Okay, slightly dumb question, but on a recent reread of the book 'Good Omens', there's a joke where one of the the Them mixes up the Metatron with Megatron, and I was wondering if the figure that Pepper and Wensleydale are talking about actually existed or whether the authors had made it up. The book was published in 1990, so we're probably talking G1. The lightning vanished, and a young man made out of golden fire stood there. "Oh dear," said Aziraphale. "It's him." "Him who?" said Crowley. "The Voice of God," said the angel. "The Metatron." The Them stared. Then Pepper said, "No, it isn't. The Metatron's made of plastic and it's got laser cannon and it can turn into a helicopter." "That's the Cosmic Megatron," said Wensleydale weakly. "I had one, but the head fell off. I think this one is different."
