The Avenger is a motorcycle in Grand Theft Auto: Liberty City Stories, which is given as a reward to Toni Cipriani for completing 15 levels of the Avenging Angels mission in Portland. It will appear at the Portland safehouse. The color scheme may be related to those of Iron Man (red and gold) for he is one of the Avengers in the Marvel universe. The Avenger is bulletproof as well as fireproof and can only be obtained once in the game. If the player wants to keep this vehicle, he/she should store it in a garage.
The top speed, acceleration and handling are considerably better than the other chopper bikes of the 3D Universe, the Angel and the Freeway. It is, as aforementioned, bulletproof and fireproof, so the only way it can be damaged is through collisions or firing a Rocket Launcher at it.
