King Hiss gets a 9 from me, he was always one of my favourites. Although I've only owned the classic figure for about a year!
I liked the whole concept of the handsome friendly looking guy splitting apart to reveal a horrible monster. Had we seen a Third Season of the cartoon, I would have liked to see King Hiss as a rival villain to Skeletor.
I liked his 200x update even more, even though the figure wasn't the best, his characterisation in the cartoon as the more regal, sinister villain was great. Shame Zodak always had to be the one to beat him.
