A batch of never-before-seen concept art from the original Thundercats series (and voice actor) Jim Meskimen shows us a whole new version of the space kitties from Thundera. Check out the original concept work on such oddball Thundercats characters such as Captain Cracker (and a handful that never made it to the screen).

For more images head over to the fan forum Thundercats.ws where these images were originally posted, there's plenty more.
