Definitely

Umm as a girl,I'll go with Katara because she's prettier.

Prettiest in the series.

I love the fire vs water thing. For me personally its Azula, but I'm a girl so...

Definitely.

^^ Same.

I love Katara more but let's face it, there is no contest. Azula is BY FAR prettier and is MUCH sexier! Katara looks 14 but Azula doesn't, despite that being her age. Before I found out her real age I thought she was Zuko's older sister. I mean, usually when the parent favors a sibling for being much more skilled, that child is usually the old sibling. I thought she was 17-19. She sure looks like it. Her face and body is developed like it. Puberty and nature was VERY kind to her in the looks department.

I thought she was the older sibling too at first.

Definitely!

definitely. although it would have been more fair to make the pictures similar- Azula has a fan art of her in a sexy bikini and pose while Katara's is from the show and is slightly more modest.

I would have but with all the fanart I saw of Katara they always gave her ridiculously large boobs and a Marilyn Monroe butt, which is not like Katara's body type at all. Azula's fanart picture I used looks like her real body shape, except she's in a sultry pose and is wearing a sexier swimsuit than her regular swimsuit.

^ I've noticed that about poor Katara. They seem to sexual her and Ty-Lee a real lot.
