Found this on Deviant Art. Little inside to the previous incarnations of a thundercats series/movie.

Looking at the characters… Im glad it got “canned”
I sure hope they dont stray to far from the original designs in the revamp..
Chris here…
I actually think the character designs in these pieces look really good - however, the thing that I don’t like about these images is how dark and gritty they are, if this is how the TCats movie was going to look it seems as though it would’ve been a complete bloodbath! 
Take care… 
Great art indeed, reminds a bit of Frank Miller’s sketches, but i don’t think it’s fitting for Thundercats…
In the 4th pic why are there 2 moons side by side??
Where was supposed to be located:confused:
Oh yeah, I saw it too. Dave Bullock has a series of them and I looked at them all. They’re not in sequence, but I agree with Chris in that they are interesting to look at.
