She is a very intense and serious person, but the other words describe her quite well too. XD

Captain Bitchninja.

LOL!!! XDDD. Your comment wins.

Sorry- I had to add this, I could not resist, but I do think she is serious and intense, really TOO much so for her own good XD

I'm seriously feel like I'm the only one who sees this side of her T.T Honestly, her grin is so epic, it's on par with the ones in Pandora Hearts. It may even be up there with Lacie's! Ever time I see that smile, I expect someone to get more pwned than they do. Sometimes I feel like they need to revamp Soi Fon to match her own smile and attitude. Her love for Yoruichi is a pain and clearly used solely for comic relief. If they could just give her assassin technique more EPICNESS and turn he obsession into a strong loyalty, then my favorite captain would be all the more awesome XD

But that just goes up to her shikai. At the moment, i think she's the captain with the most OP bankai. It's like Marth's Final Smash in SSBB. If it hits, unless you've got some tricks, or you're lucky, you're f***ed

@Exorcist, I kinda see what you mean, dude. XD

Strangely I find Soi Fon to be beautiful but she can be serious,quick,intense,strong & powerful at times too!

Serious indeed~
