I prefer the old version! I was a child in the 80s and Lion-o was my first love! I created many alternative tales about Thundera, a promised marriage between Lion-o and Princess Onšana (me, a thunderian jaguar), and many other beautiful things who a little girl can dream... I think I still love Lion-o enough to write some fanfics ... maybe be forever! *pisk*
What I like most about in old version is the reddish color of the eyes. My eyes can reach that color in sunlight, and it make me feel a ThunderCat too!
Regarding the new Lion-o... he's sexy, but is not 'my' Lion-o!
I never actually saw the original version of the ThunderCats (I was born in 1995), but I've looked it up online, and I think the remake is much better (an interesting thing about the original Lion-O was that he was literally a boy in a man's body).
I'm an 80s baby, but I did see the original Thundercats series much better in the mid 90s when CN had Toonami on and shown it then. I have got to go with the more updated version. He looks much his age than what they made him to be in the OS.
