Thundercats is by far the best cartoon ever made. It mixed fantasy with science fiction in an action/adventure format, using humor to keep it real while promoting moral and ethical values. It was among the first to ever use a child psychologist to make sure it would be suitable for kids while pleasing their parents.
It had the best voice actors in the business. Actors with multiple voice talent, they all played multiple characters and kids were none the wiser. The characters were relatable and kids could easily identify with Lion-O, Wilykit, and Wilykat especially.
It was also among the first cartoons in the USA to use anime, which for the 1980\'s, truly set this cartoon apart from the rest visually. It was an instant hit coming in at number one.
