Slayerdesignstudio.net has some T-cat heads and torsos that are 3 3/4" that look like the original cartoon. These toys are good for kids, but old school guys will probably pass on these.
I saw those, the sculpts are very cool, true, I'm a fan of both the old and new thundercats, I almost passed on them myself, but I was like I will just buy lion'o, then fast forward a couple of weeks and now I have the whole set lol, but i think with repaints they could look real and not like cartoons, but it won't be me painting lol
