From the Superfriends episode SINBAD AND THE SPACE PIRATES. Captain Sinbad and his band of space pirates come to Earth and start plundering the treasures of an Incan temple in Peru, and hypnotize people with their hypnotic cannons to become part of the pirate crew. Later, Superman and Wonder Woman find Sinbad at his next treasure site at Stonehenge, but Superman gets sidetracked by stopping the large stones from hitting London, while Wonder Woman is captured and hypnotized. Wonder Woman now becomes part of the pirate crew, and serves aboard Sinbad's flag ship.
I re-edited this to where Wonder Woman remains brainwashed by the pirates.
