Ariel I can do.  Merida I can’t because I actually haven’t seen Brave (weird right?!)  Anyhow, here’s Ariel:

How I feel about this character:  I really like her, actually, one of my favorite princesses.  

All the people I ship romantically with this character:  Eric.  That’s about it, romantically anyway.  I could totally see her and Ursula though, a sort of one time being curious about the sea witch thing… actually, more than one time, Ursula showing her how to use that “body language” and all. 

My non-romantic OTP for this character:  Flounder and Sebastian are best buds for life, and Scuttle.  Though the ultimate is Sora (hahahahaha Kingdom Hearts yo!)

My unpopular opinion about this character:  I don’t think I actually have any…?  

One thing I wish would happen/had happen with this character in canon:  I’d be curious to see a take on it that sticks to the original story, which is much sadder.  I’d love to see it with GLBT undertones too, since it’s sort of a love letter from Hans Christian Anderson to Edvard Collin.
