One of the most underrated writers of his day, Mr Starr wrote about a majority of the scripts for the Thundercats (1985) series and was the principal showrunner for the franchise. It was his past work in other comics and in very early Marvel (which was once called Timely Magazine), that showcased his work. Both Jack Kirby and Joe Simon (the latter, one of the creators of Superman) praised him highly.
He worked on two other comics, Mary Perkins on Stage and Annie – which the later he revived and continued until 2000. He also did work on the Kelly Green Graphic Novel with Stan Drake But most of us will know him as the Thundercats main writer and producer.
He was 89 years old.
