Troy is a tanned human teenager. He wears a purple sweater with an orange sweater tied around his neck, white shorts with a cyan sweater tied around his waist, and cyan sunglasses. A lock of his otherwise brunette hair is bleached.
Like Carlton, Troy thinks he is more hardcore than Gumball and Darwin. Unlike Carlton, he does not speak so much, but can still be quite a bully with Carlton. Again like Carlton and his coach, Mr. Kreese, he is very ignorant as shown when he proceeds on fighting with Gumball and Darwin even after they admit that they are not hardcore at all, and becoming friends with them when they (the Wattersons) did nothing at all to earn his respect.
- "The Sweaters": His debut and first major role, he and Carlton challenge Gumball and Darwin to a tennis match.
- "The Spinoffs": He and Carlton summon several giant action figures to fight a monster.
