Timmy Vermicelli is the most notorious and dangerous NPC in Driver. Killing 10 of them on each city, rewards you a bonus. He is a parody of the protagonist from the popular videogame Grand Theft Auto: Vice City, Tommy Vercetti. His outfit and looks are similar to Tommy except he has water wings on his arms. This is a joke pointing at the fact that you couldn't swim in Grand Theft Auto: Vice City.
Just like the other criminals in Driv3r, he will shoot you if he sees you or if you are too close to him. He will not walk around the map, no matter what, he will stay at his spot until he sees you and let him walk to you, getting him out of his spot, with the exceptions on some spots where Timmy will never move, no matter what.
Timmy Vermicelli will also attack Police on sight which a short gunfight will ensue, highly likely ending up Police being killed unless multiple police officers are already on sight or you help them. Timmy Vermicelli can be killed by police officers easily if they are armed with Shotguns.
Strangely enough, Timmy Vermicelli will also shoot other criminals.
