Peter Keefe, the creator and executive producer of the classic '80s TV series Voltron: Defender of the Universe, has died at 57. The cause was throat cancer, his brother tells the Times. Keefe, a Rochester native, created the series in 1984, cannibalizing the Japanese cartoons Beast King Go-Lion and Armored Fleet Dairugger XV, which he discovered at a merchandise licensing convention in Japan. After they ran out of footage from the Japanese shows, animators created new Voltron episodes from scratch. The series ran through 1987, becoming the No. 1 syndicated children’s show for two years, and inspiring several spin offs. "He ate, slept and drank Voltron," said Brian Lacey, his former business partner. And if you don't know about Voltron, that probably means we are old. You can catch up to the '80s on Hulu.
