from the Real World
Harvey Birdman, Attorney at Law is a television show on Cartoon Network. It has had references to the Super Friends series at times, and Apache Chief and Black Vulcan have even been seen as recurring characters.
Apache Chief and Black Vulcan appear as fired Super Friends. "They SAID it was some sort of budget thing, but I think it's because I complained that they were always pairin' me up with a white Super Friend; like I was gonna start super-lootin' the minute they weren't watchin'! And you think I named MYSELF 'Black Vulcan'? HELL NO! I used to go by 'Supervolt'! 'Black Vulcan' was Aquaman's idea. And I said, well maybe we should call you 'White Fish'!"
In "Very Personal Injury", Zan of the Wonder Twins is called in as a witness, explaining how Apache Chief came to rescue people when Wonder Woman was taking a personal day. He then explains he knows this because he was Wonder Woman's bathwater. A flashback is shown of Wonder Woman taking a bath, with Zan saying "form of... loufa"
