In 2005, Duck Dodgers returned to the world of DC (after the brilliant Green Loontern in 2003), this time paying homage to the Legion of Doom. Dodgers himself dreamed of himself donning a Superman-esque costume reminiscent of that worn years decades earlier in the Looney Tunes episode Stupor Duck - only the 'S' had been upgraded to a 'D.'
The adventure itself did not feature any actual DC characters, but the evil Roboto summoned together a horde of "13 of the most sinister villains" of Dodger's to form the fearsome Legion of Duck Doom.
Black Eel, nemesis of Sea-Man was one of my favorites owing in part his bubbly voice which channeled Black Manta. In all, a fun episode.
