Name: Navistar MaxxPro
Type of Apocalypse: Military Industrial Apocalypse
Why: The Navistar MaxxPro is the US military's Mine Resistant Ambush Protected vehicle, or MRAP. Essentially it's an enormous armor plated truck with a blast force dissipating V-shaped floor, perfect for pretty much any form of apocalypse which doesn't involve scarce natural resources. The MaxxPro would make ruling on high like Lord Humongous a matter of principle, plus it's just incredibly badass. And if worse comes to worse, it can also transform into a Decepticon.
