ThunderCats - Season 1 Episode 18 Spitting Image
8.25 22 minutes Mumm-Ra creates device that can make Panthro clones. He embeds the spirit of Hammerhand into his clone and sets it free to destroy Third Earth. The Third Earth inhabitants blame the Thundercats for the terror because they think its the real Panthro destroying their villages and burning their crops. The real Panthro finally encounters his clone and, with the help of Lion-O, manages to destroy it. Enraged about his defeat, Hammerhand destroys Mumm-Ra's cloning device.
