Carey Mahoney is the leading main character of the first four movies and the animated series of Police Academy.
A troublemaker with a heart of gold whose worst habit is retaliating against insults in bizarrely effective ways. He is best known for protecting Commandant Lassard and playing practical jokes on Harris, Mauser, Proctor, Blankes and Copeland, as the five men view Mahoney to be unworthy of being a police officer due to his carefree attitude.
Despite his womanizing and his rule-breaking habit, Mahoney is portrayed as a good and courageous person willing to help those in need, regardless of the consequences. The valor Mahoney displays is likely stemmed from his father, and his graduation with a decoration for bravery speaks to that.
Mahoney comes from a family where his father was a decorated police officer,
Before his police career, Mahoney was a parking-lot attendant until he was forced to park an abusive customer's car in a full parking lot. So in response, he put the car into a side-wheelie, crashed it between two cars and proudly proclaimed, "It fits!" This bad act got him fired and arrested to which his father's former boss, Captain Reed gave him only two choices, jail time or the police academy to not insult his father's background.
By the third movie, Mahoney's dedication and love for his officer job are proven as he continually stands up for his cadets, and giving a speech highlighting how important the cadets are to the Academy and to his peers which inspires the cadets to work harder and achieve their potential.
In Police Academy 4 : Citizens On Patrol, Mahoney successfully lobbies to have two skateboarders, Arnie and Kyle, to be placed in the "Citizens on Patrol" program as an alternative to jail time, reminiscent of how Mahoney himself started in the Academy and had his life turn around for the better.
- Carey is shown to be a fan of the St.Louis Cardinals - at the party in the first movie, he is wearing a light blue #15 Cards jersey.
- In the animated series, Mahoney is almost present for every episode with his partner Jones (when in action). He is absent from the last three films, a change that is unexplained. According to the producers, he was originally in the script for the fifth film, but Guttenberg declined the part.
