Monstrous was a monster truck owned and driven by Drew Thornton in the UK and Europe. It was built by Nigel Morris's LA Supertrux. Drew performed at many of the same events as Nigel Morris in Bigfoot 17, and during Bigfoot's 30th anniversary in 2005, Drew ran the Bigfoot 30th Anniversary body on his truck.

At the EMTRC 2007 Helsinki event, the truck would have a crash which caused both front tires to break free from the truck. 

In 2008, the truck would retire. It was sold to a French operator and became Crusher.

Drew also drove Podzilla, the resident monster truck at Santa Pod Raceway in the UK before retiring and selling the truck to Garry Anderson.
