As a person, Cyborg is a very outspoken and fun-loving character who likes to enjoy life, especially since he found friends who consider him a person, not a freak. He likes to enjoy playing video games, tinkering with technological gizmos and eating. He also tends to be stubborn and has had some serious arguments with Robin in the past, but he does make a capable second-in-command in Robin's absence. He also frequently bickers with Beast Boy, mostly about the latter's culinary taste and habit of misplacing all manners of personal items, though the two entertain a close friendship.

He takes on the protective big brother role to Raven and Starfire, getting quite upset when they get sad and tries his best to comfort them when he can. He hates losing battles, especially to seemingly insignifcant opponents, and has been known to display emotions of anger (which he often takes out on his friends) frustration, and becoming depressed. What emotions he feels he feels deeply and passionately, but he also has a mature head on his shoulders at times, shown partly in how quick he is to forgive Terra after her sacrifice.

One facet of personal vulnerability is Cyborg's great personal pride in his inventions and constructions. For this reason, he tends to foster an immense dislike for anyone abusing his technology for selfish reasons, especially Gizmo and Brother Blood, and to be overprotective of his most personal projects, like the T-Car.

He also possesses a tremendous appetite, and he will consume any edibles within his reach when hungry. His favorite food is barbecue and he also especially enjoys other meat, milkshakes, pizza, and waffles. The only food he would not voluntarily touch is Starfire's cooking and tofu (especially since Beast Boy goes to great lengths to try and make him eat it) although he once mistakenly ate the alien meat subsitute.
