Story Role

Maine initially expects to receive the military-grade Sandevistan acquired by Gloria Martinez. When he discovers that David has installed it himself, the resulting confrontation ultimately leads to David joining his crew rather than surrendering the implant.

Maine becomes David's principal mentor in the edgerunner profession. He gives him work, teaches him how Night City's mercenary world operates and encourages him to develop into someone capable of surviving it.

Maine's increasingly extensive cyberware eventually contributes to cyberpsychosis. During the disastrous operation involving Tanaka, his condition deteriorates beyond the crew's ability to control. Dorio is killed while trying to reach him, and Maine dies during the ensuing confrontation with Trauma Team and the NCPD. His death leaves David to inherit both his cyberarm and his position as a crew leader.
