- "It's business, fella. You wanna discuss it. We're at the farm."
- ― Elwood O'Neil
Elwood is a member of the redneck O'Neil brothers, and brother to several siblings, including Walton, Wynn, Ernie, Earl, Dale, Doyle, Daryl and Dan. The family was raised in a farm in Grapeseed, Blaine County, San Andreas, which they still use as a home and meth lab. The O'Neil brothers are involved in selling drugs and cooking meth, with Elwood serving as a leader to his brothers.
Events of GTA V
Rivaly with Trevor
- "I just spoke to that maniac Trevor. He's coming. Get down to the meth lab to protect it."
- ―Elwood informs his brother of Trevor's arrival.
The Los Santos Triads, who seek to expand their business in Blaine County, choose to partner with the O'Neil brothers instead of Trevor due to the latter's violent and reckless behaviour. After forcing Tao Cheng's translator to reveal that they're now working with the O'Neils, an enraged Trevor decides to destroy the O'Neil ranch as retribution for stealing his potential clients and ruining his dream of becoming an "international drug dealer and weapons trader". On the way to the farm, Trevor receives a call from Elwood, who tells him it was business and Trevor can come to discuss about the partnership at the farm, where all of the O'Neils are at the moment. But Trevor violently dismisses the offer and tells Elwood of his intentions to attack the farm.
Fearing of Trevor's attack, Elwood informs his brothers of the psychotic drug dealer's arrival, telling his family to protect the meth lab from Trevor, after which he drives away with Walton and Wynn to meet up with the Cheng family.
However, despite his family's best efforts, most of the O'Neil brothers (except Elwood, Walton and Wynn) are slaughtered by Trevor, who finishes his rampage against them by pouring gasoline in-and-outside the lab before blowing up the farm.
- "I'll be back to revenge myself."
- ―Elwood to Franklin, moments before his death.
Elwood and his two brothers eventually returned to the farm, only to discover it has been destroyed and their brothers dead. An enraged Elwood phoned Trevor, who is in Los Santos and threatened to kill him. Trevor, however brushed off the threat and gave away his location, while taunting Elwood. Elwood, Walton and Wynn then traveled to Los Santos and were about to fire anti-tank rockets at Trevor's safehouse only to learn from one of Trevor's roommates that Trevor has returned to Sandy Shores.
Elwood, Walton and Wynn later return to Sandy Shores to find Trevor, while being tailed by Trevor's associate Franklin Clinton on Trevor's request. The O'Neils discover Franklin and attempt to escape from him, but an elk on the road leads to their crash and subsequent escape into a forest, located somewhere in the Raton Canyon. Franklin then calls Trevor for help as he can't find the O'Neils. Trevor and his other associate Michael De Santa come with a Helicopter to help Franklin with the O'Neils.
Using a rifle, fitted with a thermal scope, Michael shoots Walton and Wynn dead, but can't get a clear image of Elwood, who is hiding behind a rock and fires rockets towards the helicopter. Elwood is found by Franklin, with the help of Chop, and attempts to run away, yelling at Franklin that he'll return to avenge his family, only to end up getting shot to death by Franklin.
