Where am I? Who am I? What am I?

I've been wandering, doing menial jobs and staying alive! That pig sty was disgusting, I may never eat pork again! Wandering for how long? Where am wandering to? What is happening to my mind? Every so often I feel something well up inside my body to focus on my brain and then...weird things happen. I use to pass out when this happened, but now it's just a headache, and what I observe is wonderful and frightening at the same time...I can make puddles and streams of water move, dance and even freeze! I can control flames and make tiny fire puppets dance atop the campfire! I can even make fire burst from a torch or candle or the campfire! These things scare people or cause damage (like that barn, it wasn't my fault)! I can't explain it. And then they run me off!
Maybe that's better, what if I hurt or even killed someone. Agghhh what do you want, I don't understand you..what cage? Shut up! Shut up!
 
We'll see what theses traveling circus folk are all about! Maybe they won't be put off by the things I do? I can't be any weirder than a side show, can I? Aghhhh!!! Wait, I can hear you...you're different than the one before! Different than the disgusting... My neck...my neck! What is that? What is this purple slime! Gross! I wonder why they call me Nin Law...I don't understand, |But I do| Hello, who are you? Hey! You let her alone...my god what did you do!!!!
