Katt Williams put a huge chunk of change down on an absolute beast of a vehicle ... one that's fittingly named after the end of days.
Katt recently purchased the Apocalypse Hellfire ... an eco-diesel truck with 6-wheel drive and Kevlar coating. The rims are fresh with custom purple powder, and it's got the leather interior color to match.
The "super truck" set Katt back $200K, but it's not the first time he's made a purchase like this -- he's worked with Apocalypse Manufacturing in the past, building 2 other trucks with them.
