- From looters to anarchists and everything in between. The Crazies are made up of all those who chose not to evacuate the City, who stood together in the face of Dusklite Security's overzealous 'protection'. They brought weapons from sports-store ruins and called open season on anyone who got in their way.

"The Crazies" refer to a faction of leftover citizens of the City in which MotorStorm: Apocalypse takes place. They oppose the incursion of DuskLite and MotorStormers into their city; they believe it to be their territory, and refuse to leave. Their clashes with DuskLite forces often serve as the backdrop for many of the most intense races in the game.
- Guns (predominantly assault rifles, such as AK-47)
- Molotov cocktails
- Rocket launchers
- Atlas Bobtails
- According to a Festival Card, the most prominently seen Crazy in cutscenes is named "Alfred J. Newbottom". He is voiced by Steve Blum.
- Atlas Bobtails used by the Crazies have unique parts, such as a rusted out variant of the second front bumper and exhaust pipes and a rear bumper that is not available in customisation.
- The rifles the Crazies use don't damage vehicles, so to speak, but they do speed along the overheating of your boost system. If you are already at critical boost and you pass by a group of rifle-wielding Crazies, then back off the boost ASAP, otherwise, you will explode. Their rocket launchers have a similar effect.
- Fuel tankers used by the Crazies have the "Rock Fuel" logo graffitied to read "RockERS".
- In E3 2010 footage and trailers, the Crazies sometimes used a strange vehicle that resembled a mobile home with parts of the rear half cut out to create a platform on which Crazies would stand; this vehicle is not in the final version of the game. The word 'CRAZY?' is graffitied on the side.
- The most common Crazy 'uniform' consists of a leather jacket with flames. Similar flaming skull stickers are included in the Outlaw Pack.
- Some Crazies wear sports helmets and padding, presumably as armour.
- Crazies can be seen piloting hot air balloons above The Rock.
