Clay Martin Croker (January 10, 1962 – September 17, 2016), generally credited as C. Martin Croker, was an American animator and voice actor.[1] He was best known for having provided the voices of Dr. Weird, Zorak, and Moltar on the animated series Space Ghost Coast to Coast, replacing Don Messick and Ted Cassidy respectively, who originally voiced the characters in the 1960s series Space Ghost.
On September 17, 2016, Croker suddenly became ill, vomiting and developing a fever. He believed it to be food poisoning from consuming sushi earlier in the day. After arriving home from an errand a few hours later, Croker's partner found him unresponsive, and he was pronounced dead by paramedics called to the residence minutes later; he was 54. No cause of death has been publicly given.
