The following contains spoilers for Cyborg #1, on sale now from DC Comics.
Cyborg has been one of DC's most iconic heroes for decades, though it was mainly his portrayal in the Teen Titans cartoon that gave him mainstream stardom. This popularity made him a Justice League founder during the New 52 reboot, though the decision was incredibly controversial. While many fans have expected the change to be retconned again, it doesn't seem like that is the case.
Cyborg #1 (by Morgan Hampton and Tom Raney) takes a look back at the hero's past, and it involves events that many fans would rather forget. It also conjures up a lot of questions concerning Cyborg's current continuity status. And, given the fans' reaction toward the New 52 incarnation of Cyborg, this could definitely be bad for the character in the long run.
DC's New 52 Created Problems For Cyborg's Character
In the first issue of the series, Victor Stone battles Gizmo and Mammoth. After doing the villains in, he recalls how he became Cyborg and what he did with his life after. According to this retelling, he initially joined the Justice League upon being built into a human cyborg. Not quite fitting in, he would instead choose to join the Teen Titans, feeling more at home among heroes his own age. The flashback to this involves a glimpse of his days during the New Teen Titans book where he debuted. This establishes that at least some version of that history is back, though his ties to the Justice League complicate things.
Despite having a negligible at best connection to the team, Cyborg was retconned into being a Justice League founder during the New 52 continuity reboot. This made no sense, especially given how poorly utilized the change was. Many fans felt that it robbed both Cyborg and classic JLA member, Martian Manhunter, of their unique places in the DC Universe. It also didn't help that adaptations of the idea weren't successful. With DC Rebirth bringing several classic elements back into continuity, fans were desperate for the changes made to Cyborg's character to be erased. Unfortunately, this is seemingly being done in a confusing, half-hearted manner.
Cyborg's Justice League Affiliation Remains DC Canon
The first issue of his new book makes it clear that he wasn't a founding member of the Justice League, but it still muddles his history with the Titans. There's no way that the classic New Teen Titans run could have happened quite like fans remember if Victor Stone was on the Justice League. Likewise, it's clear from how this is handled that the writer wanted to sweep his tenure under the rug as much as possible. Even if this isn't the case, the fan reception toward Cyborg's treatment during the New 52 should be enough of a reason to do away with these elements completely.
It's also worth noting that during the events of The New Teen Titans, Victor's father Silas Stone died. In the new Cyborg series, however, he's portrayed as recently deceased. This cements that a lot of the classic stories didn't happen the way that fans remember, which is somewhat antithetical to the ideas behind both DC Rebirth and giving Cyborg his Titans history back. It would have been better to not contradict elements from the iconic run, let alone bring back things from the New 52 that simply didn't work.
