"Nightmare Planet", the Transformers, October 31, 1986
Daniel has nightmares.
It's a bit more complex than that, but lately Daniel has been plagued by nightmares of a giant Galvatron. It turns out the thing is a plot by the Quintessons. They're using Daniel's nightmares to create monsters to wipe out both Autobots and Decepticons.
This is proven when, on patrol, a tentacled monster attacks both the Autobots and Predacons. Springer and Razorclaw are both taken hostage. They find themselves in a fantasy castle, where they must work together to escape while Daniel's fantasy monsters wreck havoc on Cybertron.
Very rushed and you can tell, not to mention of all humans to use, why Daniel? And how big is his house that Rodimus Prime can easily walk around it?
