Zor is one with the shadows, both physically and mentally. Believing that everything is pointless in the cosmic scheme of things, Zor has given up on hope, happiness and life. As such, he is constantly depressed, moody, rude, and mean, and is not impressed by anything. He often whines about the meaninglessness of everything and always has low expectations. This conviction also gives him a suicidal attitude, given that he once exclaimed that he "longs for death's cold embrace."

Despite his nihilistic perspective, Zor still intends to go through with his assignments, though he does not know why and has no interest in the outcome. Ironically, he does not like to hear others whine, as he wants that to be what he does, and he tends to give some things more value than others.

Zor has an extreme dislike for happiness in general, believing that it is such views that wreck the world for others. He becomes sick in the face of positive attitudes and gets pains in his face when smiling. As such, he will personally take action himself to ruin others' happiness. He has also displayed a masochist side of himself, finding comfort and even joy (despite his aversion to it) in the pain he receives, and when he does smile, thereby causing himself pain, Zor finds it cool.

like the other members of the Deadly Six, Zor is inherently malicious, sadistic and violent. Despite not being particularly violent (compared to the other Deadly Six) and claiming that nothing makes him happy, Zor enjoys the sadness and misery of others. He enjoys giving others bad news, making lives a misery, inflicting pain and physical punishment, and even killing others, which are some of the few things that can make him smile. An omnicidal monster, he has no qualms about causing global genocide for his own benefits. Zor also comes off as vengeful, given that once he was freed from Eggman's enslavement, he launched an attack on the scientist.

His personality takes a drastic turn in "Sonic X Dimensions", where after obtaining the element of Joy, he beings to see the folly of how he's lived his life prior, becoming happy for the first time in his life. now seeking pleasure above all else, he almost abandons the Zeti when he realizes that being a villain is the source of his depression,
