8 years before DC dared to try it in print, Hanna-Barbera presented the coda, the final episode of Super Powers Team: Galactic Guardians, in which Superman dies----for about half the show, anyway.
"The Death of Superman" comes across much better than the contrivance conceived at DC in 1993, as this would be the last meeting between the Super Powers Team (formerly the Super Friends) and Darkseid. This was the 8th and final broadcast in the series, as the episodes would continue to cycle through for the rest of the season before ABC cancelled the series, ending the Super Friends franchise after 13 seasons.
This episode would also mark the end of Danny Dark's run as the voice of Superman. When the Man of Steel returned in 1988, Beau Weaver was at the microphone, and that, as we've documented, lasted just one season.
