Truckasaurus

Truckasaurus is a giant mechanical truck/dinosaur. It was created by Leo G. Clark. It is described as "20 tons and four stories of car-crunching, fire-breathing, prehistoric insanity".

History
The Simpson family went to see Truckasaurus but accidentally drove into the stadium where was it destroying cars. It grabbed the Simpsons' car and tried to crush it in its jaws, almost killing the family. The owner of the robot paid for the damage.

In Truckasaurus: The Movie he is called "John Truckasaurus" and is voiced by Marlon Brando.

A new version of the Truckasaurus, Truckasaurus II, was built for the Springfield Demolition Derby, but was destroyed immediately.

Comics
Truckasaurus ended up in The Auto Graveyard, where it fell into the hands of Bart Simpson, who accidentally turned it on, causing it to run amok in Springfield. It walked into Springfield Harbor and was never seen again.

The Simpsons Road Rage
The Truckasaurus is found in a stadium repeatedly smashing the same car while surrounded by mascots for the Springfield Isotopes.

The Simpsons: Hit & Run
Truckasaurus was created by Professor Frink. It is powered by copies of Bonestorm II, a WWII radio, a satellite dish and a blender. It cannot function properly with too many people in cars using cell phones. Bart helps Frink build the Truckasaurus and tests its destructive ability in his car.

Behind the Laughter
