So here is what's in my Brain now.
G1 Cartoon episode.
We open with the Decepticons raiding a power plant for energy. Soundwave dispatches the tapes to fill the Energon Cubes but unexpectedly the human workers, knowing the Autobots will be coming, stand up to them and by sheer numbers prevent them from filling the cubes until the Bots arrive, and the Cons are quickly forced to retreat.
Back at Decepticon HQ Rumble is complaining loudly that the humans weren't afraid of them anymore. Megatron says
"Then we will build NEW Decepticons they WILL fear! Soundwave, find out what humans fear!"
Soundwave flips through a bunch of channels quickly on the main view screen and settles on an old man in a goofy costume: "Welcome to our All Night Classic Movie Monster Marathon! Where all your biggest fears come alive" the man cackles and the screen flips through Black and White shots of Dracula, Frankenstein, Wolfman, etc... while Soundwave watches.
Cue the construction of Draculus, Frankentron and whoever else. The "Monstercons" are born!
-ZacWilliam, wishes we got things like Halloween Special cartoons cause I'd absolutely watch this one.
