The only good feature, I think, on any of the first three box DVD sets that are out so far, is the special feature in season 1 volume 2 because they interviewed three cast members, Peter Newman, Larry Kenney, and Lynne Lipton. I just think it's the coolest thing to see what these people who voiced such beloved characters really look like. Peter surprised me. I expected someone much older since Tygra was one of the oldest ThunderCats. He sounded old! So I was shocked to see him look so young! He must have been in his 20's when he worked for the show back in the 80's.
