Troy's personality is based off of that of Dil Pickles from the Rugrats spin-off series All Grown Up!. He is a very odd child, believing in aliens and enjoys standing on his head for some reason (commenting that he feels all the blood rushing to his head).
Upon meeting his step-cousins (the McReary siblings) in his debut appearance, he believes Packie is an alien and asks him where did he come from. His older brother Adrian then enters the room and tells Troy to leave Packie alone. Troy is also shown to have a crush on Kate, but he is rejected due to them being legally related, and also due to the fact that Kate already has a boyfriend.
