As the headline on the Daily Planet tells the public: "Mechanical Monster loots bank!" In fact, a scientist has an army of these flying robots able to steal anything in sight. Police are set up everywhere to guard an exhibition of rare jewels, but it's no use. When a robot crashes into the building, it steals all the precious stones in sight, while the policemen's bullets harm it no more than flies. Clark and Lois are at the exhibit. While Clark phones in the story from a booth, Lois stows away in the robot's compartment. Clark sees that Lois has gone missing and decides to change into Superman there in the phone booth. Superman follows the monster, while his X-ray vision allows him to spot Lois inside. His attempt to get Lois out fails. The robot knocks him onto some power lines, losing the jewelry and (nearly) Lois in the process. The robot returns to the scientist's hideout with Lois, but no jewelry. She refuses to tell the scientist where it is. He retaliates by tying her up and ... Written by J. Spurlin

Another great Superman cartoon
16 October 2004 | by (United States) – See all my reviews

Another mad scientist has constructed a bunch of giant robots to rob banks and jewelry for him. They also can transform themselves into planes and fly to their targets (!!!). Lois Lane hitches a ride on one of the robots. The scientist discovers her and is ready to boil her alive in lava. Superman has to rescue her but he's attacked by the scientists' multiple robots...

Another great animated short. I was surprised by the violence (you see a large bunch of policeman shooting at the giant and Superman takes quite a beating from the robots) but it's still perfect for kids. Also they show Superman using his X-Ray vision--that sequence alone was just unbelievable!

Fast, fun, full of action. Just great! A 10.
