The Toyman's Super-Toy - S2.E10

The Toyman constructs an enormous remote control robot insect. He test flies it over a zoo and scares the animals. When Superman arrives to stop the insect, the Toyman purposely destroys it. He constructs another and gives it the capacity to produce Kryptonite rays out of its eyes. He sends the robot after Superman, but Superman successfully destroys it by using lead to sheild himself from the Kryptonite radiation.
