We know Aang and Zuko can bend and Katara's powerful, but what about in sheer skill? Who's the best martial artist in your opinion?

Iroh is the best, he really uses his mind. The others have teen problems to use much common sense in fighting.

Training wise without the use of bending I would have to say Suki and Zuko. Zuko proved himself as the Blue Spirit with the broadswords and Suki is good at tessenjujitsu (fighting with iron fans). I can't make up my mind of which is better

Without bending? Hmmm, I'd like to say Iroh but he is getting old and would have a difficult time depending of physical power alone. Its hard to make a decision cause all these martial artists on this show incorporate bending into their styles. The only person we've seen use just martial arts and no bending is Zuko. He strong, young, and kicks a lot of fanny w/ a pair of chinese broadswords. So I'd vote for Zuko.

I would vote Zuko since he fights well with and without weapons. I still haven't seen Iroh go all out yet but I'm sure he's one of the best. Suki is excellent as well as is Jet but they use their weapons too often. I have to see them fight without them to be really impressed.

I would love to see Jet and Zuko sword fight with the broadwords and the twin tiger daggers (Jets swords) Wow that would really make my day no joke. Or a Suki vs. Jun fight.

Hey, Jet is the only normal human who defeated a bender. Zuko might have his hands full.

geez i'm surprised no1 said Katara....she can kick some serious @$$! I mean, she has some serious waterbending skill, she kicked Zuko's @$$ didn't she? and he got a cheap shot on her so technically it didn't count. She is obviously more skilled with waterbending than most other people with the ability. I think katara is the best fighter.....with bending without it she's just like.....the foaming guy on kyoshi island....pointless. (in battle she isn't pointless)

Technically it wasn't a cheap shot. Zuko is stronger during the day and therefore easily overpowered Katara when he attacked her. Had it been night still, she could have easily deflected his fire blast.

Iroh.

He was there to remind why not to do drugs lol... learn something from that

id go with zuko or ahem EDWARD ELRIC

With the information that we have so far about Azula (season 2 spoilers I'm not going to repost them here to ruin your fun) I'd but her at the top of list too, even though she has a small figure if you could say that, she is going GOING TO PACK A PUNCH. My votes in for her too.
