Not sure if being serious or joking, but history lesson inbound nonetheless.
^^^^^^^That is Nitro Machine (formerly Grave Digger #3, aka Dennis' first tube chassis truck), it came about due to the sponsorship Monster Jam had with World Championship Wrestling and it ran for 2 seasons under that name. However, the name went away after WCW went out of business in 2001 as did the Sting and Goldberg names. The nWo name was also used during this time but it went away after just 1 season, Matter of fact, the one WCW related name that still runs to this day is Madusa, and the main reason for that is because Debra Miceli (aka Madusa) owns the rights to the name. Once the Nitro Machine name was shelved, the truck ran mostly under the name Inferno, but it did dawn a few other names here and there before the truck itself was retired and supposedly scrapped.
Btw, here's a pic of it back in it's glory days as Grave Digger.
