Albert Clifford Slater (usually shortened to A.C. Slater, or just Slater) is the deuteragonist of the sitcom Saved by the Bell. He also appears in the spin-offs Saved by the Bell: The College Years and Saved by the Bell: The New Class (as a guest), as well as the 2020 reboot, where he's the Bayside football coach. Unlike Zack, Slater did not appear in Good Morning, Miss Bliss. Though, a character with many similarities to him named Mikey Gonzales appeared in the show, making Mikey a precursor of sorts.
Slater's best friends are Zack Morris, Kelly Kapowski, Jessica "Jessie" Spano, Samuel "Screech" Powers and Lisa Turtle.
Slater is the jock of the group, showing his love for sports and working out. He is shown to have a higher moral standard than Zack, but that doesn't stop him from playing his right-hand man in some of his schemes. On some occasions, he's also the main reason Zack pulls off his scheme, for instance when he bets on Zack to skip every class on cut day, where if Zack is caught doing so, he will get a suspension, due to having 9 previous unexcused absences. Another instance of this is when he bets on Zack that he can make Screech win the Bayside beauty pageant.
A.C. Slater is portrayed by Mario Lopez.
