Benny is a major character in Gangstar Vegas. A man of muscle than of wits and he usually let's his boss do the talking and his fists do the talking. But treating him like a simple dog could prove to be a very risky gamble, no matter who you are.
However, Benny is paranoid that Frank would one day kill him, no matter what. He was at first Frank Veliano's right-hand man, his enforcer and the mountain of his henchmen; he later convinces Jason Malone to crash the Huevos' party while he kidnaps Karen. He is later arrested, after which Frank seeks to kill him so that Benny doesn't expose his deeds, while in police custody. Hope and redemption come for him when Jason rescues Benny from both the LVPD and the Velianos. He then joins his gang.
Benny keeps photos and documents regarding Frank and Winston Goodman committing illegal activities, such as bribery, debauchery and mass drug-dealing, in case Frank seeks to take him down; Jason later uses this weakness of Frank's to decrease the latter's power.
In the events of Gangstar Vegas
When Jason Malone knocks out Pietro Holston, Jason runs to his car while Frank and Benny chase after and shoot at him with their black Mi'kmaq SUV. After Jason is captured and forced to work for Frank, Benny uses Jason as his own pawn as well and orders him to do jobs Frank intended for Benny. Jason takes back one of Frank's Fruitfly-132 helicopters, which contains a USB stick with secret information from the airport that was confiscated by the police. Benny later calls Jason for help with eliminating some local gang members who are driving away, taking out a reporter with information about Frank, defending the Greek Phalanx from an attack using an assault rifle, and stealing crates from other gangs. While Jason plants some explosives at the Los Huevos' trailer, Benny retrieves a "package" that he and Jason deliver to Frank; it turns out to be Karen. Once Jason is able to triangulate Karen's location using some stolen military devices, he storms the City of Saints casino along with E-Man and Vera Montello and finds Benny holding Karen hostage. Benny refuses to obey Jason's demands to let Karen go, resulting in Jason beating him up.
Benny is later arrested, and Jason is persuaded by Karen to rescue him. Jason finds the police convoy being attacked by Frank's thugs. Jason rescues Benny and brings him to their base. Benny tells Jason that he has incriminating photos of Frank and Winston. Jason uses the photos to blackmail Goodman into exposing Frank. Benny last appears when he, Jason, and Karen are assualting Veliano's henchmen, who were supposed to fly Frank's helicopter away from Las Vegas. Benny tells Jason to carry a parachute with him before Jason takes off with the helicopter to confront Frank.
