GTA VI World
This page covers only groups and crews Rockstar has named in official material or character bios. Rivalries, territories, and ranks are not invented — where the official record is silent, this page says so.
The only gang Rockstar has explicitly named in public material. Southside Vice City, hydroponic operation, Illegal Goods Store/compound; an Ultimate mission raids their compound for contraband.

Outlaw motorcycle club in Ambrosia. Rockstar's Ambrosia copy confirms a local biker gang's role ('the local biker gang provides almost everything else'); the club's name and 'est. 1982' are read from member patches in official screenshots and footage. No named members, no confirmed missions or business role.
