Cyborg has had many different looks over the years. When he first debuted, he looked like this:
By the New 52 (November 2011), he had a much bulkier, less humanoid look with red highlights. I don't like this style as much because, as a cyborg, I think his human parts should be about equal to his mechanical parts.
In the movie Justice League: Flashpoint Paradox (2013), Cyborg has the below look for the beginning of the movie. I like it a lot because it makes him look athletic - which he is - and shows that's he's mostly human with some modification. Unfortunately, he has an appearance similar to the one above for most of the movie.
Luckily, DC Rebirth happened and fixed a lot of the New 52's issues. In Convergence: Crime Syndicate #2 (May 2015), there's a Cyborg backup story where he loses both his arms. Then something happens - I'm not entirely sure what, even though I've read the pages - and he not only regrows his arms, but gets a whole new design more in line with the picture above. Silver and black with blue highlights, exposed upper arms, those blue baubles...it's not a 1-to-1 transfer (and these things usually aren't), but it's close enough to be noticeable. This backup story was to set up the ongoing series he got as part of Rebirth.
