Master Cylinder
The Master Cylinder was an evil robot that appeared as a major antagonist in the 1960 Felix the Cat cartoon "Master Cylinder - Master of the Moon" (where he calls himself "King of the Moon") and he first appeared in Joe Oriolo's 1959 revival of Felix the Cat, he would then proceed to become one of Felix's main enemies throughout the series: unlike the Professor, Master Cylinder was never helpful nor friendly to Felix in any of his appearances and remained villainous (while The Professor often switched between the role of an antagonist and an uneasy ally). In his first appearance, he was defeated by being unplugged. He overcame this weakness by gaining feet and operating with a different power source. He can extend his arms, fly, and shoot lazers from the yellow rectangle on his forehead.
