The Rollin Hundreds Crips consist of several gangs that fall under the Neighborhood card on the W/S of South Los Santos. All together, their turf stretches from 101st Street, to 120th Street. The gangs that make up the Hundreds are: Budlong Gangster Crips, 104 Hard Time Hustler Crips, 105 Underground Blocc Crips, 105 Gangster Crips, 107 Original Blocc Crips, 111 Neighborhood Crips, 113 Original Blocc Crips, 115 Neighborhood Crips, 115 Pimp Town Blocc Crips, 116 Acacia Blocc Hustler Crips, 117 Watergate Crips, and the 120 Raymond Avenue Crips. But in the late 2020's, the majority of the gangs under the Blocc card has been feuding with the 1e11um5 Neighborhood Crips due to shootings resulting in deaths on both sides.
UnderGround Blocc Crips (UGBC), also part of the
Blue Flame Gang (BFG), are one of the most active and historically notorious sets within the Rollin’ 100’s Neighborhood Crips. The set was originally founded in 1972 by a Mississippi born teenager,
William “Monk” Lee Johnson. Their roots trace back to 105th Street and Normandie Avenue in Westmont, South Central Los Santos. During the 1970s, their territory once stretched north toward Florence, but those areas were eventually taken over by rival sets such as 83 Gangster Crips, 99 Mafia Crips, and various Hoover gangs. Today, UGBC primarily claims 105th Street, while also holding presence on 103rd and 107th, with 105th being their most active and recognized clique. Within that area are the Normandie Manor apartments, considered a central hub where many members reside and operate from. Despite having a relatively small territory, UGBC is widely known for being highly active, militant, and consistently present on the streets, maintaining a strong reputation across the Westmont area. UGBC is closely allied with 107 Original Blocc Crips and 113 Original Blocc Crips under the Blue Flame Gang (BFG), also referred to as V8 Street. This alliance became even stronger following the death of Lil Blue Flame, who was killed by members of 99 Mafia Crips, intensifying long standing tensions. Together, these sets move with shared politics and tight coordination, making BFG a solid and respected alliance within the Rollin’ 100s... UGBC maintains long standing and active rivalries with multiple gangs. Their most notable beefs are with Hoover sets, particularly 107, 92, 94, 83, and 74 Hoovers. They are also in conflict with 99 Mafia Crips, Inglewood Families Gangster Bloods, Crenshaw Mafia Gangster Bloods, Avenue Piru Gang, and 83 Gangster Crips. Interestingly, they also have internal conflict within the Rollin’ 100’s, specifically with 111 and 115 Neighborhood Crips, who are located on the opposite side of Western Avenue. This rivalry is known to be especially active and ongoing.

Original Blocc Crips are a highly reputable but relatively niche Crip card that started in 70s in the Westmont district of South Central Los Santos, better known as the “100’s.” Established by three core sets:
107 Original Blocc Crips (107OBC), 113 Original Blocc Crips (113OBC), and UnderGround Blocc Crips (UGBC).. Who today are closely tied together under the Blue Flame Gang alliance (BFG) or Fleezy Gang. While primarily rooted in the Rollin’ 100’s Neighborhood Crips (RHC), the Blocc Crip identity stands as its own separate entity within gang culture, even though it is often associated with or confused with the Neighborhood Crips card. The BC card is widely viewed as a more militant and aggressive, counterpart to the NHC. Despite havign smaller numbers, BC sets have built a reputation for high activity and violence. Westmont, which was historically recored as the place with highest murder rates in Los Santos County, earning the name "Death Alley" from Los Santos Times. Blocc Crips and Neighborhood Crips sets funcion side by side, they're even housed together in county jail system, there are rare cases of internal conflicts. One of the most known rivarlies at the moment is between 111/115 Neighborhood Crips (OEF) and BFG aligned sets (UGBC, 107/113OBC). Historically, the Blocc Crips’ earliest and most consistent enemies have been the Hoover gangs, especially in areas overlapping with the Rollin’ 100’s. One of the first documented incidents between the two dates back to 1979, when 107 Hoover Criminals gang member Andre “Lil Ani” Jones was killed by UGBC members, marking the beginning of a decades-long and deeply rooted rivalry. This hostility has continued through the years, shaping much of the violence in the area.

West Side Budlong Gangster Crips (BLGC) began as an independent Gangster Crip (GC) set based around Budlong Avenue in the West Adams / Exposition Park area of South Los Angeles. They emerged in the 1980s and 1990s, building a reputation for street dominance and a strong GC identity. By 2004–2005, due to close ties with Underground Blocc Crips (UGBC) and Hard Time Hustler Crips (HTHC), and their longstanding rivalry with 83 Gangster Crips (83GC),
BLGC officially joined the Rollin’ 100’s, shifting from the traditional GC card to a 2X Rollin’ 100’s affiliation. Despite this change, they maintained aggressive control over their local neighborhood and became known for consistent beefs across South LS.
