Marcus Burnett

Marcus has a wife, kids and a tight deadline: 72 hours to find $100 million in heroin stolen from the police. When the witness Julie will only talk to Mike, Captain Howard forces him to pose as his partner. He takes her to Mike's apartment while Mike lives in his house, and the lie falls apart when his wife Theresa finds out. Even so, in the final shootout he helps rescue Julie and goes home.

Eight years on, Marcus wants out of the narcotics squad. In the raid on the Klan meeting, Mike accidentally shoots him in the rear. He doesn't yet know his partner is dating his sister, Syd. When Syd is kidnapped, Marcus goes to Cuba with Mike and the team. In the minefield near Guantanamo, he is the one who shoots Tapia in the head, and he decides to stay Mike's partner.

Seventeen years later, Marcus watches his first grandson being born and decides to retire. Mike won't accept it, the two fall out, and Mike is shot. Marcus only returns when Captain Howard is killed, and he talks his partner into working with the AMMO team. He stands by Mike in Mexico City and, when Isabel's helicopter takes off, shoots the pilot and brings it down. In the end he accepts that the duo goes on.

At Mike's wedding reception, Marcus has a heart attack and falls into a coma. There he sees Captain Howard tell him it isn't his time. He wakes up convinced he can't die and starts taking absurd risks. With Mike, he tries to prove Howard wasn't corrupt, goes on the run and sees his family threatened. At the climax, McGrath holds him hostage with Christine, and Mike shoots his vest. Marcus breaks free and, thanks to his son-in-law Reggie, the family comes out unharmed.

Marcus Burnett is the comic voice of the duo. Martin Lawrence has played him since 1995, when he also starred in the TV series Martin. The original script was written for Dana Carvey and Jon Lovitz; Lawrence and Will Smith got the roles.
