Not an easy choice for me. Brook has my favorite background, Robin has my favorite personality, Zoro has the cool factor solidly in his corner, and each of the others has something interesting to bring to the table. I like Sanji (actually, more than I like Luffy) partially because his fighting style really intrigues me, partially because of his role as cook, but mostly because I really like the way he juxtaposes perversion with chivalry.

*If you haven't read the more recent mangas, don't read this last sentence*

I found the scene with Violet, when he was being beat to a pulp, to be the most telling. Despite all the perverted thoughts she saw in his head, that line "I will never question... a lady's tears!" stuck with me as being very solidly chivalrous, overlooking everything else he saw just to focus on something that could very easily have been fake. In many ways, he's a fool, but his solidity has won me over.

My favorite character.

My favorite character! Followed by Zoro.

i love everyone so it was really hard for me to pick but i think zoro is my favorite . i like nico robin after zoro because she has the same personality with me and chopper the third since he is really cute. i like others to since they have a bit of same personality with me. just a little bit.
I LOVE ONE PIECE THE SECOND THING IN MY LIFE!!!!!!!!!!!!!!!!!!!!!!!!!!!

She's my favorite character!<3 followed by Sanji,Zoro,Chopper and Robin!

Easy choice for me - Zoro has his badassery as a swordsman, owning three awesome blades and having an attitude that depicts epicness and confidence. I also love that he has such a habit of getting lost. To be fair, though, I do really like each character for different reasons, or rather, for reasons unique to each of them, I just find more reasons to like Zoro than the others, excluding Luffy.
