Just as the title says, what do you think is the single worst series episode in Transformers history? One that fails in all three catagories: Animation Voice talents (or lack thereof) plot For me, I'd say it was the Energon epidoed where all the characters new and old fought eachother in the virtual fight ring. The Japanese version was okay but the english dub was JUST HORRIBLE! It's like the voice actors had no idea what was going on. Either that or >insert G1 season three episode hear<.
