Though the Mongols are a smaller gang than many of their peers with similar notoriety, they make up for their relatively small numbers with tenacity. Since their 800-member ranks are clustered largely in and around Southern California, the MC is a powerful force there.
Founded in 1936, The Outlaws are thought to be the world's oldest outlaw motorcycle club. The Outlaws remain a strong presence today, with over 1,700 members across 176 chapters. While a number of MCs vie for control of Mexico-America drug trafficking, the Outlaws have maintained a substantial influence over drugs crossing the Canadian border.
The Pagans have grown through merging with other smaller outlaw motorcycle gangs. Considered by law enforcement to be almost as complex and diversified as the Hells Angels, the discipline and structure of the Pagans is the most rigid of the Big Four motorcycle clubs.
Vagos MC is best known for coordinating drug smuggling operations with their Mexican chapters. Founded in the 1960s along with many of the best known one-percent gangs, Vagos has been at war on and off with the Hell's Angels since the beginning. The Vagos were involved in one of the more interesting police operations in recent MC memory.
