Remember that third season episode where the Decepticons form a search party to look for the missing Galvatron, and who ends up joining the party but Galvatron himself? Ya gotta love those animation errors!
I enjoyed the 'toon for what it was, although I felt the various explanations did drag on a bit too long. To be honest I'm not surprised about the ending; I recall Starscream's nullrays being specifically designed to take out sources of electricity, so certainly it should affect even the mightiest of Decepticons.
