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.

Drew currently drives Podzilla, the resident monster truck at Santa Pod Raceway in the UK.
