Tony first seems to be every parent's dream: he is very handsome, one of the most popular boys in his town, does very well in school, and many of the girls in his town would give anything to date him. On the Skins website, in a MySpace-style "about me" section, he explains that his favorite philosopher is David Hume, his favorite medieval king is Charlemagne, his favorite Primal Scream album is Vanishing Point and that his favorite food is potatoes.

There is a dark side to his personality, however. The flip side of Tony's charm and self-confidence is an arrogant belief in his own superiority, but no one seems to notice. Teachers, friends, parents, schoolmates and girls all idolise him, despite his sociopathic tendencies - the cruel games he plays with his family and friends, in particular those closest to him, his girlfriend Michelle Richardson and best friend Sid Jenkins. Only those closest to him come to realise his true nature. In Sid, he displays his love for "control and manipulation" and fondness for the unpredictability of the universe, comparing the lives of those around to him to the functions of subatomic particles.

In the Unseen Skins episode The Cat and the Duck, his girlfriend Michelle characterizes Tony as like ice, "cold and transparent." It is unknown exactly what caused Tony to be the way he is. His parents are very loving (with the exception of his father's tirades), he gets whatever he wants, and many people appreciate and love him.

Tony's sexual encounters are vast. In Michelle, Jal Fazer is able to recall a long list of his conquests. Michelle later puts to Abigail Stock that he "fucks everyone... including boys." In Anwar and Maxxie, Tony attempts an oral tryst with his gay friend Maxxie. It is unknown if he is truly bisexual, as he says that he simply wants "to try something new", and that he never showed sexual interest in any other men before or after Maxxie. In a psychology lesson, he equates sex with power and his lust for both is portrayed in his presentation.

Tony's reading habits give insight into his personality. In Tony, the book he reads in the bathroom is La Nausee by Jean-Paul Sartre, a novel about existentialism and defining oneself. In Sid, he is shown reading Friedrich Nietzsche's Thus Spoke Zarathustra, a book which challenges existing moral values. In Maxxie and Anwar he reads Jeanette Winterson's Oranges Are Not the Only Fruit, a book about a young girl struggling with her homosexuality. In the Tony episode of series 2, he is seen reading Ayn Rand's Atlas Shrugged, while sitting on the train
