C. Martin Croker

On September 17, 2016, Croker suddenly became ill, vomiting and developing a fever. Initially passing it off as food poisoning from consuming sushi, he asked his girlfriend to retrieve symptom relief medication from the store. When she returned to their home, less than an hour later, she found him unresponsive. She called an ambulance and performed CPR until paramedics arrived, where he was then pronounced dead. Croker was 54. No cause of death has been publicly given.

Adult Swim honored him by re-airing the first Space Ghost Coast to Coast episode produced, "Elevator", on September 19, 2016 as a special presentation. The tribute began with a brief description of Croker's contribution to Space Ghost and Adult Swim, with the words his character Zorak said in one episode: "Think of me when you look to the night sky", then the episode played. At the end of the episode, the screen shows "C. Martin Croker [1962-2016]". In the wake of the news of his death, Croker's friends and colleagues, such as his Coast to Coast friends George Lowe and Andy Merrill, paid tribute to him in posts on social media. Adult Swim made almost every episode of Space Ghost Coast to Coast available for free on their website in honor of him.

On September 24, 2016, Croker was honored at the beginning of Toonami in a segment in which T.O.M. receives a transmission from Moltar saying he's returning to his home planet and not returning, then boasting that he was the better Toonami host. T.O.M. wishes Moltar the best of luck and says "May your oven stay forever lit." An image of Croker was then shown, captioned "(1962-2016)".
