- Author's Saving Throw: The fact that Victor presumably lost his genitalia, in the incident that led to him becoming Cyborg has always been a source of contention among fans, particularly African-American ones, with some likening it to castrastion. David Walker's short-lived run made a point of showing that Victor had begun regenerating the organic tissue that he'd previously lost, strongly implying that he'd regrown his genitals as well.
- Fandom Rivalry:
- Starting in late 2017, one formed between some fans of Cyborg and fans of Black Panther, due to the latter's solo film receiving way more support and hype in the black community than Cyborg's appearance in the Justice League film. Some fans have gone so far as to accuse Black Panther fans of being hypocrites for not supporting another high profile black character on film.
- As mentioned above, many Martian Manhunter fans dislike Cyborg for taking his place as the seventh founding member of the Justice League. This goes for fans of John Stewart as well, as they feel that John would have been a more logical choice for a more diverse founding member of the team, especially since the beloved Justice League animated series previously did just that.
- Replacement Scrappy: (After the New 52) While Cyborg is by no means hated in general, many preferred him as a member of the Teen Titans, and would rather have Martian Manhunter stay as a member of the Big 7.
- They Wasted a Perfectly Good Character: A common complaint with him after DC fully promoted Cyborg to an A-List character. Despite the attempts to treat him as a main hero, he lacked an ongoing when the New 52 launched, and his role in the Justice League was largely as Mr. Exposition and a Living Macguffin, with him being stripped of his ties to the Titans leaving Vic without any actual meaningful relationships outside of his father. Not helping matters is that his ongoings were forced to continuously retread the question of Cybernetics Eat Your Soul at the expense of building up any other stories.
