ToyFare contributor, Poester and vintage toys superfan Ben Leach pointed me to this post at Lounge Grayskull, featuring photos of a full-size, real-life Land Shark from Masters of the Universe, which is being restored to unholy life by Unique Movie Cars Las Vegas.

Says the poster:

The reason I am posting this is because I own and I am restoring a full size Landshark.I have check the movie they made in the 80’s and in was not in it.Does anybody know why mattel built this or what it was use for.I have posted a pic so everyone can see it. Any help would be great thanks…. YES THE MOUTH MOVES WHILE YOU ARE DRIVING

The fact that the mouth moves while driving is easily the most insanely awesome thing ever to be featured on a car, and yes, that includes the soothing voice of William Daniels. The most insanely pimped-out hydraulics-propelled gangsta car imaginable holds nothing on a giant purple chomping shark-car.

But there’s still a mystery here–when was this built, and why? Anyone know? UMC seems pretty sure Mattel commissioned it.
