LB is an unseen character in the Grand Theft Auto series who features as a minor character in Grand Theft Auto: San Andreas.
LB is an associate of Grove Street Families gang member Ryder. Ryder describes how LB told him about the firearms owned by Colonel Fuhrberger, which he and Carl Johnson steal and take to LB's lock-up in Playa del Seville. Ryder also mentions him during the mission Robbing Uncle Sam, describing him as "real reliable" and "a clockwork ninja". His lock-up is also used during the burglary side missions as a drop-off point for stolen goods, suggesting that he could be somewhat involved in the black market.
