The Lost Motorcycle Club is an outlaw motorcycle club in GTA IV. They are operating primarily out of Acter, Alderney City in the State of Alderney . The club's president (former vice president) Johnny Klebitz is the protagonist in The Lost and Damned. Their rivals are the Angels of Death.
According to the Lost website, the Lost began in 1964 with eight US marines who met in Hanoi, Vietnam. After the war ended, they had a continued thirst for drugs and violence. Because of this, they started the club and named it 'The Lost' in honour of all their friends who had been killed in the war.
