Rockolizer

The Rockolizer was a hand-held gun-like device invented by Krang that could control all kinds of mineral objects, such as rocks, gravel, pebbles, concrete and asphalt etc. General Traag was tasked with using the device to control all mineral objects in New York in an effort to draw the Turtles out and destroy them while, Shredder, Bebop and Rocksteady break into the space station and plant a super laser on the space shuttle to free the Technodrome from it's Arctic trap.
