Retro Commercials Thundercats Toy Commercial 1 Lion-o and Mumm-Ra By Scotty Slasher - February 15, 2018 0 306 Facebook Twitter Google+ Pinterest WhatsApp I had both these Lion-o and Mumm-Ra figures. What I remember most is they were really solid and heavy. After awhile the eye glow ring would no longer work. =/ Also half human? I don’t remember that. Maybe they’re just describing how they look.
