- "See, I'm not an adrenaline junkie, I'm a control junkie."
- ―Dom Beasley
Dom is constantly seen engaging in high-risk activities such as skydiving and racing dirtbikes. His day job is as a hedge fund manager, and he is equally competitive and egotistical in both settings.
Not much is known about Dom's life prior to the events of the game, only a few things are mentioned across the storyline. At some point in his life, he met Glenn Scoville, who became a adrenaline junkie like Dom, thanks to his influence, as mentioned by Glenn himself to Trevor during his Bail Bond mission. He also has an illegitimate daughter with a woman named Karen Lichti, who posts on his Lifeinvader page in an attempt to track him down. Dom makes a reference to his daughter in the bike race down Mount Chiliad, where he taunts Franklin by saying that Franklin "rides slower than [his] daughter - and [he] hasn't even met the girl".
Events of GTA Online
Throughout GTA Online, Dom will contact the player by mobile phone, inviting him to extreme base jump events located at the "Parachute" markers on the map. Each call will involve him bragging about how he either has or is about to pull off a parachute jump before inviting the player to complete it with him. After the call, a specific Parachuting waypoint will be highlighted.
Events of GTA V
Franklin Clinton is introduced to Dom during Risk Assessment, when a dog (that Franklin converses with, and only he ever sees) leads Franklin to Dom, who is tied up after crashing his parachute into a tree, which Franklin untangles him from.
Immediately after being rescued, Dom pressures Franklin into parachuting with him. Franklin acquiesces to his demands, and Dom leads him to his helicopter, where his awaiting pilot, Jeff, flies them to 10,000 feet, and Dom and Franklin parachute to the summit of Mount Chiliad. Unknown to Franklin, Dom had planned a bike race between them, and had bikes left on the summit of Mount Chiliad, so the pair could have a race down the mountain. Completing this mission unlocks the Parachute Jumps throughout San Andreas.
After this, Dom tells Franklin to meet him at Los Santos International Airport. Meeting him there will start the mission Liquidity Risk, where Dom has two ATVs, which he and Franklin drive into a Cargo Plane. The Cargo Plane then flies over the Alamo Sea, and Dom and Franklin drive their Quad Bikes out of it to engage in another one of Dom's crazy stunts.
A while after that, Dom will send Franklin a text telling him that he free-climbed the Maze Bank Tower and is waiting on the roof for Franklin. Meeting him there will start the Targeted Risk mission, where Dom and Franklin parachute from the Maze Bank Tower onto a moving Flatbed truck.
- Dom's death is somewhat ironic, as during the helicopter flight in Risk Assessment, he lectures Franklin about how all jumpers must check their own parachute.
- His death is reported in the Daily Globe by Forrest Simon.
- If called in GTA Online or GTA V, his answer message will be: "You've reached the Dominator. Call back when I'm not making history".
- Dom can be seen parachute jumping in the introductory video of the Skydiving and Drop Zone lessons of the Flight School.
- Before dying, Dom starts panicking right after jumping from the top of the dam. It can suggest that he realized that Franklin was right about trying to warn him.
