I'm happier with Ariel as a partner than a princess, as others have started before me, I'm not sure she'd fit the bill.Willing to make a deal with the devil, etc. Plus, it was cool to have her fighting there.
But, aren't almost all the Disney Princess wanting more? Like Riku did, they weren't super satisfied with their current situations... The way they went about changing it was almost identical, though. Asking scary ladies that they knew they couldn't trust for the power, that it.
