Havent seen one of those in awhile on the bay, starting bid is 45
How DARE you… Just kidding lol. Looks like the Thundercats alright, I also think It suppose to have come with a round shield and some weird looking facial cut out mask. It’s part of a set, sadly the set never came with the sword of omens though
The set came with the sword but it was different from the LJN version.
and very pricey.. I picked one up for $3 on ebay a few months back.. 
i had one of those as a kid. i also had a dagger sized Sword of Omens, but i dont remember if they came together or were bought seperately
