The Lost MC

History
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 began the club and named it "The Lost" because of their friends who were killed in the war.

Alderney Chapter
At the beginning of The Lost and Damned, the protagonist Johnny Klebitz is the acting leader of in the absence of Billy Grey, who was been incarcerated for drug charges.

Prominent members of the Alderney chapter included the chapter's President Billy Grey; Vice President Johnny Klebitz; Treasurer/Lieutenant Jim Fitzgerald; Club Secretary/Lieutenant Brian Jeremy; Road Captain/Lieutenant Clay Simon and Sergeant-at-Arms/Lieutenant Terry Thorpe. Other noteworthy members were Jason Michaels and Angus Martin, as well as old ladies Leila Sharpe and Ashley Butler.

They are based on The Outlaws MC as Billy Grey at one point stated their motto is "the almighty forgives... the Lost don't", which is identical to that of the Outlaws. Another one of The Lost's slogans is "Brothers for life...Lost forever".

Even though he is a member of the Lost MC, after some of Brian's faction was killed in End of Chapter, Johnny considers them as Alderney pisslickers.

Liberty City Chapter
The Lost MC also has a chapter in Broker, Liberty City. In 2008, Johnny met up with six bikers from the Lost's Broker chapter on the Broker Bridge. Jason also called for help from the Broker chapter when hired gun Niko Bellic attacked him.

While there is no chapter in Algonquin, Johnny and other members of The Lost have been seen in Algonquin.
