio intended to explore Cyborg's evolution and discovery of his powers in Justice League. Days after the movie’s release, clips surfaced that had him going through the various stages of his transformation. He realizes that he’s developed new abilities, including that of controlling technology. The movie does include his discovery that he can fly, though.
