Perhaps a victim of his own success, Aquaman went from headlining his own show in the 1960's to being lampooned alongside the Wonder Twins as the laughing stocks among the superheroes. I think that writers struggled with making Aquaman heroic as a member of the dry land dwelling Super Friends. After years of seeming useless, Aquaman became the butt of the joke and the topic of countless lazy fish puns. The culmination of mockery for the washed up King of Atlantis was in the form of Cartoon Network Latin America's 7 episode run of The Aquaman & Friends Action Hour in 2003.
Poor Aquaman went from battling undersea invaders and aliens on other planets to hosting a kids show with puppets.
