Unlike other cartoons, early advertising for ThunderCats was aimed at parents and explained the values that the show would be teaching children. Scripts were reviewed by a psychologist to ensure that these promises to parents were kept. Telepictures even created lesson plans for teachers to use in connection with the show.
In 1986, a visually-impaired character, Lynx-O, was added to ThunderCats. He was portrayed as wise and equal to the other Thundercats. Lynx-O’s addition also provided an opportunity to teach viewers about the Braille writing system.
