Anthony "Tony" Clementina is the secondary antagonist of the Fillmore! episode "A Wurm in Our Midst". He was a delinquent student known for his criminal activities in X Middle School.
He was voiced by Frankie Muniz.
Tony first appeared bringing the local school shuffleboard team to his backyard as he previously stole their shuffle sticks since he intends to extort money in order for the team to get them back. However, Safety Patrol Officers Fillmore and Third caught wind of the scene and caught him, resulting him to serve detention for his actions.
When the books have been stolen from the X Middle School library, the duo found that the books have been checked out under fake library cards through bogus accounts. With this information, Fillmore and Third managed to track down Tony back to his home, where they found most of the books hidden inside his sister's treehouse and that he is creating copyright-infringed shirts. Because of this event, Tony is being faced with expulsion for committing the theft.
However, it turns out that Tony has a fear of heights, which is unlikely for himself to commit the deed if he were to use the treehouse to hide the books. Using the photos that were taken earlier in the crime scene, Fillmore and Third soon spotted dust particles covered under the left hand of Noah Hawthorne (the leader of the X Middle School Book Club) in one of the photos. This made them realize that Noah and the Book Club are the true culprits as they created bogus accounts and framed Tony to cover the tracks.
With this evidence, Fillmore and Third confronted Noah for the thefts, but he escaped into the hallways. However, Tony dropped a handheld video game on the floor, causing Noah to slip and allowing Fillmore and Third to nab him. While Noah and his fellow members are taken into custody and given detention and extra homework for their actions, Fillmore gives his apology towards Tony and offers to rectify this by giving Tony a job in creating t-shirts for the local softball team, a proposal that Tony happily accepted.
