@ginger: Well, the villain for the first half of the series is never defeated until the final few rounds, and the villain for the second half
is an evil god who very nearly wins.
The protagonists actually lose about as often as they win, and the loses tend to be more devastating. The characters are pretty likable, the races are always awesome and the parts out of the races are great too. the animation is absolutely stellar, and the story itself is pretty awesome. It's a great searies, I downloaded it to watch a while ago and I pretty much burned through it in a few days.
Also the episodes titles were alliterative, yes, but they still followed a [verb/adjective] like [competitor] format, so that's why the videos reminded me of them.
I just can't help but imagine what each of the girls racer's would be like. I imagine applejack in some giant, tank-like monstrosity billowing smoke, Rarity in some crazy motorbike, and Dash with basically just a jetpack to accelerate her flight speed. and Twilight is pretty much like that wizard dude from the finals. Pinkie and Fluttershy are more questionable, but Shy is probably riding some kind of animal, like Aika did.
