Anyways, the cartoon features the Super Friends and the evil crew of bad guys known as the Legion of Doom. A bunch of the episodes kick it off panning a swamp scene that always has the same alligators. Then, from the depths of the murky waters rises the Legion of Doom's headquarters, the Hall of Doom...
It really looks like Darth Vader's helmet. I don't know for sure if the Hall of Doom was inspired by the Sith lord, but one would guess.
I've always wondered why the Legion of Doom even bothered leaving the concealing waters of the swamp just to hold a meeting. All they're really doing is blowing their location. Underwater would be a much better hiding spot.
Another weird Vader can be spotted on an episode of Super Friends: The Legendary Super Powers Show (it might have been "The Case of the Dreadful Dolls", I don't remember for sure). There's a pile of stuffed animals, including ET, the Jaws shark, and a yellow Darth Vader with lightsaber!
So how does any of this relate to collecting...? It doesn't really, sorry, but you can buy the Super Friends DVDs if you want.
