A lazy slob who constantly rebels against his foster parents wishes and loves to play video games all day as well as sleep. Tough to break the ice and only goes by what his mind is on, which is either games, sleep, or snacking. He also breaks too much wind. However, during the P-2 Grand Prix, Quinton was forced to participate and use his Persona to fight his way through to stop it, much to his complaint. However, he learns more about himself of being a coward in life to face his problems rather than taking it head on, and being pushed further into denial until he finally reaches his limits in the battle against the fake Shadow of himself, with his stomach expanding amounts of gas due to sheer grief of his problems. Fortunately, after Codelio accepts himself and gains his Persona, as well as disposing the true culprit, Quinton goes back to being a slob, only different this time, no longer being the constant lazy guy (still lazy, though) and helps out his foster family from time to time as well as spending time with them. He still refuses to go to school.
