Martin Croker -
Croker abruptly died in his home in Atlanta, Georgia on September 17, 2016, at the age of 54.[3][4] No cause of death has been publicly given.[4]

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.[5] 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. After the episode aired, it showed "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 has made almost every episode of Space Ghost Coast to Coast available for free on their website in honor of him.[6]

On September 24, 2016, at the beginning of Toonami, TOM receives a transmission from Moltar, telling him that he's returning to his home planet and isn't coming back and then boasts that he was the better Toonami host. TOM then wishes Moltar the best of luck and says, "May your oven stay forever lit." It then shows an image of Croker, with the words "(1962-2016)".[7]
