It's long been discussed among forums such as these that MOTU shouldn't be the only '80s action figure line to return from the dead in the 21st century, and one of the top lines that always seems to come up is Thundercats. I've long speculated that Thundercats would have a hard time coming back because the company that held the license and made the toys, LJN, went out of business a decade ago and the license may have gotten bought or lost in legal mumbo jumbo.
Well, it turns out I was wrong and Thundercats will have a very hard time making a comeback because LJN wasn't the license-holder, they INVENTED the license to ride the popularity of MOTU! This is super-bad news because LJN went under hard and was torn asunder in bankruptcy issues, so for another company to bring Thundercats back to market, they'd have to track down ALL the creators and owners of the concept and get them to sign off allowing someone else to make these toys.
I am bummed, this line deserves to live again and it doesn't seem like it can.
