Adrian has been described as a normal, everyday child. He enjoys playing video games, listening to music, and playing/watching football. His favorite team is the Green Bay Packers. When his step-cousin Patrick "Packie" McReary first met him, Packie immediantly liked him, and the two (along with Packie's older brother Francis) enjoy hanging out and doing stuff together as a family.
By the events of The Next Chapter, Adrian and Packie are freshmen in high school, being the main characters of the series. Adrian has also joined the football team for the Fighting Trojans.
In the original series, Adrian was created to resemble Tommy Pickles in his All Grown Up! form. He has spiky hair that resembles Tommy's hairstyle, a shirt with stripes and sleeves, and basic pants and shoes.
