And yes I agree that its pretty obvious Twilight is MLP's Hot Shot/Rodimus Prime character.
It's Hot Rod to Rodimus Prime on the Transformers Movie with Unicron, then Optimus eventually comes back to help fight the hate plaque by using the wisdom stored in the matrix. He came back in another episode, but that's a whole different story.
Anyways, watched the new episodes, good, but, as I said, it could've easily been a 3 or 4 parter. Easily.
