Yeah, I tend to like Water related characters from shows, and people with Water/Ice related powers or abilities...
I like Katara from Avatar: The Last Airbender
I simply LOVE Sailor Mercury from Sailor Moon.
I also like Sailor Neptune as well, as her attacks seem to be rooted in water more than Mercury, as Mercury was the soldier of Ice, but I still love them both.
And of course, our very own Misty from Pokemon!
