The O'Neil Brothers
|Fronts:||The O'Neil Farm|
The O'Neil brothers are a gang in Grand Theft Auto V.
|Spoiler Warning: Plot and/or ending details are in the text which follows.|
A family of inbred rednecks, the O'Neil brothers are a meth manufacturing ring operating out of their farm in Grapeseed. They are in competition with Trevor Philips Enterprises, and until Trevor wiped them out, the Los Varrios Aztecas and The Lost Brotherhood.
In Crystal Maze, Trevor learns that Tao Cheng's father, Wei Cheng, plans to do businesses with the O'Neil Brothers instead of him. Furious, Trevor drives from the Yellow Jack Bar to the O'Neil Ranch, where he wipes out most of the O'Neil clan and destroys their ranch house by burning the meth lab in the basement. Some time after Trevor executes The Merryweather Heist, Elwood calls Trevor, threatening to find him and kill him. In Predator, the three surviving O'Neil Brothers go to Trevor's Vespucci Beach safehouse with an anti-tank rocket, only to find out from either Floyd Hebert or Wade Hebert that Trevor returned to Sandy Shores. When the O'Neil Brothers leave for Blaine County, they are tailed by Franklin Clinton and his dog Chop. During the chase, the O'Neils wreck their SUV when an elk runs out in front of them and flee on foot in the forest near Raton Canyon. Trevor, Franklin, and Michael De Santa track down and eliminate the remainder of the O'Neil clan.
