Yeah, you read that title right. But before you call Mumm-Ra a pedobear, you will be relieved to learn that the Kits are (thankfully!) young adults in this story, thanks to a good ol' fashioned timeskip.
Before the franchise reboot, Wildstorm released some limited series Thudercats comics. The second series, called "The Return" was controversial in that it implied that WilyKat & WilyKit are Mumm-Ra's sexy play things. Why else would they be parading around all chained up, in skimpy clothing. I think they look great, but I feel that part of my childhood died when I read this comic. It was so much darker than the cartoon.
