Oh man sooo many choices. Well I will list a few.
Nancy from R.O.D. I mean come on, how awsome would it be to be able to go through anything. You could do anything. You could be like punch me, I dare you, then when they punch let their hand go through you right into a wall

. Not to mention Nancy is a Hotty.
The Paper from R.O.D. It would be awsome to be able to control paper. Imagin the fun you could have

.
Ryoko from Tenchi. I would love to be that hot, that cool, be able to kick anyone's ass, and on top of all that, never get a day older. Pretty much a hotty for life. Plus she lives a life of fun at Tenchi's house. Plus like Ryoko I too like to drink and eat

.
I would also like to agree with bobbarker on Misato. Bews, Ramen, a Penguin, and Evas. What a life
