In another thread (http://thundercats.org/forums/index.php?threads/big-cheetara.1587/), He-Fan stated that there's a fact file listing Lion-O's height. I was wondering if there are similar details for the other characters, perhaps even including weight as well. I've been working off a model sheet that shows the principal characters -- one that has a line drawn at the top of Tygra's mane, which I presume is meant to indicate the six-foot mark. Based on that, and assuming that the crown of one's head is roughly five inches from the center of the eyes, I've calculated all the heights thus: 4ʹ1ʺ - Snarf (measured to top of ears) 4ʹ2½ʺ - WilyKit 4ʹ4½ʺ - WilyKat 4ʹ10ʺ - Lion-O (child) 5ʹ0ʺ - Mumm-Ra (mummy form) 5ʹ1ʺ - Jackalman (measured to top of ears) 5ʹ3ʺ - Monkian 5ʹ7ʺ - Slithe (measured to top of spines) 5ʹ7ʺ - Cheetara 5ʹ8½ʺ - Panthro 5ʹ9ʺ - Tygra 6ʹ0ʺ - Jaga (6ʹ6ʺ to crest of helmet) 6ʹ2ʺ - Lion-O (adult) 7ʹ5½ʺ - Mumm-Ra the Ever-Living (8ʹ2ʺ to crest of helmet) Though the publication He-Fan mentioned might not be as canon as the show, it's the only clearly-stated source I've heard of on the matter. It conflicts only slightly with the visual evidence I've been working with, and admittedly I don't know for certain that the line over Tygra's head means anything specific. Based on the stat he mentioned, I could scale them all down a bit. (If it's possible to upload images, I'll gladly share the one with the lines I've drawn on it.) What do you think? Edit: Updated with more accurate measurements!
