Who is/are your favorite anime character(s), and why?

Lastly - Lucy from Elfen Lied, just because she totally kicks ass.

Lucy is pretty cool as for the character, but I hated how both the anime and manga ended (the anime ending is better than the manga ending though). I was rooting for an ending where everyone ends up together . The way the manga ended though was just dumb..... having her melt away???
