Nothing is known about Proctor Nine's life before outbreak began. He was presumably a member of a biker gang known as "the Proctors".
Proctor Nine is among the gang members to prepare their vehicles for the journey to the Gonzalez Dam in Tijuana. He is questioned by Troy Otto, who is trying to investigate what the Proctors are up to. Later, Proctor Nine is among the Proctors to attack the dam.
Proctor Nine is seen with Proctor John, when he shoots Lola dead and discovers Strand trying to smuggle Madison and Nick. Proctor Nine recognizes Nick from the trading post and recalls that he was with another man. John decides to kill Nick, who he deems untrustworthy, and must therefore also kill Madison and Alicia, knowing they'll seek revenge for Nick's murder.
Nick threatens to detonate the explosives unless John allows Madison, Alicia and Strand to escape. Alicia urges Nick to come with them, but John points out that Nick cannot leave the detonator’s range. Nick calls the negotiations his "suicide note". John agrees to his conditions.
John realizes that Nick cannot detonate the explosives until his family is out of range of the explosion. His men close in on Nick. Suddenly, a shot rings out. Walker and Crazy Dog snipe at John's men from a distance, killing Proctor Nine and more.
