Yo got many gangs in Haiti.

Barbecue is the most well known leader, since he is more talking about revolution etc.
Also he formed the G9 alliance. An alliance of many gangs that are now under is control.

You also got the G-Pep alliance, who is the rival of G9, and his also an alliance of many gangs.
400 Mawozo is one of the biggest gang in Haiti, and is in the G-pep.

You also have smaller gangs that are not in those alliances but are well known and are very violent, like the gang 5 segond with his well know leader Izo.
Many of the smaller gangs have take the identity of bloods and crips, like the 5 segond gang who are crips.
The 5 segond gang are very violent, they cut the heads of two police officiers two years ago, it was viral on the social media.
The smaller gangs also have many rap videos on youtube.

Many of those gangs, members are ex-police officiers. And the smaller gangs that take the identities of bloods and crips, many of the members are criminals thats’ were exported from the United States or Canada, so they brought the bloods and crips culture in haiti.
