Chuck Bell is the father of the two main characters, Josh and Jordan Bell. He is the main character from the Prequel to this book, but now he is all grown up. Throughout the story, he serves as a mentor to his kids, who are basketball stars. Chuck used to play basketball professionally overseas, and led his team to winning two Euroleague championships, earning him the nickname Da Man. Unfortunately, his pro basketball career was cut short because he refused to have surgery on his knee (he hated doctors). He constantly eats junk food like donuts and fried chicken, which led him to many health problems which became severe since he was avoiding the doctor. At the end of the book, he suffers a series of heart attacks and dies.
The story is told from the perspective of Josh Bell. Josh's passions consist of basketball and rapping. He is 13 years old. The nickname Filthy McNasty comes from the name of a song on one of his father's favorite albums. Josh is a basketball phenom. He used to have dreadlocks, but was forced to cut them off after losing a bet to his brother. Life becomes sad for Josh after his twin brother gets a girlfriend, as he barely spends time with him anymore. Also, during a game, out of anger, Josh threw a pass at his brother's face, almost breaking his nose. This causes the bond between the brothers to fall to an all time low, and Josh gets suspended from the basketball team. At the end of the story, on the same night his father dies, Josh returns to the team for the championship game and hits the buzzer beater to win it all.
Jordan Bell, twin brother of Josh, goes by the name JB. He is not as good as Josh at basketball, but he was still a star, as his jumpshot was cash. JB loves making bets, and will bet on almost anything. After becoming obsessed with a new girl at school, JB gets a girlfriend named Alexis. Because of this, he spends all of his time with her, and Josh becomes upset because he is lonely. JB balls out for the Reggie Lewis Junior High School Wildcats while his brother Josh was suspended for the altercation. At the end of the story, JB starts to accept Josh again because their father dies, and they realize they only have each other.
